2.4 Topic modelling Natural Language Processing (NLP) is an emerging field used by various researchers, and in NLP, topic modeling gained more attention in the field of text mining. It is a powerful technique used for text mining in data mining (Onan et al., 2016a). This technique is use...
Topic models are an unsupervised NLP method for summarizing text data through word groups. They assist in text classification and information retrieval tasks.

Topic modelling (TM) is a significant natural language processing (NLP) task and is becoming more popular, especially, in the context of literature synthesis and analysis. Despite the growing volume of studies on the use of and versatility of TM, the knowledge of TM development, especially from...
Each of the $$M$$ topics is represented by a vector of length $$V$$ that details which words are likely to occur, given a document on that topic. So for topic 1, 'learning', 'modelling' and 'statistics' might be some of the most common words. This means that you could then say...
