Recall & Precision

clausa query : 0.544, text query : 0.251

The experimental results showed that latent semantic indexing with clause query works better than text query with average precision is 0.5442 and 0.2509 for clause and text query respectively.

The proposed method of latent semantic indexing succeeds to exploit semantic value of automatic-annotation-based image retrieval.
