Apache OpenNLP

Apache OpenNLP is a machine learning-based toolkit for processing natural language text. It provides a comprehensive set of tools for building natural language processing (NLP) pipelines, supporting tasks such as tokenization, sentence segmentation, part-of-speech tagging, named entity recognition, parsing, and coreference resolution. Designed for extensibility and performance, OpenNLP is suitable for both research and production environments.
