DKPro Core 1.1.0 Open Source Release
2011/02/11

We are pleased to announce the release of DKPro Core 1.1.0 – a collection of software components for natural language processing (NLP) based on the . Apache UIMA framework
DKPro Core consists of a number of pre-processing components for NLP tasks, often wrapping existing libraries or tools for easy use in an UIMA pipeline.
- tokenization/segmentation
- compound splitting (Banana Split, JWordSplitter)
- stemming (Snowball)
- part-of-speech tagging (TreeTagger)
- parsing (Stanford Parser)
- language identification (TextCat)
- spelling correction (Jazzy)
- IO support for various data types (text, XML, PDF, WSDL, Wikipedia, …)
A basic UIMA type system is provided with which all of the components work out-of-the-box. Some components can be configured for use with other type systems.
DKPro Core builds heavily on , making use of features such as injection of configuration parameters and automatic type detection. Because using DKPro in Java code with uimaFIT is so easy, we do not provide traditional UIMA XML descriptors for our analysis engines, readers and consumers – only for the type systems. uimaFIT
We offer two sets of components with DKPro Core:
- provides components under the Apache Software License 2.0 DKPro Core ASL
- provides components under the GNU Public License 3.0 DKPro Core GPL
Currently DKPro Core is meant to be used with . We host a Apache Maven containing DKPro Core ASL, DKPro Core GPL and all their dependendies. You can also obtain JARs for individual components from that repository. With future releases of DKPro, we may add the option of a downloadable archive. public Maven repository
This project was initiated by the Ubiquitous Knowledge Processing Lab (UKP) at the Technische Universität Darmstadt, Germany under the auspices of Prof. Dr. Iryna Gurevych. All former and current member of the UKP Lab have contributed in code, as testers or in spirit to this project. It constitutes an essential cornerstone for our research environment at the UKP Lab.
DKPro Core requires Java 1.6, UIMA 2.3.1 and uimaFIT 1.1.0 (amongst other component-specific dependencies).
