研究方向
主要研究大数据的获取、融合、分析与处理。
主要贡献
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，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ACMTODS、VLDB Journal、IEEE TKDE、ACM Computing Survey上发表论文100余篇，论文被引用1800余次。
