摘要
The present invention relates to a method of analyzing a technology using a patent document, comprising the steps of extracting words from documents to be analyzed, generating a document-word matrix using the extracted words, Generating a document-keyword matrix by selecting a keyword from a word matrix, generating a regression model using the document-keyword matrix, calculating a significance probability (p (n)) of the parameters of the generated regression model, selecting a keyword corresponding to a parameter having a value of -value, and deriving a relation between the keywords by using the significance probability between the selected keywords, thereby deriving a technology layer using statistical analysis, By using the hierarchy, objective and accurate patent analysis is possible.
