Kno.e.sis Publications

The World Wide Web is fast becoming a ubiquitous computing environment. Prevalent keyword-based search techniques are scalable, but are incapable of accessing information based on concepts. We investigate the use of concepts from multiple, real-world pre-existing, domain ontologies to describe the underlying data content and support information access at a higher level of abstraction. It is not practical to have a single domain ontology to describe the vast amounts of data on the Web. In fact, we expect multiple ontologies to be used as different world views and present an approach to "browse" ontologies as a paradigm for information access. …

For an enterprise to take advantage of the opportunities afforded by electronic commerce it must be able to make decisions about business transactions in near-real-time. In the coming era of segment-of-one marketing, these decisions will be quite intricate, so that customer treatments can be highly personalized, reflecting customer preferences, the customer's history with the enterprise, and targeted business objectives. This paper describes a paradigm called “decision flows” for specifying a form of incremental decision-making that can combine diverse business factors in near-real-time.

This paper introduces and empirically analyzes a variety of optimization strategies for decision flows that are “data-intensive”, i.e. …

An Epistemological And Methodological Study Of Technology Foresight, Choon Lee Chai

Student Works (2000-2009)

This research is an epistemological and methodological study of technology foresight. The low realisation rate (28%) of technology foresight has put into question as to whether foresight research is a scientific research, and whether foresight method is a scientific method. ln this research, the notion of scientific method is critically analysed. A comparison between physical and social science research is also made in order to highlight their basic similarities and differences. The Delphi method, which is the fundamental method of technology foresight, is epistemologically evaluated, particularly with regards to its basic assumptions and premises. Apart from the above, the research …
