v0.5.0.2 ChangesJune 10, 2015
- removed upper vesion bounds on many dependencies.
v0.5.0.1 ChangesFebruary 20, 2015
- Updates for mobx-0.3's changes to use Lazy Text.
v0.5.0.0 ChangesOctober 21, 2014
Added chunk, chunkText, and chunkStr functions to NLP.Chunk to make it easier to experiment with the chunker.
Added a formatting function to show ChunkedSententences (NLP.Types.Tree.showChunkedSent) that formats chunks in bracket notation, eg:
chunkText tgr chk "The dog jumped over the reluctant cat." "[NP The/DT dog/NN] [VP jumped/VBD] [NP over/IN the/DT reluctant/JJ cat/NN] ./."
Notice that the features still need some tuning for the chunker.
Moved the AveragePerceptron module into a NLP.ML (Machine Learning) module.
Added the 'tags-since-dt' feature to the AveragePerceptronChunker features and retrained the Conll2000 models.
v0.4.0.0 ChangesOctober 14, 2014
Added phrasal chunking via an Averaged Perceptron Chunker, trained on the Conll 2000 corpus.
Added a POS tagger trained on the Conll 2000 corpus, because the Conll chunker relies on that tagset.
Set the Conll 2000 POS tagger to the defaultTagger. Note that the tagset is much smaller than the Brown tagset used by the previous defaultTagger. The Brown tagger is still available from NLP.POS.brownTagger.
v0.3.0.1 ChangesOctober 09, 2014
Bumped dependency on base to >= 4.6 (from >= 4) because of Text.Read.readMaybe. This drops support for HP2012, and requires GHC 7.6 or newer.
fixed lots of warnings and added documentation.
v0.3.0.0 ChangesOctober 09, 2014
Changed the Sentence and TaggedSentence data types to be actual tree structures with real types at the respective layers. ChunkedSentence and ChunkOr were also added to facilitate phrase and clause chunking.
Added a POS Tag data type for Brown corpus tags, and a Chunk type for Chunks as well (in the Brown module, but that's probably not the best place, given that the chunks have nothing to do with the actual Brown corpus.)
Updated the Parsec Examples to use the typed tags/chunks.
Regenerated the defaultTager, it uses the Brown tags now instead of RawTag.
v0.2.0.1 ChangesSeptember 18, 2014
I realized immediately after the 0.2.0.0 release that I broke the defaultTagger by adding the protectTerms function to the LiteralTagger. Things broke because (i) there are bugs in that functionality, which uses run-time assembled regexes, and (ii) the UnambiguousTagger used in the defaultTagger delegates to an instance of the LiteralTagger, which pulled in the (semi-broken) protectTerms function. This has been fixed by replacing the tokenizer when the LiteralTagger is used as an UnambiguousTagger -- the later tager doesn't need the functionality, and it should never have been used there anyway.
Added a bevy of tests to cover the above fix.
Added tests (currently breaking) that exercise the broken bits of the protectTerms function.
- Added support for expressing information extraciton patterns via Parsec.
- Misc. bug fixes.
