In data integration systems there is a problem of answering queries through a target schema, given a set of mappings between source schemas and the target schema, and given that th...
We present extended conceptual logic programs (ECLPs), for which reasoning is decidable and, moreover, can be reduced to finite answer set programming. ECLPs are useful to reason ...
