A Graph-Based Method for Automatic Generation of Multilingual Keyword Clusters and Its Applications

Abstract

We are investigating an approach to automatic generation of Japanese-English bilingual keyword clusters using the keyword lists assigned to academic papers by the authors. The bilingual clusters generated by our graph-based method contain keywords with similar meanings from both languages and could be valuable linguistic resources in various information retrieval (IR) applications. In this paper, we first present an overview of our clustering method and then show several experimental results to evaluate the generated clusters. We also discuss the limitation and possible extensions of the current implementation.
