研究概況
研究方向：群體計算、海量異構數據融合與分析
主要研究大數據的獲取、融合、分析與處理。在海量多源異構數據表示、獲取、融合、檢索四個方面取得了創新成果,提出了基於圖結構的異構數據統一表示模型、錯誤自動糾正的實體獲取方法、基於模糊匹配的多源異構數據融合算法、結構感知的即敲即得式檢索方法,建立了一套海量多源異構數據融合與檢索方法。
大數據時代帶來了數據處理方法的諸多挑戰，針對傳統方法重視處理效率而相對忽視數據質量的問題，目前主要研究群體計算，通過人機融合的計算方式提高大數據環境下的計算性能。
在國際會議ACM SIGMOD、VLDB、IEEE ICDE、ACM SIGIR、ACM SIGKDD、WWW和國際期刊ACM TODS、VLDB Journal、IEEE TKDE、ACM Computing Survey上發表論文100餘篇，論文被引用1800餘次。2014年獲得IEEE Early Career Award，2013年入選教育部新世紀人才支持計畫、北京青年英才計畫，2010年獲得北京市優秀博士論文獎，2011年獲得全國優秀博士學位論文提名獎。獲得教育部自然科學獎二等獎一項，計算機學會自然科學獎二等獎一項。主持青年973項目，國家優秀青年基金，國家自然科學基金面上項目。
