Title: System and method of sentiment data use

Description:
RELATED APPLICATIONS 
     The present application claims the benefit of U.S. Provisional Patent Application No. 61/506,584, filed Jul. 11, 2011, entitled “SENTIMENT INDEXING,” naming Hong Liang Qiao as the inventor. That application is incorporated herein by reference in its entirety and for all purposes. 
     The present application is related to U.S. patent application Ser. No. 13/452,718, filed Apr. 20, 2012, entitled “SYSTEM AND METHOD OF SENTIMENT DATA GENERATION,” naming Hong Liang Qiao as the inventor. That application is incorporated herein by reference in its entirety and for all purposes. 
    
    
     BACKGROUND OF THE INVENTION 
     Conventional search engines commonly use keywords from a user-input search query to locate and display webpages. For example, if a user were interested in learning about which countries border the United States, the user may enter a search query of “country bordering United States.” In response, a conventional search engine would typically return webpages with all or some of the four words “country,” “bordering,” “United,” and “States.” 
     Although conventional search engines may be used to locate webpages that contain certain words, it is difficult or impossible to determine sentiment using conventional search engines. For example, if a user wants to learn about people&#39;s opinions of the performance of the Toyota Land Cruiser, a search query may be input that includes the words “Toyota Land Cruiser” and “performance.” However, such a query would typically cause a conventional search engine to return many irrelevant webpages which contain information other than the sentiment of the performance of the Toyota Land Cruiser. As such, a user must wade through a large number of search results to find the desired sentiment if at all. Thus, determining sentiment using a conventional search engine is difficult and inefficient. 
     SUMMARY OF THE INVENTION 
     Accordingly, a need exists to more readily determine sentiment associated with one or more portions of at least one document. A need also exists to more efficiently determine sentiment associated with one or more portions of at least one document. Embodiments of the present invention provide novel solutions to these needs and others as described below. 
     Embodiments of the present invention are directed to a method, computer-readable medium, and a computer system for processing data. More specifically, first data associated with a search may be accessed. The first data may include at least a portion of a query used for the search to generate search results, at least one command associated with the search (e.g., accessed and/or used by a search component to generate and/or process search results such as at least one category associated with at least one sentiment, at least one degree associated with at least one sentiment, at least one classification associated with at least one sentiment, etc.), information associated with the search results, some combination thereof, etc. Second data may be accessed from a database using the first data, where the second data may be associated with at least one sentiment of the first data. The second data may include at least one score, at least one classification, and at least one degree, some combination thereof, etc. Additionally, third data may be generated, based on the second data, for performing at least one operation associated with the search results. The at least one operation may include filtering the search results, ranking the search results, displaying an image associated with the at least one sentiment (e.g., a background or other feature of a webpage which indicates a sentiment associated with a plurality of search results, a background or other feature of a particular search result which indicates a sentiment associated with the particular search result or some portion thereof, an image displayed separate from the search results which indicates a sentiment associated with one or more of the search results or some portion thereof, etc.), some combination thereof, etc. 
     In one embodiment, a method of processing data includes accessing first data associated with a search, wherein said search is operable to generate search results comprising at least one document. Second data is accessed, using said first data, from a database, wherein said second data is associated with at least one sentiment of said first data. Third data is generated, based on said second data, for performing at least one operation associated with said search results. 
     In another embodiment, a computer-readable medium may have computer-readable program code embodied therein for causing a computer system to perform a method of processing data. And in yet another embodiment, a system may include a processor and a memory, wherein the memory includes instructions that when executed by the processor implement a method of processing data.

     Embodiments of the Present Invention 
     In one embodiment, data associated with sentiment of one or more portions of at least one document may be generated (e.g., in accordance with process  100  of  FIGS. 1A, 1B and 1C , using one or more components of system  200  of  FIG. 2 , using one or more components of processing component  220  of  FIG. 3 , etc.). The data may include at least one score (e.g., as shown in  FIGS. 4, 5, 6A, 6B, 6C, 7A, 7B, 8A, 8B, 9, 10 , etc.), at least one category (e.g., as shown in  FIGS. 4, 5, 6A, 6B, 6C, 7A, 7B, 8A, 8B, 9, 10 , etc.), at least one degree (e.g., as shown in  FIGS. 4, 5, 6A, 6B, 6C, 7A, 7B, 8A, 8B, 9, 10 , etc.), at least one classification (e.g., as shown in  FIG. 10 ), or some combination thereof. The data may be modified or changed (e.g., a score may be reduced if portions of a document being scored are part of the same phrase or name as depicted in  FIGS. 6A, 6B and 6C ; a score may be reduced if one portion of a phrase or name causes another portion of the phrase or name to be scored as depicted in  FIGS. 7A and 7B ; sentiment data may be added for a name or phrase by combining or using information associated with portions of the name or phrase as depicted in  FIGS. 8A and 8B ; sentiment data may be added for a theme or semantic key by combining or using information associated with theme elements or semantic sub-keys as depicted in  FIG. 9 ; sentiment data may be added for a theme or semantic key by combining or using information associated with theme elements or semantic sub-keys as depicted in  FIG. 9 ; etc.) in one embodiment. And in one embodiment, the data may be stored (e.g., in a database or index for subsequent use). 
     Data associated with sentiment of one or more portions of at least one document may be accessed (e.g., in accordance with process  1100  of  FIG. 11 , using one or more components of system  1300 A of  FIG. 13A , etc.) and/or used (e.g., in accordance with process  1200  of  FIG. 12 , using one or more components of system  1300 B of  FIG. 13B , etc.) in one embodiment. For example, data associated with sentiment of one or more portions of at least one document may be accessed from a database using data associated with a search (e.g., a query used for the search to generate search results, information associated with the search results, at least a portion of the search results, at least one command, etc.). The data associated with the search may be input (e.g., by a user) using a user interface (e.g., graphical user interface  1400 A of  FIG. 14A , graphical user interface  1400 B of  FIG. 14B , graphical user interface  1500  of  FIG. 15 , etc.) in one embodiment. The data may be used to generate other data for performing at least one operation associated with search results (e.g., generated as a result of the search). The at least one operation may include filtering the search results, ranking the search results, displaying an image associated with the at least one sentiment (e.g., a background or other feature of a webpage which indicates a sentiment associated with a plurality of search results, a background or other feature of a particular search result which indicates a sentiment associated with the particular search result or some portion thereof, an image displayed separate from the search results which indicates a sentiment associated with one or more of the search results or some portion thereof, etc.), some combination thereof, etc. The image may be displayed using and/or as part of a graphical user interface (e.g.,  1600 A of  FIG. 16A, 1600B  of  FIG. 16B, 1600C  of  FIG. 16C , etc.) in one embodiment. 
     Generation of Sentiment Data 
       FIGS. 1A, 1B and 1C  show a flowchart of computer-implemented process  100  for automatically generating sentiment data in accordance with one embodiment of the present invention.  FIG. 2  shows exemplary system  200  for analyzing sentiment in accordance with one embodiment of the present invention. As shown in  FIG. 2 , sentiment analysis component  220  may analyze sentiment associated with at least one document  210  (or at least one portion thereof) to generate data associated with the sentiment of one or more portions of at least one document  210  (e.g., “sentiment data”), where the sentiment data may be stored in sentiment index or database  230  in one embodiment. Sentiment database  230  may include one or more data structures (e.g.,  400 ,  500 ,  600 A,  600 B,  600 C,  700 A,  700 B,  800 A,  800 B,  900 ,  1000 , some combination thereof, etc.).  FIG. 3  shows components of exemplary sentiment analysis component  220  in accordance with one embodiment of the present invention. 
     Turning to  FIG. 1A , step  105  involves determining a first portion of at least one document that is associated with a first sentiment of a second portion of the at least one document. For example, where a document includes the sentence “the weather is very good,” step  105  may involve determining that “very good” (e.g., the first portion) is associated with a sentiment of “weather” (e.g., the second portion). 
     In one embodiment, step  105  may involve determining that the first portion effects or modifies the second portion, or conversely, that the second portion is affected by the first portion. In one embodiment, step  105  may involve determining (e.g., using a grammatical analyzer) that the first and second portions are within the same sentence, within the same sentence fragment, within the same paragraph, within a predetermined proximity (e.g., defined in terms of a number of words, a number of sentences, a number of paragraphs, etc.) to one another in a document, etc. In one embodiment, step  105  may involve determining (e.g., using a grammatical analyzer) that the first and second portions are within different sentences, within different sentence fragments, within different paragraphs, outside of a predetermined proximity (e.g., defined in terms of a number of words, a number of sentences, a number of paragraphs, etc.) to one another in a document, etc. And in one embodiment, step  105  may involve determining (e.g., using a grammatical analyzer) that the first and second portions are grammatically related (e.g., subject and predicate, subject and verb, verb and object, noun and adjective, pronoun and adjective, noun and adverb, pronoun and adverb, etc.). It should be appreciated that the first portion and the second portion may be any part of speech (e.g., a noun, verb, pronoun, adjective, adverb, preposition, conjunction, interjection, etc.), where the first and second portions may be the same part of speech (e.g., both nouns, both verbs, etc.) or different parts of speech. 
     In one embodiment, the first portion and/or second portion may be included in a sentence or sentence fragment that does not form a question. For example, when parsing a document to locate or identify the first portion and/or second portion, sentences or sentence fragments forming questions may be skipped in one embodiment. 
     In one embodiment, the first portion and/or the second portion of the at least one document may include at least one respective word. The first and second portions may be in the same document, or alternatively, may be in different documents in one embodiment. The at least one document may include at least one webpage, at least one electronic document, at least one electronic file, advertising content, some combination thereof, etc. 
     As shown in  FIG. 1A , step  110  involves automatically determining, based on at least one attribute of the first portion, a first score associated with the first sentiment of the second portion. In one embodiment, the at least one attribute of the first portion may be a category (e.g., positive, negative, neutral, etc.) associated with the first sentiment. For example, “very good” in the previous example may be determined to belong to or otherwise be associated with a positive category in step  110 . As another example, “bad” or “very bad” may be determined to belong to or otherwise be associated with a negative category in step  110 . And as yet another example, “so-so” or “average” may be determined to belong to or otherwise be associated with a neutral category in step  110 . In this manner, the first score (e.g., associated with the first sentiment of the second portion) determined in step  110  may be positive, negative, or neutral based on at least one attribute of the first portion. 
     In one embodiment, the at least one attribute of the first portion may be a degree associated with the first sentiment. For example, “very good” in the previous example may be determined to be associated with a medium degree or a particular numerical degree (e.g., 2 out of 3, where 1 may be a low degree, 2 may be a medium degree and 3 may be a high degree) in step  110 . As another example, “excellent” may be determined to be associated with a high degree or a particular numerical degree (e.g., 3 out of 3, where 1 may be a low degree, 2 may be a medium degree and 3 may be a high degree) in step  110 . And as yet another example, “good” may be determined to be associated with a low degree or a particular numerical degree (e.g., 1 out of 3, where 1 may be a low degree, 2 may be a medium degree and 3 may be a high degree) in step  110 . 
     Although degrees associated with positive sentiments have been discussed in the previous examples, it should be appreciated that degrees may also be associated with negative sentiments. Additionally, although specific degrees have been discussed (e.g., low, medium, high, certain numerical degrees, etc.), it should be appreciated that a different number of degrees (e.g., less than or more than 3, etc.) or different types of degrees may be used in other embodiments. 
     As shown in  FIG. 1A , step  115  involves determining a third portion of the at least one document that is associated with a second sentiment of a fourth portion of the at least one document. For example, where a document includes the sentence “the water is bad,” step  115  may involve determining that “bad” (e.g., the third portion) is associated with a sentiment of “water” (e.g., the fourth portion). 
     In one embodiment, step  115  may involve determining that the third portion effects or modifies the fourth portion, or conversely, that the fourth portion is affected by the third portion. In one embodiment, step  115  may involve determining (e.g., using a grammatical analyzer) that the third and fourth portions are within the same sentence, within the same sentence fragment, within the same paragraph, within a predetermined proximity (e.g., defined in terms of a number of words, a number of sentences, a number of paragraphs, etc.) to one another in a document, etc. In one embodiment, step  115  may involve determining (e.g., using a grammatical analyzer) that the third and fourth portions are within different sentences, within different sentence fragments, within different paragraphs, outside of a predetermined proximity (e.g., defined in terms of a number of words, a number of sentences, a number of paragraphs, etc.) to one another in a document, etc. And in one embodiment, step  115  may involve determining (e.g., using a grammatical analyzer) that the third and fourth portions are grammatically related (e.g., subject and predicate, subject and verb, verb and object, noun and adjective, pronoun and adjective, noun and adverb, pronoun and adverb, etc.). It should be appreciated that the third portion and the fourth portion may be any part of speech (e.g., a noun, verb, pronoun, adjective, adverb, preposition, conjunction, interjection, etc.), where the third and fourth portions may be the same part of speech (e.g., both nouns, both verbs, etc.) or different parts of speech. 
