Spam flood detection methodologies

摘要

A computer-implemented method analyzes a website to determine whether the website represents a potential source of spam, and, in response to the analyzing, flags content of the website as spam content. The determination can be made by computing a total number of content items associated with the website, calculating a publication frequency of the content items, and determining whether the website in its entirety represents spam content based on the total number and the publication frequency. The determination could also be made by generating a signature of a webpage containing a content item, obtaining an occurrence count for the generated characterizing signature, and, when the obtained occurrence count is greater than a threshold count, identifying the content item as spam.

1. A computer-implemented method comprising:
analyzing characteristics of a website to determine whether the website represents a potential source of spam content, wherein the analyzing comprises:
computing a total number of posts associated with the website;calculating a publication frequency for the total number of posts in posts per minute based on a ratio of the computed total number of content items to a difference between a publication time of a newest content item in the website and a publication time of an oldest content item in the website; anddetermining whether the website in its entirety represents spam content, based on the computed total number and the calculated publication frequency, wherein the determining comprises: comparing the calculated publication frequency to a threshold frequency; and when the calculated publication frequency is greater than the threshold frequency, identifying the website in its entirety as spam content; and in response to the analyzing, flagging the website in its entirety as spam content.
