Message 1: NEW MAILING LIST: Hybrid Models: Learning and Architectures

Date: Thu, 05 Oct 1995 09:13:20 NEW MAILING LIST: Hybrid Models: Learning and Architectures
From: Ron Sun <rsuncs.ua.edu>
Subject: NEW MAILING LIST: Hybrid Models: Learning and Architectures


ANNOUNCING A NEW MAILING LIST:

The <Hybrid Models: Learning and Architectures> mailing lists.
 -------------------------------------------

As we discussed at the CSI workshop at IJCAI in this August,
we now establish this new mailing list for the specific purpose of
exchanging information and ideas regarding hybrid models, especially models
integrating symbolic and connectionist processes. Other hybrid models,
such as fuzzy logic+neural networks and GA+NN, are also covered.

This is an unmoderated list. Conference and workshop announcements,
papers and technical reports, informed discussions of specific
topics in hybrid model areas, and other pertinent messages
are appropriate items for submission.
Email your submission to hybrid-listcs.ua.edu, which will be automatically
forwarded to all the recipients of the list.

Information regarding subscription is attached below.
For questions and suggestions regarding this list, send email to
rsuncs.ua.edu (only if you have to).

This mailing list has incorporated the old HYBRID list at Brown U. maintained
by Michael Perrone (thanks to Michael), and included names of those who
attended the 1995 CSI workshop or expressed interest in it.
(To remove your name from the list, see the instruction at the end of this
message.)

Regards,
- Ron Sun


 =======================================================
The University of Alabama Department of Computer Science has set up a list
service for this:

Subject: Re: Summary, part II of Tense/Aspect particles


 Two weeks ago, I posted a message asking for examples of tense or aspect
 being expressed by morphologically unbound particles. I received a large
 number of responses and found more valuable data than I could have hoped.
 I would like to thank the following linguists in addition to those
 mentioned in my first thank you list posted last week:

 Nicholas Ostler
 Richard C. DeArmond
 Steve Matthews
 Beatrice Santorini
 Loran A. Billings
 Susan Meredith Burt
 Ricky Jacobs
 Dorothy Disterheft
 Alistair Knott
 Paula S. Newman
 Annabel Cormack
 Mike Dickey
 Geoffrey Millar
 Jill Hart
 Mike Mackenzie
 Charles Randriamasimana
 Andi Wu


 Thanks you very much for your help!

Message 3: Soundex

Date: Thu, 05 Oct 1995 18:11:58 Soundex
From: <MLEWELLENguvax.acc.georgetown.edu>
Subject: Soundex

On Oct. 4, the following question, under the subject "SOUNDEX Software
Question" was posted:

>Dear Linguists!
>
>There is a wonderful search algorithm for English words based on phonetic
>properties of the searched items. It is called SOUNDEX. Essentially, it
>provides a way to conduct fuzzy searches and find everything which
>sounds somewhat like the entered words with a given degree of proximity.
>
>Does anybody know of similar algorithms for foreign languages? Has anybody
>done any customization of the original SOUNDEX written 25 years ago? Please
>reply directly or through the group.

Questions about Soundex occur every once in a while on the linguist list.
The Soundex algorithm actually has fairly little to do with phonetic
properties, even though it is often called a "phonetic" technique. It
has been used primarily in name-matching applications. The following
discussion has been lifted from a rough draft of my Ph.D. thesis on
using artificial neural networks to match romanized Chinese names:

	In compression (or "phonetic") techniques, letters will be
assigned to certain groups and be expressed by a symbol for that group;
additionally there are rules for truncating names and combining vowel or
consonant clusters. The most well-known of the compression algorithms
is the Soundex technique, which was originally developed for the 1890
census. Its original form is as follows:
	The code (or "key") consists of four alphanumeric symbols, derived
in the following manner:
 rrtain the first letter of the name, and drop all occurrences
 oo A, E, H, I, O, U, W and Y, in other positions;
 tte last three symbols are the digits 1-6, chosen from the
 ffllowing table:
				11B, F, P, V
				2	C, G, J, K, Q, S, X, Z
				33D, T
				44L
				55M, N
 66 R
 ii consecutive letters of the original name have the same
 ccde, delete all but the first letter;
 ii a code has less than three digits, fill out the key with
 zzros; if a code has more than three digits, delete the
 eecess digits. (Knuth 1973:391-392)
 TTe technique seems to have been concerned largely with Eurocentric
names, but even with these kinds of names, the technique has substantial
problems with both precision (the ratio of relevant names retrieved to
all names retrieved, a measure of how many undesirable matches are
returned) and recall (the ratio of relevant names retrieved to all
relevant names, a measure of how many desirable matches are found).
Nevertheless, the system worked well enough to continue to be used
today, and to spawn many variant schemes and competing algorithms
(Hermansen 1985:16-23, Taft 1970:48-92)*. A practical advantage of
compression techniques is that much of the computational work can be
done before an actual name search by compressing all names beforehand,
thus speeding up name searches, as only a new name entered need be
analyzed, before comparing it against all of the already-compressed
names in the database.

* Hermansen (1985) dissusses in more detail the strength and
weaknesses of Soundex and its variant and competitor algorithms,
while Taft (1970) presents a comparison of 23 compression algorithms.

 ONLINE PROFESSIONAL DEVELOPMENT SEMINAR!

in whole language approaches to the teaching of reading and writing

This message supplements our previous message on this subject, with two
new pieces of information: additional telephone and fax numbers of the
publisher of the assigned text for the seminar; and an exciting announcement
about the author of the book, Marie Wilson Nelson.
 **************

We are also pleased to announce that the author of the assigned text,
_At the Point of Need_, Professor Marie Wilson Nelson, has graciously agreed
to participate in the seminar and to answer questions on her book.

 ***************

This online seminar is being offered free of charge on the TESLFF-L branch
of the TESL-L (Teachers of English as a Second Language) electronic forum.
train teachers in the use and adaptation of the Fluency First (Whole
Language) approach to teaching ESL/EFL reading and writing, based on the
research and writing of linguists such as John Mayher and Stephen Krashen.

The online seminar leaders are Adele McGowan-Gilhooly and Anthea Tillyer.
The initial seminar will run from November 1, 1995 to June 1, 1996. For
this first pilot seminar, there will be no credit and no "homework". We
plan to offer graduate credit (CUNY) for later offerings of this seminar.
