Finding the right semantic distance to be used for information research, classification or text clustering using Natural Language Processing is a problem studied in several domains of computer science. We focus on measurements that are real distances: i.e. that satisfy all the properties of a distance. This paper presents one ISA-distance measurement that may be applied to taxonomies. This dist...

In this issue of Neuron, Wang et al. and Machold and Fishell present contrasting molecular fate maps of Math1, which redefine the derivatives of the embryonic rhombic lip and offer a conceptual overhaul of cerebellar and precerebellar development. These fate maps identify a common developmental thread linking diverse, functionally associated neurons and reveal an exquisite temporal organization...

In [6] Carlsson demonstrated that all the pertinent conceptual constructs of strategic management theory can be represented with a knowledge based support (KBS)-system with hyperknowledge properties. Furthermore, he shows that cognitive maps can be used to trace the impact of the support and to generalize the experiences of the users. In this paper we will show that the effectiveness and useful...

The typological literature generally assumes that semantic maps and the underlying conceptual spaces have mental reality, that is, they correspond to a universal arrangement of the relevant conceptual situations in a speaker's mind, based on perceived relations of similarity between these conceptual situations (Croft 2001 and 2003, Haspelmath 2003, among others). Croft (2003) goes far as arguin...

Generally, National Mapping Agencies (NMAs) produce and maintain topographic and cadastral maps. Regular update of map products is the most critical problem faced by NMAs. Therefore, implementation of new technology to automate map generalization has become crucial in updating smaller-scale maps from frequently updated larger-scale maps. Additionally, customized data products can be produced. I...

The paper aims to discuss strengths and weaknesses of using Object Role Modeling (ORM) and UML Class Diagrams for conceptual modeling of Topic Maps. Established evaluation criteria for conceptual modeling languages are used to compare Topic Map ontology modeling with ORM and UML, to try to find if ORM is a good alternative to UML. The paper discusses a few extensions to simplify viewing ORM dia...
