Rupert Westenthaler created STANBOL-1266:
--------------------------------------------
Summary: EntityLinking engines should consider Chunks with NER
annotations
Key: STANBOL-1266
URL: https://issues.apache.org/jira/browse/STANBOL-1266
Project: Stanbol
Issue Type: Improvement
Components: Enhancement Engines
Affects Versions: 0.12.0
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
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.
