Abstract: Social reading platform has been deeply embedded in the infrastructure of human knowledge production and service.In the era of social reading,human knowledge production and service have crossed the threshold of "viewpoint" and entered the period of "public knowledge".More and more members of the public use the social reading platform to carry out knowledge dissemination and consumption activities,so the knowledge service function of the social reading platform has become increasingly prominent.Different from the knowledge service in the traditional media era,the knowledge service in the social reading platform presents its own characteristics in terms of mechanism,technical logic and path.In terms of service mechanism,cooperation,interaction,weak connection and multi-chain production and servicedocking are the mainstream mechanisms for social reading platforms to provide knowledge services;in technical logic,the knowledge services of social reading platforms follow three logics of connection-interaction,co-creation and sharing and platform control.In the path,the social reading platform should make a breakthrough in content push,user experience,circle marketing and the integration and innovation of entertainment and knowledge services.In the future development,the knowledge service on the social reading platform should take the road of "knowledge +",change the "drilling" service into the "extraction" service,and build a more systematic knowledge service platform.

Key words: social reading platform, knowledge service, mechanism, technical logic, path
