In specific, three types of network analysis, which are centrality analysis, association rule mining analysis and brokerage network analysis, are applied to measure the individual, synergy and group intensity.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>The core safety fields derived from three types of network analysis used by different nature of data algorithms are compared with each other to understand distinctive meaning of cores of patent class such as medical safety, working safety and vehicle safety, differentiating network structure. Also, to be specific, the authors find the detailed technology contained in the core patent class using patent citation network analysis.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Practical implications<\/jats:title>\n<jats:p>The results provide meaningful implications to various stakeholders in organization: safety management, safety engineering and safety policy. The multiple patent network enables safety manager to identify core safety convergence fields and safety engineers to develop new safety technology. Also, in the view of technology convergence, the strategy of safety policy can be expanded to collaboration and open innovation.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title>\n<jats:p>This is the initial study on applying various network analysis algorithms based on patent data (class and citation) for safety management. Through comparison among network analysis techniques, the different results are identified and the collective decision making on finding core of safety technology convergence is supported. The decision maker can obtain the various perspectives of tracing technology convergence.<\/jats:p>\n<\/jats:sec>","DOI":"10.1108\/dta-09-2018-0077","type":"journal-article","created":{"date-parts":[[2019,6,14]],"date-time":"2019-06-14T06:25:15Z","timestamp":1560493515000},"page":"269-285","source":"Crossref","is-referenced-by-count":14,"title":["Multiple patent network analysis for identifying safety technology convergence"],"prefix":"10.1108","volume":"53","author":[{"given":"Jeonghwan","family":"Jeon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5493-5405","authenticated-orcid":false,"given":"Yongyoon","family":"Suh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"140","published-online":{"date-parts":[[2019,6,14]]},"reference":[{"key":"key2021041510005036300_ref001","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1016\/j.aap.2014.04.004","article-title":"Extracting recurrent scenarios from narrative texts using a Bayesian network: application to serious occupational accidents with movement disturbance","volume":"70","year":"2014","journal-title":"Accident Analysis and Prevention"},{"issue":"2","key":"key2021041510005036300_ref002","doi-asserted-by":"crossref","first-page":"144","DOI":"10.1057\/jit.2008.34","article-title":"Visualization of interfirm relations in a converging mobile ecosystem","volume":"24","year":"2009","journal-title":"Journal of Information Technology"},{"key":"key2021041510005036300_ref003","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1016\/j.technovation.2016.04.003","article-title":"Technology fusion: identification and analysis of the drivers of technology convergence using patent data","volume":"55-56","year":"2016","journal-title":"Technovation"},{"key":"key2021041510005036300_ref004","doi-asserted-by":"crossref","first-page":"264","DOI":"10.1016\/j.techfore.2014.03.003","article-title":"Development of data-driven technology roadmap considering dependency: an ARM-based technology roadmapping","volume":"91","year":"2015","journal-title":"Technological Forecasting and Social Change"},{"key":"key2021041510005036300_ref031","unstructured":"Hale, A.R. and Hovden, J.
