Abstract

Abstract: Semantic Web data proliferates with the rapid growth of the semantic Web. An object on the semantic Web is likely to be denoted with many identifiers (e.g., URIs) by different parties. Resolving an object coreference on the semantic Web is to identify different identifiers for the same object and eliminate the inconsistency between their involved RDF (resource description framework) data, which is important for semantic Web data fusion, search, browsing, etc. In this paper, the problem of resolving object coreference on the semantic Web is first formalized. Next, the state of the art of works are surveyed and categorized into five aspects: The used characteristics for coreference identification, the mechanisms for data conflict resolution, the applicable scopes of current approaches, prototypes, and benchmarks. Finally, open research issues are discussed and possible future research directions are also pointed out. Key words: object coreference; coreference resolution; instance matching; semantic Web; data fusion 摘 要: 随着语义Web的快速发展,语义Web数据大幅增长.在语义Web中,单个对象很可能由多个不同的标识符 (例如URI)指称.语义Web中,对象共指的消解是识别语义Web中指称相同对象的不同标识符,并消除描述这些标识
