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).

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.

Social Network Analysis course by Noshir Contractor

Noshir Contractor will give a course on Social Network Analysis at Vienna University of Technology in June. Noshir Contractor is Professor for Behavioral Sciences at Northwestern University, USA and has also a strong technical background. He is one of the leading and most renowned researchers in this field. In 2013 our colleague Julia Neidhardt spent several months as a visiting scholar in his lab.

The course will take place full-day on June 8th, 9th, and 10th. Noshir Contractor is invited by the Vienna PhD school of informatics and the course is open to interested PhD and master students. Further information can be found in TISS.

Siegfried Mattl (1954-2015)

We are deeply saddened to announce the passing of our dear friend and collaborator Siegi Mattl, the head of the Ludwig Boltzmann Institute for History and Society. In the last decades, the Web has also changed how research in the humanities and the social sciences is done. Siegi, who was a progressive and visionary scientist, was aware of this much earlier than many others. Critically reflecting, he actively shaped and designed the research approach in the field humanities. This led to interesting interdisciplinary collaborations, also with our research group. Our last common project, the Vienna Summer School on Digital Humanities, will take place in July this year. Siegi, we will miss you!
