In this paper the equivalence ${\tilde{𝒬}}^{U}$ on a semigroup $S$ in terms of a set $U$ of idempotents in $S$ is defined. A semigroup $S$ is called a $𝒰$ -liberal semigroup with $U$ as the set of projections and denoted by $S (U)$ if every ${\tilde{𝒬}}^{U}$ -class in it contains an element in $U$ . A class of $𝒰$ -liberal semigroups is characterized and some special cases are considered.
