The usability of Web pages and applications is a fundamental factor in their success. Web designers are taking advantage of
the new technologies (scripting languages, Java, etc.) to increase the power, user friendliness and easiness of use of Web
pages.
This work presents two techniques that can be used to achieve this goal: the use of cognitive metaphors to build user interfaces,
and the use of Bounded Natural Language, to allow the user to express queries in an intuitive way.
