The Department of Linguistics of the University of Melbourne has just
launched its home page on:

(URL:http://adhocalypse.arts.unimelb.edu.au/Dept/Linguistics/home.html)

The home page currently includes the contents of the Departmental handbook,
and a summary of research within the department. Pending space availability,
we may also be placing papers written in the department on-line.

I would like to announce the construction of the Indo-European Homepage
located at:

http://www.rz.uni-frankfurt.de/home/ftp/pub/titus/public_html

It will function as a central web site for access to resources
of relevance to Comparatists, Indo-Europeanists and other interested
scholars.

Announcing...

New natural language parsing software from SIL (Summer Institute of
Linguistics:

 * PC-KIMMO version 2 -- a morphological parser

 * Englex version 2 -- a morphological description of English

 * PC-PATR -- a syntactic parser

 * PC-PARSE -- a new mailing list devoted to SIL parsing software

All of this software is available for MS-DOS, Windows, Macintosh, and
UNIX. All software and documentation are copyrighted "freeware": they
can be used and redistributed at no charge, but cannot be resold or
used in commercial products without permission from SIL.

This software is still in prerelease status and will likely continue
to be updated. For the latest information on the software (including
on-line documentation, connect to our servers at these URLs:

Gopher: gopher://gopher.sil.org/
FTP: ftp://ftp.sil.org/

 PC-KIMMO version 2
 ------------------

PC-KIMMO is a morphological parser based on Kimmo Koskenniemi's
two-level model of morphology. It was first released by SIL (Summer
Institute of Linguistics) in 1990. Version 2 (beta) is now available.
New features include the following:

 --The rules component supports multigraphs.

 --The rules component can read a rules file produced by Xerox's TWOLC
 rule compiler.

 --Lexical entries have a new, more flexible encoding format.

 --Lexical entries permit a features field.

 --A word grammar component has been added.

 --The recognizer returns full parse trees and feature structures.

 --A Windows version is available (command-line interface only, but uses
 Windows memory management).

Of these new features, the word grammar component is the most
significant. The word grammar component uses a unification-based parser
based on the PATR-II formalism described by Stuart M. Shieber in "An
Introduction to Unification- based Approaches to Grammar (CSLI, 1986).
The word grammar produces output such as this tree and feature
structure for the word "enlargement":

 Word
 |
 Stem
 _____|______
 Stem SUFFIX
 ___|____ +ment
 PREFIX Stem
 en+ |
 ROOT
 `large

 Word:
 [ head: [ number:SG
 pos: N ]
 lemma: `large
 lemma_pos:AJ ]

Note that the feature structure reports the part-of-speech (pos) of the
word (something not possible with PC-KIMMO version 1). Thus one new use
of PC-KIMMO is part-of-speech tagging.

 Englex -- a morphological description of English
 ------------------------------------------------

Englex was first released for PC-KIMMO version 1. It has now been
revised and updated to work with PC-KIMMO version 2 (as well as
PC-PATR--see below). The lexicon files have been converted to the new
format, and a word grammar has been added.

 PC-PATR -- a syntactic parser
 -----------------------------

PC-PATR is a syntactic parser that uses the same unification parser as
PC-KIMMO's word grammar component. Thus the file format of a PC-PATR
sentence grammar is identical to a PC-KIMMO word grammar. PC-PATR's
user interface is also very similar to PC-KIMMO. PC-PATR actually has
PC-KIMMO's morphological parsing engine built into it. This means that
you can use a morphological description such as Englex to provide
lexical entries "on the fly" as you parse a sentence. The new entries
provided by the morphological parser can then be saved to a word
lexicon file. Here is a sample parse of the sentence "the brave knights
stormed cornwall":

 S
 __________|__________
 NP VP
 _______|________ ____|_____
 Det AJ N VerbalP NP
 | brave knights | |
 DT V N
 the stormed cornwall

 S:
 [ head: [ agr: $1[ 3sg: - ]
 finite:+
 pos: V
 tense: PAST
 vform: ED ]
 subj: [ cat: NP
 head: [ agr: $1
 case: NOM
 number:PL
 pos: N
 proper:-
 verbal:- ] ] ]

Please note that only a _TOY_ grammar of English has been included with
PC-PATR! It is intended only to demonstrate how to write a grammar and
also how to interface PC-PATR with a morphological description (namely
Englex).

PC-PATR is presently designated as an alpha release. This is not
because it is buggy or unstable, but because it still lacks features
that we intend to add.

 PC-PARSE -- a mailing list for SIL parsing software
 ---------------------------------------------------

We are starting a new mailing list to facilitate user support for SIL's
parsing software, presently PC-PATR, PC-KIMMO, and AMPLE (another
morphological parser which eventually will also be embedded in
PC-PATR). The list will be called PC-PARSE. Users of the software are
encouraged to use the list to ask questions, offer tips and solutions
to problems, and exchange data and descriptions. To subscribe to the
list, create a message consisting of this line only in the body:

 SUBSCRIBE PC-PARSE

and send it to this Internet e-mail address:
