The µ-TBL System

This is a comprehensive system for transformation-based learning. Train your part-of-speech taggers, unknown word guessers, NP-chunkers, dialogue act taggers, word sense disambiguators, etc. using this tool. Comes with compilers for building taggers in Prolog or Java (and soon also for Oz/Mozart.)

µ-TBL Light

This is a light version of the µ-TBL system. Motivation is mainly pedagogical.

Prolog Word Experts

Peewee Power! Great for word sense disambiguation, part of speech tagging, etc.

Oz/Mozart NLP Tools

Oz/Mozart is already a very interesting platform for NLP. I willl do my best to make it even more so. Here are my first attempts: a tagger tool, a text categorization package, a tokenizer, and a sentence splitter.

Spaghetti and HMMeatballs

A tiny implementation of Viterbi tagging using HMMs. Motivation is mainly pedagogical.

The XMPL Package

An attempt to implement XPath and XSLT in Prolog. Not finished.

Linguistic Instruments Grammar Laboratories

A suite of Macintosh programs for teaching grammar formalisms. Written together with Björn Beskow and Joakim Nivre.

Finite-State Funhouse

Amusing things you can do with Finite State Machines.

Finite-State Technology and Logic Programming (REGI)

An interpreter for Extended Regular Expressions.
