Research Team I2S

Intelligent Information Systems


Since 1999, the I2S research team performs application-oriented research and development of intelligent information systems in the Internet and Web. Main focus is on the application of Artificial Intelligence (AI), Agent Technologies, Services Computing, and Semantic Technologies for innovative means of intelligent data analysis and service coordination.

Vision:  Agents and semantic technologies, each with deep roots in AI, together with services computing are commonly considered as key enablers for the development of intelligent information systems in the future Internet. The future Internet is expected to arise from the ongoing convergence of the Internet of Services (IoS), the Internet of Things (IoT), the Internet of Interaction, and the Quantum Internet. Intelligent information systems in the future Internet are envisioned to provide users with assisted real-time access to relevant data and service coordination anywhere, anytime, on any device, to anyone, safe and secure, and in an intelligent way. Agent technologies for individual or joint AI planning and learning, inter-agent communication and coordination can be used to implement autonomous, proactive, rational, adaptive and collaborative behaviour of such systems with intelligent agents. Semantic technologies enable the semantic interoperation and coordination of distributed heterogeneous data, services, and processes by these agents for intelligent information systems in support of industry and business, as well as our private and social life.

Research: Research of the I2S team on intelligent service coordination addresses  the challenges of scalable, flexible, situatively optimal and high-performance semantic service discovery, composition planning and execution by intelligent agents in dynamic and distributed environments. In case of contested or chargeable data and services, the agents may also have to enter rational and trusted negotiations (bargaining, coalition formation, auctions) in order to resolve the conflicting goals with maximized individual or social welfare of the respective multi-agent system. Research of the I2S team on intelligent data analysis currently addresses the challenges of scalable, qualitative data stream analysis (hybrid semantic stream reasoning) and semantic explanations of results to users, as well as hybrid (deep) learning and planning for scene understanding and safe navigation of autonomous cars.

Applications:  The research results of the I2S team are implemented in a wide range of free open-source and partly awarded tools and benchmarks for semantic service coordination and data analysis, as well as in prototypes of intelligent information systems for various application sectors. These sectors include

  • medical emergency assistance services in health care
  • smart event management and social media
  • decentralized power regulation in smart micro-grids
  • agricultural production planning and logistics
  • intelligent simulation of virtual production lines
  • process optimisation in cloud manufacturing
  • smart predictive maintenance of machines
  • adaptive business processes in smart retail environments 
  • adaptive safe autonomous driving

Selected system prototypes were demonstrated at the CEBIT fair, the Hannover Industry fair, and the international Consumer Electronics Show (CES).

Since 2008, the research team is part of the DFKI Agents and Simulated Reality department (formerly: DFKI Deduction and Multiagent Systems department) and successfully contributed to many funded R&D projects in its core research areas.
