| The use of this component requires a API key from OpenCalais. Without providing an API key, the engine will not work. | |
| Such a key can be obtained from | |
| http://www.opencalais.com/APIkey | |
| In the OSGi configuration console the key can be set as value of the property | |
| org.apache.stanbol.enhancer.engines.opencalais.license | |
| Also, the tests require the API key. Without the key some tests will be skipped. For Maven the key can be set as a system property on the command line: | |
| mvn -Dorg.apache.stanbol.enhancer.engines.opencalais.license=YOUR_API_KEY [install|test] | |
| Configuration properties that influence the enhancements delivered from the engine at runtime are: | |
| - org.apache.stanbol.enhancer.engines.opencalais.typeMap | |
| The value is the name of a file for mapping the NER types from OpenCalais to other types. By default, a mapping to the DBPedia types is provided. If no mapping is desired one might pass an empty mapping file. | |
| - org.apache.stanbol.enhancer.engines.opencalais.NERonly | |
| A boolean property to specify whether in addition to the NER enhancements also the OpenCalais Linked Data references are included as entity references. By default, these are omitted. | |
