The remark most often made about knowledge capitalization is that the tools and approaches used take a long time to implement. Today, time is of the essence and products have to be designed rapidly with simple, less determinist tools that are not only more communicative and operational but also favor collective rather than individual learning. For a number of years we have focused on designing ...

The ability to understand and process multiple mental contexts is an important aspect of human cognition. By “mental contexts” we mean different beliefs, states of knowledge, points of view, or suppositions, all of which may change over time. In this paper, we propose an approach for modeling and reasoning about the interactions among multiple mental contexts using the context activation scheme...

The ability to evidence learning effectiveness in virtual learning environments for accreditation purposes has posed as a challenge to higher education institutions who offer online courses. Many instructional designers have tried several methods for retrieving learning object, resulting in varying levels of object quality. For institutions who offer online courses and who are initially applyin...

In this paper, we provide a principled and unified explanation how knowledge in global 3-D structural invariants, typically captured by a group action on a symmetric structure, can significantly facilitate the task of reconstructing a 3-D scene from one or more images. More importantly, the “absolute” pose between the camera frame and the canonical frame that a symmetric structure admits can he...

The use of Knowledge Organization Systems (KOS) as ontologies or terminologies for the description of scholarly contents requires a careful consideration of the domain and the KOS available. KOS in the same domain may differ in several dimensions including purpose, level of formality, structure and language. In consequence, curators of scientific data face the problem of selecting the relevant ...

In this paper, graphical, conceptual graph-based representations for knowledge structures in the compositional development method DESIRE for knowledge-based and multi-agent systems are presented, together with a graphical editor based on the Constraint Graph environment. Moreover, a translator is described which translates these graphical representations to textual representations in DESIRE. Th...

This paper considers the emerging phenomenon of crowdsourced cartography in relation to ideas about the organisation of contemporary knowledge production in capitalist societies. Taking a philosophical perspective that views mapping as a processual, creative, productive act, constructed through citational, embodied, and contextual experiences, we examine how we might profi tably analyse collabo...

Based on 4158 articles from 9 financial journals during 2009-2013 from Web of Science, we use CiteSpace III to construct the knowledge mapping of finance studies. As a result, the primary research power distribution is shown. Further, finance research hotspots and major research fields are revealed via keywords co-occurrence analysis and references co-citation analysis. The findings show that t...

To better understand the topic of this colloquium, we have created a series of databases related to knowledge domains [dynamic systems (small world/Milgram), information visualization (Tufte), co-citation (Small), bibliographic coupling (Kessler), and scientometrics (Scientometrics)]. I have used a software package called HistCite which generates chronological maps of subject (topical) collecti...
