A method for decomposing textual contents of a web page using Search Tree technology, wherein binary search trees accelerate analysis of text to thereby determine if a word matches words and phrases which are associated with one or more categories of content, wherein scores are given to words using the first or the second method according to the degree of correlation to categories, and wherein a total score for any category exceeding a user selectable threshold assigns a web page to one or more categories, and wherein categories that are exceeded will cause an Internet filter to take an appropriate action, such as blocking access to or providing a warning when accessing a web page.
