Workshop on Corpus-Based Natural Language Processing
17 – 31 December 2001
Organised by
AU-KBC Research Centre, Anna University, Chennai
Jointly with
Language Technology Research Centre, IIT, Hyderabad
National Centre for Software Technology, Mumbai
RCILTS-Tamil, Anna University, Chennai
Tamil University, Thanjavur
The workshop focussed on introducing the participants to the emerging
techniques in machine processing of natural languages, which are based on language
corpora. It emphasized mainly on Statistical Processing and Machine Translation. The
main Workshop was preceded by a three-day Preparatory Workshop meant for
participants not having the required background.
Faculty of the Workshop
Eminent persons both from India and abroad, who are working in this field for a
long time now, conducted the workshop. Their role included giving lectures, acting as
guides for the projects that were taken up during the workshop and motivating the
participants to take up further research in NLP. The list of faculty members includes:
Prof. Aravind K Joshi
University of Pennsylvania
U.S.A
Dr. B. Srinivas
AT&T Research Labs
New Jersey.
Dr. Anoop Sarkar
University of Pennsylvania

Lecture Topics
Various lectures covering the broad spectrum of Corpus-based Natural Language
processing were delivered during the workshop that includes,
1.Finite State Machines
2.Finite State Transducers
3.Chunking
4.Tagging
5.Statistical Parsing
6.Language Models
7.Hidden Markov Model
8.Tree Adjoining Grammar Formalism
9.Paninian Grammar Formalism
10.Information Retrieval
11.Classifiers
12.Clustering
13.Latent Semantic Indexing
14.Word Sense Disambiguation
15.Machine Translation models
16.Statistical Machine Translation
The workshop was organized in a way that, lectures were given during the
morning sessions and in the afternoon sessions, participants were working in the projects
assigned to them. The lectures topics were picked in such a way so as to cover the
techniques used in Statistical Natural Language Processing and as well as to make the
participant to understand the underlying concepts to enable him to take up individual
research work in his area of interest.

Executing Group Projects by participants constituted an integral part of the
workshop. The idea is to enable the participants to continue the work on their projects
even after they go back to their institutions. There were 11 groups with each group
working on one project and the faculty members of the Workshop guided these projects.
The following were the Projects taken up during the workshop:
1.Morphological Analyzer for Tamil
2.Rule based Parser
Tamil
Telugu
3.Statistical Parser for Hindi
4.Document Classifier
5.Document retrieval
6.Word Sense Disambiguation: Mapping of English senses to Indian languages
7.Named Entity Recognizer
8.Terminology Extraction from Medical Literature
9.Example Based Machine Translation
English - Hindi
English - Tamil
10.Super Tags for Indian Languages
Hindi
Tamil
11.Cross-linking of bilingual dictionaries
Hindi - Telugu
Hindi - Tamil
Hindi - Kannada
Hindi - Marathi
