New techniques for analyzing search relevance–the way users browse and click through specific content–can improve the algorithms used to rank results, according to two papers submitted by a group of Microsoft researchers
The researchers applied factors such as the amount of time spent “dwelling” on a given page, the page with the most “dwell time” for a user given the user’s average dwell time per page, and dwell time for pages that rank high for sharing search words with their domain. The researchers looked at the fraction of words shared between search terms, and the domain names, page titles or summaries clicked on by the searcher.
“Using the ‘wisdom of crowds’ can give us an accurate interpretation of user interactions, even in the inherently noisy Web search setting. Our techniques allow us to automatically predict relevance preferences for Web search results with accuracy greater than the previously published methods,” the Microsoft research group said in its paper.
