The use of significance tests in science has been debated from the invention of these tests until the present time. Apart from theoretical critiques on their appropriateness for evaluating scientific hypotheses, significance tests also receive criticism for inviting misinterpretations. We presented six common misinterpretations to psychologists who work in(More)
Structured Abstract Purpose – Designing a model and tools that are (a) capable of representing and handling personal knowledge in different degrees of structuredness and formalisation and (b) usable and extensible by end-users. Design/methodology/approach – This paper presents the result of analysing literature and various data-models and formalism used to(More)
DeepaMehta is an open source semantic desktop application based on the topic maps standard. It's conceptualisation and especially the innovative graph-based user interface have been guided by findings in cognitive psychology in order to provide a cognitively adequate working environment for knowledge workers of all kind. DeepaMehta aims to evolve nowadays'(More)
In an attempt to create a lean vocabulary for incremental recording and step-wise formalisation of personal knowledge, we identified a set of common knowledge structures. These Conceptual Data Structures (CDS) were found to be inherent to a variety of different knowledge artefacts ranging from vague paper notes to highly structured documents. CDS is(More)
We present iMapping, a zooming based approach for visually organizing information objects. It was developed on top of semantic desktop technologies and especially targets the support of personal knowledge management. iMapping has been designed to combine the advantages of spatial hypertext and other proven visual mapping approaches like mind-mapping and(More)
QuiKey is an interaction approach that offers interactive fine grained access to structured information sources in a light weight user interface. It is designed to be highly interaction efficient for searching, browsing and authoring semantic knowledge bases as well as incremen-tally constructing complex queries. Empirical evaluation using a comparative(More)
iMapping is a visual technique for structuring information objects. It is based on research in the fields of visual mapping techniques , Information Visualisation and cognitive psychology. iMapping uses a Zooming User Interface to facilitate navigation and to help users maintain an overview in the knowledge space. An iMap is comparable to a large whiteboard(More)
