English abstract:
This tutorial, which is a continuation of the tutorial "Datalog and Its Extensions for Semantic Web Databases" presented in the Reasoning Web 2012 Summer School, discusses recent advances in the Datalogą family of languages for knowledge representation and reasoning. These languages extend plain Datalog with key modeling features such as existential quantification (signified by the "+" symbol), and at the same time apply syntactic restrictions to achieve decidability of ontological reasoning and, in some relevant cases, also tractability (signified by the symbol "−"). In this tutorial, we first introduce the main Datalogą languages that are based on the well-known notion of guardedness. Then, we discuss how these languages can be extended with important features such as disjunction and default negation.
