Abstract

The invention relates to methods and systems for providing interactive question-based applications over communication networks. According to the invention, information specifying questions and answers are stored in a first data unit, actions specifying how questions should be presented to users are stored in a second data unit, and rules specifying how presented material should be treated for display on different types of terminals are stored in a third data unit. This separation of content, functional logic, and presentation style simplifies the creation of new questionnaires and their delivery to different terminals over different communication networks.

12. A method according to claim 8, characterized in that the method further comprises the step of:

storing answers obtained as a result of displaying questions in a fourth computer-processable specification language.

13. A method according to claim 12, characterized in that said first, second, third, and fourth languages are defined in the XML language.

14. A method according to claim 1, characterized in that the method further comprises the steps of:

processing at least a part of a data unit of the first type according to at least a part of the definitions in a data unit of the second type for producing presentable questions,

processing said presentable questions according to at least a part of the definitions in a data unit of the third type for display on a specific type of terminal, and

transmitting processed presentable questions to a terminal of said specific type.

15. A method according to claim 1, characterized in that said method further comprises the step of:
