  4. Why? • Web content is currently formatted for human readers rather than programs • HTML is the predominant language in which Web pages are written (directly or using tools) • Vocabulary describes presentation

  6. HTML? • Inability to cover any content aspects – HTML only describes the appearances of documents and cannot cover any content related aspects. It is therefore unsuitable for explicit queries. • Inability for semantic markup– Individual elements on a page cannot be marked semantically.

  7. Why does this happen?? • The Web content is not machine-accessible • lack of semantics • Not in a proper structure • Not in a machine understandable manner • keyword-based search engines • (e.g. Google, AltaVista, Yahoo)

  8. How to overcome these limitations • Currents situation can be improved by adopting following two strategies • Use the content as it is represented today, and to develop techniques based on artificial intelligence and computational linguistics. • This approach has been followed for sometime now, but despite advances that have been made the task still appears too ambitious. • Represent Web content in a form that is more easily machine processable • Then use intelligent techniques to take advantage of these representations (Semantic Web).
