Abstract. Ontologies are one of the core foundations of the Semantic Web. To participate in Semantic Web projects, domain experts need to be able to understand the ontologies involved. Visual notations can provide an overview of the ontology and help users to understand the connections among entities. However, the users first need to learn the visual notation before they can interpret it correctly. Controlled natural language representation would be readable right away and might be preferred in case of complex axioms, however, the structure of the ontology would remain less apparent. We propose to combine ontology visualizations with contextual ontology verbalizations of selected ontology (diagram) elements, displaying controlled natural language (CNL) explanations of OWL axioms corresponding to the selected visual notation elements. Thus, the domain experts will benefit from both the high-level overview provided by the graphical notation and the detailed textual explanations of particular elements in the diagram.

The mobile conquers the world. The need in a comprehensive and systemized multiedge testing approach is rising along with mobile apps becoming even more complex. As a leader in enterprise market, Apple iOS has been chosen as a target mobile platform for the study. The authors have investigated aspects that influence functional testing of iOS apps in particular, and mobilein general. The study also exposes the security capabilities and risks that often are not mitigated in favor of time to market rush. Investigation and clustering of mobile UI test automation tools is performed. The capabilities and limitations of Apple UIAutomation are discovered. Solutions aimed at overcoming the limitations of out of the box UIAutomation are united in tTap framework developed by the authors. In conclusion an ideal cross-platform mobile UI test automation tool is proposed.
