A text-mining-based patent network: Analytical tool for high-technology trend

TL;DR: A network-based analysis is proposed, an alternative method for citation analysis that provides richer information and thus enables deeper analysis since it takes more diverse keywords into account and produces more meaningful indexes.
Journal ArticleDOI

An approach to discovering new technology opportunities: Keyword-based patent map approach

TL;DR: Text mining is used to transform patent documents into structured data to identify keyword vectors and principal component analysis is employed to reduce the numbers of keyword vectors to make suitable for use on a two-dimensional map.
Journal ArticleDOI

Large engineering project risk management using a Bayesian belief network

TL;DR: This paper presents a scheme for large engineering project risk management using a Bayesian belief network and applies it to the Korean shipbuilding industry, and identifies differences of project performance risks between large-scale and medium-sized shipbuilding companies.
Journal ArticleDOI

A systematic approach for identifying technology opportunities: Keyword-based morphology analysis

TL;DR: A keyword-based MA is proposed that is supported by a systematic procedure and quantitative data for concluding the morphology of technology and technical and managerial strategy for in-house R&D or cross-licensing can be supported by examining the morphology portfolio of technologies.
Journal ArticleDOI

Customization of technology roadmaps according to roadmapping purposes: Overall process and detailed modules

TL;DR: The main purpose of this research is to provide guidance for customizing roadmaps and adopt a modularization method for mass customization and suggest a set of different roadmaps for different purposes such as forecasting, planning, and administration.
