%X In this paper, we introduce the concept of Q-fuzzy left [right, twosided]ideal in semigroups. Moreover, the operations with Q-fuzzy setsand its related properties are discussed. Especially, we investigate therelationship between Q-fuzzy point and Q-fuzzy left [right] ideal. Finally,some theorems are given to characterize intra-regular semigroupsin terms of fuzzy semiprime Q-fuzzy [left, right] ideals.
