主要研究方向

主要从事自然语言处理、人工智能及相关的研究，内容涉及大规模语言知识获取和语义分析技术、自动问答和人机对话、观点挖掘等。

研究成果概况

在包括ACL，EMNLP，COLING，ICML，IJCAI，AAAI，SIGIR，KDD等国际会议和Computational Linguistics，TALIPS等期刊发表学术论文，共发表学术论文60多篇。

承担过多项10余项国家项目，包括国家863项目“大规模中文语义信息处理技术与系统”（2012.1-2014.12）的首席专家，国家社科基金重大项目“面向网络文本的多视角语义分析方法、语言知识库及平台建设研究”（2013.1-2017.12）的首席专家。

构建的语言资源库转让给多家企业或研究机构。目前为中文信息学会的常务理事。
