     DETAILED DESCRIPTION 
     Introduction 
     Despite the myriad sources of on-demand information available to the public today, the accuracy and quality of much of this information is questionable. There is no guarantee that any online content originates from sources that are authoritative or have any pertinent education or knowledge. The EXP introduces a new type of content platform that delivers expert answers to crowd-sourced user questions. Using the EXP, experts may provide answers (e.g., in the form of video-blogs) to such crowd-sourced user questions. The EXP may also serve as a marketing platform for experts. Experts may post entries on topical issues in their area of expertise, build a following among the public, promote the expert&#39;s books and/or research, obtain funding for their activities, and/or the like. 
     DETAILED DESCRIPTION OF THE EXP 
       FIG. 1  shows an exemplary usage scenario in one embodiment of the EXP. In  FIG. 1 , a user  101 A may have a question regarding a topic (e.g., technology). The user may ask the question via the EXP Server  106  to obtain an answer from an expert. Another user  102 B may also be interested in the answer to this question. The other user may utilize the EXP Server to indicate interest in having the question answered (e.g., by voting for the question). 
     The EXP Server may prompt one or more experts to answer the question. The EXP Server may contact those experts who are best suited to answer the question. For example, the EXP Server may contact technology experts  110 A-C to answer questions regarding technology. In another example, the EXP Server may contact economics experts  114 A-C to answer questions regarding economics, but may not contact economics experts to answer questions regarding technology. The EXP Server may prompt experts to answer the question once enough users indicate interest in having the question answered (e.g., to ensure that experts are asked high quality questions), or may sort questions such that the questions with the most user interest are presented to experts first (e.g., to make it convenient for experts to answer high quality questions). 
     One or more experts (e.g., technology expert  110 A) may provide a video recording with an answer via the EXP Server. An expert may provide the answer at a time and place that is convenient to the expert, and may embed supporting materials (e.g., images, links to websites) in the answer. Post-processing may be applied to answers to ensure consistent video and/or audio quality. 
     The EXP Server may inform users who are interested in having the question answered that an answer to the question is available. For example, the EXP Server may send such users an email. In another example, such users may check to see if any new answers to the question are available via a website. 
     If a user finds an answer insightful, the user may wish to follow the expert who provided the answer. For example, following the expert may facilitate alerting the user when the expert answers other questions. In another example, following the expert may facilitate informing the user regarding the expert&#39;s activities (e.g., books written by the expert) and/or helping the user support such activities (e.g., purchase the expert&#39;s book). Furthermore, the EXP may facilitate sharing the answer with and/or recommending the expert to the user&#39;s EXP friends and/or via Facebook, Twitter, email, and/or the like. 
       FIG. 2  shows a logic flow diagram illustrating an exemplary question answering (QA) component in one embodiment of the EXP. In  FIG. 2 , a question from a user may be obtained at  201 . The user may provide a question via a client (e.g., a desktop, a laptop, a tablet, a smart phone, and/or the like). In one embodiment, the user may input a question in a textual and/or graphical form. For example, the user may type in a question and/or provide a picture (e.g., as supporting information). In another embodiment, the user may input a question in an audio and/or video form. For example, the user may use a microphone and/or a webcam to record a question. In some implementations, an audio and/or video question may be converted to a textual form (e.g., using speech recognition software). 
     A determination may be made at  205  whether other questions have been asked that are similar to the question obtained from the user. In one embodiment, a textual search may be performed by the EXP to make this determination. For example, a full-text search may be performed via MySQL using one or more SQL commands substantially in the following form:
         SELECT *   FROM Questions   WHERE MATCH(QuestionContent) AGAINST(“user&#39;s question”)
 
In another embodiment, topics and/or tags associated with the user&#39;s question may be used by the EXP to make this determination. For example, topics and/or tags associated with the user&#39;s question may be compared to topics and/or tags associated with existing questions to find questions that have the most topics and/or tags in common with the user&#39;s question.
       

