“…They categorized detection algorithms into five types, including clustering, frequent pattern mining, exemplar-based technique, matrix factorization, and probabilistic models. Among these different kinds of algorithms, both probabilistic models and matrix factorization attract the most attention [7,12,14,16,24,25,29].…”

“…Likewise, Suri and Roy compared the use of LDA and NMF in topic detection in tweet collections and found that LDA takes longer to run. Therefore, in real-time scenarios, NMF is preferred for Twitter topic detection [25].…”

“…This approach is basically very useful for search engines, to automate the customer service and other areas where knowing the topics from texts is crucial. There are several algorithms available that be trained for topic modelling such as LDA, LSA, NMF and Clustering [34][35][36][37][38][39][40][41][42][43][44]. These algorithms are unsupervised methods, which means, the relationship among document is not revealed prior to the model being executed.…”
