In particular, Collaborative Question Answering (CQA) model has emerged as a potential alternative to web search: participants post questions and answers, and rate and evaluate each other\u0027s contributions. The resulting archives of both the content and the context of the interactions provide a testbed for development of novel natural language processing, text mining, and information retrieval techniques. I will describe our new techniques for mining social media for tasks such as estimating content quality, contributor authority, and information seeker intent and satisfaction with the results. While the primary goal of this work is improving information access, I will also describe, if time permits, connections to medical informatics and public health research.\u003C\/p\u003E\n\u003Cp\u003E\u003C\/p\u003E\n\u003Cp\u003EBio:\u003C\/p\u003E\n\u003Cp\u003E\u003Ca href=\u0022http:\/\/www.mathcs.emory.edu\/~eugene\/\u0022\u003EDr. Eugene Agichtein\u003C\/a\u003E is an Assistant Professor in the Mathematics and Computer Science Department at Emory University where he directs the Intelligent InformationAccess laboratory. Eugene\u2019s research interests are in information retrieval, user modeling, text and data mining, and natural language processing. He received a Ph.D. from Columbia University in 2005, and a B.S. in Engineering from the Cooper Union in 1998.\u00a0 Previously, he was a Postdoctoral Researcher in the\u00a0 Text Mining, Search, and Navigation group at Microsoft Research, and a consulting researcher at Yahoo! Research. Eugene\u0027s work was recognized with a Microsoft \u201dBeyond Search\u201d award, Yahoo! faculty research award, and a SIGMOD 2006 best paper award.\u003C\/p\u003E\n\u003Cp\u003E\u003C\/p\u003E\n\u003Cp\u003E\n\u003C\/p\u003E\n\u003Cp\u003E~~~~~~~~~~~~~~~~~~\u003C\/p\u003E\n\u003Cp\u003E\u003C\/p\u003E\n\u003Cp class=\u0022MsoPlainText\u0022\u003EYou are cordially invited to attend a reception that will follow the seminar to chat informally with faculty and students.
