Disaster (DISAmbiguator and STatistical chunkER) is a Python module for chunking and morphosyntactic disambiguation. The module is being developed, currently the following functionality is available:

• corpus I/O routines, including the XCES format (IPI PAN dialect) and simple extension to handle IOB chunk tags,
• graphical chunk editor,
• rudimentary curses-based morphosyntactic annotation editor (allows to alter disambs in tags, no possibility to add new tags),
• re-implementatino of the TaKIPI tagger with customisable tagset,
• re-implementation of the JOSKIPI formalism with customisable tagset and possibility of references to chunk annotations,
• several simple chunking algorithms, including Christer Johansson's memory based chunker

The software package has been released under GNU GPL 3.0, available here.
