Could a search engine effectively rely on searchers to help clean up Web spam in search results? asks Bill Slawski, pointing to a patent filed by Microsoft. The patent describes a way a search engine could identify Web spam by combining information from searchers about pages with information gathered from an automated system for identifying web spam.
Slawski looks at how Google, Microsoft and Yahoo allow searchers to identify pages each might consider Web spam. He also tells us how the engines might use crowdsourcing and the signals Microsoft might use to identify spam in search results.
