Blockchain-based Decentralized Dictionary System for Low-Resourced Languages
Yuwang Zhang, Yohei Murakami (Ritsumeikan Univ) SC2020-37
Abstract (in Japanese) (See Japanese page) 
(in English) The uneven distribution of language resources such as dictionaries and machine translation causes low-resource languages. Especially, bilingual dictionaries between low-resource languages need human contribution to data construction due to less data on the Web. However, the volunteer-based centralized approach such as Wikipedia does not incentivize workers to make dictionary data and imposes a huge amount of operation costs on an operator, which disturbs the sustainable operation. Therefore, we propose the blockchain-based decentralized dictionary system. Specifically, the decentralized dictionary system records the dictionary creation and usage histories on the blockchain which is operated by multiple operators and allocates rewards to contributors according to the ratio of contributions. In this paper, we defined the requirements of the system and implemented a prototype system using Hyperledger Fabric. To validate the system design, we evaluated the throughput and average response time in three typical use cases.
