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.

 Java interface to the OpenCalais API, using the REST API invocation and JSON outputFormat for low overhead.

thea_opencalais is a Prolog wrapper for accessing Open Calais and process the results. It is an application of Thea Prolog library for OWL2 Ontologies. thea_opencalais uses the Open Calais ontology and parses the service response first into Ontology axioms and finally into prolog terms and predicates, accessible from within a Prolog program.

Philippe Adjiman has created this high-quality video tutorial that demonstrates how to make calls to OpenCalais from Java code. In only four minutes you can see how to make those calls.

A demonstration of using OpenCalais with PHP code.

This sample code shows how to use Markup entities and Disambiguated entities and how to use the Linked Data to get additional info on entities (how to retrieve information from the Linked Data end point).

Basically, the code sends a document to OpenCalais with RDF output format, and then analyzes the Companies, Geographies, Products, marked-up Companies, and the relevant disambiguated company URIs in the Linked Data. It outputs an xml file containing simplified data gathered from OpenCalais and Linked Data.

The application sends a document to OpenCalais with RDF output format. It analyzes the entities and outputs an xml file containing simplified data gathered from OpenCalais and Linked Data.

I have written a small tutorial showing how to use features from the 3.1 release of the Calais service to geotag a text and display the identified locations on a map. The tutorial can be found on my web site and a running version of the demo application is here.
