We consider a situation in which a humanoid robot must reach a goal region (walk-to task) walking in an environment consisting of horizontal patches located at different heights (world of stairs). To solve this problem, the paper proposes an integrated motion planner/controller working in two...

We study the problem of designing reverse engineering techniques for associating semantic descriptions to existing data services. We base our proposal on the Ontology-Based Data Access paradigm, where a domain ontology is used to provide a semantic layer mapped to the data sources of an...

It is well-known that answering conjunctive queries with inequalities (CQ≠s) over DL-LiteR ontologies is in general undecidable. In this paper we consider the subclass of CQ≠s, called CQ≠,bs, where inequalities involve only distinguished variables or individuals. In particular, we tackle the...
