Hi Jon (and everyone),

I hope you will find this useful.

>how to access those archives as much as I would!

Notes on The PCP Web Page
(from our paper at the Barcelona Congress)

The address of the PCP site here is:

It has:-

* A brief introduction to PCP (largely Kelly quotes)

* A link from the intro to an HTML version of the paper on Kelly's
Psychological Geometry that was written for "New Psychologist". This
attempted to place Kelly historically in the growth of cognitive science
and show how his geometry is equivalent to the intensional logics used in
knowledge representation. It has a good set of refs for a newcomer.

* A note on David Nightingale's PCP list server with details of how to
join, and hypertext links to the mail archives. We have hypertext indexed
the PCP mail archives and linked these to the home page. They are grouped
by quarter and indexed by thread, date, subject and author.

* A link to other PCP-related web sites. It requests url's for other sites.

* A link to PCP ftp and gopher sites. This currently has links to archives
of Gaines/Shaw and Boose/Bradshaw papers. It again requests url's for other

* A note on NAPCN and how to join.

* A note on EPCA and how to join.

* A note on the Barcelona meeting.

* Contents of JCP as posted by Bob Neimeyer.

* Links to information on how to set up and run a web site.

* Links to web sites at Stanford, Hanover and Carleton which keep track of
psychology-related material and sites.

* The psychology resource sites have also entered links to the PCP page so
that it is readily accessible to anyone searching for related material.

* We asked several groups maintaining indices of psychological activities
on the Web to put in links to the PCP page here so that other psychologists
world-wide could find it.

* We also put in links to the index pages at other sites so that someone
coming into the PCP page could find other psychological material.

* There is also a link to WebGrid, a repertory grid elicitation, modeling
and comparison service operating on the web. This is an implementation of
RepGrid operating as an HTTP server on the web. You go through a normal
elicitation based on triads, breaking matches, and so on, and get the
FOCUS, PrinCom and Socio analyses back as graphics.

All the grid data is stored in the web documents, so that you can save them
on your own computer, use the data locally, and continue the elicitation
and processing by reloading the locally stored file. You can annotate
elements with HTML text so that comments, images and sounds can be used in
the elicitation. These can be stored on your local machine or anywhere on
the Internet.

We have been running WebGrid for courses here this semester on a rather
slow old Mac that no-one wanted, but we have now moved it to a sparkling
new Power Mac that should be capable of supporting general use.

Setting Up Web Sites

For those setting up web sites for the first time, Brian Gaines wrote a
long 'how to' paper on supporting scientific communities on the Internet
for a multimedia conference. It has all the details on formats,
conversions, tools, what not to do, etc. It is on the KSI ftp site in Word
RTF and PostScript formats:


This paper also addresses the issue of putting up interactive programs in
the client-server environment of the web. It is simply done. However, the
current interface available through HTML level 2 forms is very restrictive.

We are designing the systems such that they can be used by other programs
as services, as well as by end users. This is an exciting aspect of the
open client-server environment that the web offers. It supports world-wide
collaborative research. For example, one group can put up an analysis
program, e.g. a principal component agent, and another group can put up an
elicitation system that uses that agent for analysis. There is tremendous
scope for loosely-coupled community research.

Accessing the Web

We've had a number of requests for info on how to access World-Wide Web.
It's not as simple as email because you need a higher-quality connection to
the Internet that gives you reasonable speed TCP/IP access. If you are
coming in over a modem, this means a 14,400 baud modem through a PPP or
SLIP connection. The speed is important because the web supports images and
these tend to be larger data structures than text.

The browser to use currently is Netscape from Netscape Corporation. It is
available for Macs, PCs and Unix systems, and is used by over 80% of WWW
users. It is free for educational and personal use, and $39 for other use.
The ftp site are:


Electronic Journals and Publication On The Internet

There is increasing publication on the Internet, and a growing number of
electronic journals. Universal access is still a problem, and the best
solution currently seems to be dual publication with the electronic version
free and the paper version low in cost. JAIR, the Journal of Artificial
Intelligence Research from Morgan Kauffman is a good example with strong
refereeing, rapid publication, free Internet access and a paper version at
$39 a year.

However, increasingly also authors are just bypassing the current systems
and putting their work up for access through ftp and WWW. It is fast and
simple, reaches a large population, and allows multi-media materials,
simulations, access to raw data, and so on, to be incorporated.

The nice thing about WWW is that is very open and egalitarian. We don't
intend this to be THE PCP page but rather one of many, all cross-linked.
Any PCP group can put up material on the Internet which reflects its own
approach and applications.

So, the next step is for everyone to send us the url's of any material they
have up so that this page can be linked to others.

In the short term, those who do not yet have web sites can send us a note
of any organizations or meetings that should be added to this page. We can
also add papers in electronic format to the archive (we have already done
this for the Boose/Bradshaw material sent to us by John Boose).

The simplest way to send electronic material is to ftp it to
and mail one of us that it is there and should be put into the archives)

In the long term, it is best if as many groups as possible maintain their
own WWW/ftp/gopher sites. The Internet is a nice arena in which to publish
what you like with no heavy hand of publishing bureaucracies!