     In one embodiment, the third portion and/or fourth portion may be included in a sentence or sentence fragment that does not form a question. For example, when parsing a document to locate or identify the third portion and/or fourth portion, sentences or sentence fragments forming questions may be skipped in one embodiment. 
     In one embodiment, the third portion and/or the fourth portion of the at least one document may include at least one respective word. The third and fourth portions may be in the same document, or alternatively, may be in different documents in one embodiment. The at least one document may include at least one webpage, at least one electronic document, at least one electronic file, advertising content, some combination thereof, etc. 
     As shown in  FIG. 1A , step  120  involves automatically determining, based on at least one attribute of the third portion, a second score associated with the second sentiment of the fourth portion. In one embodiment, the at least one attribute of the third portion may be a category (e.g., positive, negative, neutral, etc.) associated with the second sentiment. For example, “bad” in the previous example may be determined to belong to or otherwise be associated with a negative category in step  120 . As another example, “good” or “very good” may be determined to belong to or otherwise be associated with a positive category in step  120 . And as yet another example, “so-so” or “average” may be determined to belong to or otherwise be associated with a neutral category in step  120 . In this manner, the second score (e.g., associated with the second sentiment of the fourth portion) determined in step  120  may be positive, negative, or neutral based on at least one attribute of the third portion. 
     In one embodiment, the at least one attribute of the third portion may be a degree associated with the second sentiment. For example, “bad” in the previous example may be determined to be associated with a low degree or a particular numerical degree (e.g., 1 out of 3, where 1 may be a low degree, 2 may be a medium degree and 3 may be a high degree) in step  120 . As another example, “very bad” may be determined to be associated with a medium degree or a particular numerical degree (e.g., 2 out of 3, where 1 may be a low degree, 2 may be a medium degree and 3 may be a high degree) in step  120 . And as yet another example, “extremely bad” may be determined to be associated with a high degree or a particular numerical degree (e.g., 3 out of 3, where 1 may be a low degree, 2 may be a medium degree and 3 may be a high degree) in step  120 . 
     Although degrees associated with negative sentiments have been discussed in the previous examples, it should be appreciated that degrees may also be associated with positive sentiments. Additionally, although specific degrees have been discussed (e.g., low, medium, high, certain numerical degrees, etc.), it should be appreciated that a different number of degrees (e.g., less than or more than 3, etc.) or different types of degrees may be used in other embodiments. 
     In one embodiment, steps  105  and/or  115  of process  100  may be performed by portion determination component  310  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). And in one embodiment, steps  110  and/or  120  of process  100  may be performed by score determination component  320  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). 
       FIG. 4  shows exemplary data structure  400  including sentiment data (e.g., data associated with sentiment of one or more portions of at least one document) in accordance with one embodiment of the present invention. As shown in  FIG. 4 , each row of data structure  400  may include respective score data (e.g., in column  470 ) that is associated with a respective effecting portion (e.g., in column  450 ) and/or a respective affected portion (e.g., in column  410 ). In one embodiment, one or more of the effecting portions (e.g., in column  450 ) may be analogous to the first portion (e.g., determined in step  105  of process  100 ) and/or the third portion (e.g., determined in step  115  of process  100 ), whereas one or more of the affected portions (e.g., in column  410 ) may be analogous to the second portion and/or the fourth portion. In this manner, each of the effecting portions (e.g., in column  450 ) may be associated with a respective sentiment (e.g., associated with the score data in column  470 ) of a respective affected portion (e.g., in column  410 ). 
     As shown in  FIG. 4 , one or more columns of data structure  400  (e.g., columns  420 ,  430  and  440 ) may provide a respective location of each affected portion in column  410 . For example, column  420  may include a respective document identifier associated with each affected portion in column  410 , column  430  may include a respective sentence identifier (e.g., a sentence number or numbers, etc.) associated with each affected portion in column  410 , and column  440  may include a respective affected portion identifier (e.g., a word number or numbers, etc.) associated with each affected portion in column  410 . As a further example, the first row in data structure  400  may correspond to the first sentence in Document “ 1 ” which reads: “[t]he weather is very good.” In this case, the word “weather” may be an affected portion (e.g., modified or affected by the effecting portion “very good”) located in the second word of the first sentence of Document “ 1 .” 
     One or more columns of data structure  400  (e.g., columns  420 ,  430  and  460 ) may provide a respective location of each effecting portion in column  450 . For example, column  420  may include a respective document identifier associated with each effecting portion in column  450 , column  430  may include a respective sentence identifier (e.g., a sentence number or numbers, etc.) associated with each effecting portion in column  450 , and column  460  may include a respective effecting portion identifier (e.g., a word number or numbers, etc.) associated with each effecting portion in column  450 . Using the above example where the first sentence in Document “ 1 ” reads “[t]he weather is very good,” the words “very good” may be an effecting portion (e.g., associated with a sentiment of the affected word “weather”) located in the fourth and fifth words of the first sentence of Document “ 1 .” 
     As shown in  FIG. 4 , each portion of score data in column  470  may include at least one respective score (e.g., determined in accordance with step  110  and/or step  120  of process  100 ). Each score may be determined by at least one respective attribute (e.g., a category, a degree, etc.) of a respective effecting portion (e.g., in column  450 ). For example, the score of “+2” in the first row may be determined based on a positive category and a degree of 2 associated with the effecting portion of “very good.” As another example, the score of “−1” in the second row may be determined based on a negative category and a degree of 1 associated with the effecting portion of “bad.” As yet another example, the score of “0” in the third row may be determined based on a neutral category and/or a degree of 0 associated with the effecting portion of “so-so.” 
     Accordingly, data structure  400  may be used to access or determine data associated with sentiment of one or more portions of at least one document (e.g., by indexing a database or index including data structure  400 ). For example, where one or more affected portions within data structure  400  are associated with “Toyota Land Cruiser,” the sentiment of the Toyota Land Cruiser may be easily and efficiently determined by indexing data structure  400  (e.g., using the affected portion “Toyota Land Cruiser”) to access sentiment data associated with the Toyota Land Cruiser (e.g., indicating opinions or feelings about the Toyota Land Cruiser which may be positive, negative, neutral, positive of a certain degree, negative of a certain degree, etc.). The sentiment data may be determined from a plurality of documents or sources in one embodiment, thereby increasing the reliability and/or accuracy of the data accessed. Additionally, in one embodiment, the sentiment data may be further processed (e.g., to determine sentiment associated with a larger portion of a document, to determine sentiment associated with an entire document, to determine sentiment associated with a plurality of documents, etc.) to provide further information and/or analysis as discussed herein. 
     Turning to  FIG. 1B , step  125  involves determining a respective score for each document of the at least one document. Step  125  may be performed by score determination component  320  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ) in one embodiment. 
     In one embodiment, step  125  may involve determining at least one respective score (e.g., a respective positive score, a respective negative score, a respective neutral score, some combination thereof, etc.) for each document of the at least one document. A positive score may be determined for a document by adding or combining each of the positive scores for a plurality of affected portions of the document (e.g., a document with two affected portions each with a respective score of “+2” may result in a combined positive score for the document of “4”), based on the number of affected portions of the document associated with a positive score (e.g., a document with 10 affected portions associated with positive scores may result in a combined positive score for the document of “10”), etc. A negative score may be determined for a document by adding or combining each of the negative scores for a plurality of affected portions of the document (e.g., a document with two affected portions each with a respective score of “−1” may result in a combined negative score for the document of “2”), based on the number of affected portions of the document associated with a negative score (e.g., a document with 15 affected portions associated with negative scores may result in a combined negative score for the document of “15”), etc. A neutral score may be determined by combining the positive and negative scores (e.g., a document with two affected portions with scores of “+2” and “−2” may result in a combined neutral score of “0”), based on the number of affected portions of the document associated with a neutral score (e.g., a document with 5 affected portions associated with neutral scores may result in a combined neutral score for the document of “5”), etc. 
       FIG. 5  shows exemplary data structure  500  including sentiment data for at least one document in accordance with one embodiment of the present invention. As shown in  FIG. 5 , each row of data structure  500  may include at least one respective score (e.g., a positive score in column  520 , a negative score in column  530 , a neutral score in column  540 , a net score in column  550 , some combination thereof, etc.) for a respective document (e.g., in column  510 ). In one embodiment, one or more of the scores in columns  520 ,  530  and/or  540  may be determined based on a number of affected portions of a document that are associated with each category (e.g., positive, negative, neutral, etc.), a percentage of the affected portions of a document that are associated with each category (e.g., positive, negative, neutral, etc.), etc. For example, in one embodiment, the numbers in columns  520 ,  530  and  540  for any given row may add to 100 indicating that 100 percent of the affected portions of the document are accounted for in the data of these columns (e.g.,  520 ,  530  and  540 ). In one embodiment, one or more of the scores in column  520  may be determined by adding or combining respective positive scores of respective affected portions of each document. One or more of the scores in column  530  may be determined by adding or combining respective negative scores of respective affected portions of each document in one embodiment. And in one embodiment, one or more of the scores in column  550  may be determined by adding or combining a respective positive score (e.g., in column  520 ) with a respective negative score (e.g., in column  530 ) for each document. 
     Accordingly, data structure  500  may be used to access or determine data associated with sentiment of at least one document (e.g., by indexing a database or index including data structure  500 ). The sentiment data (e.g., positive sentiment data in column  520 , negative sentiment data in column  530 , neutral sentiment data in column  540 , etc.) may be used, for example, in combination with a search (e.g., to generate search results including one or more documents listed in column  510  of data structure  500 ) to determine the sentiment of something (e.g., identified in the query for the search) across the one or more documents of the search results. Additionally, the net sentiment data (e.g., in column  550 ) may allow a determination of whether the overall sentiment for each document is positive or negative and/or how positive or negative the sentiment is. In this manner, a larger amount of data may be advantageously represented in a more concise and/or comprehensible manner (e.g., when presenting the data using a webpage, graphical user interface, etc.) as discussed herein. 
     Turning back to  FIG. 1B , step  125  may involve determining at least one score (e.g., a positive score, a negative score, a neutral score, some combination thereof, etc.) for a plurality of documents in one embodiment. The at least one score may be determined by combining, adding, etc. the data of data structure  400  and/or data structure  500 . In this manner, sentiment data for a plurality of documents (e.g., included within or otherwise associated with search results) may be easily and/or efficiently determined (e.g., which may be used to indicate sentiment of search results or a portion thereof, etc.). 
     Step  130  involves adjusting the first score (e.g., determined in step  110 ) and/or the second score (e.g., determined in step  120 ) if one or more conditions are met. Step  130  may be performed by score adjustment component  330  (either alone or in combination with grammatical analysis component  340 ) of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ) in one embodiment. In one embodiment, grammatical analysis component  340  may be used to determine if a plurality of portions of at least one document are associated with the same name, phrase or other grammatical unit. 
     In one embodiment, step  130  may involve reducing one or more of a plurality of scores associated with a plurality of affected portions if the plurality of affected portions is associated with the same name, phrase or other grammatical unit and also is associated with a plurality of effecting portions that are the same (e.g., causing the plurality of scores to result from the same effecting portion). For example,  FIGS. 6A, 6B and 6C  show exemplary data structures (e.g.,  600 A,  600 B and  600 C, respectively) illustrating a score reduction resulting from affected portions being associated with the same name, phrase or other grammatical unit and also being associated with the same effecting portion in accordance with one embodiment of the present invention. 
     As shown in  FIG. 6A , data structure  600 A may include sentiment data associated with the affected portions “John” and “Smith” which may be part of the name or phrase “John Smith.” Both “John” and “Smith” are associated with a score of “+1” based on at least one attribute of the same effecting portion “good.” Accordingly, since both “John” and “Smith” (e.g., the plurality of affected portions) are associated with the same name or phrase and also are associated with the same effecting portion “good,” the score associated with either affected portion (e.g., “John” or “Smith”) may be reduced. For example,  FIG. 6B  shows a reduction of the score associated with the affected portion “Smith,” while  FIG. 6C  shows a reduction of the score associated with the affected portion “John.” In this manner, the overall score for the name or phrase “John Smith” will be only “+1” (based on the effecting portion “good”) instead of the artificially high score of “+2” that would otherwise result from combining the respective “+1” scores if one of the scores had not been reduced. 
