Abstract
A connectivity server for a collecting, arranging and representing data defining the interconnection of pages on the World Wide Web (Web). A URL Database stores URLs and associates a fingerprint and CS_id with each URL. The URL Database interface is operable to translate between any two of a URL, a fingerprint, and a Host_id. A Host Database associates a Host_id with each distinct hostname in the URL Database. The Host Database interface is operable to accept a Host_id and return a number equal to the number of URLs on the respective host and to return the CS_ids of those URLs. A Link Database stores links between source URLs and destination URLs. The Link Database interface is operable to retrieve, for a given CS_id, the number of inlinks to and outlinks from the URL corresponding to the CS_id. In an embodiment characterized by a single processor, with access to all databases stored in RAM links and URL information may be retrieved sufficiently rapidly so that applications that touch every link, even multiple times, may execute in real time, in a few minutes or hours. Representative applications enabled by the connectivity server include static ranking of pages (eigenranks), query precomputation, mirror-site detection, and related-page identification.
