In this paper, we consider using NLP to represent documents in a topic space using Latent Dirichlet Allocation and solving the information retrieval problem via finding document similarities in the topic space rather than doing it in the corpus vocabulary space. We also used the TF-IDF method in...
Topic models are an unsupervised NLP method for summarizing text data through word groups. They assist in text classification and information retrieval tasks.
in the documents, it uncovers these distributions which indicate important semantic relationships. Topic modeling has been widely studied in machine learning, text mining, and natural language processing (NLP). This chapter gives an introduction to topic modeling. It covers both the fundamental ...

Topic modeling is applied in different fields. Natural Language Processing (NLP) tasks have leveraged topic modeling, like text summarization and sentiment analysis. Moreover, the powerfulness of topic modeling is extended to other fields, like bioinformatics and economics. TM is also used with other...
Topic modeling is a natural language processing (NLP) technique for determining the topics in a document. Also, we can use it to discover patterns of words in a collection of documents. By analyzing the frequency of words and phrases in the documents, it’s able to determine the probability...
What are Topic Modeling toolkits? There are many toolkits available for the application of topic models. They are predominantly used in Natural Language Processing (NLP). Here are three popular topic modeling toolkits: Gensim Stanford topic modeling toolbox (TMT) ...
