IWSD Algorithm	Work based on Error Analysis of the IWSD algorithm, divided in various parts, viz. POS based, Ontology based, Ablation test on IWSD parameters. Aim being the importance of contextual part of the scoring function of IWSD algorithm.

“Man vs. Machine Annotation for WSD”

Research Project

CSE Department, IIT Bombay

Guide: Prof. Pushpak Bhattacharyya

Jan 2012 – Mar 2012

Study of Man / Machine

Annotation Process

Our work aimed at understanding the meaning and significance of “contextual evidence”, with respect to the human sense disambiguation task.
The experiments probed into the disambiguation time across different POS categories and ontological categories, they also investigated into the set of clues in the neighbouring words of a pre-defined target word.

“Mechanisms for Sense Discrimination”		Minor Research Project CSE Department, IIT Bombay	Guide: Prof. Pushpak Bhattacharyya Jun 2012 – Aug 2012
Development of “Sense Discrimination Tool”	Emphasized on importance of context and clue words around a target word synset word. Developed “Sense Discrimination Tool” which facilitates the addition of clue words by lexicographers manually into the WordNet database. Laid groundwork for automation of the tool using clues present in the database, using various heuristics.
“Mechanisms for Sense Discrimination”		Major Research Project CSE Department, IIT Bombay	Guide: Prof. Pushpak Bhattacharyya Jan 2013 – Mar 2013
Improvements in “Sense Discrimination Tool” and its Future Implications	Improved the context word searching scenario by providing the lexicographers with a rich corpus. Facilitated the clue addition to database by including Google Hindi Transliteration API within the tool, and by including Concordancer Corpus search. Automated the clue searching by providing with an automatically generated possible clue set. Work on automatic clue addition in future using PMI and G² indexing of the clues. Laid groundwork for a possible future rule based framework to be called, “Discrimination Net”.
