Analysis of chemical substance name appearing in patent publication

Abstract

The chemical substance names described in the patent publications have various descriptions and the description of the name depends on the author. Such variation causes hindering information sharing. Auto-extraction of chemical substance names is useful for information sharing. In order to grasp the current situation, we examined and analyzed the occurrence frequency of chemical substance names and description method in patent publication (chemical field). Chemical substances were tagged by type, such as single substance, mixture, polymer, etc., and the frequency of chemical substance names by type in each document was compared. As an attempt to extract chemical substance names, we used morphological analysis for detecting the names, and used the unique characters of the names for selection the names.
