语义Web上的一个对象很可能由不同的方用多个URI表示。对象相互引用是一个识别对象的“等效”URI的过程,以实现更好的数据Web。在本文中,我们提出了一个自举的方法在语义Web上的对象共指。对于一个对象URI,我们首先建立一个内核,该内核由来自相同、(逆)功能属性和(最大)基数的语义等价的URI组成,然后根据文本描述扩展内核(例如,标签和本地名称)。我们还提出了一个基于信任度的方法来排名的内核中的相关URI,以及一个基于相似性的方法来排名的URI在内核的扩展。我们实现了所提出的方法,称为ObjectCoref,在一个大规模的数据集,包含76万个URI收集的猎鹰搜索引擎,直到2008年。准确率,相对召回率和响应时间的评估证明了我们的方法的可行性。此外,我们提出的方法来调查流行的URI别名现象在当前的语义Web。
An object on the Semantic Web is likely to be denoted with several URIs by different parties. Object coreferencing is a process to identify “equivalent” URIs of objects for achieving a better Data Web. In this paper, we propose a bootstrapping approach for object coreferencing on the Semantic Web. For an object URI, we firstly establish a kernel that consists of semantically equivalent URIs from the same-as, (inverse) functional properties and (max-)cardinalities, and then extend the kernel with respect to the textual descriptions (e.g., labels and local names) of URIs. We also propose a trustworthiness-based method to rank the coreferent URIs in the kernel as well as a similarity-based method for ranking the URIs in the extension of the kernel. We implement the proposed approach, called ObjectCoref, on a large-scale dataset that contains 76 million URIs collected by the Falcons search engine until 2008. The evaluation on precision, relative recall and response time demonstrates the feasibility of our approach. Additionally, we apply the proposed approach to investigate the popularity of the URI alias phenomenon on the current Semantic Web.
