Title: Using Multi-Objective Optimization for Word Sense Induction and Disambiguation
Authors: Prabhakaran, S.
Keywords: Computer Science & Engineering
Issue Date: 2015
Abstract: Word Sense Induction is a task of automatically finding new senses to words. Hierarchi- cal Dirichlet Process, a topic modelling concept performs this clustering Task by inducing different senses to clusters. An existing implementation of Simulated Annealing Based Multi-objective Optimization Algorithm(AMOSA) performs Search Results Clustering and it initializes itself with random clusters as its starting solutions. It searches better solutions through Simulated Annealing mechanism. In Simulated Annealing after each iteration, new solutions obtained through mutation are compared with solutions at current iteration using multiple con icting Objective functions, compactness and separability. The motivation is to improve the results by initializing AMOSA with output of a Topic Modelling Based solution to Word Sense Induction problem, by guiding the clustering Task. Due to the availability of page ranks for documents to be clustered, two new Objective Functions Page Rank based Compactness and Page Rank based Separability are introduced to work along with the other Objective Functions of AMOSA.