     If similar questions have been asked, the EXP may present the user with similar questions at  242 . For example, the EXP may present the user with a list of similar questions via a GUI widget (e.g., a dropdown box). In one implementation, as the user types in a question, the EXP may update the list of similar questions and the user may click on one of the similar questions to select it. A determination may be made at  246  whether the user selected one of the similar questions. If the user did not select a similar question or if similar questions have not been asked, the EXP may create a question at  210 . For example, the EXP may add the user&#39;s question to a data store (e.g., a questions data store  730   c ) via one or more SQL statements substantially in the following form:
         INSERT INTO Questions (Question ID, QuestionContent)   VALUES (“question identifier”, “user&#39;s question”)       

     The user&#39;s question may be associated with one or more topics at  212 . For example, topics may include art, history, science, business, technology, literature, music, politics, and/or the like. In one embodiment, topics may be predefined by the EXP (e.g., via a topics data store  730   e ). In another embodiment, topics may be defined by users. In various implementations, topics may include a one-level structure, a two-level structure (e.g., topics and sub-topics), a multi-level structure, and/or the like. In one embodiment, the EXP may assign one or more topics to the user&#39;s question (e.g., using keyword analysis). For example, keywords may be associated with topics (e.g., the keyword “laptop” may be associated with the topic “technology”) and questions may be assigned a topic based on keywords in the question. In another embodiment, the user may assign one or more topics to the user&#39;s question (e.g., by selecting one or more of the predefined topics and/or sub-topics via a GUI). For example, the entry for the user&#39;s question in the questions data store may be associated with assigned topics from the topics data store via one or more SQL statements substantially in the following form:
         UPDATE Questions   SET QuestionTopics=“Technology”   WHERE QuestionID=“question identifier”       

     The user&#39;s question may be associated with one or more tags at  214 . For example, tags may include keyword tags, social networking tags (e.g., Twitter hash tags, Facebook tags), and/or the like. In one embodiment, tags may be predefined by the EXP (e.g., via a tags data store  730   f ). In another embodiment, tags may be defined by users. In one embodiment, the EXP may assign one or more tags to the user&#39;s question (e.g., using keyword analysis). For example, keywords may be associated with tags (e.g., the keyword “laptop” may be associated with the tag “computer”) and questions may be assigned tags based on keywords in the question. In another embodiment, the user may assign one or more tags to the user&#39;s question (e.g., by specifying one or more tags). For example, the entry for the user&#39;s question in the questions data store may be associated with assigned tags from the tags data store via one or more SQL statements substantially in the following form:
         UPDATE Questions   SET QuestionTags=“computer”   WHERE QuestionID=“question identifier”       

     The user&#39;s question may be assigned a rating at  216 . The rating may indicate interest in, importance of, urgency of, and/or the like of the user&#39;s question. For example, one or more SQL statements may be used to store the rating in the questions data store. In one embodiment, a question may be assigned a predefined rating associated with new questions (e.g., a rating of 1). In another embodiment, a question (e.g., associated with a topic) may be assigned a rating that varies based on the characteristics of the user who asked the question (e.g., if the question was asked by a user who is an expert in the topic, the question may get a higher rating of 2). In yet another embodiment, the user may indicate the user&#39;s interest in having a question answered and/or the priority assigned to a question by the user (e.g., a low interest/priority question may get a rating of 0.5, a medium interest/priority question may get a rating of 1, a high interest/priority question may get a rating of 1.5). 
     If the user did select a similar question at  246 , a determination may be made at  248  whether the selected question has been answered. If the selected question has not been answered, the EXP may facilitate voting for the selected question at  221 . Voting for a question allows a user to indicate interest in having the question answered by an expert. In one embodiment, the user may use a GUI widget (e.g., a “Vote” button) to vote for a question. In one implementation, the user may be offered an opportunity to vote for a question. In another implementation, the user may be offered an opportunity to express the level of interest in having a question answered and/or the priority assigned to a question by the user. 
     The rating associated with the selected question may be updated at  225 . In one embodiment, the rating associated with a question may be updated by a predefined amount associated with having an additional user vote for a question (e.g., increased by 1). In another embodiment, the rating associated with a question (e.g., associated with a topic) may be updated based on the characteristics of the user who voted for the question (e.g., if the question was voted for by an expert on the topic, the question&#39;s rating may be increased by 2). In yet another embodiment, the rating associated with a question may be updated based on the voter&#39;s level of interest in having a question answered and/or the priority assigned to a question by the user. For example, the rating may be increased by 0.5 for a low interest/priority question, by 1 for a medium interest/priority question, and by 1.5 for a high interest/priority question. In one implementation, the rating associated with the selected question may be updated via one or more SQL statements substantially in the following form:
         UPDATE Questions   SET Question Rating=“new rating”   WHERE QuestionID=“question identifier”       

