I just switched the github repository for my NLP experiments to be a public repository. Git pull requests will be appreciated! The code and data is released under the AGPL version 3 license - if you improve the code I want you to share the improvements with me and others :-)
This is just experimental code but hopefully some people may find it useful. My latest changes involve trying to use DBPedia URIs as identifiers for entities detected in text. Simple stuff, but it is a start.
