ClearForest is a Thomson Reuters company in Tel Aviv, Israel that produces OneCalais solutions, which "use Natural Language Processing (NLP), text analytics and data mining technologies to derive meaning from unstructured information, including news articles, blog posts, research reports and more." OneCalais carries out the following functions:
- It categorizes each piece of content using both IPTC news codes and social tags.
- It identifies and tags the people, places, companies, facts and events in content, and returns those tags in the official W3C Semantic Web specification for metadata, Resource Description Framework (RDF).
- It returns a unique document identifier, as well as links to related assets in the Linking Open Data (LOD) cloud.
ClearForest also produces the free OpenCalais service, which produces semantic metadata for content submitted by users. Users submit unstructured documents (text/HTML/XML) into OpenCalais, and the system tags named entities, facts, and events within the document. The OpenCalais web service is free to both commercial and non-commercial users.
