We are happy to announce a first release of DBpedia Spotlight – Shedding Light on the Web of Documents.
The amount of data in the Linked Open Data cloud is steadily increasing. Interlinking text documents with this data enables the Web of Data to be used as background knowledge within document-oriented applications such as search and faceted browsing.
DBpedia Spotlight is a tool for annotating mentions of DBpedia resources in text, providing a solution for linking unstructured information sources to the Linked Open Data cloud through DBpedia. The DBpedia Spotlight Architecture is composed by the following modules:
Web Service, a RESTful Web API that exposes the functionality of annotating and/or disambiguating entities in text. The service returns XML, JSON or RDF.
Annotation Java / Scala API, exposing the underlying logic that performs the annotation/disambiguation.
Indexing Java / Scala API, executing the data processing necessary to enable the annotation/disambiguation algorithms used.
