Ito and Tanaka (2019) “Token-Curated Registry with Citation Graph”

Abstract: In this study, we aim to incorporate the expertise of anonymous curators into a token-curated registry (TCR), a decentralized recommender system for collecting a list of high-quality content. This registry is important, because previous studies on TCRs have not specifically focused on technical content, such as academic papers and patents, whose effective curation requires expertise in relevant fields. To measure expertise, curation in our model focuses on both the content and its citation relationships, for which curator assignment uses the Personalized PageRank (PPR) algorithm while reward computation uses a multi-task peer-prediction mechanism. Our proposed CitedTCR bridges the literature on network-based and token-based recommender systems and contributes to the autonomous development of an evolving citation graph for high-quality content. Moreover, we experimentally confirm the incentive for registration and curation in CitedTCR using the simplification of a one-to-one correspondence between users and content (nodes).

Ito and O’Dair (2019) “A Critical Examination of the Application of Blockchain Technology to Intellectual Property Management”

Abstract: This chapter critically investigates the application of blockchain technology for intellectual property management. To date, there have been relatively few critical discussions of the feasibility of utilising blockchain technology for this purpose, although much has been written, in media and industry sources, about the potential. Our aim, by contrast, is to examine possible limitations—and, subsequently, to suggest tentative solutions to the limitations we identify. Specifically, this chapter aims to examine the use of blockchain technology for intellectual property management from two perspectives: operation and implementation. We conclude that, while commentators often focus on technical characteristics of blockchain technology itself, it is the incentive design—which was fundamental to the original Bitcoin proposal—that is also critical to truly decentralised, and disintermediated, intellectual property management.
