Title

Science and technology mapping : a new iteration model for representing multidimensional relationships

Abstract

Much effort has been done to develop more objective quantitative methods to analyze and integrate survey information for understanding research trends and research structures. Co-word analysis is one class of techniques that exploits the use of co-occurences of items in written information. However, there are some bottlenecks in using statistical methods to produce mappings of reduced information in a comfortable manner. On one hand, often used statistical software for PCs has restrictions for the amount for calculable data; on the other hand, the results of the mufltidimensional scaling routines are not quite satisfying. Therefore, this article introduces a new iteration model for the calculation of co-word maps that eases the problem. The iteration model is for positioning the words in the two-dimensional plane due to their connections to each other, and its consists of a quick and stabile algorithm that has been implemented with software for personal computers. A graphic module represents the data in well-known 'technology maps'
