...eworks of collaborative filtering [11] and iterative diffusion algorithm [9], as well as some more complicated methods such as Probabilistic Latent Semantic Analysis [36], Latent Dirichlet Allocation [37] and Iterative Latent Semantic Analysis [38]. Systematic investigation on tag-aware recommendation algorithms must be very helpful in the futuredesign of recommender systems. 5. Acknowledgement We ack...

...Statistical topic modeling [Blei et al., 2003; Blei and Lafferty, 2009] also requires sufficient words in a document to infer the document topic distribution....

...Compared with traditional latent semantic analysis (LSA) [Deerwester et al., 1990] and topic modeling such as latent Dirichlet allocation (LDA) [Blei et al., 2003], explicit semantic analysis (ESA) has the advantage of providing semantics that are interpretable by human beings....

...Since this approach, uses statistical methods like latent semantic analysis (LSA) (Hofmann 1999) and latent Dirichlet allocation (LDA) (Blei et al. 2003), it is called statistical models too....

...• Topic model features: by making use of the Gensim topic modelling library [80], several LDA [81] and LSI [82] topic models with varying granularity (k = 20, 50, 100 and 200) were trained on data corresponding to each fine-grained category of a cyberbullying event (e.g. threats, defamations, insults, defenses)....
