For nouns with both gender forms, we aim at removing the gender inequality on the semantic gender direction as shown in Figure 1 and Figure 2.
we minimize the difference between the distance of feminine form of the word w f and the masculine form of the word w m to an anchor point (e.g., the origin point) on the semantic gender direciton d s : (3) Note that for most cases, w m and w f lie on the opposite sides of the anchor point on the semantic gender axis.
