....Expectation Maximization (EM) Algorithm of Dempster et al. 15] to compute the authority weights of the pages. Their work is based on the Probabilistic Latent Semantic Analysis framework introduced by Hofmann [24] who proposed a probabilistic alternative to Singular Value Decomposition. Hofmann [25] proposes an algorithm similar to PHITS which also takes into account the text of the documents. These algorithms require specifying in advance the number of factors. Furthermore, it is possible that the EM Algorithm gets stuck in a local maximum, without converging to the true global maximum. ....
