中文摘要： 数据空间技术是数据库管理技术的进一步发展，是当今信息异常丰富时代的必需。目前数据空间技术对语义查询的支持能力相对薄弱，缺乏对资源潜在用途等潜在要素的识别与应用。为此，本项目将针对数据空间中基于潜在要素的关联实体集搜索的关键技术进行研究，研究内容包括：研究适合于数据空间的多级别数据逻辑组织模型；研究数据空间中关联知识构建模型，为实体匹配提供指导依据；研究数据空间中基于潜在用途的关联实体集匹配策略，支持多种灵活的实体匹配方式。本项目的研发成果将为管理开放的数据资源提供良好的支持，达到提高资源利用率和工作效率的目的，具有广阔的前景。 我们对本领域的发展和本项目的研究内容进行了相关研究，在多级别数据逻辑组织模型、关联知识构建模型、关联实体集匹配策略等方面取得了相关研究成果。申请发明专利1项，在国际、国内学术会议和期刊发表论文10篇（含已录用待发表的论文3篇），被EI或ISTP检索收录5篇次，协助培养博士研究生2名和硕士研究生4名，邀请5名国内外学者来校讲学，派12人次参加了国内外学术会议。

英文摘要： Explosion of the amount of personal information has made the technique of dataspaces search become a hot topic. However, most previous work's ability to support semantic search is lower, also some potenital factors (e.g. potential roles of resources) are not identified and applied better. Therefore, in this project we will research the key techniques of relative entity set search based on potential factors in dataspaces. The research content includes: A multi-level data organization model for dataspaces will be presented; A relationship knowledge construction model will be researched, which can provide abundant knowledge for entity matching. Some strategies for relative entity set matching will be researched, which can support more flexible ways of entity matching. The result of the project will provide better support for managing open resources and facilitate higher usage rate of resources. We have made related studies on the development of the research field and the key techniques in the subject. We have achieved many research results in multi-level data organization model, relationship knowledge construction model, relative entity set matching strategy, etc. We have applied for 1 invention patent and have published 10 papers (including 3 papers having been accepted but not published) in international conferences, national conferences and journals, where 5 ones were indexed by EI or ISTP. We have helped to cultivate 2 PhD candidates and 4 graduate students through the subject. We have invited 5 foreign or domestic scholars for giving us lectures, and arranged 12 person-times for attending domestic or international conferences.
