Abstract

DBpedia exposes data from Wikipedia as machine-readable Linked Data. The DBpedia data extraction process generates RDF data in two ways; (a) using the mappings that map the data from Wikipedia infoboxes to the DBpedia ontology and other vocabularies, and (b) using infobox-properties, i.e., properties that are not defined in the DBpedia ontology but are auto-generated using the infobox attribute-value pairs. The work presented in this paper inspects the quality issues of the properties used in the Spanish DBpedia dataset according to conciseness, consistency, syntactic validity, and semantic accuracy quality dimensions. The main contribution of the paper is the identification of quality issues in the Spanish DBpedia and the possible causes of their existence. The findings presented in this paper can be used as feedback to improve the DBpedia extraction process in order to eliminate such quality issues from DBpedia.

    In these cases, the infobox label contains a slash. For example, the label ‘idoma/s’ generates a property ‘http://es.dbpedia.org/property/idioma/s’.
