Data mining of microarray data more often includes exploration of temporal data. E.g., researchers might look for temporal changes in gene expression to determine responses to an injury. Knowledge-based Temporal Abstraction does not assume that the pattern of time points is similar to the original experimental design. We extended this framework by creating an software tool using open-source pla...

Nowadays, vital signs monitoring with mobile devices such as smartphones and tablets is possible through Bluetooth-enabled biometric devices. In this paper, we propose a system to monitor the risk of cardiovascular diseases in Ambient Assisted Living environments through blood pressure monitoring and other clinical factors, using mobile devices and reasoning techniques based on the Systematic C...

Introducing the dimension of time in ontologies turns binary relations into ternary which cannot be handled by OWL. Approaches such as the N-ary relations or the 4D-fluents approach discussed in this work, offer satisfactory solutions to this problem. However, data and property semantics are not preserved in the resulting representations nor can they be handled by ordinary reasoners such as Pel...

We show that the semantic formal model for Open Digital Right Language (ODRL)-based rights delegation policies can be enforced and expressed as a combination of ontologies and rules, e.g., Semantic Web Rule Language (SWRL). Based on ODRL’s expressions and data dictionary, a rights delegation ontology is proposed in this study. Furthermore, we express the rights delegation policy as a set of ont...

Representing the semantics of the interaction of two or more tolerances (i.e. composite tolerance) explicitly to make them computer-understandable is currently a challenging task in computer-aided tolerancing (CAT). We have proposed a description logic (DL) ontology based approach to complete this task recently. In this paper, the representation of the semantics of the composite positional tole...

The representation of temporal information has been in the center of intensive research activities over the years in the areas of knowledge representation, databases and more recently, the Semantic Web. The proposed approach extends the existing framework of representing temporal information in ontologies by allowing for representation of concepts evolving in time (referred to as “dynamic” info...

Abstract The COVID-19 pandemic has flooded a vast amount of information into the world. To help control this situation, good utilization overflow in data is required. However, come different forms, posing numerous challenges subsequent processing. Therefore, uniform knowledge representation needed, and ontology can play role. will model patient healthcare-related data, ranging from symptoms to ...

Changes in the information age have induced necessity for a more efficient and effective self-decision-making requirement. A method of extracting constructing naval operations decision-making rules based on scenario analysis is proposed. The template specifications Event Condition Action (ECA) are defined, consistency detection ECA SWRL logical relationships state transitions operational proces...

This paper presents our experience regarding the creation of 3D semantic facility model out of unorganized 3D point clouds. Thus, a knowledge-based detection approach of objects using the OWL ontology language is presented. This knowledge is used to define SWRL detection rules. In addition, the combination of 3D processing built-ins and topological Built-Ins in SWRL rules aims at combining geom...
