The objective of this research is to represent the managerial logic of Mr. Yung-Ching Wang, the Chairman of Formosa Plastics Group (also known as the “God of Business” in Taiwan) through the construction of knowledge maps using a text-mining approach, including automatic key phrase extraction, term identification, document vector modeling, and a clustering method named growing hierarchical self...

Many of today's organizations already have a strong integration of groupware systems in their ITinfrastructure. The shared databases of these groupware systems form organizational memories, which comprise the complete knowledge of an organization collected over the time of its existence. One key problem is how to find relevant knowledge or information in continuously growing and distributed org...

This paper presents a computational framework for information extraction and aggregation which aims to integrate and organize the data/information resources that spread throughout the Internet in the manner that makes them useful for tracking events such as natural disaster, and disease dispersion. We introduce a simple statistical information extraction technique for summarizing the document i...

If Topic Maps should be exchanged in distributed environments a common semantic problem occurs: Do two Topics refer to the same Subject? If they describe the same Subject the given Topics have to be treated as one unit in the given context. Especially in integration scenarios this might be important. Within the Topic Map theory the merging paradigm and the description of Subjects of discourse i...

Die ‘Document Suite’ ist eine Sammlung von Werkzeugen für die verschiedenen Aufgaben beim Erschließen der Inhalte von elektronisch verfügbaren Dokumenten aus dem WWW oder aus anderen Dokumentbeständen. Bei ihrer Konzeption und Realisierung wurde konsequent darauf gesetzt, die Vorteile von XML und die der zugehörigen Formalismen und Werkzeuge auszunutzen: alle Module der ‘Document Suite’ erwarte...

Recently, a parallel hash function based on chaotic maps with changeable parameters was proposed by Li et al (2011, pp.1305-1312). In this paper, the security of it is analyzed and the weakness of the architecture is pointed out. It is found that the main limitations are the error using of floor, round and exclusive OR operations in the algorithm. In order to counterstrike these, some improveme...

Interdisciplinary research and development projects in medical engineering bene t from well selected collaboration partners. The process of nding such partners from often unfamiliar elds is di cult, but can be supported by an expert pro le that is based on patent analysis and classifying the patents to competence elds in medical engineering. Patent analysis and categorization are di cult and re...

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...
