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) ...
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 Modeling is a method from the world of Natural Language Processing (NLP). With the help of unsupervised machine learning, text documents are statistically analyzed for word patterns in order to compile words into groups (the so-called "topics"): ...
Results as shown in Fig.6, evidence that data mining, topic model, statistics, semantics, latent Dirichlet allocation, information retrieval, natural language processing, neural topic model, word2vec, structural topic modeling, recurrent neural network, speech recognition, scientometrics, public policy,...
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...

3.1 Topic Modeling Analysis Topic modeling is a powerful technique within natural language processing (NLP) used to identify and extract hidden topics from extensive collections of text documents. We applied Latent Dirichlet Allocation (LDA) to uncover the underlying themes within the Twitter discussions...
