US Patent:

7305610, Dec 4, 2007

Filed:

Aug 14, 2000

Appl. No.:

09/638082

Inventors:

Jeffrey A. Dean - Menlo Park CA, US
Craig Silverstein - Stanford CA, US
Benedict Gomes - Berkeley CA, US
Sanjay Ghemawat - Mountain View CA, US

Assignee:

Google, Inc. - Mountain View CA

International Classification:

G06F 15/00
G06F 17/00

US Classification:

7155011, 715513

Abstract:

Techniques for crawling hyperlinked documents are provided. Hyperlinked documents to be crawled are grouped by host and the host to be crawled next is selected according to a stall time of the host. The stall time can indicate the earliest time that the host should be crawled and the stall times can be a predetermined amount of time, vary by host and be adjusted according to actual retrieval times from the host.

International Classification:

G06F 17/21

US Classification:

715206, 715207, 715208

Abstract:

A system modifies documents to aid users in determining which of the entries in the documents to choose. The system identifies a document that includes one or more entries. The system determines a score for each of the entries and modifies the identified document, or entries in the identified document, based on the determined scores. The system then provides the modified document to a user.

Appl. No.:

9/013668

Inventors:

Craig D. Silverstein - Stanford CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G06F 1730

US Classification:

707 1

Abstract:

A method and apparatus for almost-constant-time re-clustering of corpus subsets with customizable time/precision tradeoff, is usable in a basic browsing method, such as Scatter/Gather, to successfully partition a large document collection into clusters of related documents. The user is first presented with a clustering of the entire corpus into metadocuments from which the worst metadocument is selected and replaced with its "children". Children containing no documents of interest are pruned and the remaining metadocuments are further expanded until a predetermined number of children metadocuments are obtain. The resulting metadocuments are then reclustered. The process is repeated until the user obtains the desired degree of specificity.
