研究概况

主要研究大数据的获取、融合、分析与处理。在海量多源异构数据表示、获取、融合、检索四个方面取得了创新成果,提出了基于图结构的异构数据统一表示模型、错误自动纠正的实体获取方法、基于模糊匹配的多源异构数据融合算法、结构感知的即敲即得式检索方法,建立了一套海量多源异构数据融合与检索方法。

大数据时代带来了数据处理方法的诸多挑战,针对传统方法重视处理效率而相对忽视数据质量的问题,目前主要研究群体计算,通过人机融合的计算方式提高大数据环境下的计算性能。

在国际会议ACM SIGMOD、VLDB、IEEE ICDE、ACM SIGIR、ACM SIGKDD、WWW和国际期刊ACM TODS、VLDB Journal、IEEE TKDE、ACM Computing Survey上发表论文80余篇,论文被引用1600余次。2014年获得IEEE Early Career Award,2013年入选教育部新世纪人才支持计划、北京青年英才计划,2010年获得北京市优秀博士论文奖,2011年获得全国优秀博士学位论文提名奖。获得教育部自然科学奖二等奖一项,计算机学会自然科学奖二等奖一项。

奖励与荣誉
