Search engine evaluation and Internet user behavior construction

On the challenge, Baidu took two legs to walk the strategy. On the one hand, we have designed and developed a HC system to dismantle complex assessment tasks and distribute them to a large number of non-professional evaluations. On the other hand, based on the valuable user log, we designed a set of experimental framework to carry out ultra-large scale contrast experiments without affecting the online service of Baidu, to obtain the real feedback from netizens and to judge the merits and demerits of the new algorithm. The evaluation algorithm ultimately evaluates the user experience. In practice, we have gained a lot of valuable and interesting experience and would like to share with all the engineers who want to know more about the users.