     One or more experts who may be well suited to answering the outstanding question (i.e., either the user&#39;s question or the similar question selected by the user) may be determined at  230 . It is to be understood that the term “expert” refers generally to EXP users who are well qualified to answer questions on one or more topics. For example, experts may include subject matter experts (e.g., academics, industry experts), business leaders, celebrities, intellectuals, public officials, politicians, and/or the like. In one implementation, the user may direct the question to one or more experts chosen by the user. For example, the user may click an “Ask a Question” button on the profile page of the expert whom the user wishes to ask the question. In another implementation, the EXP may determine one or more best-rated experts using a variety of factors associated with each expert. In one embodiment, an expert&#39;s established reputation may be assessed. For example, the number and/or character of the expert&#39;s awards, peer reviews, media reviews, and/or the like may be evaluated. In another embodiment, the expert&#39;s field of expertise may be assessed. For example, the expert&#39;s field of research, the number and/or character of publications, the number of years spent in the field, and/or the like may be evaluated. In yet another embodiment, the level of the expert&#39;s public engagement may be assessed. For example, the expert&#39;s interest in and/or track record of participating in public discourse may be evaluated. In yet another embodiment, the expert&#39;s social impact may be assessed. For example, the expert&#39;s communication skills (e.g., reputation for explaining complex topics) may be evaluated. In one implementation, ratings (e.g., numerical ratings) may be assigned to experts based on the assessment of one or more of the above factors (e.g., overall ratings, ratings for each topic and/or subtopic and/or tag). In another implementation, ratings may be assigned to experts based on self assessment of expertise by preapproved experts. One or more best-rated experts (e.g., having highest numerical rating with regard to the topic associated with the outstanding question) may be selected to provide answers. See  FIG. 4  for additional detail regarding determining one or more experts to answer a question. 
     Priority associated with the outstanding question may be determined at  235 . Such priority may be determined based on the rating associated with the outstanding question. For example, questions that are highly rated may be considered to have higher priority since these questions may be of higher interest to EXP users. In one embodiment, the priority associated with the outstanding question may determine how the outstanding question is presented to an expert. For example, upon login, an expert may be presented with a list of questions sorted based on question priority. In another example, questions with a higher priority may be displayed more prominently (e.g., questions may be highlighted using different colors based on their priority, questions whose rating exceeds a predefined threshold may be highlighted). In another embodiment, the priority associated with the outstanding question may determine how an expert is alerted regarding the outstanding question. For example, the expert may be alerted and/or reminded that a question is awaiting the expert&#39;s response based on the question&#39;s priority (e.g., the frequency of alerts and/or reminders sent to the expert regarding a question may vary based on the question&#39;s priority, the expert may be sent alerts and/or reminders regarding those questions whose priority exceeds a predefined threshold). 
     An expert associated with the outstanding question may be presented with the outstanding question at  241 . In one embodiment, the expert may select the outstanding question from a list of questions assigned to the expert (e.g., via a webpage) and view, listen to, and/or the like the outstanding question. In another embodiment, an electronic communication (e.g., an email) with the outstanding question may be sent to the expert. 
     The EXP may obtain an answer to the outstanding question from the expert at  243 . For example, the answer may be stored in an answers data store  730   d . In various embodiments, the answer may be a video-blog, an audio recording, a textual response, and/or the like. For example, the expert may use his client (e.g., a tablet with a webcam) to record and/or post a video-blog answer at his chosen time and/or location. See  FIG. 5  for additional detail regarding obtaining the answer from the expert. In some embodiments, the expert may choose to share the answer with the expert&#39;s social network (e.g., via Facebook, via Twitter). In some embodiments, the expert&#39;s answer may be a response to an answer to the outstanding question provided by another expert. For example, if a user is an expert on the topic associated with the outstanding question, the user may see a “Respond” button that allows the user to record a response to another expert&#39;s answer. Accordingly, the EXP may provide an asynchronous debate venue in which different experts may present different views. 
     The answer may be associated with the answered question and thus may be associated with the topic at  245  and/or with the tags at  247  associated with the answered question. In some embodiments, the expert may associate the answer and thus the question with additional and/or alternative topics at  245  and/or tags at  247 . In some embodiments, the user who asked the question may be allowed to associate the question with topics, while the expert may be allowed to associate the answer and thus the question with tags. 
     If, at  248 , it is determined that the selected question has been answered, or if the outstanding question has been answered by an expert, the EXP may present the user with a list of answers to the answered question at  250 . In some embodiments, the answers may be sorted (e.g., based on the date the answer was provided, based on the answer&#39;s popularity). See  FIG. 6  for additional detail regarding presenting the user with answers. For example, if multiple experts provided answers, the user may choose which answer to view (e.g., by selecting an answer to view via a GUI). 
     The EXP may obtain a selection of an answer to view from the user at  255  and may present the selected answer to the user at  260 . For example, the EXP may facilitate showing the user the selected video-blog answer. A determination may be made at  265  whether the user is satisfied with the selected answer. If the user indicates that the user is not satisfied (e.g., the answer is not clear, the user wishes to view other answers) with the selected answer, the user may be presented with a list of answers at  250  and provided with an opportunity to select a different answer. 
     If the user is satisfied with the answer the EXP may facilitate a variety of activities at  270 . In one embodiment, the EXP may facilitate sharing the answer with and/or recommending the expert to the user&#39;s social network. For example, the EXP may facilitate sharing the answer with and/or recommending the expert to the user&#39;s EXP friends and/or via Facebook, Twitter, email, and/or the like. In another example, the user may post comments regarding questions and/or answers. 
     In another embodiment, the EXP may facilitate following of the expert and/or of the topic by the user. For example, if the user chooses to follow the expert, the EXP may provide the user with a readily accessible link (e.g., on the user&#39;s homepage) to the expert&#39;s profile page, alerts regarding activities of the expert, and/or the like. The user may access the expert&#39;s profile page to view the expert&#39;s posts on topical issues in the expert&#39;s area of expertise, to view answers to other questions answered by the expert, to view the expert&#39;s media articles and/or interviews, to ask the expert follow up questions regarding the question, and/or the like. In another example, if the user chooses to follow a topic, the EXP may provide the user with a readily accessible link to other questions and/or answers associated with the topic. 
     In yet another embodiment, the EXP may facilitate user support of the expert. For example, the expert&#39;s profile page may provide information regarding the expert&#39;s curriculum vitae (CV), books (e.g., based on the list of expert&#39;s books obtained via an online bookstore&#39;s API using keywords), podcasts, research, articles, speaking activities, and/or the like. The EXP may serve as a funding channel for the expert by facilitating the purchase of such materials (e.g., books), by facilitating user funding (e.g., donations) for various (e.g., research) activities, causes, non-profit organizations, and/or the like that the expert wishes to engage in and/or support. For example, an expert may post on the expert&#39;s profile page that the expert wishes to undertake a research project to examine tax policies in Toronto. The expert may specify the amount of funding requested and/or the time in which the funding has to be obtained in order for the research project to commence. 
       FIG. 3  shows a data flow diagram in one embodiment of the EXP. In  FIG. 3 , dashed lines indicate data flow elements that may be more likely to be optional.  FIG. 3  provides an example of how data may flow to, through, and/or from the EXP to obtain an answer to a user&#39;s question from an expert. In  FIG. 3 , the user  302  may input a question  331  into the user&#39;s client  306 . For example, the user may type in a question. The user&#39;s client may communicate a question request  335  to the EXP server  310 . For example, the question request  335  may include data such as the user&#39;s ID, question content, topics, tags, and/or the like, and may be in XML format substantially in the following form: 
     
