Abstract: Formal concept analysis is an effective tool in data analysis and knowledge discovery, and it has been applied in various fields. Formal decision context is one of the key relational datasets in formal concept analysis and rule acquisition based knowledge discovery is its main research topic. In this paper, Wille's concept lattice and object-oriented concept lattice are used to study rule acquisition in formal decision context, the corresponding rule acquisition algorithm is explored, and employment data from universities is employed to illustrate the feasibility of the proposed algorithm.

Key words: formal decision context, knowledge discovery, concept lattice, rule acquisition, analysis of employment data
