在个性化推荐系统中，协同过滤技术是应用最成功的技术。协同过滤技术包含几种典型代表，基于用户的协同过滤、基于内容项的协同过滤、基于关联规则的协同过滤等，这些方法都有各自的优缺点和应用领域。通过对传统协同过滤算法进行分析，根据移动用户餐饮个性化的特点，引入杰卡德系数，将杰卡德系数引入到协同过滤中并对算法进行改进，最终在移动用户餐饮个性化推荐中取得了较为理想的效果。
在箇性化推薦繫統中，協同過濾技術是應用最成功的技術。協同過濾技術包含幾種典型代錶，基于用戶的協同過濾、基于內容項的協同過濾、基于關聯規則的協同過濾等，這些方法都有各自的優缺點和應用領域。通過對傳統協同過濾算法進行分析，根據移動用戶餐飲箇性化的特點，引入傑卡德繫數，將傑卡德繫數引入到協同過濾中併對算法進行改進，最終在移動用戶餐飲箇性化推薦中取得瞭較為理想的效果。

In the personalized recommendation system,collaborative filtering technology is one of the most successful tech?nologies in application,which contains a few typical modes:collaborative filtering technologies based on the users,content items,association rules and so on,. These technologies have their own advantages,disadvantages and application fields. By the analysis of the traditional collaborative filtering algorithm,Jaccard coefficient is introduced according to the catering persona?lized characteristic of the mobile users. Jaccard coefficient is introduced into collaborative filtering to improve the filtering algo?rithm.,An ideal effect was obtained in catering personalized recommendation for mobile users.
