In particular, the Community Question Answering (CQA) model has evolved as an effective alternative to web search:\u003C\/p\u003E\n\u003Cp\u003Eusers post questions and answers, and rate and evaluate each other\u2019s content. As a result, users contribute both content and rich interaction metadata in their roles as askers, answerers, and evaluators. To give a sense of the scale, just one popular site, Yahoo! Answers, has attracted an active participation of millions of users who contributed hundreds of millions of answers to tens of millions of questions - providing a goldmine of data about user information needs, interactions, and judgments. The talk with describe what we can learn from all of this data, including estimating content quality, contributor authority, user intent, and asker satisfaction with the results.\u003C\/p\u003E\n\u003Cp\u003EFor more information please contact \u003Ca href=\u0022mailto:zha@cc.gatech.edu\u0022\u003EDr. Hongyuan Zha\u003C\/a\u003E\u003C\/p\u003E\n\u003Cp\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"27154","created_gmt":"2010-02-11 15:56:39","changed_gmt":"2016-10-08 01:49:56","author":"Louise Russo","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-11-14T10:00:00-05:00","event_time_end":"2008-11-14T11:00:00-05:00","event_time_end_last":"2008-11-14T11:00:00-05:00","gmt_time_start":"2008-11-14 15:00:00","gmt_time_end":"2008-11-14 16:00:00","gmt_time_end_last":"2008-11-14 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"47223","name":"College of Computing"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"Lometa Mitchell","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
