[Corpora-List] Distance & word context.

[Costas Gabrielatos]

Perhaps this paper might be of help:

Kim, M-C. & Choi, K-S. (1999). A comparison of collocation-based similarity
measures in query expansion. Information Processing & Management 35(1),
19-30.

Their focus is query expansion, and they consider collocates of candidate
query terms setting the whole text as the span. The interesting twist, as I
see it, is that the span is at the same time well-defined and variable.

Subject: [Corpora-List] Distance & word context.

Hello all,

This list is stimulating as always. I feel it is my turn to throw some
questions around :-)

Can anybody point me towards works (however old or new) that exploit the
distance between terms in a corpus (such as, but not restricted to, the use
of "distance-weighted" context windows). The specific applications are not
important; I am interested in any works that deal with the concept of
distance as opposed to (or in addition to) say frequency counts or
roles/positions within grammatical constructs.

Related to this, I am also interested in any work that courts the notion of
link-distance between words and texts within hypertext structures (such as
the Web); again, specific applications are unimportant.

Finally (for the moment :-)), does anybody know of any (perhaps more
linguistically oriented) works that discuss the existence/importance of
*very* long range dependencies and associations in text (e.g.
Dear... Yours, Results... Conclusion, etc), and the role these play when
considering word context.

Kindest regards to all,
