DBpedia spotlight

TLDR

Interlinking text documents with Linked Open Data enables the Web of Data to serve as background knowledge for document‑oriented applications such as search and faceted browsing. The authors developed DBpedia Spotlight to automatically annotate text documents with DBpedia URIs, linking the Web of Documents to the Web of Data. DBpedia Spotlight lets users configure annotations via the DBpedia Ontology and quality metrics (prominence, topical pertinence, contextual ambiguity, disambiguation confidence) and is evaluated against three baselines and six public annotation systems, showing competitive performance. The system is open source, deployed as a freely available Web Service, and demonstrates competitiveness with state‑of‑the‑art disambiguation approaches.

Abstract

Interlinking text documents with Linked Open Data enables the Web of Data to be used as background knowledge within document-oriented applications such as search and faceted browsing. As a step towards interconnecting the Web of Documents with the Web of Data, we developed DBpedia Spotlight, a system for automatically annotating text documents with DBpedia URIs. DBpedia Spotlight allows users to configure the annotations to their specific needs through the DBpedia Ontology and quality measures such as prominence, topical pertinence, contextual ambiguity and disambiguation confidence. We compare our approach with the state of the art in disambiguation, and evaluate our results in light of three baselines and six publicly available annotation systems, demonstrating the competitiveness of our system. DBpedia Spotlight is shared as open source and deployed as a Web Service freely available for public use.
