OpenKG Chain: A Blockchain Infrastructure for Open Knowledge Graphs

Abstract The early concept of knowledge graph originates from the idea Semantic Web, which aims at using structured graphs to model world and record relationships that exist between things. Currently publishing bases as open data on Web has gained significant attention. In China, CIPS(Chinese Information Processing Society) launched OpenKG in 2015 foster development Chinese Open Knowledge Graphs. Unlike existing knowledge-based programs, chain is envisioned a blockchain-based infrastructure. This article introduces first attempt implementation sharing chain, trust network. We have completed test underlying blockchain platform, well on-chain OpenKG's dataset toolset fine-grained crowdsourcing triple level. also proposed novel definitions: K-Point Token, can be considered measurement value user value. 1033 contributors been involved two months testing blockchain, cumulative number recordings triggered by real consumers reached 550,000 with an average daily peak more than 10,000. For time, tested realized entity/triple granularity At present, all operations datasets OpenKG.CN, triplets OpenBase, are recorded corresponding will generated assigned trusted mode. Via this effort, looks provide credible traceable knowledge-sharing platform for community.
