In this paper, an algorithm for obtaining consistent answers to queries posed to inconsistent relational databases is presented. The algorith is proven to be sound, terminating and...
In this chapter, we summarize the research on querying inconsistent databases we have been conducting over the last five years. The formal framework we have used is based on two c...
Abstract. We present the Consistency Extractor System (ConsEx) that uses answer set programming to compute consistent answers to first-order queries posed to relational databases ...
We consider the problem of retrieving consistent answers over databases that might be inconsistent with respect to some given integrity constraints. In particular, we concentrate o...
A relational database is inconsistent if it does not satisfy a given set of integrity constraints. Nevertheless, it is likely that most of the data in it is consistent with the co...
