FINAL CALL FOR PAPERS
Workshop

Beyond Named Entity Recognition Semantic Labelling for NLP Tasks

URL: http://ai-nlp.info.uniroma2.it/ws_lrec04/

Centro Cultural de Belem
LISBON, Portugal
25th May 2004

In Association with
4th INTERNATIONAL CONFERENCE ON LANGUAGE RESOURCES AND EVALUATION
LREC2004
Main conference 26-27-28 May 2004

Motivation and Aims

Although it is generally assumed that improvements in language
processing will be made through the integration of linguistic
information and statistical techniques, the reality is that language
is very diverse and looking for specific patterns of words that repeat
enough to be statistically significant tends not to be a very fruitful
task: sequences longer than three words are not generally repeated
often enough to be statistically significant. At the same time, the
identification of named entities: Names, dates, places, organizations
etc., has proved to be a very useful preliminary task in many natural
language processing systems are interested in pursuing approaches
which extend this notion by identifying and labeling other semantic
information in a text, in such as way as to allow repeatable semantic
patterns to emerge. Our interest is in attacking the data sparseness
problem by exploring ways to collapse (semantically) related phrases
which are expressed by different word sequences.

As this seems closely related to previously proposed class-based
language models (see for example Brown et al. 90 in Computational
Linguistics), it is distinguished because the empirical notion of
classes used in the previous work (e.g. classes made up of
collocationally similar words) are replaced by semantically justified
sets.

Notice how Name Entity (NE) tagging and Word Sense Disambiguation
(WSD) represent, in terms of granularity and representational
complexity, two extremes of a single general problem: semantic
disambiguation. Semantic disambiguation serves thus the purpose of
improving the generalization power of statistical models. One of the
questions here is how to determine a suitable level of clustering (for
NE identification and for WSD) that would lead to high accuracy and to
performance improvement by obtained statistical models.

Reason of Interest

It is to be noticed that a set of independent research work focused
recently on the statistical treatment of semantic phenomena
(e.g. WordNet navigation as a stochastic process, as studied in Light
and Abney or in Ciaramita & Johnson) highly correlates with the
research program proposed above.

The workshop will represent a forum where experience from lexical
semantics and statistical learning will be presented and fruitful
discussion among researchers in both fields will be promoted. The
workshop is expected to attract researchers and practitioners from a
range of areas as well as developers of large scale semantic resources
who are interested in effective methods of semantic labeling.

Topics (to be addressed in the workshop include, but are not limited
to)

* Methods for lexical - semantic annotation of corpora
* Methods and Standards for lexical semantic representation of
dictionary information
* Lexico-semantic taxonomies
* Existing sources of classification: dictionaries, thesauri and
computerized ontologies
* Corpus-driven methods for semantic disambiguation
* Feature selection for semantic disambiguation
* Lexico-semantic tagging of very large corpora
* Algorithms and methods for disambiguation of semantic phenomena
* Statistical learning models and their applications to semantic
labeling
* Computational learning frameworks for Natural Language Learning
* Semi-supervised and unsupervised statistical semantic disambiguation
* Evaluation of semantic disambiguation

Workshop format

The workshop will be a half-day event with position statements from
invited speakers (half an hour each) with two hours for 4-6
presentations of scientific papers. Submissions are intended to
present works in progress and more completed works which fall within
the scope defined by the topics listed above. A final 1 hour open
discussion among all the workshop participants will be moderated by
the organizers. In order to stimulate an interesting general
discussion each member of the program committee will be invited to
submit a position statement of max. 1000 words.

Submission

Participants are invited to submit an extended abstract of max. 3500
words concerning one or more of the topics of interest. Each accepted
paper receives a slot of 25 minutes for presentation (15 minutes talk
and 10 minutes for discussion). Each submission should show: title;
author(s); affiliation(s); and contact author's e-mail address, postal
address, telephone and fax numbers. Submissions must be sent
electronically in PDF to the following address:

issue.
