The Alvey Natural Language Tools
The UK Alvey Programme originally funded three projects at the Universities of
Cambridge, Edinburgh and Lancaster to provide tools for use in natural
language processing research. The DTI and SERC funded their continued support
and enhancement. The tools, a morphological analyser,
parsers, and a grammar and
lexicon (click on the components to find published
references to them), are usable individually as well as
together - integrated by a grammar development
environment - forming a complete system for the morphological,
syntactic and semantic analysis of a considerable subset of English.

The following information is available on-line:
The latest release of the ANLT is release 4. If you have paid for release 3 or
an upgrade to release 3, you are entitled to FTP release 4 at no extra
charge; see the FTP
instructions and use the same decryption key as you were given for
There will be further releases of ANLT integrating some of the recent
work described in the references. If you hold an ANLT licence and wish
to be informed directly about these releases, please check the list of
known licence holders and contact information
and send email if this is
inaccurate, incomplete or outdated.
Here is some technical
information on release 4 that has been added since the release date.
