Both Topic Maps and RDF are popular semantic web standards designed for machine processing of web documents. Since these representations were originally created for different purposes, they have conceptual differences in their data models, and therefore have different tools to parse, store, and query them. However, there are more tools to handle RDF data than those existing for Topic Maps. Our ...

We describe a new, simple conceptual model for tables. The conceptual model treats a table as a map that has a domain which is a product of categories or index sets and a codomain which is a set of entry values. We demonstrate how we can use the model to specify the semantics of some tabular editing operations.

Background and our research goal Background ■Ontology: It is important that the ontology captures the essential conceptual structure of the target world as generally as possible. ■Domain experts often want to understand the target world from the domain-specific viewpoints in which they are interested. In many cases their interests are different, even if they are experts in the same domain. Onto...

Use a Map-ematical Framework for GIS Modeling — describes a conceptual structure for map analysis operations and GIS modeling Getting the Numbers Right — describes an alternative framework based on how the map values are retrieved to classify analytical operations. Options Seem Endless When Reclassifying Maps — discusses the basic reclassifying map operations Overlay Operations Feature a Variet...

Argumentation maps are visual representations of argumentation structures, making it possible to efficiently examine the cumulative results of protracted, distributed, and complex argumentation processes. Such visualizations can be useful to, for example, informally assess the status of public debates. Although the elicitation of argumentation maps is well supported, the support for the (1) ana...

This paper compares and contrasts the way knowledge is captured and manipulated between COPE and conceptual graphs. COPE, an acronym for Cognitive Policy Evaluation, is existing computer software whereas a conceptual graphs processor is a potential such candidate. COPE depicts the cognitive maps of Eden (1991), whose work stems from that of Kelly (1955). Conceptual graphs are another form of co...

Conventional methods of map comparison frequently produce unhelpful results for a variety of reasons. In particular, conventional methods usually analyze pixels at a single default scale and frequently insist that each pixel belongs to exactly one category. The purpose of this paper is to offer improved methods so that scientists can obtain more helpful results by performing multiple resolution...

This paper presents a comprehensive, corpus-based study of adjectival concepts. An adjectival concept is a semantic class of adjectives, for example, “adjectives which express feeling”. We represent adjectival concepts by abstract nouns (such as “feeling”), and extract instances where abstract nouns are modified by adjectives (such as “happy feeling”) from a large corpus of Japanese newspaper a...
