Keyword selection and processing strategy for applying text mining to patent analysis

摘要

Previous studies have applied various methodologies to analyze patent data for technology management, given the advances in data analysis techniques available. In particular, efforts have recently been made to use text-mining (i.e. extracting keywords from patent documents) for patent analysis purposes. The results of these studies may be affected by the keywords selected from the relevant documents but, despite its importance, the existing literature has seldom explored strategies for selecting and processing keywords from patent documents.
