public class OccurrenceExtractionOperation
extends Object

Use a semantic engine to extract the occurrences of semantic entities from the text content of a document. The semantic engine is assumed to accept an HTTP POST request on a fixed URL and synchronously return the result of the analysis as an RDF/XML graph in the body of the response. The label, type and context text snippet of each occurrence is then extracted by performing a configurable SPARQL query on the resulting RDF model loaded in a temporary RDF graph. This pattern should work for semantic engines such as:

• Stanbol from the project http://incubator.apache.org/stanbol
• OpenCalais (untested)
• Maybe more
