Valid or complete information in databases - A possibility theory-based analysis

Résumé

The validity of the information stored in a database may be guaranteed or not, according to the family of items which is considered. The information available in the database may be complete or not, as well, for a given type of items. The paper discusses how these forms of uncertainty can be represented in the framework of possibility theory, and how queries to a database where information is neither necessarily complete and nor valid, can be handled using possibilistic logic. One benefit of the possibilistic modelling is to allow for the use of graded levels of validity, and of graded levels of certainty that the information is complete.
