Treat is a framework for natural language processing and computational linguistics in Ruby. It provides a common API for a number of gems and external libraries for document retrieval, parsing, annotation, and information extraction.
Current 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 for several languages (Stanford & Enju).
- Word inflectors, including stemmers, conjugators, declensors, and number inflection.
- Lexical resources (WordNet interface, several POS taggers for English, Stanford taggers for several languages).
- Language, date/time, topic words (LDA) and keyword (TF*IDF) extraction.
- Serialization of annotated entities to YAML, XML formats 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.
- Decision tree and multilayer perceptron classification (liblinear coming soon!)