       
         
           
               
               
             
               
                   
                   
               
             
            
               
                   
                 &lt;XML&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;QuestionRequest&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;UserID&gt;ID_User2&lt;/UserID&gt; 
               
               
                   
                 &lt;QuestionID&gt;ID_Question2&lt;/QuestionID&gt; 
               
               
                   
                 &lt;QuestionContent&gt;user&#39;s question&lt;/QuestionContent&gt; 
               
               
                   
                 &lt;QuestionTopic&gt;Technology&lt;/QuestionTopic&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;/QuestionRequest&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;/XML&gt; 
               
               
                   
                   
               
            
           
         
       
     
     The EXP server may analyze question data  339  to determine topics and/or tags that should be associated with the question. The EXP server may also analyze question data  339  to determine whether other questions have been asked that are similar to the question obtained from the user. For example, the question data may include question keywords, topics, tags, and/or the like. 
     If similar questions have been asked and the user selects a similar question, data regarding the similar question  343  may be provided to the user&#39;s client. For example, data regarding the similar question  343  may include question ID, question content, question rating, and/or the like, and may be in XML format substantially in the following form: 
     
       
         
           
               
               
             
               
                   
                   
               
             
            
               
                   
                 &lt;XML&gt; 
               
            
           
           
               
               
            
               
                   
                 &lt;SimilarQuestion&gt;

     The EXP server may analyze experts data  359  to determine which experts should be asked to answer the question. For example, the experts data may include experts&#39; IDs, experts&#39; overall ratings, experts&#39; topic ratings, experts&#39; subtopic ratings, and/or the like. The EXP server may analyze votes data  361  to determine priority for the question. For example, votes data may include question ID, question rating, vote indicators, vote amounts, and/or the like. 
     If the expert  314  decides to answer a question (e.g., by selecting a question to answer from a list of questions assigned to the expert), an answer request  363  may be sent to the expert&#39;s client  318 . For example, the answer request  363  may include data such as question ID, question content, question priority, and/or the like, and may be in XML format substantially in the following form:

     The EXP server may analyze answer data  379  to convert the answer into an appropriate format (e.g., convert MPEG2 video format provided by the expert into H.264 video format), to determine whether the answer should be associated with additional topics and/or tags, and/or the like. For example, the answer data may include question ID, answer ID, answer format, topics, tags, and/or the like. 
     If the user selects an answer that the user is interested in viewing, the EXP server may provide an answer response  383 . The answer response may include data such as answer ID, answer content, answer rating, expert ID, and/or the like, and may be in XML format substantially in the following form: 
                                            &lt;XML&gt;                         &lt;AnswerResponse&gt;                         &lt;AnswerID&gt;ID_Answer1&lt;/AnswerID&gt;           &lt;AnswerContent&gt;expert’s answer&lt;/AnswerContent&gt;           &lt;AnswerRating&gt;4&lt;/AnswerRating&gt;           &lt;ExpertID&gt;ID_Expert1&lt;/ExpertID&gt;                         &lt;/AnswerResponse&gt;                         &lt;/XML&gt;                        
The answer may be output  387  to the user. For example, the client may play back the video-blog answer to the user.
 
       FIG. 4  shows a logic flow diagram illustrating an exemplary expert determining (ED) component in one embodiment of the EXP. In  FIG. 4 , a request to determine an expert for a question may be received at  401 . For example, the request to determine an expert for a question may be received via a C++ function call as a result of a user asking a new question. 
     One or more topics associated with the question may be determined at  405 . For example, the request to determine an expert for a question may include an identifier of the question, which may be utilized to retrieve the one or more topics associated with the question (e.g., from the questions data store  730   c ) via one or more SQL statements substantially in the following form:
         SELECT QuestionTopics   FROM Questions   WHERE QuestionID=“identifier of the question”       

     One or more tags associated with the question may be determined at  410 . For example, the identifier of the question may be utilized to retrieve the one or more tags associated with the question (e.g., from the questions data store  730   c ) via one or more SQL statements substantially in the following form:
         SELECT QuestionTags   FROM Questions   WHERE QuestionID=“identifier of the question”       

     One or more experts associated with the one or more topics and/or the tags may be determined at  415 . In one embodiment, experts may specify topics in which they consider themselves experts (e.g., upon signup with the EXP), and an expert who specifies a topic associated with the question may be examined to determine whether the expert is one of the best rated experts for the topic. In another embodiment, an expert identified by others (e.g., other experts) as an expert in a topic associated with the question may be examined to determine whether the expert is one of the best rated experts for the topic. In yet another embodiment, any EXP expert may be examined to determine whether the expert is one of the best rated experts for the topic. For example, experts associated with a topic may be determined (e.g., based on data from the users data store  730   a ) via one or more SQL statements substantially in the following form:
         SELECT UserID   FROM Users   WHERE (IsExpert=“TRUE”) AND (ExpertTopics=QuestionTopics)       

