Abstract:

Detecting so-called “navigation bars” (or “nav bars”) in a (Web) document by determining whether or not nodes of a parse tree of the (Web) document are “anchor-heavy”. Generally, a navigation bar can be thought of as text, such as a hyper-text link or anchor text for example, without any immediate content. Once a navigation bar is detected, objectionable navigation bars (i. e. , navigation bars, the rendering of which would be objectionable to users without special re-authoring), can be distinguished from non-objectionable navigation bars (i. e. , navigation bars which would not be objectionable to users with no special re-authoring). Objectionable navigation bars may be distinguished from non-objectionable navigation bars by: (a) determining whether the navigation bar is so small that normal rendering would not be objectionable; (b) determining whether the navigation bar presumably conveys meaningful content; and/or (c) determining whether the navigation bar is a component of a non-objectionable navigation bar (where all components of the non-objectionable navigation bar are navigation bars themselves).

US Classification:

709226

Abstract:

A method of distributing files operates in a system having a master and a plurality of slaves, interconnected by a communications network. Each slave determines a current file length for each of a plurality of files and sends slave status information to the master, the slave status information including the current file length for each file. The master schedules copy operations based on the slave status information. The master stores bandwidth capability information indicating data transmission bandwidth capabilities for the resources required to transmit data between the slaves, and also stores bandwidth usage information indicating a total allocated bandwidth for each resource. For each schedule copy operation, an amount of data transmission bandwidth is allocated and the stored bandwidth usage information is updated accordingly. The master only schedules copy operations that do not cause the total allocated bandwidth of any resource to exceed the bandwidth capability of that resource.

US Classification:

707203, 707 1, 707 2, 707 5, 707100

Abstract:

Duplicate documents are detected in a web crawler system. Upon receiving a newly crawled document, a set of documents, if any, sharing the same content as the newly crawled document is identified. Information identifying the newly crawled document and the selected set of documents is merged into information identifying a new set of documents. Duplicate documents are included and excluded from the new set of documents based on a query independent metric for each such document. A single representative document for the new set of documents is identified in accordance with a set of predefined conditions.
