METHODOLOGY OF COMPARING TECHNOLOGIES BETWEEN COMPETITIVE COMPANIES USING STATISTICAL METHOD AND MACHINE LEARNING METHOD

摘要

The present invention relates to a method for analyzing technologies between competing companies. The method comprises the following steps of: generating word-based data from patent documents to be analyzed; extracting core keywords from the word-based data using the keyword analysis; generating an international patent classification (IPC) code network through the IPC code analysis from the word-based data; and generating technology analysis data by using the extracted core keywords and the generated IPC code network. As the technology analysis data includes information on technologies that are common to competing companies and technologies that are specific to individual companies, technologies between competing companies can be compared and analyzed through the extraction of core keywords for a patent document and the establishment of an IPC code network.
