WebLSA uses SVD for the statistical analysis, whereas WordICA uses the ICA method. Moreover, LSA is often used to analyze and represent documents whereas WordICA is used to do the same for words. However, both the ICA and SVD analysis can be conducted to representations at the level of documents, paragraphs, sentences or individual words. Webanalysis (ICA) can overcome these restrictive assumptions and takes advantage of higher order statistics (beyond 2nd order).
