Google engineers last week presented an interesting paper at the WWW2008 conference in Beijing which proposes to apply its PageRank system of finding relevant Web pages to radically improve the accuracy of image search results using Google. This new technology is being called VisualRank, according to an fascinating story on the subject in the New York Times. The paper, titled “PageRank for Product Image Search,” (PDF) was published by Yushi Jing and Shumeet Baluja of Google. In it they talk about using PageRank to analyze the “visual link structure” that can be created among a group of similar images. This paper proposes to move away from the current model of many image search engine rankings, described as using “the text clues of the pages in which images are embedded to rank images.”
The new model would “identify ‘authority’ nodes on an inferred visual similarity graph and propose an algorithm to analyze the visual link structure that can be created among a group of images.” A numerical weight would be assigned to each image and, according to the paper, ranking would occur based upon “expected user behavior given the visual similarities of the images to be ranked.” The assumption, this blog points out, is that “people are more likely to go from an image to other similar images.” The Google engineers ran this model through some experiments using 2000 of the most popular products queries. They found “significant improvement, in terms of user satisfaction and relevancy, in comparison to the most recent Google Image Search results.”

Microsoft claims that sales of Windows Vista are chugging steadily onward, and have now passed the 140 million mark. But that wasn’t enough to help Microsoft extend its string of lights-out quarterly financial performances. In its fiscal third quarter earnings call Thursday, Microsoft met the Street’s expectations but saw quarterly profit drop 11 percent from the year-ago quarter. However, the results were skewed by Microsoft’s booking of $1.7 billion in deferred revenue from its Express Upgrade to Windows Vista and Microsoft Office Technology Guarantee programs as well as pre-shipments of Vista and Office 2007.
Qwest Communications International Inc. on Thursday introduced DSL plans with faster download speeds, including one that is the fastest DSL service from a major U.S. phone company. Qwest is charging $104.99 per month for a download speed of 20 megabits per second. For 12 mbps, it is charging $51.99 per month. The prices are $5 lower when combined with local phone service. The plans will be available in 23 of Qwest’s top markets, the company said. By the end of the year, they will be available to 2 million customers. Download speeds on DSL, or Digital Subscriber Lines, from other companies generally top out at 10 or 12 megabits per second.
Oh, shoplifters of the world — you’re not going to unite and take over with these kinds of tactics. A Kirksville, MO. man was arrested on Thursday for trying to boost a $517 Viore (yeah) LCD television by swapping the UPC tag with one from a $3.16 bottle of water.
