| Outline of Final Research Achievements |
The goal of this research is to develop methods for knowledge discovery that uses both orders for attribute values and closed sets of from mixed data. Since knowledge discovery by closed set is one kind of technique called bi-clustering of binary relational data, we obtained a method for bi-clustering for matrix factorization and search of matrices. Also we analyzed relationship between closed sets obtained by various bi-clustering method. Moreover, we developed methods for principal component analysis of the tree structure using the partial order of the substructure of tree data, the thesaurus expansion using the order relation of the vocabulary in the natural language thesaurus, and discovery methods of the similarity of the tree structure data with the integer programming.
