Microsoft patent on website and site content reliability scores for Bing Search ranking

Microsoft has released a patent named Web Content Reliability Classification that talks about how to develop a reliability score for a website or content on a website. The present technology identifies reliable content by leveraging expert scoring for a small amount of web content by iteratively extending these scores to other content based on how web content is linked. In one aspect, an output of the technology is a high reliability score and a low reliability score for a web content. The high reliability score represents conformance to high reliability sites, while the low reliability score represents conformance to low reliability sites. The low reliability score is similar, but uses outgoing links to low reliability sites instead of incoming links from high reliability sites.
