Over the last decade or so, significant research has focused on defining Quality of Experience (QoE) of Multimedia Systems and identifying the key factors that collectively determine it. Some consensus thus exists as to the role of System Factors, Human Factors and Context Factors. In this paper, the notion of context is broadened to include information gleaned from simultaneous out-of-band channels, such as social network trend analytics, that can be used if interpreted in a timely manner, to help further optimise QoE. A case study involving simulation of cloud-based HTTP adaptive streaming (HAS) in a flash crowd scenario is presented with encouraging results. The paper then frames this approach in the context of Software Defined Networks (SDN) whereby all this network and end-user application/device information is gathered in a centralised manner and used for optimum decision making.

COBISS.SI-ID: 18967318The paper will present various solutions for content processing, which were developed at Institute of Electronics and Telecommunications at University of Maribor, Faculty of Electrical Engineering and Computer Science. The focus of the presentation is concentrated around the possibilities of using content processing in the scope of smart cities and communities, especially in the case of Smart Society initiative. Content processing is important to be able to cope with the increased amount of information, which results from the new ways of communication evolved in the last decade. Speech, sound, text, video and image are valuable sources of information in case of an emergency event. Content processing methods and projects presented are: automatic speech recognition, text to speech synthesis, acoustic detection, natural language processing and object detection.

COBISS.SI-ID: 19034390As part of co-operation in the Consortium for language resources and language technologies (KJVT) members of the research programme actively co-operated in the project of development of Modern Dictionary of the Slovene Language (http://www.cjvt.si/sssj/). This projects is important for our research group as it considers the needs of language technologies for dictionary data (such as morphology, phonology, semantics). The basic activity of this project in the year 2015 was to prepare the concept for new dictionary. As part of this activity, we co-ordinated the group in the field of speech and we carried out a number of basic research on the topic of including speech data in the dictionary description. As an overview on the research done within the project the monography 'Slovar sodobne slovenščine: problemi in rešitve' was published at the end of 2015. Our research group published part of the results in this monography, while other results were publish or are to be published in other publications as well.

COBISS.SI-ID: 19081750An analysis of the effect of a nonstandard clear-channel assessment (CCA) interval in IEEE 802.15.4 nonbeacon-enabled networks consisting of nodes which send one packet to a sink and are partially hidden from the others is presented. By using the statistical model-checking capability of the PRISM model checker, we have obtained probabilities of successful sending and analysed the differences between the results for the standard and nonstandard CCA intervals.
