Applications of smart environments are ever-increasing due to their possibilities of contributing towards an independent and active lifestyle for different user groups. An example of such an application can be found in health-care, where an elderly can be unobtrusively monitored and cared for in their own home. In this paper, we give a description of how qualitative spatio-temporal reasoning can be used to create services for the inhabitants of a sensorized home, with an emphasis on elderly…

### An Incremental SAT-Based Approach to Reason Efficiently on Qualitative Constraint Networks

• Computer Science
CP
• 2018
This article proposes an incremental $$\mathrm {SAT}$$-based approach for providing a framework that reasons about the RCC language in a counterexample-guided manner and restricts ourselves to QCNs that, when satisfiable, are realizable with rectangles.

### Tractable Fragments of Temporal Sequences of Topological Information

It is shown that there is no Cartesian subclass containing all the basic relations and the universal relation for which the algebraic closure decides satisfiability, and some tractable subclasses are identified by giving up the relations containing the non-tangential proper part relation and not containing the tangential proper parts relation.

### Minimality of Combined Qualitative Constraint Networks

It is proved that the topological temporal sequences of constant-size regions over the subclass SRCC8 check this property, and the complexity of the satisfiability decision of relations as well as the enumeration of satisfiable basic relations is studied.
