Fig. 2. Signal and frequency decomposition
Fig. 3. Original text and knowledge structure model
Figure 4 shows a sample wavelet decomposition. It is a signature decomposition using a
Daubechies wavelet, a wavelet specially suited for this type of image. Figure 5 shows a
MLW decomposition of a generic text. There, C i , and C j,k stand for abstract knowledge and
F m represents filters. This Figure will be described further in the final section.
