Conflicts widely exist in social problems. In order to better straight forwardly present and semantically describe conflict analysis problem, and inspired by three-way approximate concept analysis on the incomplete contexts, this paper regards a conflict table as a three-valued formal context. And based on the context, generalized three-way operators and their inverse operators are proposed, through which object-induced generalized three-way concept (GOE-concept) can be obtained. Moreover, the relevant properties of GOE-concepts are presented to state that the set of all the GOE-concepts can form the GOE-concept lattice. Then, the visual description of conflict analysis problem based on GOE-concept is discussed explaining that the intent of each GOE-concept is a description of common characters under the agent contained in the extent. Finally, the relationships between the object-induced three-way approximate concept lattice (OE-approximate concept lattice) and GOE-concept lattice are discussed, which further illustrates that the GOE-concept can describe the common information of conflict analysis more comprehensively and richly than the OE-approximation concept.

Key words: conflict analysis, three-valued formal context, description of common characters, object-induced three-way approximate (OE-approximate) concept lattice, object-induced generalized three-way concept (GOE-concept) lattice
