Rupert Westenthaler updated STANBOL-1251:
-----------------------------------------
Description:
Implement an Enhancement Engine that uses POS tags to extract Noun and Verb
Phrases
In Stanbol POS annotations can be aligned to concepts of the OLIA ontology (see
documentation at [1] for detailed information). This alignment allows engines
to language independent determine the lexical categories of tokens in the text.
The Pos-Chunker Engine will use those lexical categories of tokens to extract
Noun and Verb phrases by using the following rules
### Noun Phrases
* start: noun, pronoun, determiners, adjectives
* continuation: nouns, adpositions, adjectives, punctations
* end: noun, pronoun, determiners, adjectives
* required: noun
### Verb Phrases
* start: verb, adverb
* continuation: verb, adverb, punctations
* end: verb, adverb
* required: verb
This engine will allow to configure the processed languages (e.g. to deactivate
it for languages where other chunker are available).
The EnhancementEngine ordering will be ServiceProperties.ORDERING_NLP_CHUNK
The current plan is to make this engine also available in the 0.12 branch