     Although  FIGS. 6A, 6B and 6C  only depict a name or phrase with two words, it should be appreciated that a name, phrase or other grammatical unit may include more than two words in other embodiments. In this case, more than one score may be reduced in step  130  if the affected portions are associated with the same effecting portion (e.g., causing the scores to result from the same effecting portion). 
     In one embodiment, step  130  may involve reducing at least one score associated with at least one affected portion if the at least one affected portion and a corresponding at least one effecting portion are associated with the same name, phrase or other grammatical unit. For example,  FIGS. 7A and 7B  show exemplary data structures (e.g.,  700 A and  700 B, respectively) illustrating a score reduction resulting from an affected portion and a corresponding effecting portion being associated with the same name, phrase or other grammatical unit in accordance with one embodiment of the present invention. 
     As shown in  FIG. 7A , data structure  700 A may include sentiment data associated with the affected portions “National,” “Day,” “Celebration” and “Committee” which may be part of the name or phrase “National Day Celebration Committee.” Accordingly, since both “Committee” (e.g., the affected portion) and “Celebration” (e.g., the corresponding effecting portion) are associated with the same name or phrase, the score associated with the affected portion “Committee” may be reduced as illustrated in  FIG. 7B . 
     Although  FIGS. 7A and 7B  only depict the reduction of one score, it should be appreciated that any number of scores may be reduced in other embodiments. For example, where a plurality of affected portions and at least one corresponding effecting portion are associated with the same name, phrase or other grammatical unit, then a plurality of scores (e.g., associated with the plurality of affected portions) may be reduced in step  130 . 
     In one embodiment, step  130  may involve increasing or combining scores associated with a plurality of affected portions if the plurality of affected portions is associated with the same name, phrase or other grammatical unit and also is associated with a plurality of effecting portions that are the different (e.g., causing the plurality of scores to result from different effecting portions). For example,  FIGS. 8A and 8B  show exemplary data structures (e.g.,  800 A and  800 B, respectively) illustrating a score combination or increase resulting from affected portions being associated with the same name, phrase or other grammatical unit and also being associated with different effecting portions in accordance with one embodiment of the present invention. 
     As shown in  FIG. 8A , data structure  800 A may include sentiment data associated with the affected portions “John” and “Smith” which may be part of the name or phrase “John Smith.” Both “John” and “Smith” are associated with a score of “+1” based on at least one respective attribute of the effecting portions “nice” and “help.” Accordingly, since both “John” and “Smith” (e.g., the plurality of affected portions) are associated with the same name or phrase and also are associated with the different effecting portions “nice” and “help,” the scores associated with the affected portions (e.g., “John” and “Smith”) may be combined or increased. For example,  FIG. 8B  shows the respective scores of “+1” for “John” and “Smith” have been combined or increased to form the score of “+2” associated with the name or phrase “John Smith.” 
     Although  FIG. 8B  shows the addition of data to data structure (e.g., the last row associated with the name or phrase “John Smith”), it should be appreciated that scores may be combined or increased in other manners in other embodiments. For example, the score associated with either “John” or “Smith” may be increased from “+1” to “+2” in one embodiment. 
     Turning back to  FIG. 1B , step  135  involves determining that the second portion and the fourth portion are theme elements associated with a theme and/or are semantic sub-keys associated with a semantic key. In one embodiment, a theme associated with the second and fourth portions (e.g., as theme elements) may be determined in step  135  in accordance with U.S. patent application Ser. No. 12/884,395, filed Sep. 17, 2010, and entitled “METHOD AND SYSTEM FOR SCORING TEXTS.” In one embodiment, a semantic key associated with the second and fourth portions (e.g., as semantic sub-keys) may be determined in step  135  in accordance with U.S. patent application Ser. No. 12/112,774, filed Apr. 30, 2008, entitled “SYSTEM AND METHOD FOR ENHANCING SEARCH RELEVANCY USING SEMANTIC KEYS” and/or in accordance with U.S. patent application Ser. No. 13/012,690, filed Jan. 24, 2011, entitled “IMPROVED SEARCHING USING SEMANTIC KEYS.” 
     As an example, where the second portion includes the word “apple” and the fourth portion includes the word “cherry,” step  135  may involve determining that the second portion (e.g., the word “apple”) and the fourth portion (e.g., the word “cherry”) are theme elements associated with the theme “fruit.” As another example, where the second portion includes the word “apple” and the fourth portion includes the word “cherry,” step  135  may involve determining that the second portion (e.g., the word “apple”) and the fourth portion (e.g., the word “cherry”) are semantic sub-keys associated with the semantic key “fruit.” 
     In one embodiment, the theme or the semantic key that are determined in step  135  may not be an affected portion of the at least one document including the second portion and/or the fourth portion. And in one embodiment, the theme or the semantic key that are determined in step  135  may not be included in any portion of the at least one document including the second portion and/or the fourth portion. 
       FIG. 9  shows exemplary data structure  900  including sentiment data for a theme and/or a semantic key in accordance with one embodiment of the present invention. As shown in  FIG. 9 , data structure  900  may include respective score data (e.g., in column  940 ) for each theme element and/or semantic sub-key (e.g., in column  930 ). The theme elements and/or semantic sub-keys in column  930  may be one or more affected portions (e.g., described with respect to other Figures) of at least one document (e.g., in column  910 ) in one embodiment. 
     Column  920  may include at least one theme and/or at least one semantic key associated with the theme elements and/or semantic sub-keys in column  930  (e.g., as determined in step  135 ). For example, the theme or semantic key “fruit” in document “ 1 ” (depicted in  FIG. 9  in the first row of data structure  900 ) may be determined in step  135  based on one or more of the associated portions (e.g., affected portions, theme elements, semantic sub-keys, some combination thereof, etc.) in column  930  (e.g., “apple,” “cherry,” “pineapple,” some combination thereof, etc.). In one embodiment, the information in column  920  may be added to data structure  900  after the information in column  930  (e.g., responsive to performing step  135 ). 
     As shown in  FIG. 1B , step  140  involves determining a third score associated with the theme and/or the semantic key. In one embodiment, the third score may be determined in step  140  based on the sentiment data of the corresponding theme elements and/or semantic sub-keys (e.g., in column  930  of data structure  900 ). In one embodiment, the third score determined in step  140  may include at least a portion of the combined score data (e.g., a combined positive sentiment score, a combined negative sentiment score, a net sentiment score, some combination thereof, etc.) in column  950  of data structure  900  of  FIG. 9 . 
     As shown in  FIG. 9 , data structure may include respective combined score data in column  950  for each of the documents in column  910  and/or each of the themes or semantic keys in column  920 . For example, the combined score data associated with document “ 2 ” may include a combined positive sentiment score (e.g., “+2” determined in step  140  by adding or averaging the positive scores of “+1” and “+1” from the corresponding score data in column  940 ), a combined negative sentiment score (e.g., “−2” determined in step  140  by adding or averaging the negative scores of “−2” from the corresponding score data in column  940 ), a net sentiment score (e.g., determined in step  140  by averaging or adding the combined positive sentiment score and the combined negative sentiment score), some combination thereof, etc. In other embodiments, different or other sentiment data (e.g., other score data, other combined score data, classification data, etc.) may be included in column  950  or another column of data structure  900 . 
     In one embodiment, step  135  of process  100  may be performed by theme or semantic key determination component  350  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). And in one embodiment, step  140  of process  100  may be performed by score determination component  320  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). 
     As shown in  FIG. 1C , step  145  involves determining at least one classification associated with the first portion (e.g., determined in step  105 ) and/or the third portion (e.g., determined in step  115 ). The at least one classification may explain why a sentiment of a portion was determined (e.g., in step  110 , in step  120 , etc.) to be in a certain category (e.g., positive, negative, neutral, etc.), to have a certain degree (e.g., 1, 2, 3, 4, low, medium, high, etc.), etc. In one embodiment, the at least one classification may be an action taker (e.g., a positive action taker such as a benefactor, a negative action taker such as an offender, etc.), an action receiver (e.g., a positive action receiver such as a beneficiary, a negative action receiver such as a victim, etc.), a description (e.g., a positive description, a negative description, etc.), an identity (e.g., a positive identity such as Superman or The Red Cross, a negative identity such as Hitler or Nazi, etc.), etc. And in one embodiment, step  145  may be performed by classification determination component  360  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). 
       FIG. 10  shows exemplary data structure  1000  including classification data associated with score data in accordance with one embodiment of the present invention. As shown in  FIG. 10 , each row of data structure  1000  may include respective score data (e.g., in column  1030 ) that is associated with a respective effecting portion (e.g., in column  1020 ) and/or a respective affected portion (e.g., in column  1010 ). Additionally, data structure  1000  may also include respective classification data (e.g., in column  1040 ) associated with each score data (e.g., in column  1030 ) and/or each affected portion (e.g., in column  1010 ). 
     Taking the first and second rows of data structure  1000  (e.g., associated with the sentence “Tom hit Chuck”) as an example, the effecting portion “hit” (e.g., in column  1020 ) may be associated with a sentiment of at least one affected portion (e.g., “Tom” in column  1010 , “Chuck” in column  1010 , etc.). A sentiment score of “−1” (e.g., as shown in column  1030 ) may be determined (e.g., in step  110 , step  120 , etc.) based on at least on attribute of the effecting portion (e.g., the word “hit” which may be associated with a negative sentiment or category, the lack of a modifier for the word “hit” may be associated with a degree of “1,” etc.). Additionally, a respective classification (e.g., “Negative Action Taker; Hurt” as shown in column  1040 , “Negative Action Receiver; Hurt” as shown in column  1040 , etc.) associated with each affected portion (e.g., “Tom” in column  1010 , “Chuck” in column  1010 , etc.) and/or each effecting portion (e.g., “hit” as shown in column  1020 ) may be determined in step  145 . In this manner, the classification data (e.g., in column  1040 ) may explain or otherwise be associated with why score data (e.g., a category, a degree, a score, other sentiment data, etc.) was determined for an affected portion (e.g., in column  1010 ) and/or an effecting portion (e.g., in column  1020 ). The classification data may also explain why a sentiment (e.g., associated with the score data in column  1030 ) of at least one affected portion (e.g., “Tom” in column  1010 , “Chuck” in column  1010 , etc.) was determined (e.g., in step  110 , in step  120 , etc.) to be in a certain category (e.g., positive, negative, neutral, etc.), to have a certain degree (e.g., 1, 2, 3, 4, low, medium, high, etc.), etc. 
     Taking the third row of data structure  1000  (e.g., associated with the sentence “Gold Coast has beautiful beaches”) as another example, the effecting portion “very beautiful” (e.g., in column  1020 ) may be associated with a sentiment of the affected portion “beaches” (e.g., in column  1010 ). A sentiment score of “+2” (e.g., as shown in column  1030 ) may be determined (e.g., in step  110 , step  120 , etc.) based on at least on attribute of the effecting portion (e.g., the word “beautiful” which may be associated with a positive sentiment or category, the word “very” modifying “beautiful” may be associated with a degree of “2,” etc.). Additionally, a classification (e.g., “Positive Description; Good Appearance” as shown in column  1040 ) associated with the affected portion (e.g., “beaches” in column  1010 ) and/or the effecting portion (e.g., “very beautiful” as shown in column  1020 ) may be determined in step  145 . In this manner, the classification data (e.g., in column  1040 ) may explain or otherwise be associated with why score data (e.g., a category, a degree, a score, other sentiment data, etc.) was determined for an affected portion (e.g., in column  1010 ) and/or an effecting portion (e.g., in column  1020 ). The classification data may also explain why a sentiment (e.g., associated with the score data in column  1030 ) of an affected portion (e.g., “beaches” in column  1010 ) was determined (e.g., in step  110 , in step  120 , etc.) to be in a certain category (e.g., positive, negative, neutral, etc.), to have a certain degree (e.g., 1, 2, 3, 4, low, medium, high, etc.), etc. 
     In one embodiment, the at least one classification (or classification data associated therewith) may be determined in step  145  by indexing a database (e.g., classification database  240 ) using an effecting portion (e.g., in column  1020 ) to obtain classification data (e.g., in column  1040 ). The indexing may be performed by classification determination component  360  of sentiment analysis component  220  in one embodiment. In this manner, the database (e.g., classification database  240 ) may include an index of portions (e.g., effecting portions such as “hit,” “beaches,” etc.) and classification data (e.g., “Negative Action Taker; Hurt,” “Negative Action Receiver; Hurt,” “Positive Description; Good Appearance,” etc.) in one embodiment. 
