Abstract
Systems and methods for scheduling document crawling are provided in which a list of document identifiers is obtained. Each respective document identifier identifies a corresponding document on a network. For each respective document identifier in the list of document identifiers, a content change frequency of the corresponding document is determined and a first score for the document identifier that is a function of the determined content change frequency of the corresponding document is also determined. The first score is compared against a threshold value. The document is scheduled for crawling based on the result of the comparison. The content change frequency for a respective document identifier is determined by comparing information stored for successive downloads of the document corresponding to the document identifier.
