The goals of the proposed LinkedHumanities project are to create and maintain data integration tools tailored to digital humanities collections in order to build a machine-readable "web of facts" about philosophy. The tools will interconnect structured digital representations of the humanities and leverage the created links to enrich the respective data repositories. Application testbeds include the Indiana Philosophy Ontology (InPhO) project and the Stanford Encyclopedia of Philosophy (SEP). The specific outcomes of this proposal will be (a) the implementation of a linking service between the InPhO ontology and other knowledge repositories such as DBPedia and Freebase; and (b) the population of the InPhO ontology by leveraging the previously created links to other data repositories. Most importantly, however, the data integration tools will be designed to also serve the needs of other digital humanities projects.