     As shown in  FIG. 1C , step  150  involves repeating any of the previous steps (e.g., of process  100 ) for at least one other portion of the at least one document and/or for at least one other portion of at least one other document. Step  150  may be performed by one or more components of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). In this manner, score data (e.g., including at least one category, at least one degree, at least one score, etc.), classification data associated therewith, data associated with at least one theme and/or at least one theme element, data associated with at least one semantic key and/or at least one semantic sub-key, other sentiment data, etc. may be determined and/or adjusted in step  150  for at least one other portion of the at least one document and/or for at least one other portion of at least one other document. 
     Step  155  involves storing any of the previously-accessed data (e.g., in any of the previous steps of process  100 ) in a database or index. For example, step  155  may involve storing any of the previously-accessed data in sentiment database  230  (e.g., as shown in  FIG. 2 ) in one embodiment. In one embodiment, step  155  may be performed by data storage component  370  of sentiment analysis component  220  (e.g., as shown in  FIG. 3 ). 
     In one embodiment, data stored in step  155  may be subsequently accessed and used. For example, the data stored in step  155  may be accessed and used to perform a search for at least one document, to process search results of a search for at least one document, etc. As another example, the data stored in step  155  may be accessed and used to perform at least one operation associated with search results. In one embodiment, the at least one operation may include filtering the search results, ranking the search results, displaying an image associated with the at least one sentiment (e.g., a background or other feature of a webpage which indicates a sentiment associated with a plurality of search results, a background or other feature of a particular search result which indicates a sentiment associated with the particular search result or some portion thereof, an image displayed separate from the search results which indicates a sentiment associated with one or more of the search results or some portion thereof, etc.), some combination thereof, etc. 
     Although  FIG. 2  shows a specific number and arrangement of components, it should be appreciated that  FIG. 2  may include a different number and/or arrangement of components in other embodiments. Although  FIG. 3  shows a specific number and arrangement of components, it should be appreciated that  FIG. 3  may include a different number and/or arrangement of components in other embodiments. 
     Although  FIGS. 4 through 10  depict data structures (e.g.,  400 ,  500 ,  600 A,  600 B,  600 C,  700 A,  700 B,  800 A,  800 B,  900 ,  1000 , etc.) with a certain amount and type of data, it should be appreciated that one or more of the data structures (e.g.,  400 ,  500 ,  600 A,  600 B,  600 C,  700 A,  700 B,  800 A,  800 B,  900 ,  1000 , etc.) may include a different amount and/or type of data in other embodiments. Additionally, although  FIGS. 4 through 10  depict data structures (e.g.,  400 ,  500 ,  600 A,  600 B,  600 C,  700 A,  700 B,  800 A,  800 B,  900 ,  1000 , etc.) with a certain arrangement of data, it should be appreciated that the data structures (e.g.,  400 ,  500 ,  600 A,  600 B,  600 C,  700 A,  700 B,  800 A,  800 B,  900 ,  1000 , etc.) may include a different arrangement of data in other embodiments. 
     Use of Sentiment Data 
       FIG. 11  shows a flowchart of computer-implemented process  1100  for processing data in accordance with one embodiment of the present invention.  FIG. 11  will be described in conjunction with  FIG. 13A , where  FIG. 13A  shows exemplary system  1300 A for processing data in accordance with one embodiment of the present invention. 
     As shown in  FIG. 11 , step  1110  involves accessing first data (e.g.,  1310  of  FIG. 13A ) associated with a search (e.g., to be performed by search component  1360  of  FIG. 13B ). The first data may include at least a portion of a query used for the search to generate search results (e.g.,  1365  of  FIG. 13B , at least one document  210  of  FIG. 2 , etc.), information associated with the search results (e.g., a list of identifiers of documents included in the search results, other information, etc.), at least a portion of the search results, at least one command, some combination thereof, etc. In one embodiment, the at least one command may include at least one command accessed and/or used by a sentiment component (e.g.,  1320 ) to generate and/or process sentiment data (e.g., at least one score, at least one category, at least one degree, at least one classification, etc.). For example, the at least one command may include a request for at least one document associated with at least one sentiment category (e.g., positive, negative, neutral, some combination thereof, etc.), a request for at least one document associated with at least one sentiment degree (e.g., 1, 2, 3, 4, low, medium, high, some combination thereof, etc.), a request for at least one document associated with at least one sentiment classification (e.g., an action taker, an action receiver, a description, an identity, some combination thereof, etc.), some combination thereof, etc. In one embodiment, the at least one command may include at least one command input by a user via a graphical user interface (e.g.,  1400 A of  FIG. 14A, 1400B  of  FIG. 14B, 1500  of  FIG. 15 , etc.), some combination thereof, etc. In one embodiment, the search results may include at least one document (e.g.,  210  of  FIG. 2 ) such as at least one webpage, at least one electronic document, at least one electronic file, advertising content, some combination thereof, etc. 
     In one embodiment, the first data accessed in step  1110  may include at least one theme, at least one theme element, at least one semantic key, at least one semantic sub-key, some combination thereof, etc. And in one embodiment, the first data may be accessed in step  1110  by a sentiment component (e.g.,  1320  of  FIG. 13A ). 
     As shown in  FIG. 11 , step  1120  involves accessing, using the first data (e.g., accessed in step  1110 ), other data from at least one other database (e.g., semantic key and/or theme database  1330  as shown in  FIG. 13A , another database, etc.). In one embodiment, the first data may include at least one semantic key, and the other data may include at least one semantic sub-key associated with the at least one semantic key. In one embodiment, the first data may include at least one semantic sub-key, and the other data may include at least one semantic key associated with the at least one semantic sub-key. In one embodiment, the first data may include at least one theme, and the other data may include at least one theme element associated with the at least one theme. In one embodiment, the first data may include at least one theme element, and the other data may include at least one theme associated with the at least one theme element. And in one embodiment, the other data may not be a part of (e.g., be different from) the first data and/or at least one document associated with the first data. 
     Step  1130  involves accessing, using the first data (e.g., accessed in step  1110 ) and/or the other data (e.g., accessed in step  1120 ), second data from a database (e.g., sentiment database  230  as shown in  FIG. 13A ). In one embodiment, step  1130  may involve indexing the database using the first data and/or the other data to retrieve or access the second data. The second data may include at least one score, at least one category associated with at least one sentiment, at least one degree, at least one classification, data stored in a sentiment database (e.g.,  230 , etc.), data stored in at least one data structure (e.g.,  400 ,  500 ,  600 A,  600 B,  600 C,  700 A,  700 B,  800 A,  800 B,  900 ,  1000 , etc.), some combination thereof, etc. 
     As such, in one embodiment, use of the other data (e.g., alone or in combination with the first data) to access the second data may provide one or more advantages. For example, where the other data is associated with a theme or theme element of a document, the second data (e.g., accessed in step  1130 ) may more accurately or precisely represent the sentiment of one or more portions of the document since it is accessed or determined based on a theme or theme element of the document. As another example, where the other data is associated with a semantic key (e.g., which may be a focus, concept, etc.) or semantic sub-key (e.g., which may be a word or phrase associated with the semantic key) of a query (e.g., used to generate search results including at least one document), the second data (e.g., accessed in step  1130 ) may more accurately or precisely represent the sentiment of one or more portions of the document since it is accessed or determined based on a semantic key or semantic sub-key of the query. Additionally, since the other data may not be found in the document itself in one embodiment, the quality and/or quantity of information provided by the second data may be further increased since more data (e.g., the other data in combination with the first data) may be used to determine or access the second data. 
     In one embodiment, step  1120  may be optional and omitted. In this case, step  1130  may involve accessing the second data using the first data (e.g., and not the other data). 
     As shown in  FIG. 11 , step  1140  involves generating third data (e.g., sentiment data  1340  of  FIG. 13A ) for performing at least one operation (e.g., as described with respect to step  1240  of process  1200  of  FIG. 12 ) associated with search results (e.g., including at least one document) of the search. In one embodiment, the third data may be generated in step  1140  based on the first data (e.g., accessed in step  1110 ), the other data (e.g., accessed in step  1120 ), the second data (e.g., accessed in step  1130 ), some combination thereof, etc. 
       FIG. 12  shows a flowchart of computer-implemented process  1200  for performing at least one operation in accordance with one embodiment of the present invention.  FIG. 12  will be described in conjunction with  FIG. 13B , where  FIG. 13B  shows exemplary system  1300 B for performing at least one operation in accordance with one embodiment of the present invention. 
     As shown in  FIG. 12 , step  1210  involves accessing a query (e.g.,  1350 ). The query may be included in or include data associated with a search (e.g.,  1310  of  FIG. 13A ). The query may include at least one word, at least one phrase, at least one name, semantic data, score data, classification data, a portion of data (e.g., an effecting portion; an affected portion; a portion of data similar to the first portion, second portion, third portion, fourth portion, etc. as discussed with respect to process  100 ; etc.), some combination thereof, etc. The query may be accessed in step  1210  by a search component (e.g.,  1360 ). An in one embodiment, the query accessed in step  1210  may be input using a region (e.g.,  1411 ,  1431 ,  1510 , some combination thereof, etc.) of a graphical user interface (e.g.,  1400 A,  1400 B,  1500 , some combination thereof, etc.). 
     Step  1220  involves performing a search using the query (e.g., accessed in step  1210 ). The search may be performed (e.g., by search component  1360 ), in one embodiment, using search index  1370 . For example, the query or a portion thereof may be used to index the search index (e.g.,  1370 ) to access at least one document or data associated therewith. Step  1220  may involve generating search results (e.g.,  1365 ) that include one or more documents. 
     Search index  1370  may be a keyword search index (e.g., used to perform a keyword search) in one embodiment. In one embodiment, search index  1370  may include information associated with a theme (e.g., at least one theme, at least one theme element, etc.), where the information may be used to perform a search based on at least one theme and/or at least one theme element. Search index  1370  may include information associated with a semantic key (e.g., at least one semantic key, at least one semantic sub-key, etc.) in one embodiment, where the information may be used to perform a search based on at least one semantic key and/or at least one semantic sub-key. 
     As shown in  FIG. 12 , step  1230  involves accessing search results associated with the search. The search results (e.g.,  1365 ) may include at least one document (e.g.,  210  of  FIG. 2 , etc.) or data associated therewith. The search results may be generated and/or output by a search component (e.g.,  1360  in step  1220 ). 
     Step  1240  involves accessing sentiment data associated with the search (e.g., performed in step  1220 ). In one embodiment, the sentiment data accessed in step  1240  may be generated in accordance with one or more steps of process  1100  of  FIG. 11 . As such, the sentiment data may be the “third data” generated in step  1140  in one embodiment, and therefore, may be determined or generated based on the “first data associated with a search” (e.g., a query used for the search to generate search results, information associated with the search results, at least a portion of the search results, at least one command, etc.) as accessed in step  1110 . 
     In one embodiment, the sentiment data accessed in step  1240  may be associated with or determined based on the search query (e.g.,  1350  accessed in step  1210 ). For example, the query (e.g.,  1310 ) may be provided to a sentiment component (e.g.,  1320  as part of data associated with a search  1310 ), and therefore, the sentiment data (e.g.,  1340 ) may be generated by the sentiment component (e.g.,  1320 ) based on the query (e.g.,  1310 ) in one embodiment. As a more specific example, the sentiment data (e.g.,  1340 ) may include sentiment data (e.g., at least one score, at least one category, at least one degree, at least one classification, etc.) associated with one or more portions (e.g., including at least one word, at least one phrase, etc.) of the search query, one or more themes associated with the search query (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more theme elements associated with the search query (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more semantic keys associated with the search query (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more semantic sub-keys associated with the search query (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), etc. 
