Ontology mapping is the key to data interoperability in the semantic web. This problem has received a lot of research attention, however, the research emphasis has been mostly devoted to automating the mapping process, even though the creation of mappings often involve the user. As industry interest in semantic web technologies grows and the number of widely adopted semantic web applications in...

An integrated representation of large-scale space, or cognitive map, called PLAN is presented that attempts to address a broader spectrum of issues than has previously been attempted in a single model. Rather than examining wayfinding as a process separate from the rest of cognition, one of the fundamental goals of this work is to examine how the wayfinding process is integrated into general co...

Fostering conceptual and cognitive change in learners can be difficult. Students often come to a learning situation with robust, implicit understandings of the material under study. One explanation for the implicit nature of these understandings is a lack of metaknowledge about the knowledge to be acquired. Helping learners create metaknowledge may free paths to conceptual change. This paper pr...

Mental mapping of spaces, and of the possible paths for navigating these spaces, is essential for the development of efficient Orientation and Mobility (O&M) skills. Most of the information required for this mental mapping is gathered through the visual channel. People who are blind lack this information, and in consequence they are required to use compensatory sensorial channels and alternativ...

In this chapter, the main idea about a design tool and its object database system will be described. The design tool should improve design practice with respect to analysis and improving existing and planned urban environments. Preconditions for defining the design tool’s purpose are the determination of the “well-situated” urban elements, their impact on cognitive mapping, and the exploitation...

The semantic web envisions the Internet as a globally linked database, one that supports data interoperability and machine readable semantics. The “back-bone” of the semantic web is structural representations of domains of knowledge in the form of ontologies. A critical prerequisite to supporting this global information exchange is that mappings must exist between domain related ontologies. The...

The ability to maintain cognitive function during aging is a complex process subject to genetic and environmental influences. Alzheimer's disease (AD) is the most common disorder causing cognitive decline among the elderly. Among those with AD, there is broad variation in the relationship between AD neuropathology and clinical manifestations of dementia. Differences in expression of genes invol...

Eye movements provide a rich and informative window into a personÕs thoughts and intentions. In recent years researchers have increasingly employed eye movements to study cognition in psychological experiments, to understand behavior in user interfaces, and even to control computers through eye-based input devices. Unfortunately, like speech and handwriting, eye movements generate vast amounts ...

This chapter introduces portfolio system design perspectives that incorporate concept mapping and the map-based user interface. It also presents a prototype of a portfolio system that has been developed based on the discussed perspectives, along with its capacities and the lessons learned in the design and pilot-testing processes. The author argues that a concept map-based design can enhance a ...
