Automatic Expansion of DBpedia Exploiting Wikipedia Cross-Language Information - scientific work related to Wikipedia quality published in 2013, written by Alessio Palmero Aprosio, Alessio Palmero Aprosio, Claudio Giuliano and Alberto Lavelli.

Overview

DBpedia is a project aiming to represent Wikipedia content in RDF triples. It plays a central role in the Semantic Web, due to the large and growing number of resources linked to it. Nowadays, only 1.7M Wikipedia pages are deeply classified in the DBpedia ontology, although the English Wikipedia contains almost 4M pages, showing a clear problem of coverage. In other languages (like French and Spanish) this coverage is even lower. The objective of this paper is to define a methodology to increase the coverage of DBpedia in different languages. The major problems that authors have to solve concern the high number of classes involved in the DBpedia ontology and the lack of coverage for some classes in certain languages. In order to deal with these problems, authors first extend the population of the classes for the different languages by connecting the corresponding Wikipedia pages through cross-language links. Then, authors train a supervised classifier using this extended set as training data. Authors evaluated system using a manually annotated test set, demonstrating that approach can add more than 1M new entities to DBpedia with high precision (90%) and recall (50%). The resulting resource is available through a SPARQL endpoint and a downloadable package.
