Re: Distance & word context.

Hi Justin,

You might be interested in the following paper:

Grefenstette, G. (1996) "Evaluation Techniques for Automatic Semantic Extraction: Comparing
Syntactic and Window Based Approaches", in Boguraev and Pustejovsky (eds) Corpus Processing for
Lexical Acquisition, The MIT Press, 205-216.

It's not "new" any more, but it seems to correspond to the opposition between distance and roles within
grammatical constructs you are alluding to.

I hope it helps,

Thierry

Re: Distance & word context.

I don't have a reference, but I think I remember Ken Church (?) mentioning 'long-range collocations, up to
c. 10k words apart' in c. 1992?

Related to this, I am also interested in any work that courts the

I know of this paper:

	Address = {Saarbr{\"u}cken, Germany},
	Author = {Kenneth W. Church},
	Booktitle = {Proceedings of the 18th conference on Computational

	Title = {Empirial Estimates of Adaptation: The chance of Two Noriegas  
is closer to $p/2$ than $p^2$},
	Year = {2000}}

We've been exploiting the distance between repeated syntactic  
constructions (not terms) in our work on structural (syntactic)  
priming.  For a more applied paper, see

Sentence diagramming software

Does anyone know of free or on-line automatic sentence-diagramming 
software?  I'm looking for software that would parse text, identify parts 
of speech, and create the kind of *graphical* diagrams that children learn 
to make in grammar school.  I'm looking for something that goes beyond 
drawing software that you can use to diagram manually, and again stress 
the graphical part.

FYI, there's a pretty nice, on-line, non-graphical diagrammer at 
http://1aiway.com/nlp4net/services/enparser/Default.aspx .

Thanks,

 				Seth

There are many different notions of 'distance'.  One example
is the term "semantic distance", for which Google provides
26,700 hits.

Some such connections can be defined by context-free rules:

    Letter  ->  Salutation  Body  ComplimentaryClose

The two terms "salutation" and "complimentary close" give
16,400 hits on Google.

Re: Distance & word context.

Hello,

Thank you to everybody who has contributed to my search. So far it's  
helped me un-earth a small pile of extra relevant material (including  
some I had accidentally buried :-)).

Kudos!

Fwd: Re: Distance & word context.

John,

Thank you very much for your feedback.

I was referring to what one might call the linear "physical distance"  
or "narrative distance" in corpora (as would correlate with the time  
between terms occurring as a reader reads, if you like). Hence my  
citing "distance-weighted context windows" as an example of one way in  
which this is considered (also referred to as "ramped" windows etc).  
As there doesn't seem to be a consistent established terminology - at  
least none that I'm familiar with - Google is unsatisfactory by  
itself. I'm definitely not asking about semantic distance.

What I ceratinly didn't make clear is that I'm particularly interested  
in approaches that have been used to *mine* these relationships from  
corpora, as well as general linguistic discussions concerning their  
existence, rather than formal ways in which they can be expressed (as  
per context-free grammar) - although I am certainly interested in the  
models that have made such mining possible.

Do you have any more insights which I might find useful in light of  
this? Perhaps something that you might expect to have fewer hits  
(owing to our now hopefully increased precision)?

Many thanks!

For a related case of analyzing email messages into components,

(a) the EMU work on text-to-speech (e.g., Richard Sproat, Jianying Hu, Hao
Chen, "EMU: An E-mail Preprocessor for Text-to-Speech," IEEE Signal

(b)  my work for presenting and summarizing email-based discussion lists
(Newman, P. S. Exploring discussion lists: steps and directions.
Proceedings of the Second Joint ACM/IEEE-CS Conference on Digital Libraries

are relevant.  The approaches used are similar, employing manually weighted
finite-state machines to find the best decompositions.
