  title={Laplacian Co-hashing of Terms and Documents},
  author={Dell Zhang and Jun Wang and Deng Cai and Jinsong Lu},
A promising way to accelerate similarity search is semantic hashing which designs compact binary codes for a large number of documents so that semantically similar documents are mapped to similar codes within a short Hamming distance. In this paper, we introduce the novel problem of co-hashing where both documents and terms are hashed simultaneously according to their semantic similarities. Furthermore, we propose a novel algorithm Laplacian Co-Hashing (LCH) to solve this problem which directly… CONTINUE READING
