		 COMPARING CORPORA

			 October 2000

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.

Message 2: ACL'2000-Recent Advances in NLP and IR Workshop

Date: Thu, 6 Jul 2000 12:23:40 EDT
From: Priscilla Rasmussen <rasmussecs.rutgers.edu>
Subject: ACL'2000-Recent Advances in NLP and IR Workshop


- ------------------------------------------------------------------
 SECOND CALL FOR PAPERS
 ACL'2000 Workshop on Recent Advances in Natural Language Processing
 and Information Retrieval
 October 7/8, 2000
 Hong Kong University of Science and Technology
- ------------------------------------------------------------------


Aims and scope
- ------------

This workshop aims at fostering the interaction between researchers in
the areas of Natural Language Processing (NLP) and Information
Retrieval (IR), and furthermore, promoting discussions on the current
and potential benefits of common approaches to related research
challenges. The central topic is the application of Language
Technologies to Information Retrieval, including (but not limited to): 

* the role of lexical-syntactic information in mono- and multilingual
IR, including morphology, phrase detection and treatment, word sense
disambiguation adapted to IR needs, acquisition and use of lexical
resources, etc.

* empirical evidence regarding the use of NL techniques in different
retrieval scenarios, typification of such scenarios, and the
discussion of evaluation measures beyond precision/recall variants.

* interaction between NLP and IR techniques in topics related
to both areas such as Cross-Language and Interactive Text Retrieval,
Question Answering, Information Extraction, Text Summarization, Text
Data Mining, etc.

The growing research and application possibilities provided by the
increased amount of networked information have motivated new attempts
to explore the relationship between NLP and IR. For researchers in
IR, a compelling challenge is to move from (monolingual) document
retrieval within controlled text collections, to actually retrieving
information, rather than individual documents, from multilingual,
heterogeneous and dynamic webs of interlinked documents and online
services. The reciprocal challenge for NLP research is to scale up,
adapt and possibly reshape techniques and resources to help bridge the 
gap between document and information retrieval in practical
applications. Papers describing pragmatic, empirically tested
approaches facing these issues are especially welcome.
