It supports the most common NLP tasks, such as language detection, tokenization, sentence segmentation, part-of-speech tagging, named entity extraction, chunking, parsing and coreference resolution. These tasks are usually required to build more advanced text processing services.<ref>[http://opennlp.apache.org/index.html Apache OpenNLP Website]</ref><ref>[http://wiki.apache.org/incubator/OpenNLPProposal Apache OpenNLP Proposal]</ref>
