Embodiment Construction
[0047] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0048] The two-class mail classification algorithm based on active learning and negative selection proposed by the present invention includes the following steps:
[0049] S1. Utilize a mail set consisting of legitimate mail and spam S 0 Establish the user’s positive interest set P and negative interest set N, and The specific process is as follows:
[0050] S11, eliminate S 0j (S 0j ∈S 0 , 1≤j≤|S 0 |, |S 0 | Means S 0 The number of elements in the set) in the attachments, tags, punctuation marks, special symbols, and stop words, the remaining text is segmented and the root is restored to form S ...
