Open Calais Relevance Scores

Continuous relevance scores, which were supported by legacy Open Calais have been slightly modified; in the new Open Calais, relevance scores are expressed as discrete values (except for the company entity which is given both discrete and continuous relevance scores).

All extracted entities have an associated RelevanceInfo tag that indicates how centric the entity is to the containing document. The tag includes the relevance attribute, which defines a discrete relevance score.

A RelevanceInfo tag for an extracted person:

Relevancy_Scoring

Currently, the following relevance attribute values (discrete relevance scores) are supported:

Relevancy_Scoring_1

The RelevanceInfo tag for the company entity also includes the relevancecont attribute (a continuous relevance score).