     In one embodiment, the sentiment data accessed in step  1240  may be associated with or determined based on at least a portion of the search results (e.g.,  1365  accessed in step  1230 ) and/or information associated with search results (e.g., a list of identifiers of documents included in the search results, other information, etc.). For example, at least a portion of the search results (e.g.,  1365 ) and/or information associated with search results may be provided to a sentiment component (e.g.,  1320  as part of data associated with a search  1310 ), and therefore, the sentiment data (e.g.,  1340 ) may be generated by the sentiment component (e.g.,  1320 ) based on the search results (e.g.,  1365 ) and/or information associated with search results in one embodiment. As a more specific example, the sentiment data (e.g.,  1340 ) may include sentiment data (e.g., at least one score, at least one category, at least one degree, at least one classification, etc.) associated with at least one portion of the search results and/or information associated therewith, one or more themes associated with at least one portion of the search results and/or information associated therewith (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more theme elements associated with at least one portion of the search results and/or information associated therewith (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more semantic keys associated with at least one portion of the search results and/or information associated therewith (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more semantic sub-keys associated with at least one portion of the search results and/or information associated therewith (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), etc. 
     In one embodiment, the sentiment data accessed in step  1240  may be associated with or determined based on at least one command (e.g., a request for at least one document associated with at least one sentiment category; a request for at least one document associated with at least one sentiment degree; a request for at least one document associated with at least one sentiment classification; at least one command input by a user via a graphical user interface such as graphical user interface  1400 A of  FIG. 14A , graphical user interface  1400 B of  FIG. 14B  and/or graphical user interface  1500  of  FIG. 15 ; some combination thereof; etc.). For example, the at least one command may be provided to a sentiment component (e.g.,  1320  as part of data associated with a search  1310 ), and therefore, the sentiment data (e.g.,  1340 ) may be generated by the sentiment component (e.g.,  1320 ) based on the at least one command in one embodiment. As a more specific example, the sentiment data (e.g.,  1340 ) may include sentiment data (e.g., at least one score, at least one category, at least one degree, at least one classification, etc.) associated with the at least one command, one or more themes associated with the at least one command (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more theme elements associated with the at least one command (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more semantic keys associated with the at least one command (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), one or more semantic sub-keys associated with the at least one command (e.g., as determined by sentiment component  1320  using data accessed from database  1330  as shown in  FIG. 13A , as determined by search component  1360  using data accessed from database  1330  as shown in  FIG. 13B , some combination thereof, etc.), etc. 
       FIG. 14A  shows exemplary on-screen graphical user interface (GUI)  1400 A for accessing data associated with a search (e.g.,  1310 ) in accordance with one embodiment of the present invention. As shown in  FIG. 14A , regions  1410  may allow entry of data associated with a search (e.g.,  1310 ), where the data associated with the search may include at least a portion of at least one query (e.g.,  1350 ), at least one command (e.g., a request for at least one document associated with at least one sentiment category, a request for at least one document associated with at least one sentiment degree, a request for at least one document associated with at least one sentiment classification, some combination thereof, etc.), some combination thereof, etc. Region  1420  may be used to execute or perform a search based on data entered using region  1410 . 
     In one embodiment, a query may be entered (e.g., using region  1411 ) without any commands associated with sentiment. For example, if the text “Toyota Land Cruiser performance” is entered into either region  1411 , a search (e.g., a keyword search, a search based on at least one theme and/or at least one theme element, a search based on at least one semantic key and/or at least one semantic sub-key, some combination thereof, etc.) may be performed to generate search results including at least one document including the words or phrases “Toyota Land Cruiser” and “performance” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser” and/or “performance,” at least one theme element associated with “Toyota Land Cruiser” and/or “performance,” at least one semantic key associated with “Toyota Land Cruiser” and/or “performance,” at least one semantic sub-key associated with “Toyota Land Cruiser” and/or “performance,” some combination thereof, etc.). 
     In one embodiment, region  1410  may be used to enter or input a query and at least one command associated with any category of sentiment (e.g., positive, negative, neutral, some combination thereof, etc.). For example, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) and at least one command associated with any category of sentiment by separating the at least one command and the query by a colon or other symbol (e.g., entering the text “sentiment: Toyota Land Cruiser” into region  1411 ). Alternatively, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) while region  1412  may be used to enter or select at least one command associated with any category of sentiment. In either case, sentiment data (e.g.,  1340 ) may be accessed (e.g., in step  1240 ) based on at least a portion of the query and/or the at least one command. The sentiment data may be associated with or include at least one sentiment (e.g., associated with at least one category of positive, negative, neutral or some combination thereof as selected or indicated using region  1411  and/or region  1412 ) of the Toyota Land Cruiser. As such, the sentiment data may be used to perform (e.g., in step  1250  as discussed herein) at least one operation (e.g., filtering, ranking, generating data for displaying an image, displaying an image, some combination thereof, etc.) associated with search results (e.g., accessed in step  1230 , generated responsive to an interaction with region  1420 , etc.). In one embodiment, the search results (e.g., processed search results  1375  of  FIG. 13B ) may include at least one document including at least one affected portion (e.g., associated with any category of sentiment as selected or indicated using region  1411  and/or region  1412 ), where the at least one affected portion may include the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.). As such, the search may provide search results associated with any category of sentiment (e.g., selected or indicated using region  1411  and/or region  1412 ) of the Toyota Land Cruiser. 
     In one embodiment, region  1410  may be used to enter or input a query and at least one command associated with at least one particular category of sentiment (e.g., positive, negative, neutral, some combination thereof, etc.). For example, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) and at least one command associated with at least one particular category of sentiment (e.g., the word “positive” or the like to request results associated with a positive sentiment, the word “negative” or the like to request results associated with a negative sentiment, the word “neutral” or the like to request results associated with a neutral sentiment, some combination thereof, etc.) by separating the at least one command and the query by a colon or other symbol (e.g., entering the text “positive: Toyota Land Cruiser” into region  1411 , entering the text “negative: Toyota Land Cruiser” into region  1411 , entering the text “neutral: Toyota Land Cruiser” into region  1411 , etc.). Alternatively, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) while at least one other region (e.g.,  1413 ,  1414 ,  1415 , some combination thereof, etc.) may be used to enter or select at least one command associated with at least one particular category of sentiment (e.g., positive, negative, neutral, some combination thereof, etc.). In either case, sentiment data (e.g.,  1340 ) may be accessed (e.g., in step  1240 ) based on at least a portion of the query and/or the at least one command. The sentiment data may be associated with or include at least one sentiment (e.g., associated with at least one category of positive, negative, neutral or some combination thereof as selected or indicated using region  1411 , region  1413 , region  1414 , region  1415 , some combination thereof, etc.) of the Toyota Land Cruiser. As such, the sentiment data may be used to perform (e.g., in step  1250  as discussed herein) at least one operation (e.g., filtering, ranking, generating data for displaying an image, displaying an image, some combination thereof, etc.) associated with search results (e.g., accessed in step  1230 , generated responsive to an interaction with region  1420 , etc.). In one embodiment, the search results (e.g., processed search results  1375  of  FIG. 13B ) may include at least one document including at least one affected portion (e.g., associated with at least one particular category of sentiment selected or indicated using region  1411 , region  1413 , region  1414 , region  1415 , some combination thereof, etc.), where the at least one affected portion may include the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.). As such, the search may provide search results associated with at least one particular category of sentiment (e.g., selected or indicated using region  1411 , region  1413 , region  1414 , region  1415 , some combination thereof, etc.) of the Toyota Land Cruiser. 
     In one embodiment, region  1410  may be used to enter or input a query and at least one command associated with at least one particular degree of sentiment (e.g., 1, 2, 3, 4, low, medium, high, etc.). For example, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) and at least one command associated with at least one particular degree of sentiment (e.g., the word “low” or the like to request results associated with a low degree of sentiment, the word “medium” or the like to request results associated with a medium degree of sentiment, the word “high” or the like to request results associated with a high degree of sentiment, some combination thereof, etc.) by separating the at least one command and the query by a colon or other symbol (e.g., entering the text “low: Toyota Land Cruiser” into region  1411 , entering the text “medium: Toyota Land Cruiser” into region  1411 , entering the text “high: Toyota Land Cruiser” into region  1411 , etc.). Alternatively, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) while another region (e.g.,  1416 ) may be used to enter or select at least one command associated with at least one particular degree of sentiment (e.g., 1, 2, 3, 4, low, medium, high, some combination thereof, etc.). In either case, sentiment data (e.g.,  1340 ) may be accessed (e.g., in step  1240 ) based on at least a portion of the query and/or the at least one command. The sentiment data may be associated with or include at least one sentiment (e.g., associated with at least one degree of 1, 2, 3, 4, low, medium, high, or some combination thereof as selected or indicated using region  1411  and/or region  1416 ) of the Toyota Land Cruiser. As such, the sentiment data may be used to perform (e.g., in step  1250  as discussed herein) at least one operation (e.g., filtering, ranking, generating data for displaying an image, displaying an image, some combination thereof, etc.) associated with search results (e.g., accessed in step  1230 , generated responsive to an interaction with region  1420 , etc.). In one embodiment, the search results (e.g., processed search results  1375  of  FIG. 13B ) may include at least one document including at least one affected portion (e.g., associated with at least one particular degree of sentiment selected or indicated using region  1411  and/or region  1416 ), where the at least one affected portion may include the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.). As such, the search may provide search results associated with at least one particular degree of sentiment (e.g., selected or indicated using region  1411  and/or region  1416 ) of the Toyota Land Cruiser. 
     In one embodiment, region  1410  may be used to enter or input a query and at least one command associated with at least one particular classification of sentiment (e.g., an action taker, an action receiver, a description, an identity, some combination thereof, etc.). For example, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) and at least one command associated with at least one particular classification of sentiment (e.g., the words “action taker” or the like to request results associated with a sentiment classification of “action taker,” the words “action receiver” or the like to request results associated with a sentiment classification of “action receiver,” the word “description” or the like to request results associated with a sentiment classification of “description,” the word “identity” or the like to request results associated with a sentiment classification of “identity,” some combination thereof, etc.) by separating the at least one command and the query by a colon or other symbol (e.g., entering the text “action taker: Toyota Land Cruiser” into region  1411 , entering the text “action receiver: Toyota Land Cruiser” into region  1411 , entering the text “description: Toyota Land Cruiser” into region  1411 , entering the text “identity: Toyota Land Cruiser” into region  1411 , etc.). Alternatively, region  1411  may be used to enter a query (e.g., “Toyota Land Cruiser”) while another region (e.g.,  1417 ) may be used to enter or select at least one command associated with at least one particular classification of sentiment (e.g., an action taker, an action receiver, a description, an identity, some combination thereof, etc.). In either case, sentiment data (e.g.,  1340 ) may be accessed (e.g., in step  1240 ) based on at least a portion of the query and/or the at least one command. The sentiment data may be associated with or include at least one sentiment (e.g., associated with at least one classification of action taker, action receiver, description, identity, some combination thereof, etc. as selected or indicated using region  1411  and/or region  1417 ) of the Toyota Land Cruiser. As such, the sentiment data may be used to perform (e.g., in step  1250  as discussed herein) at least one operation (e.g., filtering, ranking, generating data for displaying an image, displaying an image, some combination thereof, etc.) associated with search results (e.g., accessed in step  1230 , generated responsive to an interaction with region  1420 , etc.). In one embodiment, the search results (e.g., processed search results  1375  of  FIG. 13B ) may include at least one document including at least one affected portion (e.g., associated with at least one particular classification of sentiment selected or indicated using region  1411  and/or region  1417 ), where the at least one affected portion may include the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.). As such, the search may provide search results associated with at least one particular classification of sentiment (e.g., selected or indicated using region  1411  and/or region  1417 ) of the Toyota Land Cruiser. 
     Region  1410  may be used to enter or input a plurality of commands. For example, at least one command associated with a category of sentiment may be input (e.g., using region  1411 , region  1412 , region  1413 , region  1414 , region  1415 , some combination thereof, etc.) in conjunction with at least one command associated with a degree of sentiment (e.g., input using region  1416 ) and/or at least one command associated with a classification of sentiment (e.g., input using region  1417 ). As another example, at least one command associated with a degree of sentiment may be input (e.g., using region  1416 ) in conjunction with at least one command associated with a category of sentiment (e.g., input using region  1411 , region  1412 , region  1413 , region  1414 , region  1415 , some combination thereof, etc.) and/or at least one command associated with a classification of sentiment (e.g., input using region  1417 ). As yet another example, at least one command associated with a classification of sentiment may be input (e.g., using region  1417 ) in conjunction with at least one command associated with a degree of sentiment (e.g., input using region  1416 ) and/or at least one command associated with a category of sentiment (e.g., input using region  1411 , region  1412 , region  1413 , region  1414 , region  1415 , some combination thereof, etc.). 
