Research Abstract |
Technical words and effective words acquisition from the patent document is useful, for example, it can be applied to automatic generation of patent map. Therefore, we first propose an automatic generation method of patentmaps from patent documents by extraction of expressions using cross-bootstrapping. Then we propose a method to a combination of grammar patterns and bootstrap method using the clue word,to obtain these words. We develop a method to analyze in detail the object to be extracted for automatic patent map generation.
