In this position paper we discuss the role of geographical metaphors as tools for representing, organizing and accessing heterogeneous shared information, typical of the Web 2.0. Metaphors represent concepts and relations of a knowledge domain with symbols taken from another domain, usually simpler and more immediate to understand. The paper discusses issues related to the use of metaphorical c...

In this paper we describe knowledge management in engineering. In the WISE project we have investigated the needs of engineers, involved in analysis and design processes in large innovative industries. We focus on the reuse of knowledge, on how knowledge can be found, understood, reused in a new context, and stored. A knowledge portal has been developed which gives a single access to all kinds ...

Information is available in many forms from different sources, in distributed locations; access to information is supported by networks of varying performance; the cost of accessing and transporting the information varies for both the source and the transport route. Users who vary in their preferences, background knowledge required to interpret the information and motivation for accessing it, g...

The aim was to disentangle the extent to which semantic memory problems in patients with AD are best characterized as loss of semantic knowledge rather than difficulties in accessing semantic knowledge. METHOD A longitudinal approach was applied. The s...
