In summary, analyzing a social position from a GrC perspective has two major advantages. On the one hand, it extends the application scope of the GrC methodology. On the other hand, we can logically transform relational granulation of social networks into functional granulation; as a result, the well-developed techniques of data table analysis can be applied to social position analysis. Thus, this...
In this paper, we investigate the issues of positional definability of a concept in the framework of first-order logic. The positional definability of a concept means that the concept can be defined using social positions. While social positions can be induced from social relations via social network analysis, our results show that the definability of a concept using the underlying social relations,...