     A determination may be made at  420  whether there remain experts to examine (e.g., have the determined experts been examined). If there remain experts to examine, the next expert may be selected at  425 . For example, the next expert may be selected by iterating through the results of executing the SQL query. Information regarding the expert (e.g., information regarding the expert&#39;s established reputation, field of expertise, level of public engagement, social impact) may be obtained from a variety of source (e.g., obtained from the users data store  730   a  by retrieving data submitted by the expert; obtained by crawling the expert&#39;s LinkedIn profile, academic publications, Twitter stream, and/or the like; obtained by search through the expert&#39;s books via an online bookstore&#39;s API using keywords). 
     The expert&#39;s reputation value and/or weight may be determined at  430 . For example, the expert&#39;s position (e.g., the title of the position), the number and/or character of the expert&#39;s awards, peer reviews, media reviews, and/or the like may be utilized to determine the expert&#39;s reputation value. In one implementation, the expert&#39;s title may be associated with a specified point value (e.g., Assistant Professor may be associated with 1 point, Associate Professor may be associated with 2 points, Professor may be associated with 3 points). In another implementation, each award (e.g., that is relevant to the topic and/or tags associated with the question) may be associated with 1 point. For example, various point values associated with the expert&#39;s reputation may be summed to determine a reputation value for the expert (e.g., an Associate Professor with one relevant award may have a reputation value of 3 points). The expert&#39;s reputation value may have a weight (e.g., 25%) that specifies how much impact the expert&#39;s reputation value should have on the expert&#39;s overall rating. For example, the expert&#39;s reputation weight may be specified via a configuration parameter. 
     The expert&#39;s specific expertise value and/or weight may be determined at  435 . For example, the expert&#39;s field of research, the number and/or character of publications, the number of years spent in the field, committee memberships, activities, and/or the like may be utilized to determine the expert&#39;s specific expertise value with regard to the topic and/or tags associated with the question. In one implementation, the number of years that the expert spent in the field associated with the topic and/or tags may be associated with a specified point value (e.g., 1 point for each year spent in the field). In another implementation, each publication (e.g., that is relevant to the topic and/or tags associated with the question) may be associated with 1 point. For example, various point values associated with the expert&#39;s specific expertise may be summed to determine a specific expertise value for the expert (e.g., an expert with three years in the field and two relevant publications may have a specific expertise value of 5 points). The expert&#39;s specific expertise value may have a weight (e.g., 25%) that specifies how much impact the expert&#39;s specific expertise value should have on the expert&#39;s overall rating. For example, the expert&#39;s specific expertise weight may be specified via a configuration parameter. 
     The expert&#39;s public engagement value and/or weight may be determined at  440 . For example, the expert&#39;s interest in and/or track record of participating in public discourse, publishing books and/or other media (e.g., unrelated to the expert&#39;s area of expertise), giving speeches, and/or the like may be utilized to determine the expert&#39;s public engagement value. In one implementation, the expert&#39;s track record of participating in public discourse (e.g., low, medium, or high participation) may be associated with a specified point value (e.g., 1 point for low participation, 2 points for medium participation, 3 points for high participation). In another implementation, each speech (e.g., that is unrelated to the topic and/or tags associated with the question) may be associated with 0.5 points. For example, various point values associated with the expert&#39;s public engagement may be summed to determine a public engagement value for the expert (e.g., an expert with high participation who gave three speeches may have a public engagement value of 4.5 points). The expert&#39;s public engagement value may have a weight (e.g., 25%) that specifies how much impact the expert&#39;s public engagement value should have on the expert&#39;s overall rating. For example, the expert&#39;s public engagement weight may be specified via a configuration parameter. 
