Adopting the basic concept and fundamental method of fuzzy mathematics, the author provide a method for establishing the main rating data of drilling RIGS.
本文采用模糊数学的概念和方法,提出了确定石油鉆机主参数系列的方法。
For each subset, user rating data is grouped by user. First line for a user is formatted as.
对于每个子集,用户数据根据不同用户分组。
This paper proposes a collaborative filtering recommendation algorithm based on trust mechanism. Direct trust is based on common rating data and indirect trust is based on the predict data.
