No full textIssues and Requirements for Bayesian Approaches in Context Aware Systems
No full textResearch in advanced context-aware systems has clearly shown
a need to capture the inherent uncertainty in the physical world, especially
in human behavior. Modelling approaches that employ the concept
of probability, especially in combination with Bayesian methods,
are promising candidates to solve the pending problems. This paper analyzes
the requirements for such models in order to enable user-friendly,
adaptive and especially scalable operation of context-aware systems. It
is conjectured that a successful system may not only use Bayesian techniques
to infer probabilities from known probability tables but learn, i.e.
estimate the probabilities in these tables by observing user behavior
Designing engaging interactions for exploration and sharing of multidisciplinary outcomes in environmental education
No full textThe recent advent of mash-ups based on geobrowsers and social networking technologies holds great potential to use maps for sharing outcomes of activities in Environmental Education and to raise awareness around environmental sustainability issues. However, in this paper we argue that further interaction design research for online community applications in the context of Environmental Education is required in two ways. Firstly, this project is investigating how exploration, contribution and sharing of environmental outcomes can be seamlessly embedded in the existing practice of Environmental Education to engage students in environmental activities. For this purpose, it is investigating various facets of ubiquitous computing, namely web-based interfaces, mobile technology use and tangible media installations. Secondly, this project analyses challenges to the dominant map and planet metaphors as virtual copies of the real world and explores design and metaphor alternatives which integrate outcomes of multidisciplinary, environmental initiatives that may not necessarily be location-specific. In line with the strong participatory strategy of Environmental Education itself, this practice-led design research uses a participatory design methodology and includes students, educators, organisers, and mentors of environmental activities in an initial user needs analysis, the design process and evaluation of prototypes
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
