Titre : Technological co-occurrence graphs for innovation analysis Auteurs : Cécile Fauconnet, Revue : Technology and Innovation Numéro : Issue 2 Volume : 6 Date : 2021/03/12 DOI : 10.21494/ISTE.OP.2021.0624 ISSN : 2399-8571 Résumé : Technological co-occurrence graphs in innovation economics are built using patent data, extracting the technological classes associated with inventions by experts from intellectual property offices. Co-occurrence occurs when the same invention is allocated to several technologies. The last decade has seen the development of many original methods for processing patent data via these co-occurrence graphs. The objective of this article is to identify and illustrate the issues of the innovation economy addressed by technological co-occurrence graphs. Éditeur : ISTE OpenScience
