Abstract: Vacant Technology Forecasting based on Patent Analysis Using an Ensemble Method and Bayesian Clustering
Patent analysis is an important approach to technology forecasting because patents are an important component of developing technology. Also, we use the results of technology forecasting to build the R&D strategies efficiently. In this paper, we consider patent clustering as one of patent analyses. That is, we cluster patent documents in order to forecast the vacant area of a given technology f...
متن کاملVisualization of patent analysis for emerging technology
Many methods have been developed to recognize those progresses of technologies, and one of them is to analyze patent information. And visualization methods are considered to be proper for representing patent information and its analysis results. However, current visualization methods for patent analysis patent maps have some drawbacks. Therefore, we propose an alternative visualization method i...
