Abstract: To build a common user model platform which can share data and provide more comprehensive and accurate user information to all sites accessed to the platform, the platform provided data interfaces and algorithm interfaces to interact with the third-party sites, focused on how to solve the conflict of user data from different data sources in order to form a unified user model, finally achieved sharing of algorithms, models and data. The experimental results show that it is more accurate and comprehensive to build user model on this platform.

摘要： 为了构建一个公共的共享数据的用户模型平台，给各个接入该平台的网站提供更全面、更准确的用户信息，平台提供了数据接口和算法接口用于与第三方网站的交互，重点研究了如何解决来自不同数据源的用户数据的冲突，从而形成统一的用户模型的问题，最终实现了算法和模型以及数据的共享。实验结果表明，该平台更能准确、全面地构建用户模型。
