| Research Abstract |
In this study, we categorized various types of existing methods for relational data and proposed new methods for analysis of the data and evaluation of the results. As a main result, new methods for multidimensional scaling, clustering algorithm and network analysis have been proposed to deal with the large and complex data. More precisely, the large and complex data are regarded as symbolic data, which consists of multi-valued data, interval-valued data and distribution-valued data, and several methods that reduce the loss of information have been proposed based on the notion of symbolic data.
