Apache OpenNLP is a machine learning-based toolkit designed for the processing of natural language text. It enables users to manage NLP tasks, such as language detection, tokenization, sentence segmentation, part-of-speech tagging, named entity extraction, chunking, parsing, and coreference resolution, train and evaluate machine learning model, determine the command to use to execute Java virtual machine, detect that a punctuation character marks the end of a sentence or not, and undo the tokenization of training data for the tokenizer. Features include default feature generation, cross-validation, document categorizer, tag dictionary, lemmatizer, built-in evaluation, and name finder.
