xtas, the eXtensible Text Analysis Suite
========================================

xtas is a collection of natural language processing and text mining tools,
brought together in a single software package
with built-in distributed computing
and support for the Elasticsearch document store.

xtas functionality consists partly of wrappers for existing packages,
with automatic installation of software and data;
and partly of custom-built modules coming out of research.
Currently offered are various parsers for Dutch and English
(Alpino, CoreNLP, Frog, Semafor),
named entity recognizers (Frog, Stanford and custom-built ones),
a temporal expression tagger (Heideltime)
and a sentiment tagger based on SentiWords.

A basic installation of xtas works like a Python module.
Built-in package management and a simple, uniform interface
take away the hassle of installing, configuring and using
many existing NLP tools.

xtas's open architecture makes it possible to include custom code,
run this in a distributed fashion and have it communicate with Elasticsearch
to provide document storage and retrieval.
See :ref:`extending` for details.
