1. Partially positive in attitude etc.
   • Jason seemed to have two completely different ways of belonging and gaining significance — a negative method with his mother and a semipositive method with his father.1997, Kevin J. O'Connor, Lisa Mages Braverman, Lisa D. Braverman, Play Therapy Theory and Practice, →ISBN
2. Having a dual that is nonnegative.
   • The purpose of this short note is to give a remark on the decomposition theorem for direct images of canonical sheaves tensorized with Nakano semipositive vector bundles.2015, Taro Fujisawa, “A remark on the decomposition theorem for direct images of canonical sheaves tensorized with semipositive vector bundles”, in arXiv
3. Having all elements nonnegative where at least one is positive.
4. (materials engineering) A type of compression mold for plastics that allows for excess powder and flash, as in an open flash mold, but which allows for lower melt viscosities as in a fully positive mold.
   • For such products, a semipositive mold is designed (Fig. 1.1.14), with the flash at a right angle to the direction of pressure.1981, László Sors, László Bardócz, István Radnóti, Plastic molds and dies, →ISBN, page 26
