Preface
Research in Natural Language Processing (NLP) has taken a noticeable leap in the recent years.
Tremendous growth of information on the web and its easy access has stimulated large interest in
thefield. India,withmultiplelanguagesandcontinuousgrowthofIndianlanguagecontentontheweb,
makes a fertile ground for NLP research. Moreover, industry is keenly interested in obtaining NLP
technologyformassuse. Theinternetsearchcompaniesareincreasinglyawareofthelargemarketfor

andotherlanguages. Thereisalsoaneedforsearchingcontentinmultiplelanguages,andmakingthe
retrieved documents available in the language of the user. As a result, a strong need is being felt for

technology are getting interested in natural language technology, and those interested in pursuing

NLP products. Each consortium project is a multi-institutional endeavour working with a common
softwareframework,commonlanguagestandards,andcommontechnologyenginesforallthedifferent
languages covered in the consortium. As a result, it has already led to development of basic tools for
multiple languages which are inter-operable for the tasks of machine translation, cross lingual search,
handwritingrecognitionandOCR.
Inthisbackdropofincreasedstudentinterest,greaterfundingandmostimportantly,commonstandards
and interoperable tools, there has been a spurt in research in NLP on Indian languages, whose effects
we have just begun to see. A great number of submissions reflecting good research is a heartening
matter.
