English Semantic Metadata: Generic Relation Extraction

This module provides exhaustive extraction capabilities for all relations that involve at least one recognized entity (for example, Person, Company, TVShow, MedicalCondition, etc.).

While other events and facts extracted by Calais are predefined and usually pertain to a specific domain (e.g., Merger and Acquisition for the Business domain, MovieRelease for Entertainment news), Generic Relations attempt to recognize all Subject-Predicate-Object relationships without predefining their types.

Generic Relations is turned off by default; you can turn it on by including the parameter enableMetadataType as explained in the "Input Parameters" section.

To get Generic Relations results you must choose the RDF output option; results are not included in other output formats.
