ecosioSolutions for the exchange of electronic documents
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).
Next year IFITT organizes the 20th ENTER conference. The eCommerce group has always taken a significant role in the establishment of this conference - particularly, Prof. Hannes Werthner who will be giving a keynote "Reflection on 20 years of eTourism and thoughts for the future". Moreover, our colleague Julia Neidhardt is featured in the newsletter of IFITT as a prominent PhD student in the areas of Web Science and eTourism.
Classifying and mapping e-Tourism data sets
The scope of the thesis is to apply text mining techniques to classify e-tourism data sets. These sets are hotel descriptions, each description consisting of a set of given attributes (usually Boolean attributes following the so-called GIATA standard) and 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. In the latter case text mining techniques should be applied. In a final step these classified tourism objects should be mapped to the “harmonized” data schema. In such a way objects can be easily exchanged between different parties. Web Services should be developed to demonstrate the proof-of-concept. The evaluation is based on real world data. Thorough skills in text mining, Java and Web Services are required. Co-supervisor: Dr. Rainer Schuster.

Over 60 percent of Internet users worldwide start planning their next trip by typing one or more destinations into their search engine. Yet according to recent studies, 500 million would-be travelers are not sure where they want to go or what they want to do. The newly-launched travel community platform Pixmeaway solves this problem by offering the world's first image-based travel search engine.
The project team members of the ERPEL project are launching their start-up in the area of e-Invoicing. The company provides an infrastructure tailored to the specific needs of SMEs in this area. Thereby, it especially focuses on lowering the barriers of interoperability between enterprise information systems enabling an out-of-the-box processing of structured business documents across different software vendors.
The new Doctoral College of Environmental Informatics is now funded by TU-Vienna. The consortium comprises 10 key faculty members from 7 institutes. From our institute, Prof. Silvia Miksch and Prof. A Min Tjoa are involved.

In recent years, Environmental Informatics has emerged as a new interdisciplinary research field that can facilitate decisions regarding social, economic, ecological, and environmental goals based on a variety of information technology measures. This Doctoral College aims to promote the objectives of Environmental Informatics in one of the research focus points of the Vienna University of Technology, "Energy and Environment".
Our proposal entitled "Benchmark DP" is accepted in context of Information and Communication Technology Call 2012. Here is a short abstract:
Abstract: Recurrent reports and personal experiences of unaccessible digital information are making us painfully aware how short-lived the digital world is. Digitally encoded information often does not survive its originating environment. Digital Preservation, which aims to ensure digital longevity, has emerged as a key challenge to Information Systems. Yet, the discipline is held back by a lack of systematic approaches to assess, compare and improve methods, tools and processes to ensure digital longevity over time. There is no way to assess and compare information renderings, systems, processes and organisations with objective, quantified and standardised means. Such systematic benchmarking, however, is the fundamental enabler of systematic improvement. Benchmark DP proposes an innovative approach to advance the capacity for digital longevity by creating frameworks and quantitative benchmarks in the dimensions of information, IT processes, and engineering approaches.

Our proposal entitled "Formalizing Information Security Risk and Compliance Management" is accepted in context of Information and Communication Technology Call 2012. Here is a short abstract:
Abstract : Since the vast majority of business decisions is based on data, reliable information technology is a prerequisite for business continuity and, therefore, crucial for the entire economy. Legal and regulative frameworks demand decision makers to define mitigation strategies for their operational IT risks, but existing approaches fall short of meeting their needs. Recent studies have shown that the lack of IS knowledge at the management level is one reason for inadequate or nonexistent IS risk management strategies. This project pursues to close this essential research gap by providing a new approach to support decision makers in interactively defining the optimal set of security controls according to common regulations and standards. The proposed project addresses three essential yet unsolved research problems, namely (i) the formal representation of IS standards and domain knowledge, (ii) the reliable determination of the risk, (iii) and the (semi-) automatic countermeasure definition.
