OpenNLP English Pipeline
The English tokeniser, sentence splitter, POS tagger, phrase chunker and named-entity recogniser from Apache OpenNLP. The components are based on the maxent machine learning algorithm, and produce Token and Sentence annotations in a form compatible with other standard GATE tools.
|:Person||Standard named entity types|
|Additional annotations available if selected|
|:Percentage||Expressions representing percentages|
|:Sentence||Sentences detected by the sentence splitter|
|:Token||The individual tokens of the text, with "category" feature for POS and "chunk" feature for for the I/O/B-style chunk tags. Complete chunks derived from the tags are also available as their respective annotation types (e.g. a sequence of tokens tagged B-NP, I-NP, I-NP gives rise to an "NP" annotation spanning the sequence).|
