Abstract

For a researcher in a field with high industrial relevance, retrieving research papers and patents has become an important aspect of assessing the scope of the field. However, retrieving patents using keywords is a laborious task for researchers, because the terms used in patents are often more abstract than those used in research papers, to try to widen the scope of the claims. We propose two methods for translating scholarly terms into patent terms: the "citation-based method" and the "thesaurus-based method". We also propose a method combining these two with the existing "Mase's method". To confirm the effectiveness of our methods, we conducted some examinations, and found that the combined method performed the best.
