Keyword Clustering for Comparing Documents in Different Languages

J. Tae and D. Shin
Abstract—The objective of this study was to complement natural language processing of a content-based retrieval system by applying keyword clustering. We focused on comparing documents in two languages. To evaluate the performance of this approach, we clustered keywords using the features of documents and performed document clustering using the results of keyword clustering. The purity and the entropy of document clustering revealed that keyword clustering resulted in improvements in the quality of document clustering and allowed us to measure similarities between documents in different languages.

Index Terms—Keyword clustering, dictionary, document clustering, purity, entropy, export control.
