  1. Quality of web documents

  2. Which documents to trust? • The problem of recognition of quality documents, that could be trusted, among billions of web documents is acute. • No simple and standard mechanism, that would enable us to recognise good documents, exists. • No institution, that would do such work for us to a great extent and fast enough, exists. • Sometimes the decision will be based on a set of simple, but vague rules and some intuition. Alpe Adria Master Course :: Medical Informatics :: Dr. J. Dimec: Quality of web documents.

  3. Which documents to trust? • There is no problem with documents that are digitalised versions of paper documents and we would trust paper originals. • However, are these documents really what they seem to be? It is easy to forge the document on a normal academic server, but such misconducts are rare. Alpe Adria Master Course :: Medical Informatics :: Dr. J. Dimec: Quality of web documents.

  4. Which documents to trust? • With other documents the user should use similar mechanisms as in paper world: • search for the description of peer-review policy, especially in e-journals; • use documents that came from respected academic institutions; • use documents that are being pointed to by respected researchers or research groups; • use documents that are part of respected digital library with well-defined collection policy.
