Hi all,

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 application, a demonstration client (HTML/Javascript UI) that
allows users to enter/paste text into a Web browser and visualize the
resulting annotated text.
    * Web Service, a RESTful Web API that exposes the functionality of
annotating and/or disambiguating entities in text. The service returns XML,
    * 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.
