    A Smart Shopping Assistant utilising Adaptive Plan Recognition
    (11. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2003) Schneider, Michael
    In this paper we describe an adaptive shopping assistant system utilising plan recognition. Radio Frequency Identification (RFID) sensory is used to observe a shopper’s actions, from which the plan recogniser tries to infer the goals of the user. Using this information, an automated assistant provides help tailored to the shopper’s concrete needs. We discuss why it is crucial to make the plan recognition process itself user adaptive and present ideas how to realise this through modification of existing plan recognition approaches.

    Adaptive Reading Assistance for Dyslexic Students: Closing the Loop
    (15th Workshop on Adaptivity and User Modeling in Interactive Systems, 2007) Schmidt, Andreas; Schneider, Michael
    Adaptive reading assistance can improve the reading performance of students, but current dyslexia pedagogical theories do not yet provide sound results on a micro-level. We want to provide a reading assistance solution that both helps the learner and the dyslexia researcher. In order to archive this, we encode adaptation knowledge in a descriptive way by making use of state-of-the-art ontology-based techniques. This enables a closed-loop approach of continuous improvement. In this paper, we want to present the overall approach as well as initial results of our work within the EU project AGENT-DYSL.

    A Context Map as the Basis for a Microservice Architecture for the Connected Car Domain
    (INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft, 2019) Abeck, Sebastian; Schneider, Michael; Quirmbach, Jan-Philip; Klarl, Heiko; Urbaczek, Christof; Zogaj, Shkodran
    In the near future cars will have two properties: They will be electrically powered and they will be connected to the Internet. Such cars will provide a huge amount of sensor data which can be accessed via web APIs in order to develop innovative connected car applications, such as traffic control, hazard warning, assisted or even autonomous driving. However, current software solutions in this field are mainly monoliths solving single problems in an isolated way. Therefore, we propose a systematic approach by which each single connected car application becomes part of a microservice architecture. This approach requires a sound and well-elaborated domain model from which the microservices' APIs and implementation of the applications can be systematically derived. The main contribution of this paper is a context map for the connected car domain. We demonstrate a structured software development approach with the example of a mobile application, the Electric Car Charger, by showing how this application is integrated into the context map and, thus, into a connected car microservice architecture.

    Extended lattice reduction experiments using the BKZ algorithm
    (Sicherheit 2010. Sicherheit, Schutz und Zuverlässigkeit, 2010) Schneider, Michael; Buchmann, Johannes
    We present experimental results using lattice reduction algorithms. We choose the BKZ algorithm, that is the algorithm considered the strongest one in this area in practice. It is an important task to analyze the practical behaviour of lattice reduction algorithms, as the theoretical predictions are far from being practical. Our work helps choosing the right parameters for lattice reduction in practice. The experiments in this paper go beyond the results of Gama and Nguyen in their Eurocrypt 2008 paper. We give evidence of some facts stated in their work, concerning the runtime and the output quality of lattice reduction algorithms.
