Abstract: A method for classifying a document using identified patterns includes determining frequent patterns based on a group of resources, where the frequent patterns include sets of words associated with resources that are related to a particular topic; determining frequent anti-patterns based on another group of resources, where the frequent anti-patterns include sets of words associated with resources that are not related to the particular topic, where the second group of resources is different from the first group of resources; determining a probability that the document is related to the particular topic based on the frequent patterns and the frequent anti-patterns; and determining a topic classification of the document based on the determined probability.

Abstract: Classifying a document using identified patterns includes determining frequent patterns related to a topical classification based on identification of a first group of resources; determining frequent anti-patterns that are related to a non-topical classification based on identification of a second group of resources; an classifying the document based on the frequent patterns and the frequent anti-patterns.

Abstract: Systems and methods for classification of documents based on topic to which the documents pertain are described herein. In one implementation, the method comprises computing a probability of a document being topical based on a number of constituent elements that are topical and a total number of constituent elements and computing a probability of the document being anti-topical based on a number of constituent elements that are anti-topical and the total number of constituent elements. The method further comprises determining whether the probability of the document being topical is greater than the probability of the document being anti-topical. Thereafter, the method includes classifying the document as topical on determining the probability of the document being topical to be greater than the probability of the document being anti-topical.
