Techopedia Explains Open Calais

Open Calais is a web service provided by Reuters for automatically attaching rich semantic data into documents and other content submitted by users. It employs natural language processing (NLP) and machine learning algorithms, which were trained by Reuters’ editorial teams for years, to process data and extract the relevant semantic information.

On an average it takes the API under one second to process a sizable news article. The information gathered is then sent back as JSON, N3 or in Resource Description Framework (RDF) where results are grouped: identifying entities, facts, topics and events within the text. It also offers contextual navigation, more focused news and even hidden relevant facts and events within submitted texts.

The product’s initiative is to integrate interoperability of content and advance the company mission to deliver intelligent information.
