Topic Map Generation Using Text Mining

Starting from text corpus analysis with linguistic and statistical analysis algorithms, an infrastructure for text mining is described which uses collocation analysis as a central tool. This text mining method may be applied to different domains as well as languages. Some examples taken form large reference databases motivate the applicability to knowledge management using declarative standards of information structuring and description. The ISO/IEC Topic Map standard is introduced as a candidate for rich metadata description of information resources and it is shown how text mining can be used for automatic topic map generation

Organizing learning materials through hierarchical topic maps: an illustration through Chinese herb medication

[[abstract]]This research aims to use hierarchical topic maps to compile digital learning material and to discuss its design and application possibilities. The system renders tremendous original assets and then embeds a self-organizing map (SOM) in the material database to produce topical learning materials, as in this case, an illustration through Chinese herb medication. It helps to demonstrate robust professional information as well as knowledge structures, and provides a customized and interactive learning dynamic to support both progressive and constructive learning styles. The paper first gives a detailed procedural description of the material construction, explains how topic map techniques were applied, and observes the implications and potentials of the technology to education. Both the technical and educational evaluations of using SOM topic maps in compilation of learning materials have resulted in positive feedback. SOM allows users to review the complete databank in structural hierarchical order, which provides comprehensive understanding of the entire set of learning materials, and also brings opportunities to users to discover knowledge related to their study area.[[notice]]補正完

Effective Progression of Temporary Virtual Teams Over Time: a Pragmatic Investigation towards the Development of an Internal Structure to Support Knowledge Sharing

Enabled by communications and information technology, temporary virtual teams are able to utilize talent from anywhere in the globe to service customers, solve business problems, and provide unique educational experiences. Temporary virtual teams, however, face many challenges to their effectiveness. In particular, many challenges to effective communication and knowledge sharing exist. To be effective, methods intended to address the unique challenges presented in the temporary virtual team environment are needed. This paper presents practical methodologies that can be used towards the development of an internal structure to support knowledge sharing between temporary virtual teams

Research Enterprise Office Search Portal

All the employees in University Technology Petronas need to access information instantaneously in order to enhance their functionality and efficacy. Is it easy to collaborate and gather the right information at the right time? Is all the research within a company documented? Is it easily available to all employees? And what happens when an employee leaves the company? This project is an analysis of current practices and outcomes of the search portal and the nature of it as they are evolving in most of the organizations. The findings suggest that interest in search engines across a variety of industries is very high, the technological foundations are varied, and the major concerns revolve around achieving the correct amount and type of accurate research and garnering support for contributing to the search portal. Implications for practice and suggestions for future research are drawn from the study findings. This project focused on the search function. The research is on how to make this search portal useful to the University Technology Petronas (UTP) community that is the UTP staff and lecturers. These search portal solutions are ideal for operations and maintenance manuals that once were reserved for 3-inch thick binders sitting on the shelves of many treatment plants. Moving the manual standard procedures, troubleshooting, theory, alarms, and equipment descriptions to an electronic, web-based solution offers many benefits. For one, the information can be updated and kept current much more effectively because it can be changed in one place and instantly updated at all access points. By developing this search portal, the staff and lecturers will be able to get information fast and efficiently

A new framework for a technological perspective of knowledge management

Rapid change is a defining characteristic of our modern society. This has huge impact on society, governments, and businesses. Businesses are forced to fundamentally transform themselves to survive in a challenging economy. Transformation implies change in the way business is conducted, in the way people perform their contribution to the organisation, and in the way the organisation perceives and manages its vital assets – which increasingly are built around the key assets of intellectual capital and knowledge. The latest management tool and realisation of how to respond to the challenges of the economy in the new millennium, is the idea of "knowledge management" (KM). In this study we have focused on synthesising the many confusing points of view about the subject area, such as: a. different focus points or perspectives; b. different definitions and positioning of the subject; as well as c. a bewildering number of definitions of what knowledge is and what KM entails. There exists a too blurred distinction in popular-magazine-like sources about this area between subjects and concepts such as: knowledge versus information versus data; the difference between information management and knowledge management; tools available to tackle the issues in this field of study and practice; and the role technology plays versus the huge hype from some journalists and within the vendor community. Today there appears to be a lack of a coherent set of frameworks to abstract, comprehend, and explain this subject area; let alone to build successful systems and technologies with which to apply KM. The study is comprised of two major parts: 1. In the first part the study investigates the concepts, elements, drivers, and challenges related to KM. A set of models for comprehending these issues and notions is contributed as we considered intellectual capital, organizational learning, communities of practice, and best practices. 2. The second part focuses on the technology perspective of KM. Although KM is primarily concerned with non-technical issues this study concentrates on the technical issues and challenges. A new technology framework for KM is proposed to position and relate the different KM technologies as well as the two key applications of KM, namely knowledge portals and knowledge discovery (including text mining). It is concluded that KM and related concepts and notions need to be understood firmly as well as effectively positioned and employed to support the modern business organisation in its quest to survive and grow. The main thesis is that KM technology is a necessary but insufficient prerequisite and a key enabler for successful KM in a rapidly changing business environment.Thesis (PhD (Computer Science))--University of Pretoria, 2010.Computer Scienceunrestricte

COMPUTER-SUPPORTED COLLABORATIVE KNOWLEDGE BUILDING IN ENGINEERING DESIGN

Engineering design is defined as a process of devising a technical system, component, or process to satisfy desired needs. Collaborative engineering design (CED) is a knowledge- intensive process that involves multidisciplinary people working jointly, sharing resources and outcomes, and building new knowledge while solving problems. People need to collaborate synchronously or asynchronously, either in the same place or distributed geographically. This thesis proposes that engineering design can be modeled not only as a process of knowledge transformation, but as a process of collaborative knowledge building (CKB). CKB is a goal-driven collaborative process of generating and refining ideas and concepts of value to the community. Properly applied and supported, CKB has the potential to improve both learning and design outcomes resulting from collaborative design projects. Existing collaboration tools have evolved without a clear understanding of designers’ needs, even though a portion of the required functionalities has been achieved separately. This thesis proposes an integrated CKB-orientated model for collaborative engineering design, incorporating the key elements of Stahl’s CKB model, Lu’s ECN-based collaborative engineering model, Nonaka’s knowledge creation theory, and Sim and Duffy’s model of a design activity. Based on the model, a set of specific requirements for collaboration tools are presented and some functionalities not existing currently are identified
