Semantic Enrichment of GSM-Based Artifact-Centric Models

Riccardo De Masellis, Domenico Lembo, Marco Montali, Dmitry Solomakhin
2014 Journal on Data Semantics  
We then discuss two scenarios of practical interest R. De Masellis that show how mappings can be used in the presence of multiple systems.  ...  For one of these scenarios we also describe a concrete instantiation of the framework and its application to a real-world use case in the energy domain, investigated in the context of the EU project ACSI  ...  the TBox is expressed in DL-Lite, and the mappings are GAV.  ...

Combining ontologies and statistics for sensor data quality improvement

Nina Solomakhina, Thomas Eiter
2014
The aim of this thesis is to propose a novel approach to address data quality issues in industrial datasets, in particular, measurements of sensors mounted at power generation facilities.  ...  In this work we represent domain knowledge in OWL ontology, which covers the topology of an industrial equipment and an information about measuring devices installed. Providing statistic [...]  ...  In both DL-Lite F and DL-Lite R data values are not considered, and hence attributes are dropped.  ...

Validation of ADOxx metamodels based on semantic technologies

Christos Lekaditis
2014 unpublished
In the same way that the model conforms to its metamodel, a metamodel must conform to its meta-metamodel.  ...  More specifically, a metamodel must always be in compliance with the rules enforced by syntax, and with the semantic constraints defined by semantics.  ...  .  OWL Lite is the sublanguage that stems from a further restriction of OWL DL to a subset of the language constructors.  ...
