Topic Modeling: A Comprehensive Review
Abstract. Topic modelling is the new revolution in text mining. It is a statistical technique for revealing the underlying semantic structure in large collection of documents. After analysing approximately 300 research articles on topic modeling, a comprehensive survey on topic modelling has been presented in this paper.
An Overview of Topic Representation and Topic Modelling Methods for
Topic Modelling is a popular method to extract hidden semantic knowledge present in the collection of documents. Due to increase in textual data, topic models play significant role to infer meaningful topics in texts. In this paper, we present a survey of various topic representations and topic models used to discover topics in long and short texts. Topic modelling methods are grouped into ...

Building the Bridge: Topic Modeling for Comparative Research
ABSTRACT. In communication research, topic modeling is primarily used for discovering systematic patterns in monolingual text corpora. To advance the usage, we provide an overview of recently presented strategies to extract topics from multilingual text collections for the purpose of comparative research. Moreover, we discuss, demonstrate, and ...
Topic Modeling in Management Research: Rendering New Theory from
Increasingly, management researchers are using topic modeling, a new method borrowed from computer science, to reveal phenomenon-based constructs and grounded conceptual relationships in textual data. By conceptualizing topic modeling as the process of rendering constructs and conceptual relationships from textual data, we demonstrate how this new method can advance management scholarship ...
Title: Topic Modelling Meets Deep Neural Networks: A Survey
A comprehensive overview of neural topic models, a research area that combines topic modelling and deep neural networks for text analysis. Learn about the models, applications, challenges and future directions of this fast-growing field.
Topic Modelling in Python with NLTK and Gensim
Research paper topic modelling is an unsupervised machine learning method that helps us discover hidden semantic structures in a paper, that allows us to learn topic representations of papers in a corpus. The model can be applied to any kinds of labels on documents, such as tags on posts on the website. The Process. We pick the number of topics ...
A Study of Topic Modeling Methods
Topic model provides an easy means to analyze huge amount of untagged text as well as other data. A topic can be defined as a group of words that happen to occur together at a greater frequency. Topic models connects words that have similar kind of meanings and differentiate among words with different or multiple meanings. So, topic models in simple words are a set of algorithms that unveil ...
PDF Latent Dirichlet Allocation
Latent Dirichlet allocation (LDA) is a generative probabilistic model of a corpus. The basic idea is that documents are represented as random mixtures over latent topics, where each topic is charac- terized by a distribution over words.1. LDA assumes the following generative process for each document w in a corpusD: 1.

Using AgentM to watch for new research papers of interest
I'm getting enough of the pieces of AgentM in place that I'm able to get it to do useful things. I wrote a small program (ok AgentM wrote part of it) that fetches the last days worth of research papers from arxiv.org, filters them to the papers related to topics I care about, and then projects those filtered papers to a uniform markdown format for easy scanning: It uses gpt-4o-mini so it ...
Study: Transparency is often lacking in datasets used to train large
The Data Provenance Explorer could help AI practitioners build more effective models by enabling them to select training datasets that fit their model's intended purpose. In the long run, this could improve the accuracy of AI models in real-world situations, such as those used to evaluate loan applications or respond to customer queries.

The definition, characterization and implementation of Positive Energy Districts is crucial in the path towards urban decarbonization and energy transition. However, several issues still must be addressed: the need for a clear and comprehensive definition, and the settlement of a consistent design approach for Positive Energy Districts. As emerged throughout the workshop held during the fourth ...
