OpenNLP: Natural Language Processing

An open-source Java library for NLP tasks like tokenization, POS tagging, named entity recognition, and more, used in building text analysis applications.

What is OpenNLP?

OpenNLP is an open-source Java library for natural language processing (NLP). It provides a wide range of NLP tasks, allowing developers to build applications that can understand and analyze text.

Some of the key features and capabilities of OpenNLP include:

  • Tokenization - splitting text into words, punctuation marks, etc.
  • Part-of-speech tagging - labeling words with their grammatical roles like noun, verb, adjective
  • Named entity recognition - identifying entities like people, organizations, locations
  • Chunking - detecting key phrases within sentences
  • Parsing - analyzing sentence structure and relationships
  • Coreference resolution - linking pronouns to the entities they refer to
  • Language detection - automatically detecting the language of text

OpenNLP provides pre-built statistical models for performing the above tasks in many major languages like English, French, German, and Spanish. Developers can use these models right away or even train their own custom models.

Overall, OpenNLP offers an extensive set of natural language processing capabilities for building NLP applications like chatbots, recommendation engines, content analyzers, and more.
