Entity linking in media content and user comments: Connecting data to wikipedia and other knowledge bases

This paper presents an approach to entity linking in the domain of Social TV on two different knowledge bases: Wikipedia and our own ontology of media assets. We provide insights into the main challenges posed by this task, together with a description of different tools and related projects in the field. Since the system described is part of a platform intended for commercial exploitation, licensing issues are described in order to help small and medium-sized enterprises (SME) willing to develop systems for entity linking to take decisions on the best choice. The paper also presents information about business benefits of these technologies for both end users and companies. The approach described includes an evaluation of three different disambiguation methods and two different entity candidate selection processes.
