Abstract
In many real world applications, data are organized by coverings, instead of partitions. Covering-based rough sets have been proposed to cope with this type of data. Covering-based rough set theory is more general than rough set theory, then there is a need to employ sophisticated theories to make it more adaptive to applications. Covering is one of core concepts in covering-based rough sets, and it is urgent to connect coverings with other data models. This paper establishes the relationship between coverings and bipartite graphs. Through its index set, a covering induces some isomorphic bipartite graphs. Conversely, a bipartite graph induces a covering of the set of vertices. These inductions are converse with each other.
