05/27(三)邀請俞士綸教授來系演講
各位老師、同學： 系上曾新穆老師邀請 Department of Computer Science at the University of Illinois at Chicago的俞士綸教授至系上演講，檢附詳細資訊及時間地點於文後，機會難得，請大家踴躍參加! 日 期：05月27日(三) 內容摘要： The World Wide Web has become the most important information source for most of us. Unfortunately, there is no guarantee for the correctness of information on the Web. Moreover, different websites often provide conflicting information on a subject, such as different specifications for the same product. In this talk, we propose a new problem, called Veracity, i.e., conformity to truth, which studies how to find true facts from a large amount of conflicting information on many subjects that is provided by various websites. We discuss a general framework for the Veracity problem which utilizes the relationships between websites and their information, i.e., a website is trustworthy if it provides many pieces of true information, and a piece of information is likely to be true if it is provided by many trustworthy websites. 個人簡介： Philip S.
