中文简介: | 这项工作使用单个文档和少量分类文档来探索用户当前活动的建模。我们描述了WeMAC方法,该方法用于组合来自不同来源的证据,从而为用户的活动提供了依据。我们使用两种不同的文档类型报告对WeMAC模型的评估:电子邮件和网页;在小型文档集和大型文档集上评估其性能;并对照“单包”方法评估其性能。我们报告了令人鼓舞的结果,平均F1值为0.5 0.7。 |
课程简介: | This work explores the modelling of a user’s current activity using a single document and a very small collection of classified documents. We describe the WeMAC approach for combining evidence from heterogeneous sources to give a prdict the user’s activity. We report evaluation of the WeMAC model using two different document types: emails and web pages; assess its performance on both tiny document sets and larger sets; and assess its performance against a “one bag” approach. We report promising results, with average F1 value of 0.5-0.7. |
