Active Research Projects
[2018-2021] FWF SEPSES – Semantic Processing of Security Event Streams
The SEPSES project aims to tackle challenges in the IT security domain by applying an innovative interdisciplinary approach at the intersection of state-of-the-art semantic technologies and security research. It will thereby bring meaning to disparate log data and make security information machine-interpretable in (near) real-time. To resolve ambiguous representations, we will develop ontologies and ontology design patterns and leverage the resulting uniform conceptual model to semantically lift heterogeneous security data from various sources. By making security event information universally comprehensible, it will become possible to link security events with background knowledge and process the semantically enriched security event streams to automatically identify logical connections between events. To express such logical connections in an abstract manner, we will develop a semantic modeling approach for attack patterns. The explicit semantics will allow RDF stream processors to reason over incoming event streams in order to identify suspicious activities. To address the dynamic nature of the security domain, we will develop discovery techniques to identify emerging patterns of attack.
[2017-2020] FFG CitySPIN – Cyber-Physical Social Systems for City-Wide Infrastructures
The CitySPIN project aims to create a platform for cyber-physical social systems in order to facilitate innovative Smart City infrastructure services. The project is at the forefront of cyber-physical systems research and aims to extend those systems with a social dimension (i.e., cyber-physical social systems).
CitySpin is an Austrian research project funded by the Austrian Federal Ministry of Transport, Innovation, and Technology (BMVIT) and the Austrian Research Promotion Agency (FFG) under the program “ICT of the Future”. The CitySPIN project starts in October 2017 with a duration of 30 months and a project consortium that consists of TU Wien, WU Wien, Wiener Stadtwerke, and Semantic Web Company.
[2018-2019] FFG EXPEDiTE – “EXPloring opportunities and challenges for Emerging personal DaTa Ecosystems: Empowering humans in the age of the GDPR – A Roadmap for Austria”
In the EXPEDiTE project, we will explore challenges, barriers, and drivers for the emergence of human-centered personal data ecosystems. Furthermore, we will investigate how individuals — once they become able to acquire their personal data – can integrate and analyze it. To this end, we will explore the concept of context-rich personal knowledge graphs that “liberate” data from closed environments, link and enrich it with other available (e.g., open) data, and create insights and value from individuals’ previously dispersed data. Additionally, such graphs have the potential to facilitate innovative products and services without locking individuals into proprietary environments. In this project, we will tackle key technical challenges involved in realizing this vision, including technical interfaces, syntactic and semantic interoperability, and mechanisms that allow users to share data, exercise control over its utilization and automatically manage consent for the use of their data. The project results will feed into a comprehensive roadmap that will assess the current state of personal data ecosystems in Austria and in the broader international context, synthesize the major challenges and opportunities they face, and outline a path towards human-centered personal data ecosystems.
Past Research Projects
[2018-2019] FFG SEMCON – Semantic Container for Data Mobility
Semantic Containers are designed to support and facilitate data exchange between multiple parties. Essentially, each Semantic Container (SemCon) provides the ability to (i) accept input data, (ii) validate and provision data with necessary information, e.g., usage policy and provenance, (iii) record datahashes in a distributed ledger for immutability, (iv) store data, and(v) distribute output data to users. In addition, SemCon provides an optional (vi) billing service mechanism to facilitate transaction over data exchange.
[2012-2016] CDL-Flex – Christian Doppler Laboratory “Software Engineering Integration for Flexible Automation Systems” (CDL-Flex)
The general scope of research in the CDL-Flex is the analysis, automation, and improvement of software and systems engineering processes for complex software-intensive automation systems (AS), such as industrial production plants. Software and systems engineering projects in the context of the CDL-Flex aim at producing software-intensive automation systems and involve several engineering disciplines, such as automation process, mechanical, electrical, and (automation) software engineering. In such a software and systems engineering environment, the work of software engineers depends on the inputs from other engineering disciplines, e.g., requirements, process specification, and design constraints incorporated in a range of engineering models.
