Systems and methods for direct navigation to and/or highlighting a specific portion of a target document such as query-relevant portion of the document are disclosed. The method may include generating a search result link to a search result document and generating an instruction to a client document browser to navigate directly to an intra-document portion related to the query within the search result document. The search result may include a snippet extracted from the search result document such that the instruction causes navigation directly to at least a portion of the snippet. The instruction may be an artificial anchor undefined in the search result document, e.g., designated by a preassigned artificial anchor designator. The client browser may have an artificial anchor module installed to execute the instruction to navigate directly to and optionally highlight the intra-document portion within the target document in response to the document link being selected.

According to one aspect, a computerized method and apparatus for generating and presenting search snippets that enable user-directed navigation of the underlying audio/video content. The method involves obtaining metadata associated with discrete media content that satisfies a search query. The metadata identifies a number of content segments and corresponding timing information derived from the underlying media content using one or more automated media processing techniques. Using the timing information identified in the metadata, a search result or “snippet” can be generated that enables a user to arbitrarily select and commence playback of the underlying media content at any of the individual content segments.

Embodiments are described for a system and method for redirecting Internet traffic away from illegitimate web sites. A redirect process includes a typo identifier engine and a direct navigation engine. The typo identifier engine generates a list of domain names based on common typographical variations of legitimate brand domains, and common direct navigation domains. A web crawler process verifies if the generated domain name are registered. The sites are classified as either legitimate or illegitimate based on a series of defined rules and analysis of parameters, such as site content, registrar identity, and owner. The direct navigation engine compares the user's request with the list of known illegitimate domains found by the typo identifier engine. If a match is found, the system replaces the user requested domain name with a redirected domain name.

A hierarchy improvement system and associated method automatically locate “weak spots” in a hierarchical organization of a Web site, where the visitors' expected locations of Web pages, Web sites, or Web points (i.e., nodes) do not coincide with their actual locations. The system mines the users' access patterns, such as backtracks, and determines the most likely locations of the Web pages by discovering or inferring backtracks. Once the expected locations are defined, the system either forwards the expected locations with a high frequency of repetition or a substantially high benefit value to the Web site administrator for corrective action, such as adding direct navigation links from the expected locations to the target pages, or automatically adding such navigation links.

With a client connected to a server, an agent tool simulates user interaction and traversal of dynamic web pages, causing the server-side processes to serve HTML pages to the client. As these pages are served, they are collected by the agent, modified to include static hyperlinks to replace the server side directed navigation logic, and then persistently stored in local files where they are available for off-line navigation by a browser without the need for accessing the server(s). In effect, the HTML pages are published.

A navigation receiver mounted on a moving vehicle receives navigation signals transmitted from global navigation satellites. The navigation signals are separated into direct navigation signals, navigation signals reflected from an object, and navigation signals reflected from an environmental surface. The signal separation is based on algorithms including various combinations of signal strength, change in signal strength, delay time, spectral width, change in spectral width, and user-defined thresholds. The navigation signals reflected from an environmental surface are eliminated from further processing. The position of the navigation receiver is calculated based on the direct navigation signals. The object is detected, and the position of the object is calculated, based on the navigation signals reflected from the object. If the object is determined to lie in the path of the moving vehicle, a command can be generated to avoid collision between the moving vehicle and the object.

Techniques provide for the dynamic display of a page-oriented information asset using an audio output mode. Pluralities of elements in the page-oriented information asset are determined based on chapters, sections, paragraphs, sentences, words and the like. The elements are rendered to an audio output mode. Optionally selectable representations of the elements are also determined and output using a 3-dimension-like rendering to a visual output mode. The 3-dimension-like rendering of the visual representations of the elements shows how the current element relates to the other elements and its location within the page-oriented information asset. The 3-dimension-like rendering provides visual orientation or context within the page-oriented information asset. The visual representations of the elements are optionally selectable as spatial context indicators providing direct navigation control to support reading, browsing and information retrieval tasks within the page-oriented information asset. Speech input is also optionally recognized as a direct navigation control.
