Abstract: A system, apparatus, and method are disclosed for providing a single source for searchable content by mobile devices. Mobile user agents crawl host sites to determine whether there is content that may be viewed by any of the mobile user agents. If files are identified as viewable for a given mobile user agent, the site is tagged as crawlable. A best mobile user agent may also be identified for that site, based on number of files viewable, response time, file mobileness, or the like. The sites may be discovered by instrumentation of URLs with mobile device keywords, performing a backlink analysis to discover interlinking of mobile device related sites, exploring URLs of a known host name for potential starting points for mobile device sites, or employing a list of known popular conventional sites with a mobile user agent for possible redirections to a potential mobile device web site.

Abstract: A system, apparatus, and method are disclosed to identify and tag documents that are mobile documents in that they are compatible with limited capability devices, such as mobile phones. A website hosting a document is checked to determine whether the website considers the document to be a mobile document. The document is also for indications that the document is a mobile document. The indications include a content type, a document type, and/or markup tags that are consistent with a mobile document. A URL for the document is also checked for parameters indicating a mobile document. The above information is used to determine one or more categories of mobile devices that could display or otherwise process the document. A confidence level is determined indicating a degree of confidence that the document is a mobile document. The information is used for searching documents for those that are likely to be mobile documents.
