摘要

It is now recognized that querying databases containing imprecise information raises several problems, including that of the computational complexity of evaluating the query. In this paper, we consider a new kind of query, called possibilistic query, of the form "to what extent is it possible that a given tuple t belongs to the answer of Q", where Q is a regular relational query. The aim is to show that a reasonable complexity can be expected for a specified subset of possibilistic queries.