     The expert&#39;s social impact value and/or weight may be determined at  445 . For example, the expert&#39;s communication skills (e.g., reputation for explaining complex topics), originality, insight, general recognition, and/or the like may be utilized to determine the expert&#39;s social impact value. In one implementation, the expert&#39;s general recognition (e.g., low, medium, or high general recognition) may be associated with a specified point value (e.g., 1 point for low general recognition, 2 points for medium general recognition, 3 points for high general recognition). In another implementation, each TV and/or radio appearance may be associated with 1 point. For example, various point values associated with the expert&#39;s social impact may be summed to determine a social impact value for the expert (e.g., an expert with medium general recognition and one TV appearance may have a social impact value of 3 points). The expert&#39;s social impact value may have a weight (e.g., 25%) that specifies how much impact the expert&#39;s social impact value should have on the expert&#39;s overall rating. For example, the expert&#39;s social impact weight may be specified via a configuration parameter. 
     An overall rating may be calculated for the expert at  450 . In one embodiment, the expert&#39;s overall rating may be based on the expert&#39;s component values (e.g., reputation value, specific expertise value, public engagement value, social impact value) in accordance with their respective weights. For example, the expert&#39;s overall rating may be a weighted average of the expert&#39;s component values (e.g., 3*0.25+5*0.25+4.5*0.25+3*0.25=3.875 overall rating). In some embodiments, the EXP may not have available data to determine one or more component values for the expert. In one implementation, the EXP may use a default value (e.g., the average of component values of experts whose component values are known) for a missing component value. In another implementation, the EXP may adjust the weights associated with the component values to compensate for unknown data (e.g., if the expert&#39;s general reputation value and specific expertise value are known, but public engagement value and social impact value are not known, the EXP may assign 50% weight to each of general reputation value and specific expertise value, and 0% weight to each of public engagement value and social impact value). 
     If there are no more experts to examine, the desired number of experts may be determined at  460 . For example, the EXP may be configured to prompt the top five (e.g., best rated) experts to answer the question. In one implementation, the desired number of experts may be specified via a configuration parameter. The desired number of best rated (e.g., having the highest overall rating associated with the question) experts may be selected at  465  to provide answers. 
       FIG. 5  shows a logic flow diagram illustrating an exemplary answer obtaining (AO) component in one embodiment of the EXP. In  FIG. 5 , a request to obtain an answer from an expert may be received at  501 . For example, the expert may click a “Record” button on the EXP website to respond to a question. 
     A video recording of the answer may be obtained from the expert at  505 . In one embodiment, the expert may record the answer via a web browser (e.g., via an Adobe Flash plug-in, via a Microsoft Silverlight plug-in). In one implementation, the expert may preview the recorded answer and decide whether the expert is satisfied with the answer. If the expert is not satisfied with the answer, the expert may delete the answer and/or re-record the answer. In another embodiment, the expert may upload a prerecorded video of the answer. In some implementations, the answer may have a time limit (e.g., a minimum length, a maximum length). 
     A determination may be made at  510  whether post-processing should be performed on the obtained video. For example, whether post-processing should be performed may be specified in a configuration parameter. In another example, the expert may indicate whether post-processing should be performed. A variety of post-processing techniques may be used at  515  to perform post-processing. In one embodiment, post-processing techniques may be applied to the video stream. For example, the video stream may be scaled to a specified size and/or resolution (e.g., to ensure a common size and/or resolution for answers). In another embodiment, post-processing techniques may be applied to the audio stream. For example, the audio stream may be normalized (e.g., to ensure a common audio volume level for answers). 
     A determination may be made at  520  whether a background template should be added to the obtained video. For example, whether a background template should be added to the obtained video may be specified in a configuration parameter. In another example, the expert may indicate whether a background template should be added. If, a background template should be added to the obtained video, one or more relevant background templates may be determined at  523 . For example, a background template may provide a background for the video (e.g., a classroom background for an answer related to education, a library background for an answer related to literature). In another example, a background template may provide decorative elements (e.g., a decorative frame) for the video. In one embodiment, the relevant background templates may be determined based on a topic and/or a tag associated with the question and the answer. In one implementation, topics and/or tags may be associated with one or more background templates, and the relevant background template may be selected (e.g., from the backgrounds data store  730   g ) via one or more SQL statements substantially in the following form:
         SELECT BackgroundID   FROM Backgrounds   WHERE AssociatedTopic=“identifier of the topic associated with the question”
 
