In order to detect and recognise human activities, first of all, humans have to be monitored using sensors. The information grabbed by those sensors feed the modelling and inference layers, where the reasoning takes place. In this chapter, the most used inference and reasoning techniques have been introduced. Reasoning systems for AAL have been divided into three different categories, namely, the data-driven approach, the knowledge-driven approach, and the hybrid approach. The most representative examples of those approaches have been presented, describing the advantages and disadvantages. Due to the emergence of the Semantic Web and its application to AAL scenarios, has been devoted to describe the features of OWL and associated semantic reasoners, which can be classified as a knowledge-driven approach.}, booktitle = {Active and {Assisted} {Living}: {Technologies} and {Applications}}, publisher = {The Institution of Engineering and Technology}, author = {Azkune, Gorka and Ausin, David and Lopez de Ipina, Diego}, month = aug, year = {2016}, keywords = {AI for health, Artificial Intelligence, machine learning}, } ']

However, they present some disadvantages when it is necessary to deal with uncertainty, which is common in our daily life and affects the de- cisions that we take. To overcome this drawback, we have developed a novel framework to compute fact probabilities from the axioms in an OWL ontology. This proposal comprises the definition and description of our probabilistic ontology. Our probabilistic ontology extends OWL 2 DL with a new layer to model uncertainty. With this work we aim to overcome OWL limitations to reason with uncertainty, developing a novel framework that can be used in intelligent environments.}, booktitle = {{URSW} 2014 {Uncertainty} {Reasoning} for the {Semantic} {Web}}, author = {David Aus\xedn and Diego L\xf3pez-de-Ipi\xf1a and Federico Castanedo}, month = oct, year = {2014}, note = {00000}, keywords = {OWL, bayesian networks, intelligent environments, uncertainty} }']

An AAL environment could be modeled by ontologies and using a semantic reasoner as a way to infer knowledge about the underlying context. An important question is to clarify the feasibility of employing a semantic reasoner in AAL applications. For this reason, in this work we present our results of a simulated AAL environment using a knowledge driven approach. Our aim is to determine and clarify which combination of semantic reasoners and frameworks is the most convenient for this task. In particular, we are interested in the combination which provides a better computational performance and reasonable memory requirements. The obtained results show that the fastest choice under the employed dataset is to use the OWL API accessing the Pellet reasoner.
