Method for node ranking in a linked database
Inventor: Lawrence Page
Assignee: The Board of Trustees of the Leland Stanford Junior University
US Patent 7,058,628
Granted June 6, 2006
Filed July 2, 2001

Abstract

A method assigns importance ranks to nodes in a linked database, such as any database of documents containing citations, the world wide web or any other hypermedia database. The rank assigned to a document is calculated from the ranks of documents citing it. In addition, the rank of a document is calculated from a constant representing the probability that a browser through the database will randomly jump to the document. The method is particularly useful in enhancing the performance of search engine results for hypermedia databases, such as the world wide web, whose documents have a large variation in quality.

FIELD OF THE INVENTION

This invention relates generally to techniques for analyzing linked databases. More particularly, it relates to methods for assigning ranks to nodes in a linked database, such as any database of documents containing citations, the world wide web or any other hypermedia database.

A durat 5 ani.

E defapt o completare a celui din 2001. O adaugare defapt.
PageRank avea trademark si pana acum.

Poate apucati sa cititi inainte de a face afirmatii.

Aici e vorba chiar de documentatia din 2001. Dureaza 5 ani sa iei patentul. Daca era o completare actuala a celui din 2001 nu era filled 2001 ci 2005 sau 2006.

Anyway, irelevant ce e si cand a fost depus. Totusi mie mi se pare ca este acelasi lucru pe care l-au spus in lucrarea de doctorat, numai ca aici spun mult mai scurt.

**Krumel** · 10th June 2006, 10:56

Da, e chiar documentatia din 2001. Dar s-a mai adaugat o sectiune. Deci nu e tot aia. Sau e tot aia cu o sectiune adugata.
Te rog, citeste si fa comparatii.

New Google Patent Hints at Direction of Social Search

The USPTO published yesterday a patent awarded to Google that provides clues to Google's plans for social search, including details about how Google will use human editors to help facilitate algorithmic search.

The patent, system and method for supporting editorial opinion in the ranking of search results, describes processes whereby Google can better judge user search intent based upon whether the query matches a "theme" of queries on Google's servers.

Those "themes" include topics commonly occurring in search queries from users in Google's network. According to the patent, editors will develop these query themes by looking at search query logs and developing categories of information.

The editors develop query themes by surveying user search logs, experimenting with test search queries, and examining search results lists.

The patent also includes details about distinguishing between "favored" and "non-favored" sources. Such sources would be determined by a variety of factors, including host name.
