Association plots—a visualization technique for the independence problem in 2-way contingency tables—are extended in three directions: 1. The visualization is enhanced by using colors for the importance of the residuals. 2. The implementation currently available in R is improved using a more modular design and allowing a more flexible specification of plotting parameters. 3. Two methods for the...

Databases and networks currently have different service models. Database services are data-centric in that users typically describe the content of data and the system finds and returns matching data. However, traditional Internet services are server-centric in that users have to know the location of data (e.g., a URL) in order to retrieve it. We envision a future in which Internet services are ...

a r t i c l e i n f o The Ratio of Equivalent Transparency (Req) is a basic index for assessing whether a building is energy-efficient in Taiwan. Req is the ratio of the area of total building envelope and the area of envelope equivalent transparency. Calculation of Req requires not simply the consideration of natural factors such as building location, direction, ambient lighting and sunshine, ...

This paper investigates the role of multi-modal metaphors for e-commerce applications. More specifically, the use of textual representations (including tabular representations and tables), graphical representations (including dynamically formed graphs) in the presence and absence of speech are investigated. The paper describes the initial study performed prior to the development of an experimen...
