Rupert Westenthaler created STANBOL-1013:
--------------------------------------------
Summary: Seperate (Entity)Spotting and (Entity)Linking
Key: STANBOL-1013
URL: https://issues.apache.org/jira/browse/STANBOL-1013
Project: Stanbol
Issue Type: Bug
Components: Engine - Entity Linking, Enhancer
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Currently the EntityLinking engine performs two major tasks
(1) Spotting: detect the words in the analyzed Text that should be linked to
the controlled Vocabulary. For that words are categorized as "linkable",
"matchable" and "others". Also Chunks are considered for this task.
(2) Linking: Creates searches for "linkable" words while considering
"matchable" words. Labels of suggested Entities are tokenized and matched
against "linkable" and "matchable" words in the text. The
EntityLinkingConfiguration ise used to configure this task.
See the documentation of the EntityLinkingEngine [1] for details.
(1) is configured by using the TextProcessingConfiguration and implemented by
the ProcessingState class. (2) is configured by the EntityLinkingConfiguration
and implemented by the EntityLinker class.
Proposed Workplan:
=====
1. clean-up and improve the internal APIs used by the EntityLinking engine
2. define a public API for describing Entity Spotting results: Possibilities
include
* using the metadata of the ContentItems (e.g. fise:TextAnnotations)
* annotations in the AnalyzedText contentpart
* some additional ContentPart
3 Split-up (1) and (2) as two separate EnhancementEngines so that
* (1) NlpSpottingEngine: Spots potential Entities by using NLP processing
results
* (2) EntityLinkingEngine: Links Entities of a Controlled Vocabulary based
on Spotting results
4. Integrate Named Entity Linking into the new Spotting & Linking workflow
* By allowing Spotters to also annotate spotted Entities to carry
additional metadata (e.g. the type as suggested by NER)
* Extending the EntityLinkingEngine to make use of those metadata when
searching/matching Entities from linked Vocabularies.
