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.
我们提出了一种使用离散余弦变换（DCT）的新型光谱文本检索方法。通过利用DCT的特性，并采用向量空间方法（VSM）中发现的快速查询和压缩技术，我们证明我们可以像VSM一样快速处理查询，并实现更高的精度。
