主要研究方向
主要從事自然語言處理、人工智能及相關的研究，内容涉及大規模語言知識獲取和語義分析技術、自動問答和人機對話、觀點挖掘等。
研究成果概況
在包括ACL，EMNLP，COLING，ICML，IJCAI，AAAI，SIGIR，KDD等國際會議和Computational Linguistics，TALIPS等期刊發表學術論文，共發表學術論文60多篇。
承擔過多項10餘項國家項目，包括國家863項目“大規模中文語義信息處理技術與系統”（2012.1-2014.12）的首席專家，國家社科基金重大項目“面向網絡文本的多視角語義分析方法、語言知識庫及平台建設研究”（2013.1-2017.12）的首席專家。
構建的語言資源庫轉讓給多家企業或研究機構。目前為中文信息學會的常務理事。
