New applications,developed by individual developers or small companies, can takeadvantage of both services and data already present on the Web.Data, produced by humans and machines, may be available indifferent formats and through different access interfaces. Thispaper analyses three different types of data available on theWeb and presents mechanisms for accessing and extracting thisinformation. The authors show several applications that leverageextracted information in two areas of research: recommendationsof educational resources beyond content and interactive digitalTV applications."
