Ontology-based Software Architecture Documentation by Dr. Peng Liang

Speaker: Dr. Peng Liang, Free University Amsterdam, the Netherlands
Slides: Ontology-based Software Architecture Documentation

Abstract. A common approach to software architecture documentation in industry projects is the use of file-based documents (e.g., Word documents). This documentation approach offers a single-dimensional perspective on the software architectural knowledge contained. Knowledge retrieval from file-based architecture documentation is efficient if the perspective chosen fits the needs of the readers; it is less so if the perspective does not match the needs of the readers. In this talk, I will describe an approach we developed aimed at addressing architecture documentation retrieval issues. We employed software ontology in a semantic wiki optimized for architecture documentation. We also evaluated this ontology-based documentation approach in a controlled industry experiment involving software professionals. The efficiency and effectiveness of the proposed approach is found to be better than that of the traditional file-based approach.

The Smart Grid’s Big Data Generating Potentials by Prof. Marco Aiello

Speaker: Prof. Marco Aiello, University of Groningen, the Netherlands
Slides: The Smart Grid’s Big Data Generating Potentials

Abstract. The Smart Power Grid promises to not only provide for a more reliable distribution infrastructure, but also give the end-users better pricing, information, and freedom. The promise is fuelled by a pervasive digitalization of the energy production and distribution network that will finally involve utilities, governments, and end-users. The real advantages of the smart grid will be available to all, only if the physical infrastructure of energy distribution is supported by adequate information systems. In this talk, I will review the current state and possible evolutions of the concept of a smart grid, I will point to the (big) data that future information systems will need to manage and, finally, indicate possible uses for such information.

Image Quality Assessment by Prof. Xinbo Gao

Speaker: Prof. Xinbo Gao, Xidian University, China

Slides: Image Quality Assessment

Abstract. With the development of imaging technologies, visual information, recorded by images and videos, has become the main source for knowledge acquisition. In the process of image acquisition, processing, transmission, and storage, some artefacts or noise maybe introduced to images, which will degrade the visual quality. To improve the performance of image processing, it is necessary to assess image quality. Therefore, image quality assessment (IQA) is the prerequisite and foundation of imaging or image processing system optimization. The objective of IQA is to provide computational models to measure the perceptual quality of a given image. Recently, a large number of methods have been designed to evaluate the quality of images. In this talk, I will introduce some popular IQA metrics, especially several IQA metrics proposed by my group. They are organized into 3 categories, full-reference metrics, reduced-reference metrics and no-reference metrics.
