中文简介:
在文化遗产中,大量的虚拟藏品正在形成。此类集合包含源自多个源的异构元数据和词汇概念集。在电子文化演示器的上下文中,我们前面已经展示了通过关键字搜索和语义集群可以有效地探索此类虚拟集合。本文介绍了clioparia的设计原理,clioparia是一个开源系统,为可伸缩的语义图搜索提供了API。克利奥帕特里亚的搜索策略的使用通过一个现实的用例来说明:搜索“毕加索”。我们讨论了可伸缩图搜索的细节,所需的OWL推理功能,并说明为什么SPARQL查询不足以解决搜索问题。
课程简介: n cultural heritage, large virtual collections are coming into existence. Such collections contain heterogeneous sets of metadata and vocabulary concepts, originating from multiple sources. In the context of the E-Culture demonstrator we have shown earlier that such virtual collections can be effectively explored with keyword search and semantic clustering. In this paper we describe the design rationale of ClioPatria, an open-source system which provides APIs for scalable semantic graph search. The use of ClioPatria’s search strategies is illustrated with a realistic use case: searching for ”Picasso”. We discuss details of scalable graph search, the required OWL reasoning functionalities and show why SPARQL queries are insufficient for solving the search problem.
关 键 词: 虚拟集合; 搜索关键词; 语义聚类; 语义图搜索
