We are pleased to announce the release of

DKPro Core, version 1.5.0 (ASL & GPL)

a collection of interoperable software components for natural language processing (NLP) based on the Apache UIMA framework.

http://code.google.com/p/dkpro-core-asl
http://code.google.com/p/dkpro-core-gpl

The collection provides UIMA wrappers for many third-party NLP tools for language analysis tasks, such as segmentation, part-of-speech tagging, lemmatization, parsing, etc. for various languages. Via DKPro Core, these tools become interoperable, accessible through a uniform API, and convenient to use.

This release brings new modules to DKPro Core:

== New API modules ==

api.phonetics - Annotation types for the phonetic level
api.semantics - Annotation types for semantic information (semantic fields and semantic role labelling)

== New I/O modules ==

io.conll - Reader and writer for the CONLL 2006 format
io.tcf - Reader and writer for the CLARIN TCF format
io.tgrep - Writer for TGrep2 corpus files
io.tiger - Reader for the Tiger XML format

== New analysis modules ==

commonscodec - Phonetic transcription based on the Apache Commons Codec library
decompounding - Flexible set of components for decompounding, based on different splitting and ranking algorithms
mate-tools - Wrapper for the mate-tools suite
morpha - Wrapper for the morpha stemmer/lemmatizer
mstparser - Wrapper for the mstparser
sfst - New module for SFST-based morphological analyzers
umlautnormalizer - Normalizer for umlauts in German texts (ASL)

Further highlights in this release include:

- Added support for resolving models from remote repositories at runtime
- Added TypeCapabilities annotations declaring which annotations they consume and produce
- Added auto-generated XML descriptors for UIMA components (via uimafit-maven-plugin)
- Added support for ClearNLP Semantic Role Labelling
- Added support for GATE Hepple POS tagger
- Added support for OpenNLP parser and name finder
- Upgrade to Apache uimaFIT 2.0.0
- Upgrade to Apache UIMA 2.4.2
- Updated to ArkTweet-NLP 0.3.2
- Upgrade to ClearNLP 1.3.1
- Upgrade to CoreNLP 3.2.0
- Upgrade to GATE 7.1
- Upgrade to jweb1t 1.3.0
- Upgrade to LanguageTool 2.2
- Upgrade to Maltparser 1.7.2
- Upgrade to Mate-Tools anna 3.5
- Upgrade to OpenNLP 1.5.3

Some modules are no longer maintained and were not considered of use for the general public, e.g. the io.mmax2 module and the io.wsdl module. They have been retired and are not included in this release.

When upgrading, please mind that you should not mix different versions of DKPro Core components in your projects - they may not be compatible with each other.
