A rewrite component automatically generates rewrite rules that describe how uniform resource locators (URLs) can be rewritten to reduce or eliminate different URLs that redundantly refer to the same or substantially the same content. The rewrite rules can be applied to URLs received when crawling a network to increase the efficiency of the crawl and the corresponding document index generated from the crawl.

Automatic generation of rewrite rules for URLs

Systems and methods for triggering actions are set forth. According to one embodiment, a method comprising determining at least one triggering condition associated with an article, correlating the triggering condition with information associated with a user, and providing the user with a notification relating to the triggering condition is described.

Methods and systems for triggering actions

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 &#x201c;anchor-heavy&#x201d;. 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).
