Language Processing with Perl and Prolog: Theories, Implementation, and Application (Cognitive Technologies): Pierre M. Nugues: 9783642414633: Amazon.com: Books

While I still need to examine this area in more depth, this book seems to have the key elements needed to start working. The fact that it is using Perl and Prolog is not a big deal since the key points of the code examples are sufficiently explained to port it to whatever language you might want to use.
