Abstract

In many applications users need a more sophisticated access than the direct answer to a query. We say the access to a Data and Knowledge Base is cooperative if the system offers new functionalities, with respect to question answering, and/or if the system can adapt the answers to each particular user, or class of users.

New functionalities involve, among others:

• extended answers containing additional facts neighbour to the direct answer, or relevant to the query,
• explanations, which are formulas giving the reason why an answer is empty or giving properties held by every tuple in the direct answer,
• intentional answers which are formulas defining the answer independently of a particular state of the Database,
• conditional answers providing, in the context of incomplete information, the conditions which guarantee a tuple is in the answer.
