研究领域

数据库管理系统，数据安全与隐私保护；信息检索

研究概况

我长期从事与数据库相关的研究与开发工作，在纯XML数据库系统、异构数据的关键字检索、数据安全与隐私保护，以及新型数据库系统等方面取得了一系列研究成果，发表了高水平的学术论文。

在纯XML数据库系统这个研究方向上，我提出了XML数据的编码方法、语义缓存方法、结构和分支连接算法以及判断两棵XML文档树等价的“隐式条件同态”算法，有效地解决了XML数据的存储、查询求解和同态判断问题，构建了纯XML数据库系统查询处理和查询优化的整体框架。在异构数据的关键字检索这个研究方向上，我提出了异构数据的统一图模型，构建了异构数据关键字检索的索引机制和排序机制，有效解决了异构数据的融合与检索问题，形成了具有自动补全、模糊查找和即敲即得特征的关键字检索体系。同时，我和国外的研究人员一起合作，充分研究并掌握了列数据库需要解决的延迟实体化、块迭代、特定列的压缩和隐形连接等查询优化的关键技术，并正在研发大型列数据库产品HUABASE。

我的研究成果拓宽了数据库的研究领域，同时把数据库、数据挖掘和信息检索技术有机地融合在一起，不仅促进了学科方向的交叉与融合，而且引起了学术界的广泛关注。我发表的主要学术会议论文被引用的总次数超过180次，他引总次数超过130次。其中，发表在数据库领域的顶级国际会议ACM SIGMOD和ACM CIKM上的两篇论文在短短两年时间就被欧、美、澳大利亚、新加坡、日本和中国等10多个国家的学者引用80余次，其中被数据库领域的顶级国际会议ACM SIGMOD、VLDB、ICDE和EDBT及顶级国际期刊ACM TODS等引用40余次。这些学者主要来自于MIT、UIUC、DUKE、Wisconsin、Arizona State University、The Ohio State University、MPI和NUS等国际名校和著名的研究机构。
