HCM-L: Domain Specific Modeling for Active and Assisted Living

Modeling and modeling methods are crucial for information systems engineering but are seldom seamlessly integrated into all phases of development and operation: Practitioners challenge the benefits of modeling and complain about the confusing variety of concepts with overlapping semantics, symbols and syntactic rules of today’s standardized, “universal” modeling languages. Therefore, domain-specific modeling languages (DSMLs) are gaining increasing popularity: they are lean and convenient, support the productivity of modeling, and help to increase model quality and comprehensibility. There are, however, few approaches to embedding a DSML into a domain-specific modeling method (DSMM) that provides guidelines about how to use a given DSML and to evaluate related models. This chapter aims to make a contribution towards filling that gap by discussing, as an example and proof of concept, a domain-specific modeling method for the human cognitive modeling language HCM-L, a DSML for the domain of active and assisted living. As a modeling language without tool support has no chance to be used in practice, we are conducting that discussion on the basis of HCM-L modeler, a tool that was implemented using the metamodeling platform ADOxx and can be accessed via OMiLAB, the Open Models Laboratory for modeling method engineering. HCM-L modeler is component of an ambient assistance system for supporting elder persons in mastering their daily life activities.

Computergestütztes Mobiles Lernen

Die Informations- und Wissensgesellschaft setzt ein kontinuierliches und lebenslanges Lernen ihrer Mitglieder voraus. Dies gilt insbesondere fur die im Arbeitsprozess stehenden Berufstatigen, und zwar auf allen Ebenen. Dementsprechend wachst der Bedarf an Angeboten und Werkzeugen fur ein zeit- und ortsunabhangiges und damit kostengunstiges „Lernen nach Bedarf“. Klarerweise spielt hier die Mobilitat eine wichtige Rolle, da erst durch sie die Moglichkeit des ubiquitaren Lernens eroffnet wird. Die vorliegende Arbeit behandelt Rahmenbedingungen des Computer-gestutzten Mobilen Lernens, nennt ein dafur geeignetes Lernparadigma, zeigt die Anforderungen an die Lernenden sowie die Mobilisierbarkeit von typischen Lernprozessen auf und betrachtet aktuelle Technologien in diesem Bereich.

Model Centered Architecture

This paper advocates a rigorous model focused paradigm of information system development and use. We introduce the concept of “Model Centered Architecture” that sees an information system to be a compound of various networked models, each of which is formed with the means of a Domain Specific Modeling Language. This languages are tailored to the particular circumstances of the respective system aspect. I.e., from a MOF perspective, MCA focuses on the MOF levels M2 (definitions of the DSMLs to be used for the specification of the system and it’s contexts), M1 (Specification of all System and Data Components using the DSMLs) and M0 (the instances, i.e. models of concrete objects, functions and processes). The transformation of M0 citizens to the respective implementation concepts (Structure → Data, Function→ Program, Process→ Workflow) is delegated to mapping functions defined on M2, restricted on M1 to the particular schemata (in the sense of mappings between the respective sets of schema instances), and instantiated on M0 for the concrete instances. The paper shows how such model centered approach may be applied in practice using two real development projects as running examples.

Knowledge-Oriented Approach to Requirements Engineering in Ambient-Assisted Living Domain

This paper sketches HBMS(Human Behavior Monitoring and Support), an Ambient Assisted Living (AAL) approach deriving cognitive behavioral models from individual behavioral processes and using this knowledge “learned” to compensate individual memory gaps. In the context of HBMS individual behavioral processes represent the requirements to customize an individual assistive system.

Technology has changed the way we live, think and work. Technology has revolutionized business and now it must revolutionize teaching and learning. Live classroom based training is becoming too costly and cumbersome. 80 % of teachers and students already use computers. So e-learning can be seen as a means supporting life long learning with a lot of benefits. The worldwide web, high-capacity networks and high speed computers make learning available to people 24 hours a day in their office, at home or also in hotel rooms during a business trip around the globe. E-learning enables the access to learning when it is convenient.
