International Classification:

G06F 1300

US Classification:

709224, 709217

Abstract:

A method and apparatus are provided for indexing electronic documents that include one or more visible text portions and one or more non-visible text portions. The method includes the step of identifying an electronic document. Once the electronic document is identified, a set of words is selected from a particular tag type that is associated with one or more non-visible text portions of the electronic document. Each word in the selected set of words is compared with words in the one or more visible text portions of the electronic document. An index word set is then determined for the electronic document based on matches between words in the selected set of words and words in the one or more visible text portions of the electronic document.

US Classification:

707 7, 707 3, 707 10, 709203, 709219

Abstract:

A method and apparatus for using network traffic logs for search enhancement is disclosed. According to one embodiment, network usage is tracked by generating log files. These log files among other things indicate the frequency web pages are referenced and modified. These log files or information from these log files can then be used to improve document ranking, improve web crawling, determine tiers in a multi-tiered index, determine where to insert a document in a multi-tiered index, determine link weights, and update a search engine index.

International Classification:

US Classification:

707 3, 707 5, 715254

Abstract:

Techniques are provided for generating descriptions of matching resources in a manner that takes into account the kind, quality, and relevance of the available sources of information about the matching resources. For example, after the search engine identifies matching resources based on the query terms, the search engine determines the kinds of available sources of information about each matching resource. For each matching resource, based on the kinds of available sources of information about the matching resource, one of a plurality of processes is selected to generate a description for the matching resource. Using the content-sensitive description generation techniques described herein, a single result set may include abstracts that were generated using several different processes, where the difference in process corresponds to a difference in the kind, quality, and relevance of the available sources of information about each matching resource.

Abstract:

Techniques are provided for generating search results that include, instead of or in addition to the traditional abstract links, other links to content that the user of a search engine may consider helpful. These other links are referred to herein as “non-traditional abstract links”. In general, the search engine generates non-traditional abstract links that attempt to anticipate the “next move” by the search engine user. By selecting a non-traditional abstract link from the abstract of a matching resource, the user is able to navigate from the search result listing directly to locations other than the top of a matching resource.
