INTRODUCTION
 NE Wordnet Project for Assamese & Bodo started in 2009.
 NE Wordnet Project for Assamese & Bodo have been developed with expansion approach with the Original Hindi Wordnet structure against the IDs and Concept of Hindi Wordnet.

NE Wordnet Development Project outcomes till now
Validation
 All the Assamese and Bodo Wordnet activities have been reviewed by the Professors of the Department of
Assamese, Modern Indian Language & Bodo of Gauhati
University as well as other invited resource persons.

 The developed NE Wordnet structured in the form of Database, integrated with interactive Interface is ready for different NLP research and Development. Different NLP application and research related works already started using the NE WordNet.
 Automatic Bilingual Dictionary Construction: Assamese-Bodo
Dictionary Construction : Prototype developed at Gauhati University.
 Web based Automatic Multilingual Dictionary Construction:
Assamese-Bodo-Nepali-Hindi-English Dictionary Construction: Full
Web based System ready: By Gauhati University Team.
 Intelligent Document Categorizing System: Prototype Developed and
Tested at Gauhati University: Research Paper already accepted for
GWA-2010.

Problems Faced During Development for Assamese

In common synsets of Assamese and Bodo, a few number of synsets do not have proper Assamese word to represent. So they are not entered yet. Those left synsets have been send to the expert committee to review.

The main challenge in expansion approach is in one to one mapping.

Problems Faced During Development for Bodo
 Challenges in Expansion
Bodo is a developing language. It does not have a very strong linguistic resource. Also literature resource is very limited. The language does not have enough vocabulary, and new and new words are being discovered, coined and added. As a result, the development of Bodo Wordnet faces typical and frequent problems, and overcoming the problems to accommodate expansion of the
Hindi Wordnet with one to one mapping has been a big challenge

Workshop/conference organized and participated by the member groups:

 Integration and collaboration of the man powers in the field of
Linguistics and Computing; Trained man power development in the field of NLP, Local Language Technology Development.
 Through this project a new breed of researchers in language technologies have been trained for proper skills and knowledge sets. As in these local languages the linguistic and Literature studies in formal education are with minimum computational linkage, and with no training/exposure for interlinking of linguistics and computing, the project facilitates in developing a team of interdisciplinary researchers. The project has contributed in expertise development and awareness creation in latest in machine translation, lexical semantics, cross lingual IR etc. in specific.
