A machine learning toolkit for processing natural language text, specializing in tokenization, sentence segmentation, and entity recognition.

Apache OpenNLP provides a robust Java library for common NLP tasks using Maximum Entropy and Perceptron-based machine learning. Developers use it to build production pipelines for named entity recognition (NER), part-of-speech tagging, and chunking. It includes pre-trained models for multiple languages (English, Spanish, German) and command-line tools for training custom models on domain-specific datasets.
