A method for web content filtering, between web transmission contacting nodes, executing the following steps to determine bypassing web information: ( 1 A) building web page filtering decision criteria, at least including keyword category, a relevance probability chart for every keyword, a blocking threshold, and a bypassing threshold, and a score deviation (SD) having scores for each category; ( 1 B) getting web page from a web server; ( 1 C) looking for a next keyword; ( 1 D) determining whether a current word is a keyword, if yes, further proceed to the next step; if not, going to step ( 1 H) and continue to check an information document; ( 1 E) computing a score deviation between a highest score and a second higher score from each category based on the relevance probability chart; ( 1 F) determining whether the score deviation exceeds the blocking threshold, if yes, label the web page as a forbidden one; if not, proceed to the next step; ( 1 G) determining whether the score deviation is lower than the bypassing threshold, if yes, label the web page as a bypassing one; if not, proceed to the next step; and ( 1 H) reading next word from the web page and determining whether an end has been reached, if yes, label the web page as a bypassing one; if not, return to step ( 1 D).
