Abstract
Enriching knowledge bases with multimedia information makes
it possible to complement textual descriptions with visual
and audio information. Such complementary information
can help users to understand the meaning of assertions, and
in general improve the user experience with the knowledge
base. In this paper we address the problem of how to enrich
ontology instances with candidate images retrieved from
existing Web search engines. DBpedia has evolved into a
major hub in the Linked Data cloud, interconnecting millions
of entities organized under a consistent ontology. Our
approach taps into the Wikipedia corpus to gather context
information for DBpedia instances and takes advantage of
image tagging information when this is available to calculate semantic relatedness between instances and candidate images. We performed experiments with focus on the particularly challenging problem of highly ambiguous names. Both methods presented in this work outperformed the baseline. Our best method leveraged context words from Wikipedia,tags from Flickr and type information from DBpedia to achieve an average precision of 80%.
