Many NLP tools are already freely available in the NLP research community. DKPro Core provides Apache UIMA components wrapping these tools (and some original tools) so they can be used interchangeably in UIMA processing pipelines. DKPro Core builds heavily on uimaFIT which allows for rapid and easy development of NLP processing pipelines, for wrapping existing tools and for creating original UIMA components. More ›

Various models covering different languages accompany the components.
Reading and writing various formats is just one line of code away.
Our typesystem is comprehensive, yet simple.
The original flavour. Use DKPro in your Java projects.
Create self-contained scripts using DKPro and Groovy!
Easily integrate DKPro into your python projects!
Many of the wrapped third-party components and the models used by them should be cited individually. We currently do not provide a comprehensive overview over citable publications. We encourage you to track down citable publications for these dependencies. However, you might find pointers to some relevant publications in the Model overview of the DKPro Core release you are using or in the JavaDoc of individual components.
Please cite DKPro Core itself as:

A comprehensive (but probably not complete) list of scientific publications citing DKPro Core can be found on Google Scholar.

This project was initiated by the Ubiquitous Knowledge Processing Lab (UKP) at the Technische Universität Darmstadt, Germany under the auspices of Prof. Iryna Gurevych. It is now jointly developed at UKP Lab (Technische Universität Darmstadt) and Language Technology Lab (Universität Duisburg-Essen), and other contributors. More ›
