Daniel Thanks for the comments. I have tried Prolog too, but didn't get very far. I am hoping to deal with pretty arbitrary inputs (typically news stories from internet newspapers etc), but initially just searching for key words and phrases. So far I have used PP to construct a pretty good tokeniser to identify words, sentences, punctuation etc, which was not very difficult. It may be that I won't get very far, but I'm retired and I do this for fun, so what the heck.

I have used Prolog DCGs to mess around with this kind of thing, and if you have a lot of control over the input and your expectations you can make progress with a tool for formal languages, but if you want to do something sophisticated or support arbitrary inputs, you're probably wasting your time. -- Daniel Lyons
