Abstract. This paper proposes a mechanism for 3-way feature interactions occurrence and a system for detecting 3-way interactions based on the proposed mechanism. In this paper, by analyzing examples, the mechanism of 3-way interactions is clarified and a detection algorithm of 3-way interactions is proposed. The problem of terminal assignments for the detection of 3-way interactions is also discussed. To validate the algorithm, we applied the proposed algorithm to 120 combinations out of 12 services, and 82 3-way interactions were detected in the 42 combinations.
