摘要
This paper presents the applicability of soft set theory for discovering attribute dependency in multi-valued information systems. The proposed approach is based on the notion of multi-soft sets. An inclusion of value sets in soft set theory is used to discover degree of attributes dependency. The results obtained are equivalent to the rough attributes dependency.
