[comp.ai] Recent Natural Language Interfaces

yvonne@gufalet.let.rug.nl (Yvonne Vogelenzang) (07/10/90)

I'm writing a paper about natural language interfaces and I wonder if anyone 
can tell me more about such interfaces. I'm especially interested in projects
after say 1985, since all the literature I can find describes programs that 
were written before then. So if anyone knows anything about systems that were 
developed recently, I'd very much like to know this. Please send all the info 
you have to my email-adress. 

Thanks!!!!!

The posting that follows is a reply to a recent posting by
Yvonne Vogelenzang asking about recent natural language interfaces.
I tried to reply via email, but my message bounced.
Since the content is of moderately general interest
I'll try to followup instead -
no reference to the Chinese Room is made, though.

What do you mean by natural language interfaces? 
I'll assume that you are asking about systems
which are able to understand natural language questions
(and possibly reply in english too).

You can find lots of information about recent natural
language interfaces in the journal Computational Linguistics,
as well as in the proceedings of the ACL;
 your Computer Science Dept. should have both.
Especially useful would be to get the proceedings of the
1988 conference on Applied Natural Language Processing,
where lots of systems where discussed.

The most famous `recent' systems include:

- TEAM, developed at SRI at the beginning of the '80s;
  its `final' description appeared in Artificial Intelligence Journal,
  1987
- UC, still under development at Berkeley, by the group of
  Wilensky; a description appeared in Computational Linguistics
  in 1989 or 1988;
- The system developed by Kathleen Dahlgren and Michael McCord
  of IBM: again, a description appeared in Computational
  Linguistics in 1988 or 1989, plus Kathy had a book in 1987
  called `Naive Semantics' which is a great book;
- XTRA, under development at University of Saarbruecken;
  a description appeared in the International Journal of Man Machine Studies;
- LILOG, under development at the University of Stuttgart
  and IBM Germany.
- LUCY, under development at MCC by the group of Elaine Rich;

Len Schubert, has developed a story understanding system called ECOLOGIC 
which makes use of GPSG to build
a Montague-like representation called Episodic Logic; a description of
Episodic Logic will appear in Artificial Intelligence Journal shortly.
The group of James Allen at Rochester is developing a discourse understanding system,
but the work is still in its beginnings; again, I could tell you 
more since I am involved in this.

Last but not least, one system I have worked on, WISBER, developed by the University of Hamburg, 
Siemens Munich et al. We had tons of technical reports 
(available by writing at the
 Department of Computer Science), plus papers at ECAI, COLING and GWAI.
If you are in a hurry, start looking at the first systems I've mentioned,
in that order.


Hope this helps

Thanks very much to everyone out there who reacted to my request for 
NLI info. Although there was something wrong with my mailbox, I received
most of the messages, some of which were very useful to me.

I received some requests from people to summarize the reactions I received,
so here it comes:

One project I know of (I worked there myself) is the CFID project, AKA ESPRIT
P527 "Communication Failure In Dialogue". A number of papers have appeared on 
this project; one of them is in this year's AIMSA conference (the authors are 
Ferrari,Prodanof, Reilly and Saffiotti), another was in COLING'86 (Ferrari, 
Reilly). Saffiotti and I wrote a paper (it appears on the Proc. of the 1988 
IEEE Conf. on AI Applications) on a knowledge representation language we 
designed that was tailored to the needs of such an interface.

I received a long article from the university of Saarbru"cken, Dept. of
computer science, D-6600 Saarbru"cken 11, West-Germany, about XTRA, their 
Natural Language Access System for Expert Systems. This article contained a 
lot of references, far too much to put on the net.
Here's one:

I hope I have helped some of you with this summary.
