Six degrees of cohesion in patent citation network
Itakura, Kelly & Geva, Shlomo (2011) Six degrees of cohesion in patent citation network. In Cunningham, Sally Jo, Scholer, Falk, & Thomas, Paul (Eds.) Proceedings of the Sixteenth Australasian Document Computing Symposium 2011, Royal Melbourne Institute of Technology, Australian National University, Canberra, ACT, pp. 79-87.
While the phrase “six degrees of separation” is widely used to characterize a variety of humanderived networks, in this study we show that in patent citation network, related patents are connected with an average distance of 6, whereas an average distance for a random pair of nodes in the graph is approximately 15. We use this information to improve the recall level in prior-art retrieval in the setting of blind relevance feedback without any textual knowledge.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
