In this paper we introduce a logical query language extended with object-oriented typing facilities. This language, called DTL (from DataTypeLog), can be seen as an extension of Da...
The program TRANALYZE generates a gate-level representation of an MOS transistor circuit. The resulting model contains only four-valued unit and zero delay logic primitives, suita...
Forgetting irrelevant/problematic actions in a domain description can be useful in solving reasoning problems, such as query answering, planning, conflict resolution, prediction,...
We present a logic programming based dialogue system that enables the access in natural language to the heterogeneous external relational databases of the Évora University. The p...
