188/4 Electronic Commerce Group

E-Business and E-Commerce include, besides other influencing domains, rapid changes to economic and social processes. For this reason, the E-Commerce group pursues taking an encompassing view at such processes reaching from analyzing enterprises and their respective processes to evaluating the entire market, as well as is active in creating ideas and solutions for meeting the demands of the respective stakeholders.

Overall, the E-Commerce group performs research and creates solutions in the Business-2-Business (B2B) and Business-2-Consumer (B2C) domains. In the B2B domain, the group focuses on (i) business (process) modeling and definition and consequently the specification and implementation of e-business systems while considering and contributing to semantic web research and service-oriented architectures, (ii) ontology engineering and information integration, (iii) "Web Science" focusing on network analysis and content as well as text mining. In the B2C domain, the E-Commerce group performs research targeting (i) visual interaction paradigms as well as (ii) mobile applications. Thereby, our group focuses especially on the development and application of our research in the area of e-tourism and its mobile applications.

Parts of the EC group are working on systems based research, namely on virtualized HPC systems, massive-scale data analytics and energy efficient ultra-scale distributed systems. Our goal thereby is to develop speculative methodologies and techniques to allocate resources in an energy efficient way, but at the same time meet requirements of the end users, like the certain latency of the applications. Our approaches are evaluated quantitatively on different scales by simulations, benchmarks or on experimental clusters. We strive to develop generic methods and methodologies but we let our research be inspired by a set of real world applications from different domains like life science (e.g., DNA sequencing) or social media (e.g., Facebook size data centers).

At the 20th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA) 2015 Luca Berardinelli, Stefan Biffl, Emanuel Mätzler, Tanja Mayerhofer, and Manuel Wimmer received the Best Paper Award in Factory Automation for their paper on "Model-Based Co-Evolution of Production Systems and their Libraries with AutomationML."

Welcome.TU.code: Computer Science-Workshops for young refugees

In July and August 2015 a team of students and professors of the faculty of informatics (among them the head of our group, Prof. Werthner) initiated the project Welcome.TU.code. The aim of the project was to organise computer science workshops for unattended underage refugees at the TU Wien. More than 80 refugees in the age between 14 and 18 years registered for the courses and made their first steps in programming simple applications and games.

Below you can see photos of the farewell party at the end of the workshops.

9th ACM Conference on Recommender Systems organized by the E-Commerce Group

The E-Commerce Group organizes the 9th ACM Conference on Recommender Systems (RecSys '15), which will take place at TU Wien (Freihaus) from September 16-20, 2015.

The ACM Recommender Systems conference is the premier international forum for the presentation of new research results, systems and techniques in the broad field of recommender systems. Recommendation is a particular form of information filtering, that exploits past behaviors and user similarities to generate a list of information items that is personally tailored to an end-user’s preferences. As RecSys brings together the main international research groups working on recommender systems, along with many of the world’s leading e-commerce companies, it has become the most important annual conference for the presentation and discussion of recommender systems research. RecSys 2015, the ninth conference in this series, will be held in Vienna, Austria. It will bring together researchers and practitioners from academia and industry to present their latest results and identify new trends and challenges in providing recommendation components in a range of innovative application contexts. In addition to the main technical track, RecSys 2015 program will feature keynote and invited talks, tutorials covering state-of-the-art in this domain, a workshop program, an industrial track and a doctoral symposium.

Tourist Attraction Recommendations for Vienna: Participate in research ...

... and get to know your personal top 10 attractions for your next journey to Vienna. The aim of this project is to evaluate an online recommendation application

which helps tourists visiting Vienna to select attractions which are best tailored to their personal needs.

We would very much welcome your assistance in testing the application by selecting your personal top 10 attractions and completing afterwards the questionnaire which can be found at the application website.

FWF START grant awarded to Ivona Brandic

We are very happy to announce that Ivona Brandic was awarded with an FWF START grant!

The goal of the project is, according to the FWF, to give young and outstanding researchers the long-term and extensive financial security to plan their research and to build up or consolidate their own research groups thereby qualifying themselves for senior scientific positions (especially as university professors within Austria or abroad).

Ivona Brandic is one of only about 7 resarchers who were given this opportunity. The EC-group congratulates her on this great achievement!

PhD Defense Nataliia Rümmele

We are glad to announce that Nataliia (Pobiedina) Rümmele has successfully defended her PhD thesis "Temporal link prediction using graph pattern matching" on Tuesday, 2 June 2015. For abstract please click here.

New Master Thesis topic offered by Hannes Werthner in cooperation with the Verein für Konsumenteninformation (VKI)

The scope of the thesis is an Analysis and Design of an Information System for the Verein für Konsumenteninformation (VKI) and includes an analysis of processes (from searching the information to the publication) and data sources as well as a conceptual design of an IS-Architecture for the VKI. The aim is a multipublication strategy to successfully position the VKI on the electronic information market. The work will be done in close cooperation with the VKI and the final result will be presented to the VKI board of directors.
