报告摘要: The Web contains a significantly amount of incorrect/untruthful/inaccurate data, which has caused problems and headache to Web users. The problem may occur in both structured and unstructured Web data. In this talk, I will report some of our recent works on analyzing the truthfulness of Web data. I will first report a survey on the quality of structured data in two domains: stock and flight. Then I will present some solutions to find truth from inconsistent data. Next I will discuss search-based techniques for determining the truthfulness of fact statements using the data on the Web. I will conclude the talk by briefly introducing some ongoing work and future directions in this area.
