Novel signal representation of descriptors dependency in information retrieval based on wavelet spectral analysis
2013 ACS International Conference on Computer Systems and Applications (AICCSA)
The representation of texts in the current methods of information extraction, and TextMining in general, does not always reflect the dependencies between descriptors. In the vector representation, for example, descriptors related are often considered to be either totally independent or totally similar . This type of approach can be considered as a coarse resolution of the document. We propose in this paper a new method of information retrieval based on signal representation and spectraldoi:10.1109/aiccsa.2013.6616445 dblp:conf/aiccsa/HassaniM13 fatcat:vod4ttkbljftndx4esqllhfnya
