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 retrieval with indexation and full-text search (Ferret).
 * Text chunkers, sentence segmenters, tokenizers, and parsers (Stanford & Enju).
-* Word inflectors, including stemmers, conjugators, declensors, and number inflection.
 * 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, linear, support vector machines).
+* Machine learning (decision tree, multilayer perceptron, LIBLINEAR, LIBSVM).
+* Text retrieval with indexation and full-text search (Ferret).
