ItemA novel document ranking method using the discrete cosine transformPark, LAF ; Palaniswami, M ; Ramamohanarao, K (IEEE COMPUTER SOC, 2005-01)We propose a new Spectral text retrieval method using the Discrete Cosine Transform (DCT). By taking advantage of the properties of the DCT and by employing the fast query and compression techniques found in vector space methods (VSM), we show that we can process queries as fast as VSM and achieve a much higher precision.
