sentences will contain answers in the most direct form, whereas other sentences will contain more indirect answers. For example, given the question “Where is Glasgow?”, one possible direct answer is “Glasgow is in Scotland.” More typically the answer appears in context in a sentence such ...
本篇主要介绍基于标签的推荐算法,涉及了3个原理较简单的计算方法(Simple Tag-based、Normal Tag-based、Tag-based-Tfidf ),以及python代码实现。 1.概述 1.1 如何定义用户画像 用户画像即是对用户行为特征的总结归纳和描述,以更好的提升业务质量。 用户画像的关键步骤: ...
