     DETAILED DESCRIPTION 
       [0011]    The quality of web search experience can be improved by refining the search terms or search results based on the context in which user is conducting the search. For instance, a search for the term “labor” by a woman may be more refer to “pregnancy” than “labor union” (politics) or “unemployment.” In implementation, the present technique may encompass a divide-and-conquer strategy for refining the query. In certain embodiments, the input search query may be categorized in at least three categories or classes: (1) Word Sense Disambiguation Queries are those queries which have more that one synonym, some of which are more relevant to the user conducting the query; (2) Perspective Queries are those wherein the expected results of the query is different for different types of users (e.g., a woman search the term “shoes” might expect results corresponding to “shoes for females”); (3) Default Queries are those queries wherein there is not particular result refinement required for the user. As discussed below, each of the above three categories may have a Query Augmenter module associated with it. Once the query is classified, it may be forwarded to the corresponding Query Augmenter module for handling. The selected query augmenter module may augment the query with additional keyword terms. The augmented query may then be submitted to a regular search engine and the results returned to the user. The technique may improve the search quality of a given community of users. This can in turn increase the popularity of the search product and greater revenues can be generated by increased traffic with click-through advertisements and banner advertisements, for example. It should be noted that a given community may be defined or encompass a variety of formats. For example, a community may be visitors to a given web site (e.g., ivillage.com), visitors to a personal website (e.g., Linekdin or Facebook), readers on a particular blog, or any implicitly defined community, and so on. 
         [0012]    The product can offer web search services for a targeted community of users. Thereby the product has an edge over conventional search engines which are mostly targeted for general users. Again, the popularity of the product can be converted to revenues by means of click-through advertisements and banner advertisements. A novelty of the technique is that queries may be categorized and the augmented based on the category in which the query falls. 
         [0013]    Referring to the drawings,  FIG. 1  depicts a system  10  for conducting a computerized search. The system  10  may be implemented on a computer or server having executable code stored in memory, for example. In the system  10 , a query is received from a user  12  to a classifier  14 . In the illustrated embodiment, the classifier  14  classifies the query into one of three categories and forwards the query to the appropriate augmenter module  16 ,  18 , or  20 . It should be emphasized that the number of categories and associated augmenter modules  16 ,  18 , or  20  may encompass less than three or more than three The word sense disambiguation augmenter module  18  and the perspective query augmenter module  18  augments the query, such as by adding an additional word to the query. Again, the word sense disambiguation queries may be those queries which have more that one synonym, some of which are more relevant to the user conducting the query. Determination of word sense disambiguation may be performed with a thesaurus, such as Wordnet, in conjunction with analysis of results from a knowledge base (e.g., from an internal search on a specific web site such as ivillage.com). Perspective queries may be those wherein the expected search results of the query vary for different types of users. The query can be classified as “broad”, “specific” or “sexual”, and so on, by suitable analysis. The unambiguous query augmenter module  20  does not modify the query but instead passes the default query unaffected. To perform the search, a meta-search engine module  22  submits or issues the modified query (or unmodified query) to a search engine  24 , such as a conventional search engine. The conventional search engine generates the search results (based on the query received from the engine module  22 ) as per its algorithm, for example. Search results generated may be supplied from the search engine  24  back to the user. 
         [0014]      FIG. 2  depicts a method  40  for conducting a computerized search. Initially, a query is received (block  42 ) from a user, for example. The query is then classified (block  44 ). As indicated, exemplary categories for classification include: (1) word sense disambiguation; (2) perspective; and (3) unambiguous. The query is then augmented based on the classification (block  46 ). Augmentation may involve adding one or more words to the query. As mentioned, the query may not be augmented for those instances, such as with the unambiguous category, where there is not a particular result refinement required or beneficial for the user. The augmented query or unchanged query may be automatically submitted or issued (block  48 ) to a search engine, for example, as a query for a search. Finally, the search may be conducted based on the augmented query or unchanged query (block  50 ). It should be noted that all elements of the method may be conducted automatically without user intervention. 
         [0015]    In other aspects, the present technique may provide the general user with the ability to conduct general Internet searches from the perspective of a knowledge base or database. For example, information indexed by search engines on the Internet can be characterized as at least two forms: information meant for the layman, and information meant for the professional. Within a given domain, such as a medical domain, the general user has the ability using known terms to search and retrieve information indexed in databases for the layman. However, the present technique may give the general user the ability to retrieve information indexed in databases for the professional, for example, by mapping their query into the appropriate professional terms and keywords and expanding it with appropriate relevant keywords and concepts. The present technique uses a knowledge base, or set of documents, to map and expand a search query to be performed over the Internet, which may or may not include the documents forming that knowledge base. 
         [0016]    Certain embodiments may have several features to address the problem of enabling the general user to perform a search query from the perspective of the knowledge base. Again, employment of the knowledge base maps and/or expands the original search query. The knowledge base could be offline, proprietary, or other data that represents the target perspective. Further, a statistical approach may decide to map and/or expand a search query when the knowledge base has enough “support” for that mapping and/or expansion, for example. Moreover, the technique may employ the general approach of mapping a search query into new keywords or terms from the knowledge base, as well as the general approach of expanding a search query with related keywords or terms to the original or mapped query. Lastly, a search engine specific approach may be utilized to perform the mapping and expansion of the original search query to increase relevance based on the performance of a specific search engine. 
         [0017]      FIG. 3  depicts a method  60  for conducting a computerized search. A search query is received (block  62 ) from a user, for example. A knowledge base is analyzed (block  64 ). The search query is then mapped, changed, and/or expanded based on the analysis of the knowledge base (block  66 ). It should be noted that embodiments of the present technique differ from contextual search engines in that the present technique may rely upon a specific set of documents (i.e., knowledge base), to map and/or expand a search query for searching within another set of documents that may or may not contain the knowledge base. The present technique may treat the knowledge base as the default “context” of the search query. After mapping and/or expanding the search query based on the knowledge base, a new search query may be submitted to another search engine (block  68 ), thereby giving bias to the knowledge-base (subset of documents). A search is then conducted based on the modified query (block  70 ). It should be noted that the computer searches discussed herein may be conducted from a personal computer, mobile computer or laptop, personal digital assistant (PDA), cell phone, other appliances, and so on. 
         [0018]    In sum, the technique makes novel use of the set of documents comprising the knowledge base. The technique employs a knowledge base to map and/or expand a search query for submission to another search engine to provide the user the ability to search with the perspective of the knowledge base. This may be in contrast to providing enhanced search over a set of documents based on that set of documents, or with the assistance of a very small user submitted set of keyword or terms which are either used to expand the query or are themselves filtered by the same set of documents prior to expanding the search query. 
         [0019]    Further, the technique may be employed as a part or component of an integrated product. The technique concerns the mapping and/or expansion of a general search query based on a knowledge base for a specific search engine. The product may also contain a system and method to produce the knowledge base, to interface to a specific search engine, to adjust the result set from the specific search engine after submitting the new mapped and/or expanding query, and so on. 
         [0020]    While only certain features of the invention have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
