Criteria
Criteria is a common field shared by all of the pipeline elements.
It can be used to specify a javascript expression which can control the order in which entities extractors are applied to the ingested documents. The javascript expression can be setup to choose entities extractors, based on the content and metadata extracted so far in the pipeline.
For example, Infinit.e supports the Open Calais, and Salience extraction engines.
The criteria field is of most use with the following pipeline processing elements
- automated text extraction
- feature extraction
For more information about use of criteria, and for detailed examples see Automated text extraction, and Feature extraction.
