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.
Claims4
A method for ranking documents, the method comprising the computer-implemented steps of:
- identifying links to access a plurality of documents, wherein said links reside in documents other than said plurality of documents, and wherein said links are not presented to a user by a search tool;
- monitoring usage of said links to determine how frequently each of said links are used;
- assigning link weights to at least a subset of said links based at least in part on how frequently each of said links are used;
- and
- determining rankings of documents in said plurality of documents based at least in part on said link weights assigned to said links;
- and
- providing a list of search results that are ranked according to said rankings;
- wherein a first link and a second link link to a particular document of said plurality of documents and the step of assigning said link weights further includes assigning a higher link weight to said first link than to said second link if said first link is used more frequently than said second link to request said particular document.
