Refining Instance Coreferencing Results Using Belief Propagation

Abstract

Abstract. The problem of coreference resolution (finding individuals, which describe the same entity but have different URIs) is crucial when dealing with semantic data coming from different sources. Specific features of Semantic Web data (ontological constraints, data sparseness, varying quality of sources) are all significant for coreference resolution and must be exploited. In this paper we present a framework, which uses Dempster-Shafer belief propagation to capture these features and refine coreference resolution results produced by simpler string similarity techniques.

Evaluation of instance matching tools: The experience of OAEI

“…Several other datasets used by different researchers to evaluate their tools separately were collected within the RIDDLE repository. 5 These datasets have also been adapted to the semantic web standards and used to evaluate the instance matching algorithms in the semantic web domain: e.g., Cora was used in [10,13,14], while the Restaurants dataset from the RIDDLE repository was used by [15]. The advantage of reusing these is the possibility to compare with the techniques developed in the database community, despite the differences in the format of processed data.…”

“…12 The NYT repository includes three subsets describing different types of entities mentioned in the New York Times articles: people, organizations, and places. These three subsets were linked to three commonly used semantic web data repositories: DBpedia, 13 Freebase, 14 and Geonames. 15 These links were provided by the data publishers, which improved the gold standard quality (see Table 4).…”

Metodología para la integración basada en ontologías de información de bases de datos heterogéneas en el dominio hidrográfico

“…En este trabajo también se recogen las principales diferencias entre la forma de gestionar múltiples URI para un mismo recurso de CRS y la práctica emergente de utilizar la propiedad owl:sameAs para identificar URI duplicadas. (Nikolov et al, 2008) presentan un acercamiento que utiliza los mecanismos de propagación de creencias Dempster-Shafer para mejorar la calidad de la integración de datos, concretamente, la correferencia de individuos. Los autores utilizan esta técnica para refinar los resultados de la resolución de la correferencia producidos por las técnicas de similitud de strings.…”
