Meeting Description:

The LDC-IL, is organising a series of events to bring together researchers
working in these areas, to share their knowledge with other researchers. 

Call for Papers

The following changes have been made regarding the conference:
Last date of abstract submission: 10 January, 2010
Abstract acceptance notification: 15 January, 2010
Submission of full length paper: 28 February, 2010

Each of the events in the series will focus on one aspect of computational
grammar at a time and thereby address issues related to these themes.
Parts-of-speech (POS) tagging is the basic building block of any NLP work,
hence, the first step in developing the computational grammar for any language.

The POS tagging is not about just providing a tag to a token but it encompasses
a whole range of grammatical information for that token in the sentence from a
particular language. Besides, designing the tagset for a specific NLP purpose,
preparing annotation guidelines and interannotator agreement are also very
important. It is an active research area in NLP.

POS tagging is useful in speech generation, speech recognition, parsing, machine
translation, information retrieval, information extraction, WSD (word sense
disambiguation), question-answering etc. Moreover, it is an intermediate step
for higher NLP tasks such as parsing, semantic analysis and machine translation.
Especially regarding Indian languages, POS tagging adds many more dimensions,
involving many complex issues that arise out of script, writing convention
specific to the language, inherent POS ambiguities as well as with respect to
unknown tokens and variations in the text.

POS tagging can be both manual as well as automatic. Manual tagging, though more
accurate, is a time-consuming, long and continuous process. Hence, the automatic
tagger is essential to speed up the process of POS tagging with less chance of
errors and inconsistencies. Various automatic POS taggers have been developed
worldwide using linguistic rules, stochastic models and hybrid taggers (a
combination of both). Different kinds of taggers have certain advantages as well
as disadvantages. Automatic tagging is a challenge for Indian languages which
are highly inflectional and morphologically rich. Hence, the development of high
accuracy POS taggers is a challenging task.

The event endeavours to concentrate on the challenges in the area of POS tagging
and to share and investigate novel advancements in the area specific to a
language as well as cross-linguistically. It also aims to provide researchers an
academic space to discuss the most recent information about theories, tools and
techniques explored for POS tagging, and focuses on linguistic as well as
computational issues related to it. The event intends to endorse the area of POS
tagging as a consolidated research area and aims towards widening its horizon.

Abstracts of no more than 500 words (including references) mentioning the title
of the paper, author(s) name, institutional affiliation, and email address
should be submitted by the due date in *.rtf or *.pdf format to the following
email address: rsrishti at gmail.com or ldc-richa at ciil.stpmy.soft.net
