Report Errors
Patents contain detailed information about the developed technology. Therefore, patent analysis is used to establish R&D strategies and identify technology trends. For this analysis, patents must be assigned to several predefined technical categories. Patents are given unique codes corresponding to technical categories, which have been manually classified by some experts. Technology classification performed by hand has the disadvantage that errors can occur and cost and time are high. Attempts are being made to classify technologies by applying quantitative methods such as text mining, which have recently been developed, to patents. Quantitative patent classification is cost-effective and reproducible. In this paper, we propose a method of converting patent text, which is non-image data, into image data and classifying technology through clustering. The proposed method performs image data transformation on vectorized information with one-hot encoding and distributed representation techniques in text mining, and performs technology classification by forming clusters. As a result of collecting and experimenting with actual patent data, it was confirmed that the technology classification performance was improved when TFIDF and W2V were converted to images.
