Toward the enhancement of the getRNIA system for rough-set based data analysis

The getRNIA is a software tool for the rough-set based framework RNIA (Rough Non-deterministic Information Analysis), which can handle tables with uncertain data, especially non-deterministic data. This paper considers new functionalities in the getRNIA system for enhancing its ability. The first is the parallelization of the NIS-Apriori algorithm, and the second is the introduction of a new descriptor with disjunctive values, which we name Or-descriptor. The final is the estimation of the actual values in tables with uncertain data.
