Here are a few possibilities from a survey I conducted about a year
ago for the HCRC in Edinburgh.  I've generally excluded corpora on the
grounds that they're not "tools".  The only thing I can personally
comment on is the Alvey system, and I have no relationship with any of
the sources mentioned.  (In other words, don't ask me or blame me!)

I swithered about posting this, but decided that it might be generally
interesting and also that it could be useful in that if anyone can
update the information, or suggest similar tools, I'd be very
interested.  I don't mind summarising responses if you don't mind
waiting.

1. The Alvey Natural Language Toolkit

Comprises a parser, a large grammar of English, a morphological
analyser and a lexicon.  I've used the grammar development environment
extensively and it works fine, although it's limited to close
relatives of GPSG.  Good for teaching if the classes are small.

parsers.

4. Morfogen

A rule compiler which allows development of a morphological analyser.
Also analysers developed using Morfogen for English, Spanish, French
and Turkish and finally Allomorf, a single-user compiler and analyser,
which works with a specified lexical entry format.

Apparently handles affixation, infixation, gemination, agglutination,
vowel harmony, and interleaved morphemes (as in Semitic languages).

5. DIMAP (Dictionary Maintenance Programs)

Based on the Merriam-Webster Concise Electronic Dictionary.  Allows
dictionary construction by extracting information from the full
lexicon and storing it in user-specified formats.

There are sample dictionaries which implement semantic nets,
HPSG-style lexicons, conceptual dependency dictionaries, Allen's
logical forms, and Melcuk's explanatory and combinatory dictionaries.

Fairly sophisticated interface; displays results on-screen using quite
standard syntax trees.

10.  The Linguistic DataBase (LDB)

The LDB is a database system developed by the TOSCA group at Nijmegen
University which allows linguists who are not experts in computing to
access syntactically analyzed corpora.  The data in the database
comprises syntactic analysis trees of contiguous utterances in a
natural-language text.  The package includes the Nijmegen Corpus, a
130,000 word collection of modern British English.