     The plurality of commands may cause a filtering of the sentiment data or a return of less sentiment data in one embodiment. For example, where commands for a specific category of sentiment and a specific degree of sentiment are input, sentiment data returned responsive thereto may include sentiment data associated with the specific category and also with the specific degree. As such, in one embodiment, the sentiment data (e.g., accessed in step  1240 ) may be free of or not include at least one portion (e.g., that is not associated with all of the commands input or accessed) as a result of the plurality of commands. 
     In one embodiment, region  1411  may be used to input the plurality of commands. For example, the text “positive medium description: Toyota Land Cruiser” (e.g., entered into region  1411 ) may be used to input the command “positive” (e.g., a request for at least one document associated with positive sentiment of the Toyota Land Cruiser), the command “medium” (e.g., a request for at least one document associated with a medium degree of sentiment of the Toyota Land Cruiser), and the command “description” (e.g., a request for at least one document associated with sentiment of the Toyota Land Cruiser that can be classified as a description or the like). Alternatively, the plurality of commands may be input using region  1411  in combination with at least one other region (e.g.,  1412 ,  1413 ,  1414 ,  1415 ,  1416 ,  1417 , some combination thereof, etc.). 
     Region  1410  may be used to input at least one command associated with one portion of a query and not with another in one embodiment. For example, the text “positive: Toyota Land Cruiser, performance” may be entered into region  1411 , where the command “positive” may be associated with the query portion “Toyota Land Cruiser” and not associated with the query portion “performance.” 
     Based on the text entered into region  1411 , a search (e.g., a keyword search, a search based on at least one theme and/or at least one theme element, a search based on at least one semantic key and/or at least one semantic sub-key, some combination thereof, etc.) may be performed (responsive to an interaction with region  1420 ) to generate search results including at least one document including: at least one affected portion (e.g., associated with a positive category of sentiment) including the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.); and the word “performance” or other data associated therewith (e.g., at least one theme associated with “performance,” at least one theme element associated with “performance,” at least one semantic key associated with “performance,” at least one semantic sub-key associated with “performance,” some combination thereof, etc.). As such, region  1410  may be used to limit search results associated with sentiment data, use sentiment data to limit keyword search results or other types of search results, provide more relevant search results, etc. 
     In one embodiment, region  1410  may be used to input a plurality of commands associated with a plurality of portions of a query. For example, the text “neutral: Toyota Land Cruiser, positive: performance” may be entered into region  1411 , where the command “neutral” may be associated with the query portion “Toyota Land Cruiser” and the command “positive” may be associated with the query portion “performance.” Based on the text entered into region  1411 , a search (e.g., a keyword search, a search based on at least one theme and/or at least one theme element, a search based on at least one semantic key and/or at least one semantic sub-key, some combination thereof, etc.) may be performed (responsive to an interaction with region  1420 ) to generate search results including at least one document including: at least one affected portion (e.g., associated with a neutral category of sentiment) including the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.); and at least one affected portion (e.g., associated with a positive category of sentiment) including the words or phrase “performance” or other data associated therewith (e.g., at least one theme associated with “performance,” at least one theme element associated with “performance,” at least one semantic key associated with “performance,” at least one semantic sub-key associated with “performance,” some combination thereof, etc.). 
       FIG. 14B  shows exemplary on-screen graphical user interface (GUI)  1400 B for accessing at least one portion of data associated with a search (e.g.,  1310 ) in accordance with one embodiment of the present invention. A shown in  FIG. 14B , GUI  1400 B may include regions  1410 ,  1420  and  1430 . Region  1430  may operate similarly to or identically to region  1410  in one embodiment. For example, region  1431  may correspond to region  1411 , region  1432  may correspond to region  1412 , region  1433  may correspond to region  1413 , region  1434  may correspond to region  1414 , region  1435  may correspond to region  1415 , region  1436  may correspond to region  1416 , region  1437  may correspond to region  1417 , etc. In this manner, GUI  1400 B may be used to input a first portion of data (e.g., including a query and/or at least one command) and a second portion of data (e.g., including at least one other query and/or at least one other command), where the first and second portions of data may be used to access sentiment data (e.g., in step  1240 ) and/or perform at least one operation associated with search results (e.g., in step  1250 ). 
     The first and second portions of data (e.g., input using regions  1410  and  1430 , respectively) may be used to implement a Boolean function (e.g., and “AND” function) in one embodiment. For example, if region  1410  is used to enter the query portion “Toyota Land Cruiser” and the command “positive” (e.g., using region  1411 , using region  1413 , etc.) while region  1430  is used to enter the query portion “performance,” then a search (e.g., a keyword search, a search based on at least one theme and/or at least one theme element, a search based on at least one semantic key and/or at least one semantic sub-key, some combination thereof, etc.) may be performed (responsive to an interaction with region  1420 ) to generate search results including at least one document including: at least one affected portion (e.g., associated with a positive category of sentiment) including the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.); and the word “performance” or other data associated therewith (e.g., at least one theme associated with “performance,” at least one theme element associated with “performance,” at least one semantic key associated with “performance,” at least one semantic sub-key associated with “performance,” some combination thereof, etc.). As another example, if region  1410  is used to enter the query portion “Toyota Land Cruiser” and the command “neutral” (e.g., using region  1411 , using region  1415 , etc.) while region  1430  is used to enter the query portion “performance” and the command “positive” (e.g., using region  1431 , using region  1433 , etc.), then a search (e.g., a keyword search, a search based on at least one theme and/or at least one theme element, a search based on at least one semantic key and/or at least one semantic sub-key, some combination thereof, etc.) may be performed (responsive to an interaction with region  1420 ) to generate search results including at least one document including: at least one affected portion (e.g., associated with a neutral category of sentiment) including the words or phrase “Toyota Land Cruiser” or other data associated therewith (e.g., at least one theme associated with “Toyota Land Cruiser,” at least one theme element associated with “Toyota Land Cruiser,” at least one semantic key associated with “Toyota Land Cruiser,” at least one semantic sub-key associated with “Toyota Land Cruiser,” some combination thereof, etc.); and at least one affected portion (e.g., associated with a positive category of sentiment) including the words or phrase “performance” or other data associated therewith (e.g., at least one theme associated with “performance,” at least one theme element associated with “performance,” at least one semantic key associated with “performance,” at least one semantic sub-key associated with “performance,” some combination thereof, etc.). 
       FIG. 15  shows exemplary on-screen graphical user interface (GUI)  1500  for automatically suggesting at least one command in accordance with one embodiment of the present invention. As shown in  FIG. 15 , at least one command (e.g., “sentiment”) may be automatically suggested using region  1520 . The at least one command may be identified by one or more elements (e.g., dashed line  1522 , colored or grayed background  1524 , some combination thereof, etc.). The at least one command may be automatically suggested based on text (e.g., the letters “sen”) entered in region  1510  in one embodiment. And in one embodiment, element  1526  (e.g., a slider, scroll bar, etc.) may be used to scroll through and/or select one or more items listed in region  1520  (e.g., including the command “sentiment,” other than the command “sentiment,” etc.). 
     Accordingly, embodiments enable more efficient selection and entry of at least one command. Additionally, embodiments allow users to determine and/or select commands without prior knowledge of the commands. For example, where a user is not aware that the word “sentiment” is a command, region  1520  may display the command “sentiment” (and/or one or more other commands related thereto such as positive, negative, neutral, etc.) responsive to entry of one or more letters in region  1510  (e.g., the letter “s,” the letters “se,” the letters “sen,” etc.). As such, region  1520  may be used to inform a user of one or more possible commands for selection and/or use. 
     As shown in  FIGS. 14A, 14B and 15 , each region (e.g., of GUI  1400 A,  1400 B,  1500 , some combination thereof, etc.) may include one or more respective form fields. Each form field may be or include at least one text entry box, at least one drop-down list box, at least one radio button, at least one checkbox, etc. 
     Although  FIGS. 14A, 14B and 15  show GUIs (e.g.,  1400 A,  1400 B and  1500 , respectively) with a specific number and arrangement of elements, it should be appreciated that the GUIs (e.g.,  1400 A,  1400 B and  1500 ) may include a different number and arrangement of elements in other embodiments. For example, a GUI (e.g.,  1400 A,  1400 B,  1500 , etc.) may include more than three regions similar to region  1410  and/or region  1430 . As another example, one or more regions of a GUI (e.g.,  1400 A,  1400 B,  1500 , etc.) may include a different number of sub-regions. 
     Additionally, although  FIGS. 14A, 14B and 15  show GUIs (e.g.,  1400 A,  1400 B and  1500 , respectively) with specific functionality, it should be appreciated that the GUIs (e.g.,  1400 A,  1400 B and  1500 ) may include elements with different or additional functionality in other embodiments. For example, at least one region (e.g.,  1416 ,  1417 ,  1426 ,  1427 , etc.) may be implemented using another type of form field (e.g., at least one radio button, at least one checkbox, etc.). 
     Further, although the GUIs (e.g.,  1400 A,  1400 B,  1500 , etc.) have been discussed with respect to one or more specific configurations of the query and/or command, it should be appreciated that the configuration of the query and/or command may be different in other embodiments. For example, the query and command may be entered (e.g., into region  1411 , into region  1431 , etc.) in a different order (e.g., query before at least one command, etc.), separated by a different symbol (e.g., other than a colon, etc.), consecutively (e.g., region  1411  and/or region  1431  may be cleared after entry of the at least one command to allow entry of the query, region  1411  and/or region  1431  may be cleared after entry of the query to allow entry of the at least one command, etc.), some combination thereof, etc. And further yet, it should be appreciated that the commands may be alternatively expressed (e.g., using different words, using different phrases, using different text, using a symbol such as “+” instead of a word such as “positive,” etc.) in other embodiments. 
     Turning back to  FIG. 12 , step  1250  involves performing, using the sentiment data (e.g., accessed in step  1240 ), at least one operation associated with the search results (e.g., accessed in step  1230 ). In one embodiment, step  1250  may involve processing (e.g., using search result processing component  1380 ) the search results (e.g.,  1365 ) based on the sentiment data (e.g.,  1340 ) to generate processed search results (e.g.,  1375 ). The processing may involve filtering the search results (e.g., removing at least one search result or data associated therewith from the search results) based on the sentiment data (e.g., accessed in step  1240 ), ranking the search results (e.g., reordering the search results or data associated therewith) based on the sentiment data (e.g., accessed in step  1240 ), some combination thereof, etc. For example, one or more search results (or data associated therewith) that are not associated with the sentiment data (e.g., accessed in step  1240 ) may be removed from the search results in step  1250 . As another example, the search results (or data associated therewith) may be ordered based on a respective score, a respective category of sentiment, a respective degree of sentiment, a respective classification of sentiment, etc. 
     In one embodiment, step  1250  may involve generating data for displaying an image associated with the sentiment data (e.g., accessed in step  1240 ) and/or displaying the image. The data generated in step  1250  may include pixel data, texture data, at least one frame, at least one image, some combination thereof, etc. In one embodiment, display component  1390  may be used to generate data for displaying the image (e.g., associated with sentiment data  1340 ) and/or used to display the image in step  1250 . In one embodiment, the data for displaying the image may be generated (e.g., by display component  1390 ) based on search results  1365  and/or processed search results  1375  (e.g., as shown in  FIG. 13B ). And in one embodiment, search results  1365  and/or processed search results  1375  may be directly displayed using display component  1390 . 
     The image associated with the sentiment data (e.g.,  1340 ) may include a background (e.g., region  1640  of GUI  1600 B of  FIG. 16B , region  1690  of GUI  1600 C of  FIG. 16C , etc.) of a webpage associated with the search results, a background (e.g., region  1651  of GUI  1600 B of  FIG. 16B , region  1652  of GUI  1600 B of  FIG. 16B , region  1653  of GUI  1600 B of  FIG. 16B , region  1654  of GUI  1600 B of  FIG. 16B , etc.) of a webpage associated with at least one search result, at least one icon (e.g.,  1652  of  FIG. 16B, 1662  of  FIG. 16B, 1672  of  FIG. 16B, 1682  of  FIG. 16B, 1684  of  FIG. 16B , etc.) associated with at least one search result, formatting (e.g., highlighting, bolding, underlining, italicizing, making larger, making smaller, superscripting, subscripting, changing the color of, capitalization, alternatively formatting, etc.) of text associated with at least one search result, some combination thereof, etc. 
       FIG. 16A  shows exemplary on-screen graphical user interface (GUI)  1600 A associated with at least one search result in accordance with one embodiment of the present invention. As shown in  FIG. 16A , GUI  1600 A may include at least one region (e.g.,  1610 ,  1620 ,  1630 , etc.). In one embodiment, GUI  1600 A may be used to implement or be displayed as at least a portion of a webpage. 
