An Analysis of Structured Data on the Web
In this paper, the authors analyze the nature and distribution of structured data on the Web. Web-scale information extraction, or the problem of creating structured tables using extraction from the entire web, is gathering lots of research interest. They perform a study to understand and quantify the value of Web-scale extraction, and how structured information is distributed amongst top aggregator websites and tail sites for various interesting domains. They believe this is the first study of its kind, and gives users new insights for information extraction over the Web.
