What do cats and Internet security have in common? If you had attended Microsoft\u2019s TechFest 2007 on Tuesday in Redmond, Wash., you would know.At the event, which gave Microsoft Research a chance to demonstrate technologies that may one day turn up in Microsoft or third-party products, the research group out of Redmond showed off\u00a0Animal Species Image Recognition for Restricting Access (Asirra), a technology that asks users to identify photos of cats to ensure that humans, not interactive scripts, are accessing certain websites.The problem with human interactive proof (HIP) technologies used today is that they often ask Web users to identify characters, not images, said Jeremy Elson, who works in the Redmond lab of Microsoft Research. HIP technologies are used by websites to ensure someone signing up for a blog or for a service is human, not a software program that wants to spam other users of that service or site. Some of the most common ones display a word that appears slightly distorted.However, "it\u2019s easy for software to recognize characters" and pass for a human, Elson said. But the Microsoft Research team decided that a foolproof way to identify Web users as humans versus software programs was to ask them to identify the difference between dogs and cats from images served up on a site.The group teamed with Petfinder to use its database of photos of dogs and cats as the test images. In return, under each photo, an "adopt me" link can take the user to the Petfinder.com site so they can actually look into adopting the animal they have chosen. Anyone interested in using Asirra can download it from this website and test the software, Elson said.Asirra was one of a host of technologies out of Microsoft Research on display at TechFest Tuesday. It was the first time the event was open to the public, and more than 300 attendees\u2014including press, analysts, bloggers and curiosity seekers\u2014spent the day on Microsoft\u2019s campus in Redmond hearing about and seeing firsthand the work of various research teams.While not every project the 800 researchers spread across five Microsoft Research centers worldwide make it into Microsoft commercial products, researchers and Microsoft product teams are constantly in touch to see how they can work together, said Andrew Herbert, a Microsoft distinguished engineer and director of Microsoft Research in Cambridge, England. "Technology transfer is a contact sport," he said. "You need a lot of contact [with product teams], and you make close contact."Although there are about five reviews of Microsoft Research projects per year by top Microsoft product leaders\u2014including Chairman Bill Gates\u2014sometimes it\u2019s "simply persistence" that gets technology created by Microsoft Research into a product, said Kevin Scofield, general manager of Microsoft Research.One of the technology areas that was of particular focus at Tuesday\u2019s event is from Microsoft\u2019s front lines: search engines. Microsoft Research demonstrated several projects that aim to improve Internet search, and at least one of those technologies\u2014which attempts to make searches more relevant\u2014will likely wind up in Windows Live Search.That technology, called Query Projections, was developed by the Adaptive System and Interaction team at Microsoft Research in Redmond. The technology, as demonstrated by Jurij Leskovec, a Carnegie Mellon computer science student who worked as an intern on the project, creates graphs that map the relationships between links served up when a Web user poses a search query. These graphs are used to see how many of the top search results are actually the most relevant ones for that query, he said.Dan Liegblig, who also worked on Query Projections, said his team talks daily with the Windows Live Search product team and hopes to use its work to improve the relevancy of results delivered by Microsoft\u2019s search engine. However, no time line has been set for when that might happen, he said.Another search technology on display came out of the Integrated Systems Team in Cambridge. That project, called InSite Live, displays a visual graph of a website\u2019s site map and can show, using graphics of pushpins or by highlighting parts of the site, which areas of the site deliver information to search queries. This graph can be used to show website administrators what areas visitors are most interested in, so they might be able to provide better or more information on those pages, said Eduarda Mendes Rodrigues, one of the team\u2019s researchers.While Microsoft may be trying to cook up new search technologies to compete with Google, one area in which the company surpasses the search leader is in its open-door policy that lets outsiders get a glimpse of corporate culture, said one TechFest attendee. Opening up TechFest to people outside the company for the first time is one example of that, said Brad Neuberg, an independent researcher in the San Francisco Bay Area."Something that\u2019s really refreshing about Microsoft is their corporate culture has really opened up," he said. "The joke in the bay area is that if you\u2019re at a party with someone from Google and you ask them, \u2018What are you working on?\u2019 they will say, \u2018I can\u2019t tell you.\u2019 You rarely encounter that with Microsoft and Yahoo."TechFest continues on Wednesday and Thursday, when it is open only to Microsoft employees.-Elizabeth Montalbano, IDG News Service (New York Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