     In one embodiment, region  1610  may include at least one element (e.g., of GUI  1400 A of  FIG. 14A , of GUI  1400 B of  FIG. 14B , of GUI  1500  of  FIG. 15 , etc.) for accessing data associated with a search (e.g.,  1310 , in accordance with step  1110 , etc.). For example, region  1610  may include at least one form field allowing the entry or input of at least one query and/or at least one command. Region  1610  may include at least one element (e.g., of GUI  1400 A of  FIG. 14A , of GUI  1400 B of  FIG. 14B , of GUI  1500  of  FIG. 15 , etc.) allowing a search for at least one document (e.g., performed in accordance with step  1220 ) to be initiated in one embodiment. For example, region  1610  may include at least one element (e.g., similar to region  1420  of  FIG. 14A  and/or  FIG. 14B ) allowing the initiation of a search for at least one document. And in one embodiment, region  1610  may be implemented by at least one GUI (e.g.,  1400 A of  FIG. 14A, 1400B  of  FIG. 14B, 1500  of  FIG. 15 , another GUI, etc.). 
     As shown in  FIG. 16 , region  1620  may include at least one search result and/or data associated therewith. For example, region  1620  may include at least one respective identifier associated with each search result. As another example, region  1620  may include at least one respective snippet or portion of text associated with each search result. As yet another example, region  1620  may include at least one respective portion of sentiment data (e.g., at least one score, at least one category, at least one degree, at least one classification, some combination thereof, etc.) associated with each search result. And in one embodiment, region  1620  may be implemented by at least one GUI (e.g.,  1600 B of  FIG. 16B , another GUI, etc.). 
       FIG. 16B  shows exemplary on-screen graphical user interface (GUI)  1600 B for displaying at least one search result in accordance with one embodiment of the present invention. In one embodiment, GUI  1600 B may be used to implement or be displayed in region  1630  of GUI  1600 A of  FIG. 16A . And in one embodiment, GUI  1600 B may be used to implement or be displayed as at least a portion of a webpage. 
     As shown in  FIG. 16B , GUI  1600  may include at least one respective region (e.g.,  1650 ,  1660 ,  1670 ,  1680 , etc.) for displaying information associated with each search result of at least one search result. The information may include at least one respective identifier associated with each search result (e.g., “Document  1 ,” “Document  2 ,” “Document  3 ,” “Document  4 ,” etc.), at least one respective snippet or portion of text associated with each search result (e.g., “The steering of the Toyota Land Cruiser is very good,” “However, the fuel economy is bad,” “The engine of the Toyota Land Cruiser is very good,” etc.), some combination thereof, etc. Display of the snippets or portions of text of the search results or documents may function as a preview of a search result or document (e.g., allowing a user to view a portion of a document without having to access or download the entire document). 
     GUI  1600 B may also include an image or information associated with sentiment data (e.g., associated with a particular search result, associated with a plurality of search results, etc.). In one embodiment, a respective image may be displayed as a respective background of at least one region of GUI  1600 B (e.g., within region  1650 , within region  1660 , within region  1670 , within region  1680 , etc.), where the respective images may be associated with respective sentiment data of each search result. For example, a green image may be displayed as the background of region  1650  to indicate a positive sentiment score (e.g., a combined sentiment score determined based on respective sentiment scores associated with a plurality of affected portions, a single sentiment score where at least one document only includes a single respective affected portion, etc.) of “+1” associated with “Document  1 ,” a red image may be displayed as the background of region  1670  to indicate a negative sentiment score (e.g., a combined sentiment score determined based on respective sentiment scores associated with a plurality of affected portions, a single sentiment score where at least one document only includes a single respective affected portion, etc.) of “−1” associated with “Document  3 ,” a white image may be displayed as the background of region  1650  to indicate a neutral sentiment score (e.g., a combined sentiment score determined based on respective sentiment scores associated with a plurality of affected portions, a single sentiment score where at least one document only includes a single respective affected portion, etc.), etc. The image may be a solid color or shade of gray, a color or shade of gray that is at least partially translucent (e.g., to all the contemporaneous viewing of overlapping text or other images), a pattern, a pixilated image include a plurality of pixels, some combination thereof, etc. In this manner, GUI  1600 B may communicate and/or provide a relatively large amount of data in a comprehensible and intuitive manner, thereby allowing the respective sentiment of each search result to be quickly and easily determined and/or identified by a viewer or user of GUI  1600 B in one embodiment. 
     Each image displayed in each region (e.g.,  1650 ,  1660 ,  1670 ,  1680 , etc.) may be determined based on at least one score and/or at least one category associated with each search result (e.g., from one or more columns of data structure  500 ). For example, an image associated with a positive sentiment may be displayed if: a positive score (e.g., in column  520 ) is larger than at least one other score (e.g., in column  530 , in column  540 , etc.) for a given search result or document; and/or a net score (e.g., in column  550 ) is positive. As another example, an image associated with a negative sentiment may be displayed if: a negative score (e.g., in column  530 ) is larger than at least one other score (e.g., in column  520 , in column  540 , etc.) for a given search result or document; and/or a net score (e.g., in column  550 ) is negative. As a further example, an image associated with a neutral sentiment may be displayed if: a neutral score (e.g., in column  540 ) is larger than at least one other score (e.g., in column  520 , in column  530 , etc.) for a given search result or document; and/or a net score (e.g., in column  550 ) is neutral (e.g., zero, within a predetermined positive range from zero, within a predetermined negative range from zero, etc.). 
     Each image displayed in each region (e.g.,  1650 ,  1660 ,  1670 ,  1680 , etc.) may be determined based on at least one score and/or at least one degree associated with each search result (e.g., from one or more columns of data structure  500 ). For example, an image associated with a low degree may be displayed if the absolute value of a score (e.g., in one or more columns of data structure  500 ) is below a predetermined threshold. As another example, an image associated with a medium degree may be displayed if the absolute value of a score (e.g., in one or more columns of data structure  500 ) is below a first predetermined threshold and/or above a second predetermined threshold. As a further example, an image associated with a high degree may be displayed if the absolute value of a score (e.g., in one or more columns of data structure  500 ) is above a predetermined threshold. 
     Each image displayed in each region (e.g.,  1650 ,  1660 ,  1670 ,  1680 , etc.) may be determined based on at least one classification associated with each search result (e.g., from column  1040  of data structure  1000 ). For example, a first image associated with a first classification may be displayed for any search results associated with the first classification, a second image associated with a second classification may be displayed for any search results associated with the second classification, etc. 
     In one embodiment, an image associated with sentiment data may be displayed as a background of GUI  1600 B (e.g., within region  1640 ), where the image may be associated with sentiment data of a plurality of search results (e.g., associated with region  1650 , region  1660 , region  1670 , region  1680 , etc.). For example, a green image may be displayed as the background of region  1640  to indicate a positive sentiment score (e.g., a combined sentiment score determined based on respective sentiment scores associated with each of the search results) of the search results (e.g., where the respective sentiment scores add to make a positive sentiment score for the search results), a red image may be displayed as the background of region  1640  to indicate a negative sentiment score (e.g., a combined sentiment score determined based on respective sentiment scores associated with each of the search results) of the search results (e.g., where the respective sentiment scores add to make a negative sentiment score for the search results), a white image may be displayed as the background of region  1640  to indicate a neutral sentiment score (e.g., a combined sentiment score determined based on respective sentiment scores associated with each of the search results) of the search results (e.g., where the respective sentiment scores add to make a sentiment score of zero for the search results, a score of within a predetermined range for the search results, etc.), etc. The image may be a solid color or shade of gray, a color or shade of gray that is at least partially translucent (e.g., to all the contemporaneous viewing of overlapping text or other images), a pattern, a pixilated image include a plurality of pixels, some combination thereof, etc. In this manner, GUI  1600 B may communicate and/or provide a relatively large amount of data in a comprehensible and intuitive manner, thereby allowing the respective sentiment of each search result to be quickly and easily determined and/or identified by a viewer or user of GUI  1600 B in one embodiment. 
     Each image displayed in region  1640  may be determined based on at least one score and/or at least one category associated with the search results (e.g., from one or more columns of data structure  500 ). For example, an image associated with a positive sentiment may be displayed if: a sum of the positive scores for the search results or documents (e.g., in column  520 ) is larger than at least one other score (e.g., in column  530 , in column  540 , etc.) for the search results or documents; and/or a sum of the net scores for the search results or documents (e.g., in column  550 ) is positive. As another example, an image associated with a negative sentiment may be displayed if: a sum of the negative scores for the search results or documents (e.g., in column  530 ) is larger than at least one other score (e.g., in column  520 , in column  540 , etc.) for the search results or documents; and/or a sum of the net scores for the search results or documents (e.g., in column  550 ) is negative. As a further example, an image associated with a neutral sentiment may be displayed if: a sum of the neutral scores for the search results or documents (e.g., in column  540 ) is larger than at least one other score (e.g., in column  520 , in column  530 , etc.) for the search results or documents; and/or a sum of the net scores for the search results or documents (e.g., in column  550 ) is neutral (e.g., zero, within a predetermined positive range from zero, within a predetermined negative range from zero, etc.). 
     Each image displayed in region  1640  may be determined based on at least one score and/or at least one degree associated with each search result (e.g., from one or more columns of data structure  500 ). For example, an image associated with a low degree may be displayed if the absolute value of a sum of the scores for the search results or documents (e.g., in one or more columns of data structure  500 ) is below a predetermined threshold. As another example, an image associated with a medium degree may be displayed if the absolute value of a sum of the scores for the search results or documents (e.g., in one or more columns of data structure  500 ) is below a first predetermined threshold and/or above a second predetermined threshold. As a further example, an image associated with a high degree may be displayed if the absolute value of a sum of the scores for the search results or documents (e.g., in one or more columns of data structure  500 ) is above a predetermined threshold. 
     Each image displayed in region  1640  may be determined based on at least one classification associated with the search results or documents (e.g., from column  1040  of data structure  1000 ). For example, a first image associated with a first classification may be displayed if any search results are associated with the first classification, a second image associated with a second classification may be displayed if any search results are associated with the second classification, etc. 
     In one embodiment, an image associated with sentiment data may include at least one icon (e.g.,  1652  of  FIG. 16B, 1662  of  FIG. 16B, 1672  of  FIG. 16B, 1682  of  FIG. 16B, 1684  of  FIG. 16B , etc.) associated with at least one search result. For example, icon  1652  may be displayed (e.g., in or around region  1650 ) to indicate a sentiment (e.g., a score, a category, a degree, a classification, some combination thereof, etc.) associated with a first search result or document (e.g., “Document  1 ”), icon  1662  may be displayed (e.g., in or around region  1660 ) to indicate a sentiment (e.g., a score, a category, a degree, a classification, some combination thereof, etc.) associated with a second search result or document (e.g., “Document  2 ”), icon  1672  may be displayed (e.g., in or around region  1670 ) to indicate a sentiment (e.g., a score, a category, a degree, a classification, some combination thereof, etc.) associated with a third search result or document (e.g., “Document  3 ”), icon  1682  may be displayed (e.g., in or around region  1680 ) to indicate a sentiment (e.g., a score, a category, a degree, a classification, some combination thereof, etc.) associated with a fourth search result or document (e.g., “Document  4 ”), etc. Although numbers are shown in each of the regions (e.g.,  1652 ,  1662 ,  1672 ,  1682 , etc.) in  FIG. 16B , it should be appreciated that other icons (e.g., thumbs up, thumbs down, a particular number of stars, etc.) may be displayed or used in other embodiments. 
     As another example, other icons or images may be displayed to indicate other features related to sentiment. For example, arrow  1684  may be displayed to indicate that the word “good” is an effecting portion that modifies or expresses a sentiment of the word “handling” (e.g., the affected portion). It should be appreciated that effecting portions can modify affected portions in other sentences, paragraphs, etc., and therefore, icons or images such as arrow  1684  may assist the viewer or user in quickly and easily determining the types and relationships of different portions of one or more documents. 
     In one embodiment, an image associated with sentiment data may include formatting of text associated with at least one search result. The formatting may include highlighting (e.g., displaying the text contemporaneously with an overlapping image that is a different color, shade, etc. than the background of the encompassing region and/or the text), bolding, underlining, italicizing, making larger, making smaller, superscripting, subscripting, changing the color of, capitalization, alternatively formatting, some combination thereof, etc. 
