**Warning: This gem is unmaintained.** Treat is a toolkit for natural language processing and computational linguistics in Ruby. The Treat project aims to build a language- and algorithm- agnostic NLP framework for Ruby with support for tasks such as document retrieval, text chunking, segmentation and tokenization, natural language parsing, part-of-speech tagging, keyword extraction and named entity recognition. Learn more by taking a [quick tour](https://github.com/louismullie/treat/wiki/Quick-Tour) or by reading the [manual](https://github.com/louismullie/treat/wiki/Manual). **Features** * Text extractors for PDF, HTML, XML, Word, AbiWord, OpenOffice and image formats (Ocropus). * Text chunkers, sentence segmenters, tokenizers, and parsers (Stanford & Enju). * Lexical resources (WordNet interface, several POS taggers for English). * Language, date/time, topic words (LDA) and keyword (TF*IDF) extraction. * Word inflectors, including stemmers, conjugators, declensors, and number inflection. * Serialization of annotated entities to YAML, XML or to MongoDB. * Visualization in ASCII tree, directed graph (DOT) and tag-bracketed (standoff) formats. * Linguistic resources, including language detection and tag alignments for several treebanks. * Machine learning (decision tree, multilayer perceptron, LIBLINEAR, LIBSVM). * Text retrieval with indexation and full-text search (Ferret). **Contributing** I am actively seeking developers that can help maintain and expand this project.
