An important application of semantic technologies in industry has been the formalisation information models using OWL 2 ontologies and use RDF for storing exchanging data. Moreover, legacy data can be virtualised as following ontology-based ac cess (OBDA) approach. In all these applications, it is to provide domain experts with query formulation tools expressing their needs terms queries over ontologies. this work, we present such a tool, OptiqueVQS, which designed based on our experience...
Here, we combine international air travel passenger data with a standard epidemiological model of the initial 3 mo COVID-19 pandemic (January through March 2020; toward end which entire world locked down). Using information available during this phase pandemic, our accurately describes main features actual global development demonstrated by high degree coherence between and data. The validated allows for an exploration alternative policy efficacies (reducing and/or introducing different...
An increasing number of sensors are being deployed in business-critical environments, systems, and equipment; stream a vast amount data. The operational efficiency effectiveness business processes rely on domain experts' agility interpreting data into actionable informatio n. A expert has extensive knowledge but not necessarily skills databases formal query languages. Therefore, centralised approaches often preferred. These require IT experts to translate the information needs...
Modeling concurrent systems and testing multi-threaded implementations against the model is an exciting field of study. This paper presents work done on constructing executing test cases for industrial-size application a written in Creol modeling language. Models Creol, object-oriented, language, can be structurally similar to finished implementation; we show how keep this desirable property when re-using models as oracles. Also, conformance relation between system under that needs less...
