SYSTEMS AND METHODS OF UNIVERSAL RESOURCE LOCATOR NORMALIZATION

摘要

Disclosed herein are method, systems and architectures for normalizing identifiers corresponding to resources using normalization rules that can be generalized for use with different resources. By way of a non-limiting example, an identifier can be a uniform resource locator (URL), and a normalization rule can be used to normalize URLs that correspond to different resources, e.g., content. A normalization rule can be generated by generalizing two or more normalization rules corresponding to different resources, such that a content determinative component is generalized. A normalization rule can be defined to include a context portion used to determine the rule's applicability to an identifier, and a transformation portion that identifies the transformations to be applied to an applicable identifier to yield a normalized form of the URL. A generalization of two or more normalization rules can include a normalization of one or both of the context and transformation portions.