The desired background template may be added to the video at  527 . In one embodiment, the EXP may automatically select a background template to add to the answer (e.g., the relevant background template for the topic associated with the question). In another embodiment, the expert may be presented with an assortment of background templates (e.g., the relevant background templates for the topic associated with the question), and the expert may select a background template to add to the answer.
       

     A determination may be made at  530  whether related media and/or newscast style elements should be embedded into the answer. For example, whether related media and/or newscast style elements should be embedded into the obtained video may be specified in a configuration parameter. In another example, the expert may indicate whether related media and/or newscast style elements should be embedded. If related media and/or newscast style elements should be embedded, related media and/or newscast style elements may be identified at  533 . For example, related media may include images, sounds, videos, links, and/or the like. In another example, related newscast style elements may include news tickers, overlaying graphical elements (e.g., logos), overlaying text, and/or the like. In one embodiment, the related media and/or newscast style elements may be identified based on themes and/or concepts associated with the question and/or the answer. In one implementation, the answer may be transcribed into text and analyzed to determine keywords. The media and/or newscast style elements may be associated with keywords, and related media and/or newscast style elements may be identified (e.g., from the media data store  730   h ) via one or more SQL statements substantially in the following form:
         SELECT MediaID   FROM Media   WHERE Associated Keywords=“keywords associated with the answer”
 
The selected media and/or newscast style elements may be embedded into the video at  537 . In one embodiment, the expert may be presented with the identified related media and/or newscast style elements, and the expert may select media and/or newscast style elements to add to the answer (e.g., media and/or newscast style elements that may help the expert answer the question and/or provide additional information).
       

