摘要
A keyword extraction method is disclosed. The keyword extraction method comprises the steps of: text-mining each of a plurality of technical documents to generate a document-term matrix in which term frequency (TF) of each of a plurality of terms included in each of the technical documents is used as an element; determining a first weight of each element of the document-term matrix using inverse document frequency (IDF); determining, as a second weight, a value that the total sum of the first weights corresponding to the terms is divided by the number of documents that include the terms; and selecting a keyword based on the second weight. Therefore, by text-mining a plurality of technical documents, the technical documents may be analyzed through the structured data.
