Title  Intelligence ACM/ICPC Training Platform

Abstract Intelligence system and user experience has been hot and hot on the internet. Intelligence system involves much areas which contains data mining, machine learning and open platform. User experience is more and more import because the product’s experience is the most straight express to the users who’s not  care much about the technic detail. It is worth to discuss on how to transform technic to a good user experience. This paper express an intelligence ACM/ICPC training platform integrated an access control system, an problem search system, an problem recommendation system. With technical as RBAC, crawler, label-manage, database indexing and searching and data mining, the system has improved its intelligence and conveniences. Thus, we have redesigned the user interface to make an improvement on the usability of the system, which intend to create a better user experience.

Keywords  Intelligence System, User Experience, Search, Data Digest, Role Based Access Control, Crawler
