- 4 abstract "The study follows action science approach to the problem of nonprofit housing services. After 4 months of action science-based activities, such as organized participant observations, in-depth interviews, field work, and focus group studies, the main findings are (1) Web 2.0 suits nonprofit organizations better than traditional webs in terms of maintenance cost and usability, (2) mapping tools make better GUI with respect to web-based housing services, and (3) context-aware personalization can translate to better user experiences as an RDFS-based working prototype has been built and tested. A user survey shows high level user satisfaction. Although the case study was carried in a nonprofit housing organization, the practices in action research approach can be applied to other NPOs as well.".

- 420 abstract "The term "Web 2.0" is used to describe applications that distinguish themselves from previous generations of software by a number of principles. Existing work shows that Web 2.0 applications can be successfully exploited for technologyenhance learning. However, in-depth analyses of the relationship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare. In this article, we will analyze the technological principles of the Web 2.0 and describe their pedagogical implications on learning. We will furthermore show that Web 2.0 is not only well suited for learning but also for research on learning: the wealth of services that is available and their openness regarding API and data allow to assemble prototypes of technology-supported learning applications in amazingly small amount of time. These prototypes can be used to evaluate research hypotheses quickly. We will present two example prototypes and discuss the lessons we learned from building and using these prototypes.".

- 424 label "Structured Objects in OWL: Representation and Reasoning".
- 424 sameAs 424.
- 424 abstract "Applications of semantic technologies often require the representation of and reasoning with structured objects---objects composed of many parts connected in complex ways. Although OWL is a general language, its class descriptions and axioms cannot be used to describe arbitrarily connected structures. OWL ontologies of structured objects can thus be underconstrained, which reduces the inferences that can be drawn and causes performance problems in reasoning. Therefore, we extend OWL with description graphs, which allow modelers to describe structured objects in a simple and more precise way. To represent conditional aspects of the domain, we also allow for SWRL-like rules over description graphs. Based on a novel observation about the nature of many structured objects, we ensure decidability of our formalism. We also present a hypertableau-based decision procedure, which we implemented in the HermiT reasoner. We extracted description graphs from the well-known biomedical ontologies GALEN and FMA, classified them successfully, and even detected a modeling error in GALEN.".
