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).

Visiting Professor: Markus Zanker, Free University of Bolzano, Italy

Professor Markus Zanker from the Free University of Bolzano, Italy will visit the Faculty of Informatics in the summer term 2016.

He will give the course "195.064 VU Recommender Systems" in which the scientific underpinnings of the field of Information Filtering and Recommender Systems will be presented. Recommender systems are now largely used, particularly in eCommerce web sites, for easing the information search and discovery processes, and increasing customer fidelity and conversion rates. Starting from basic information retrieval concepts more advanced techniques for information filtering and decision support in recommender systems will be investigated, such as those exploiting contextual information or supporting decisions taken by groups. The students will be provided with a rich and comprehensive catalogue of information search tools that can be exploited in the design and implementation of a specific Web site, such eCommerce or eGovernment applications for travel, tourism or health. Many open issues will be described, motivating and promoting new research activities. At the end of the course every student will produce a research report describing a novel information filtering and recommendation task and illustrating a novel and viable technology for addressing such task.

26-29 April: lectures and excercises
31 May and 1 June: lectures and students' presentation

The course is for master and PhD students.

PhD Defense: Soodeh Farokhi

We are happy to announce that Soodeh Farokhi has successfully defended her PhD thesis on Thursday, 21 January. The title of her thesis is "Quality of Service Control Mechanisms in Cloud Computing Environments", please find the abstract here.

New diploma topic: "Classifying e-Tourism data sets"

The scope is to apply machine learning to classify e-tourism data sets. These sets are hotel descriptions, each description consisting of a set of given attributes (usually Boolean attributes following a well known and given data standard) and probably a free text. In a first step, these descriptions need to be analyzed and harmonized (on a semantic/conceptual as well as schema level). In a next step the tourism objects need to by classified, using both the set of attributes as well as the textual descriptions. Using machine learning these hotels should be classified into 7 distinct classes. Web Services should be developed to demonstrate the proof-of-concept. The evaluation is based on real world data.
Thorough skills in machine learning, Java and Web Services are required.
If you are interested, please contact the secretary of the EC-group.

Visiting professor: Tsvi Kuflik (University of Haifa/Israel)

Professor Tsvi Kuflik from the University of Haifa, Israel, is visiting our group from 16 September to 16 November 2015. He will give a talk at Zemanek Seminarraum (TU Wien) on Wednesday, 4 November 2015 at 5 PM titled "The museum as a living lab — A case study for using mobile technology for inferring social aspects in the museum".

Biography of Prof. Kuflik:
Prof. Tsvi Kuflik heads the Information Systems Dept. at The University of Haifa. Over the past ten years, the focus of his work was on ubiquitous user modeling applied to cultural heritage. In the course of his work, a “Living Lab” has been developed at the University of Haifa – a museum visitors’ guide system was developed for the Hecht museum. It is available for visitors on a daily basis and serves also as a test bed for experimenting with novel technologies in the museum. Currently, the system is being used for research on Social Signal Processing where signals transmitted by devices carried by the visitors are used for modeling group behavior, in order to reason about the state of the group visit. Another research direction focusses on the use of intelligent user interfaces in ubiquitous computing within the “living lab”. Where issues like interaction with large, situated displays; interrupt management; navigation support; temporal and lifelong aspects of ubiquitous user modeling are studied. Tsvi got BSc. and MSc. In computer science and PhD. In information systems from Ben-Gurion University of the Negev, Israel. Over the years Tsvi collaborated with local and international researchers, supervised graduate students working with him on this research, organized the PATCH workshops series (Personal Access To Cultural Heritage) and published about 200 scientific papers, out of them 30 papers about this specific research. Tsvi is also a distinguished ACM scientist and a senior IEEE member.

IFS represents Austria at the European Linked Data Contest

The European Linked Data Contest [1] has been organised with the goal of showcasing the European scene in the area of Linked Data and Semantic Web technologies. The contest awarded prizes for the best projects that make use of Linked Data, either in an open Web sitting (Linked Open Data category) or within organisations (Linked Enterprise Data category). Similarly to the Eurovision contest, finalist projects were selected from each European country and then the winners were selected from these finalists through the vote of an international jury.

The competition attracted 53 submissions from 22 countries. The finalists for Austria, for both categories, were Linked Data applications created within IFS by a group of researchers at the Christian Doppler Laboratory „Software Engineering Integration for Flexible Automation Systems“ (CDL-Flex) [2]. Under the supervision of Dr. Marta Sabou, the team submitted two applications. In the area of Linked Enterprise Data, the team showcased their ongoing work on the AutomationML Analyzer [3], an output of research that explores the use of Semantic Web and Linked Data technologies in the Industrie 4.0 area. In the Linked Open Data category, the team submitted the OGD Apps Observatory [4], which exposes as Linked Data metadata about applications created with Open Data from Stadt Wien. The observatory also provides an appealing visual interface to support the analysis of this metadata.

As of January 2016, the OGD Apps Observatory also features as one of the open data applications on the official open data portal of the Austrian government, data.gv.at [5].

We are pleased that through these submissions work performed at TUWien, and especially at IFS, was put on the map of European Linked Data research.
