    Description

      Detected Named Entities are represented in the AnalyzedText content part by a Chunk with a NER_ANNOTATION. In addition NLP engines may (or may not) also add a PHRASE_ANNOTATION for the same Chunk. However the EntityLinking engines currently only consider PHRASE_ANNOTATION when looking for processable Chunks. Because of that they will not consider Named Entities in cases where NER engines do not provide PHRASE_ANNOTATIONs.

      Because especially chunks of NER_ANNOTATIONs are extremely useful for Entity Linking this issue will change the behavior so that Chunks with a NER_ANNOTATION are marked as processable in cases where Nouns are included as processable phrase type in the TextProcessingConfig of the EntityLinkingEngine.

      This depends somehow on STANBOL-1262, as without the 'old' processing of Chunks this would result in unintended merging of Noun Phrases and NER chunks.
