This paper proposes a keyword extraction process, based on the PageRank algorithm, to reduce noise of input data for measuring semantic similarity. This paper will introduce several features related to implementation and discuss their effects. It will also discuss experimental results which showed significantly improved document retrieval performance with this extraction process in place.