     The formatted text may include at least one effecting portion (e.g., “very good” and “bad” of “Document  1 ,” “very good” of “Document  2 ,” “bad” of “Document  3 ,” “good” of “Document  4 ,” etc.) and/or at least one affected portion (e.g., “steering” and “fuel economy” of “Document  1 ,” “engine” of “Document  2 ,” “acceleration” of “Document  3 ,” “handling” and “braking” of “Document  4 ,” etc.). In this case, each effecting portion is shown with highlighting, whereas each affected portion is shown with other formatting (e.g., underlining, bolding, italicizing, strikethrough, etc.). As such, a viewer or user may quickly determine which portions of the search results or documents are effecting portions and affected portions. Additionally, display of the image (e.g., including the formatted text) may allow additional information (e.g., a sentiment score, a sentiment category, a sentiment degree, a sentiment classification, etc.) to be quickly and intuitively deduced (e.g., without displaying the additional information), where the additional information may be deduced based on the content of the effecting portions and/or the affected portions, based on the context of the effecting portions and/or the affected portions in the search results or documents, etc. 
     In one embodiment, different portions of text may be formatted differently to indicate different sentiment scores, different sentiment categories, different sentiment degrees, different sentiment classifications, etc. For example, affected portions associated with a positive sentiment may be formatted or displayed using green text, affected portions associated with a negative sentiment may be formatted or displayed using red text, affected portions associated with a neutral sentiment may be formatted or displayed using white text, etc. As another example, affected portions associated with a positive sentiment may be underlined (e.g., “steering” of “Document  1 ,” “engine” of “Document  2 ,” “handling” and “braking” of Document  4 , etc.), whereas affected portions associated with a negative sentiment may be formatted with a strikethrough (e.g., “fuel economy” of “Document  1 ,” “acceleration” of “Document  3 ,” etc.). 
     As a further example, affected portions associated with a low degree of sentiment may be italicized (e.g., “handling” and “braking” of “Document  4 ,” etc.), whereas affected portions associated with a medium degree of sentiment may be italicized and bolded (e.g., “engine” of “Document  2 ,” etc.). And as yet another example, a label associated with a low degree of sentiment (e.g., “low,” etc.) may be displayed adjacent to or near affected portions associated with a low degree of sentiment (e.g., “acceleration” of “Document  3 ,” etc.), whereas a label associated with a medium degree of sentiment (e.g., “med,” etc.) may be displayed adjacent to or near affected portions associated with a medium degree of sentiment (e.g., “steering” of “Document  1 ,” etc.). 
       FIG. 16C  shows exemplary on-screen graphical user interface (GUI)  1600 C for displaying sentiment data associated with at least one search result in accordance with one embodiment of the present invention. In one embodiment, GUI  1600 C may be used to implement or be displayed in region  1620  of GUI  1600 A of  FIG. 16A . And in one embodiment, GUI  1600 C may be used to implement or be displayed as at least a portion of a webpage. 
     As shown in  FIG. 16C , GUI  1600 C may include at least one element (e.g.,  1691 ,  1692 ,  1693 ,  1694 ,  1695 ,  1696 ,  1697 , etc.) in region  1690 . Each element may be associated with a respected affected portion (e.g., associated with one or more of the search results or documents of GUI  1600 B) in one embodiment. Additionally, each element may include a respective image associated with respective sentiment data (e.g., a score, a category, a degree, a classification, etc.) corresponding to a respective affected portion, where the respective images may include backgrounds behind text associated with the affected portions, icons associated with the affected portions, formatting (e.g., highlighting, bolding, underlining, italicizing, making larger, making smaller, superscripting, subscripting, changing the color of, capitalization, alternatively formatting, etc.) of text associated with the affected portions, some combination thereof, etc. 
     Accordingly, GUI  1600 C may provide information about respective sentiments of respective affected portions of the search results. In one embodiment, the sentiment data presented using GUI  1600 C may be determined using sentiment data from multiple search results or documents (e.g., by adding, averaging, etc. the respective sentiment data of each search result or document to determine the combined sentiment data). Moreover, this information may be conveyed in a compact and intuitive form using GUI  1600 C. 
     In one embodiment, one or more of the elements (e.g.,  1691 ,  1692 ,  1693 ,  1694 ,  1695 ,  1696 ,  1697 , etc.) of GUI  1600 C may be associated with other data (e.g., at least one theme, at least one theme element, at least one semantic key, at least one semantic sub-key, etc.) associated with at least one affected portion of a document. In one embodiment, the other data may be determined or accessed (e.g., in accordance with step  1120  of process  1100 ) based on one or more portions of a query (e.g., where the first data accessed in step  1110  of process  1100  includes at least one portion of a query such as query  1350 ), where the one or more portions of the query do not include the other data. 
     For example, data associated with a search (e.g.,  1310 ) may include: a query (e.g.,  1350 ) of “Toyota Land Cruiser” and “performance;” and the command of “sentiment” (e.g., associated with or requesting any category of sentiment such as positive, negative, neutral, some combination thereof, etc.) modifying or associated with the query portion “performance.” A search may be performed (e.g., in accordance with step  1220  of process  1200 ) to generate search results (e.g., accessed in accordance with step  1230  of process  1200 ) including one or more documents that include: the words or phrases “Toyota Land Cruiser” and “performance;” and at least one affected portion (e.g., associated with any category of sentiment as selected or indicated based on the command “sentiment”) including the word “performance” or other data associated therewith (e.g., at least one theme associated with “performance,” at least one theme element associated with “performance,” at least one semantic key associated with “performance,” at least one semantic sub-key associated with “performance,” some combination thereof, etc.). In one embodiment, the other data associated with the word “performance” may include the words “steering,” “fuel economy,” “engine,” “acceleration,” “handling,” “braking,” etc. 
     Sentiment data associated with the word performance or the other data associated therewith (e.g., the words “steering,” “fuel economy,” “engine,” “acceleration,” “handling,” “braking,” etc.) may be accessed (e.g., in accordance with step  1240 ). For example, sentiment data associated with the word “steering” may include a score of “+2” (e.g., based on the effecting portion “very good” as shown in  FIG. 16B ), sentiment data associated with the word “fuel economy” may include a score of “−1” (e.g., based on the effecting portion “bad” as shown in  FIG. 16B ), sentiment data associated with the word “engine” may include a score of “+2” (e.g., based on the effecting portion “very good” as shown in  FIG. 16B ), sentiment data associated with the word “acceleration” may include a score of “−1” (e.g., based on the effecting portion “bad” as shown in  FIG. 16B ), sentiment data associated with the word “handling” may include a score of “+1” (e.g., based on the effecting portion “good” as shown in  FIG. 16B ), sentiment data associated with the word “braking” may include a score of “+1” (e.g., based on the effecting portion “good” as shown in  FIG. 16B ), etc. Data for displaying an image associated with the sentiment data (e.g., associated with the word “performance” or other data associated therewith) may be generated (e.g., in accordance with step  1250  of process  1200 ) and/or the image may be displayed (e.g., in accordance with step  1250  of process  1200 ) to produce a GUI (e.g.,  1600 C of  FIG. 16C ) that includes the sentiment data (e.g., respective sentiment data associated with each of the elements  1691 ,  1692 ,  1693 ,  1694 ,  1695 ,  1696 ,  1697 , etc.). 
     Accordingly, in one embodiment, a GUI (e.g.,  1600 C) may be generated and/or displayed that advantageously includes sentiment data associated with other data (e.g., the words “steering,” “fuel economy,” “engine,” “acceleration,” “handling,” “braking,” etc.) that is not part of the query (e.g., which includes the word “performance” but does not include the words “steering,” “fuel economy,” “engine,” “acceleration,” “handling” or “braking”). As such, a user entering the query need not know the other data associated with the word performance or spend the time and effort to enter those words in as part of the query. Instead, embodiments may automatically determine those words (e.g., as one or more themes, one or more theme elements, one or more semantic keys, one or more semantic sub-keys, etc.) based on the simpler and more concise query of “Toyota Land Cruiser” and “performance,” where those words (e.g., the “other data”) may then be used to generate and/or display the GUI (or perform at least one operation associated with the search results such as filtering, ranking, etc.). Thus, the GUI may provide valuable and relevant information by displaying the sentiment (e.g., associated with sentiment data) of one or more features (e.g., “steering,” “fuel economy,” “engine,” “acceleration,” “handling,” “braking,” etc.) of the Toyota Land Cruiser as determined from at least one search result or document. Further, the sentiment data (e.g., of GUI  1600 C) may be displayed contemporaneously with the corresponding search results (e.g., of GUI  1600 B) as an image or GUI (e.g.,  1600 A) in one embodiment, thereby providing even more valuable and relevant information related to the initial query (e.g., which may be displayed in region  1610  of GUI  1600 A). 
     In one embodiment, the data of the previous example may be entered (e.g., by a user, automatically, etc.) using a GUI (e.g.,  1400 A of  FIG. 14A, 1400B  of  FIG. 14B, 1500  of  FIG. 15 , etc.). For example, “Toyota Land Cruiser” may be entered in region  1411 , “performance” may be entered in region  1431 , and the command may be entered using region  1431  (e.g., by entering “sentiment: performance,” etc.) and/or using region  1432 . As another example, “Toyota Land Cruiser” may be entered in region  1431 , “performance” may be entered in region  1411 , and the command may be entered using region  1411  (e.g., by entering “sentiment: performance,” etc.) and/or using region  1412 . 
     In one embodiment, the other data may not be found in the search results or documents (e.g., of GUI  1600 B). In this case, another portion of data may be determined this can be found in the search results or documents and also that is associated with sentiment data. For example, where the word “engine” is not found in at least one document, the word “motor” may be determined (e.g., to be a theme where “engine” is a theme element, to be a theme element where “engine” is a theme, to be a semantic key where “engine” is a semantic sub-key, to be a semantic sub-key where “engine” is a semantic key, etc.). Sentiment data associated with “motor” may be applied to “engine,” thereby allowing sentiment data to be displayed (e.g., using GUI  1600 C) for “engine” even though “engine” may not be found in at least one document. 
     Although  FIGS. 16A, 16B and 16C  show GUIs (e.g.,  1600 A,  1600 B and  1600 C, respectively) with a specific number and arrangement of elements, it should be appreciated that the GUIs (e.g.,  1600 A,  1600 B and  1600 C) may include a different number and arrangement of elements in other embodiments. For example, GUI  1600 A may include more or less than three regions (e.g.,  1610 ,  1620 ,  1630 , etc.) in other embodiments. As another example, GUI  1600 B may include more or less than four regions (e.g.,  1650 ,  1660 ,  1670  and  1680 ) in other embodiments. And as yet another example, elements of GUI  1600 B and/or GUI  1600 C may have a different appearance, content, etc. in other embodiments. 
     In one embodiment, a user could be charged based on the number of searches carried out for which sentiment data is accessed. A user could be charged based on the number of results returned as a result of the search (e.g., performed in step  1220  of process  1200 ) in one embodiment. A user could be charged based on the number of search results or documents associated with the sentiment data (e.g., accessed in step  1240 ) in one embodiment. And in one embodiment, a user could be charged based on a number of accesses to sentiment data (e.g., in step  1240  of process  1200 ) and/or an amount of sentiment data accessed (e.g., in step  1240  of process  1200 ). Accordingly, one or more features of the sentiment analysis (e.g., as discussed or shown with respect to GUI  1400 A, GUI  1400 B, GUI  1500 , GUI  1600 A, GUI  1600 B, GUI  1600 C, etc.) may be enabled or offered to certain users responsive to payment in one embodiment. 
     In one embodiment, the sentiment data (e.g., accessed in step  1240 , shown in GUI  1600 B, etc.) may be used to determine or select advertising content. The advertising content may be displayed (e.g., using GUI  1600 A, GUI  1600 B, GUI  1600 C, etc.) contemporaneously with the search results and/or the sentiment data associated with the search results in one embodiment. For example, where the search term or query is “Nikon D7000” and the sentiment data associated with the search results is positive, then advertising content for the Nikon D7000 camera may be displayed contemporaneously with the search results and/or the sentiment data associated with the search results. As another example, where the search term or query is “Nikon D7000” and the sentiment data associated with the search results is negative, then advertising content for another brand or model of camera may be displayed contemporaneously with the search results and/or the sentiment data associated with the search results. In this manner, relevant advertising content may be provided or displayed at a time where a consumer is more likely to purchase a product or service (e.g., responsive to the display of positive sentiment data related to the product or service of the query, responsive to the display of negative sentiment data related to another product or service of the query, etc.).