       FIG. 6  shows a logic flow diagram illustrating an exemplary answer sorting (AS) component in one embodiment of the EXP. In  FIG. 6 , a request to present a user with answers may be received at  601 . For example, the request to present a user with answers may specify the answers that should be sorted (e.g., as a list of answer identifiers). 
     A determination may be made at  605  whether there remain answers to examine (e.g., have the answers been examined). If there remain answers to examine, the next answer may be selected at  610 . For example, data regarding the answer may be retrieved (e.g., from the answers data store  730   d ) via one or more SQL statements substantially in the following form:
         SELECT *   FROM Answers   WHERE AnswerID=“identifier of the selected answer”       

     The answer&#39;s views value and/or weight may be determined at  615 . For example, an answer that was viewed by a large number of users may be considered to be more relevant than an answer that was viewed by a small number of users. In one implementation, the number of views may be associated with a specified point value (e.g., 1 point for every ten views). For example, an answer with ten views may have a views value of 1 point. In another example, an answer with twenty five views may have a views value of 2 points. The answer&#39;s views value may have a weight (e.g., 40%) that specifies how much impact the answer&#39;s views value should have on the answer&#39;s overall rating. For example, the answer&#39;s views value weight may be specified via a configuration parameter. 
     The answer&#39;s sharing value and/or weight may be determined at  620 . For example, an answer that was shared, liked, and/or the like by a large number of users may be considered to be more relevant than an answer that was shared, liked, and/or the like by a small number of users. In one implementation, the number of shares, likes, and/or the like may be associated with a specified point value (e.g., 1 point for every five shares, likes, and/or the like). For example, an answer with ten shares may have a sharing value of 2 points. In another example, an answer with seventeen shares may have a sharing value of 3 points. The answer&#39;s sharing value may have a weight (e.g., 30%) that specifies how much impact the answer&#39;s sharing value should have on the answer&#39;s overall rating. For example, the answer&#39;s sharing value weight may be specified via a configuration parameter. 
     The answer&#39;s age value and/or weight may be determined at  625 . For example, an answer that was provided a long time ago may be considered to be less relevant than an answer that was provided recently. In one implementation, the age of the answer may be associated with a specified point value (e.g., 3 points for answers provided within the last month, 2 points for answers provided within the last year, 3 points for answers provided within the last five years). For example, an answer provided six months ago may have an age value of 2 points. The answer&#39;s age value may have a weight (e.g., 30%) that specifies how much impact the answer&#39;s age value should have on the answer&#39;s overall rating. For example, the answer&#39;s age value weight may be specified via a configuration parameter. 
     An overall rating may be calculated for the answer at  630 . In one embodiment, the answer&#39;s overall rating may be based on the answer&#39;s component values (e.g., views value, sharing value, age value) in accordance with their respective weights. For example, the answer&#39;s overall rating may be a weighted average of the answer&#39;s component values. In some implementations, the answer&#39;s overall rating may depend on the user&#39;s personal preferences. For example, an answer by an expert may have a higher overall rating for a user who follows the expert than for a user who does not follow the expert. In another example, users may follow certain topics and/or tags, and an answer may have a higher overall rating for a user who follows a topic and/or a tag associated with the answer than for a user who does not. 
     If there are no more answers to examine, the desired number of answers may be determined at  640 . For example, the EXP may be configured to present any available answers to the user. In another example, the EXP may be configured to present a specified number of top (e.g., three) answers to the user. In one implementation, the desired number of answers may be specified via a configuration parameter. The desired number of best rated (e.g., having the highest overall rating) answers may be selected at  645  and presented (e.g., sorted, highlighted) to the user in accordance with their rating (e.g., higher rated answers may be shown on top, the highest rated answer may be highlighted) at  650 .
