Darmstadt Knowledge Processing Software Repository (DKPro Core)
DKPro Core is a collection of Apache UIMA-based software components for Natural Language Processing (NLP). Many powerful NLP components are already freely available and new components are continuously developed and published. These components cover the whole spectrum of tasks in Language Technology. DKPro Core contains wrappers for third party tools as well as NLP components which are developed directly at the UKP Lab. DKPro Core offers such NLP components for a number of different application areas like linguistic preprocessing, information retrieval or semantic text analytics for English or German. DKPro Core is built on tools like uimaFIT, which allows a fast and simple development of NLP-pipelines.
DKPro Core is available with two license options: Apache Software License (ASL) Version 2 or GNU Public License Version 3, with the latter one containing additional components.
