Abstract

Recently, Fourier and cosine discrete transformations have been proposed for textual document retrieval and ranking. The advantage of those methods is that they use spatial information about flow of terms through documents. Here, we investigate the question if consideration of important document elements like titles, sections, sentences, etc. improves efficiency the original Fourier domain scoring method.
