Section: Application Domains
Semantic metadata are at the core of the applications we have been working on for several years. These three last years, we have switched from semantic annotations of documents to interlinking problems between individual references in annotations of documents. The main linkage problem in our current ANR project Qualinca (see Section 8.1 ) consists of identifying an authority (i.e., an element of a referential described by metadata) in a bibliographic notice (i.e., metadata describing a document). This problem is an instance of the intensively studied reference resolution problem. In the Semantic Web, it can be recast as the computation of OWL:sameAs links between two metadata bases, clearly a fundamental problem for the Linked Open Data. We use a knowledge-based approach to solve this problem, and this year we have especially studied key notions for building rules that conclude on coreference or difference links between entities.
