The TM4L environment enables the development and use of ontology-aware courseware based on the Semantic Web technology Topic Maps. In this paper we discuss its features in the light of authoring support, giving illustrative examples to highlight its use.

This paper presents an approach to routing telephone calls automatically, based upon their speech content. Our data consist of a set of calls collected from a customer-service center with a twolevel menu, which allows jumping past the second level, and we view the routing of these calls as a topic-identification problem. Our topic identifier employs a multinomial model for keyword occurrences. ...

This paper presents a framework of context-centered digital course libraries founded on the Topic Maps paradigm and used for developing an authoring environment for building such libraries. We explore the idea of using contexts to support more efficient information search. The notion of context is perceived as abstraction of grouping of domain concepts and resources based on the existing semant...

We propose the first routing engine for computing driving directions in large-scale road networks that satisfies all requirements of a real-world production system. It supports arbitrary metrics (cost functions) and turn costs, enables real-time queries, and can incorporate a new metric in less than a second, which is fast enough to support real-time traffic updates and personalized cost functi...

This paper studies the security of a recently proposed chaos-based cryptosystem. It is shown that the encryption architecture of this cryptosystem possesses some important problems related to its implementation and its robustness against noise. Some security problems are also highlighted.

Digital folklore collections are valuable sources for studying the cultural and oral tradition of a country. The main difficulty in managing such collections is material heterogeneity (handwritten texts, photographs, 3D objects, sound recordings etc.) that imposes different digitization, description and maintenance practices. A multi-layer metadata model for the description of a digital folklor...

In this short note we discuss totally transitive maps. We show that all chaotic maps are not necessarily totally transitive, but there are chaotic maps with this property. Our discussion relates to symbol space Σ2 and real line.

Interviewing stakeholders is a common way to elicit information about requirements of the system-to-be and the conditions in its operating environment. One difficulty in preparing and doing interviews is how to avoid missing the information that may be important to understand the requirements and environment conditions. Some information may remain implicit throughout the interview, if the inter...

Having a glance at the historical sites such as Bing Ma Yung, Great Wall, Forbidden City, watching movies of history about China, flipping pages of stories about ancient China, China was once the most powerful nations. Nevertheless, industrial revolutions in 18 -19 century countries miles away improve the skills of industries, making the Great Britain as the most affluence countries at that tim...
