a locality-sensitive sketch built from random hyperplane rounding, so the bits of two items agree in proportion to their cosine similarity.

In information retrieval, SimHash refers to a locality-sensitive sketch built from random hyperplane rounding, so the bits of two items agree in proportion to their cosine similarity. This meaning comes from Charikar (2002) in Proceedings of the thiry-fourth annual ACM symposium on Theory of computing.[1]
