I'm a LISP newbie. I've read that LISP is good for NLP. One paper
mentioned the use of s-expressions (containing a parse tree and a word
list) that pass through weighted rules which "fire" when the rule is
satisfied. For example, a certain rule might fire if "you" and "are"
are both present in the noun phrase of a sentence. From what I gather,
such an architecture is advantageous, because the training of the NLP
system is isolated to "tweaking" the rule set. Am I correct?
Is there any recommended treatise on NLP? Tools? Is LISP essential?
Are PERL regular expressions enough? Is there an English parser that
could cut up sentences into pieces and tag them with things like Noun
Phrase, Verb Phrase etc?
Thank You,
Deepak Gupta

"Natural language understanding" 2nd Ed., James Allen,
1994 Addison-Wesley, ISBN 0-8053-0334-0 (Hardback)
is excellent (although it probably goes much further
than you wished to go) and it is accompanied by
Common Lisp programs downloadable from some site.
