Social Network and One-sided Fuzzy Concept Lattices

In this paper we present information about our experiment with a social network of students from one school class. Each pupil has characterized his/her relationships to all schoolmates by value from the given range. Then we use onesided fuzzy concept lattice, a special method of relational data analysis, and especially modified Rice-Siff´s algorithm to form clusters. In the end we try to interpret the results as interesting groups of students which are viewed by their schoolmates in a similar way.
