Domain classification using domain co-occurrence information

摘要

Domain classification based on domain co-occurrence information derived from client request behavior is provided. The network requests of clients are analyzed to determine domain and time information. Distance information is generated based on the time between requests for a plurality of domains. The distance information for individual clients is combined to generate distance information for domain pairs. The distance information represents an amount of time or other measurement between queries associated with the two domains of the pair. By examining the client requests, a measure of the distance or relatedness of two domains may be determined. Co-occurrence information for a first set of domains is generated based on the co-occurrence of domains in the first set with domains in a second set of domains. Based on the co-occurrence information, a domain classification can be generated for domains in the first set of domains.
