| Research Abstract |
We coped with rough set theory and rough sets-based data mining. We have theoretically extended rough sets-based concepts in a standard table to concepts in a table with non-deterministic information. Especially in rule generation from a table, we have proposed NIS-Apriori algorithm, which can handle tables with non-deterministic information and the computational complexity is almost the same as the original Apriori algorithm. Furthermore, NIS-Apriori is sound and complete for rules defined in a table with non-deterministic information. We have practically implemented software in C and Prolog, and opened the execution logs in the web page. Currently, we are touching a prototype of a web version with NIS-Apriori.
