Abstract
We have coped with several aspects related to Non-deterministic Information Systems (NISs), and we have proposed a mathematical framework 'Rough Non-deterministic Information Analysis' (RNIA). In rule generation, we employed possible equivalence classes, and showed the effective calculation by NIS-Apriori algorithm. In this paper, we focus on data dependencies in NISs, and reconsider the calculation by granules inf and sup.
