July 1, 2004... ABSTRACT Systems analysis and design are vital steps in information systems development. One of the key constructs in modeling information systems during systems analysis and design is the relationship construct (Siau et al., 1995, 1996,...

An exploration of a set of entropy-based hybrid splitting methods for decision tree induction.(Class-Attribute Mutual Information family )
July 1, 2004... ABSTRACT Decision tree (DT) induction is among the more popular of the data mining techniques. An important component of DT induction algorithms is the splitting method, with the most commonly used method being based on the Conditional...

XTOPO: An XML-based topology for information highway on the Internet.(Extensible Markup Language)
July 1, 2004... The need for interoperation and data exchange through the Internet makes XML a dominant standard language. Much work has been done on translating relational data into XML documents and vice versa. However, there is not an integrated method to...

Scalable QSF-trees: retrieving regional objects in high-dimensional spaces.
July 1, 2004... Many database applications require effective representation of regional objects in high-dimensional spaces. By applying an original query transformation, a recently proposed access method for regional data, called the simple QSF-tree...

An efficient concurrency control algorithm for high-dimensional index structures.
July 1, 2004... In this paper, we propose a concurrency control algorithm based on link-technique for high-dimensional index structures. In high dimensional index structures, search operations are generally more frequent than insert or delete operations and...
