| Research Abstract |
This research project aimed at constructing foundations of efficient knowledge discovery from data of large scale and of various data types, stored in databases. We clarified various properties of the lattice structure consisting of various types of structured data, designed machine learning/knowledge discovery algorithms by using efficient search of lower sets in the lattices, and applied some of them to theoretical open problems or to problems in science other than informatics. We found that the property of lower sets as being closed sets is useful for both fundamental theories and applications.
