188/4 Electronic Commerce Group
E-business, e-commerce and underlying technologies did not only change our economy and businesses, but society as a whole. They induce rapid changes in our economic and social processes. Consequently, the E-Commerce group follows a more encompassing approach, starting from research in specific Informatics areas over analyzing and modeling enterprises and their respective processes to looking at entire market structures. In addition, it also looks at ways to foster innovation and the creation of new ideas in this e-commerce arena.
The e-commerce group performs research 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 consequently the specification and implementation of e-business systems, (ii) ontology engineering and information integration, (iii) cloud computing and resource allocation. In the B2C domain, the group does research in (i) text/content mining, data analytics and network analysis, and ii) personality based recommender systems combined with visual interaction paradigms. In this context a dominant application domain is the area of e-tourism.
Enormous amounts of data are permanently generated by customers of telecommunication services and their interactions. These data can be used to provide personalized recommendations of mobile services. In this master thesis a comprehensive user model for such a recommender system will be developed. The aim is to identify appropriate features that can be utilized within sophisticated recommendation approaches. These features will be obtained by studying the state-of-the-art in this field as well as by conducting empirical analyses of existing data of an Austrian Telco.

In the travel domain recommender systems are confronted with specific challenges, as the tourism product is usually very complex. Travelling can be seen, moreover, as an emotional experience. Therefore comprehensive user models are required. In this master thesis a seven-factor model will be considered, where each user is described with respect to seven basic travel behavioral patterns that also account for the personality of a user. These factors span, moreover, a seven-dimensional vector space.
The role of universities and of computer science in the European crises of refugees is discussed in an article in the October issue of the Communications of the ACM. The accompanying video addresses particularly the project Welcome.TU.code, which was co-initiated by Prof. Hannes Werthner, the head of the EC group.
The head of the EC group Prof. Hannes Werthner and EC group members Julia Neidhardt and Amra Delic had a number of contributions at this year’s 10th ACM Conference on Recommender Systems (RecSys), which took place at the Massachusetts Institute of Technology (MIT) in Cambridge, MA, USA from September 15th to September 19th 2016. The Workshop on Recommenders in Tourism at RecSys was co-organized by Julia Neidhardt. At this workshop, Prof.
