We discuss the design and the implementation of a flexible and scalable fuzzy case-based matching engine. The engine’s flexible design is illustrated for two of its core components: the internal representation of cases by means of a variety of crisp and fuzzy data types, and the fuzzy operations to execute the ensuing case matching process. We investigate the scalability of the matching engine ...

Music plays an important, and sometimes overlooked part in the transformation of communication and distribution channels. With a global market volume exceeding $ 40 billion, music is not only one of the primary entertainment goods in its own right. Since music is easily personalised and transmitted, it also permeates many other services across cultural borders, anticipating social and economic ...

This paper analyzes the fundamental changes in market structures that may result from the increasing use of information teChnology. First, an analytic framework is presented and its usefulness is demonstrated in explaining several major historical changes in American business structures. Then, the framework is used to help explain how electronic markets and electronic hierarchies will allow clo...

introduction: the purpose of this in vitro study was to compare the coronal seal of four temporary filling materials, coltosol, zonalin, zamherir, and intermediate restorative material (irm) by the india ink dye penetration test. materials and methods: endodontic access preparations were prepared in 120 extracted intact human premolars. the teeth were randomly divided into six groups including ...

This paper studies the impact of hurricanes on housing markets and population turnover using microdata from Florida during 2000–2016. We find that cause a temporary increase in home prices concurrent decrease transactions, which together imply negative transitory shock to supply. Using mortgage application data, we incoming homeowners this period have higher incomes, leading an overall shift to...

The Iowa Electronic Markets are small, real-money financial markets designed to aggregate information about future events. The market microstructure of these markets is studied and a market making model is developed to provide liquidity for one set of securities offered by this exchange. A computer program was created to employ the market making model and profit from the market’s inefficiencies...

This paper takes a critical look at electronic markets. Through an examination of Hong Kong's air cargo industry, where an electronic network recently has begun its operation, we argue that none of the key industry stakeholders stand to gain from an electronic market. Instead we found that the existing electronic network has limited its service to carefully preserve the distribution of power am...

Evidence has shown that the provision of product information in electronic markets decreases the price elasticity of demand due to the ‘fit’ cost. This effect, however, could differ according to how consumers perceive the value of the product information to their quality evaluation procedures. If the information has very limited value, then they may not rely on it; thus, the demand elasticity m...

This paper presents our experiences in using an approach to teaching and learning that incorporates elements from games. In particular we describe a simulation game that has been used in a graduate course on Agent Technology for E-commerce to teach students principles of electronic markets and strategic interaction.
