		          COMPARING CORPORA

			     October 2000

	    Hong Kong University of Science and Technology


THEME
=====

Anyone who has worked with corpora will be all too aware of
differences between them.  Depending on the differences, it may, or
may not, be reasonable to expect results based on one corpus to also
be valid for another.  It may, or may not, be appropriate for a
grammar, or parser, based on one to perform well on another.  It may,
or may not, be straightforward to port an application from a domain of
the first text type to a domain of the second.  Currently,
characterisations of corpora are mostly textual and at different
levels of generality.  A corpus is described as ``Wall Street
Journal'' or ``transcripts of business meetings'' or ``foreign
learners' essays (intermediate grade)''.  It would be desirable to be
able to place a new corpus in relation to existing ones, and to be
able to quantify similarities and differences.

Allied to corpus-similarity is corpus-homogeneity. An understanding of
homogeneity is a prerequisite to a measure of the similarity -- it makes
little sense to compare a corpus sampled across many genres, like the
Brown, with a corpus of weather forecasts, without first accounting
for the one being broad, the other narrow.

Given the centrality of corpora to contemporary language engineering,
it is remarkable how little research there has been to date on the
question.  Biber's work, coming from sociolinguistics, has made a
considerable impact, with various researchers in computational
lingustics taking forward the model (Biber 1989, 1995).  Studies in
text classification, genre and sublanguage are also salient, but it is
rarely evident how well the technologies ddeveloped in these fields are
suited to measuring corpus similarity or homogeneity.

The workshop will welcome contributions concerned with measuring and
comparing corpora using quantitative methods, from any field.
