trained statistical model that exposes abstract topics in the collection. Each document may concern multi- ple topics in different proportions, like a news article.
Apr 7, 2012 Right now, humanists often have to take topic modeling on faith. But it's a long step up from those posts to the computer-science articles that explain the frequency of the topic as it varies over the print run
5 • Output: A set of k topics, each of which is represented by: 1. A descriptor, based on the top-ranked terms for the topic. Sample Titles from News Articles. For a human being it’s not a challenge to figure out which topic a news article belongs to. But how can we teach a computer to understand the same topics?

Topic modeling is not the only method that does this– cluster analysis, latent semantic analysis, and other techniques have also been used to identify clustering within texts. A lot can be learned from these approaches. Refer to this article for an interesting discussion of cluster analysis for text.
Comparing the number of articles for each day and the outbreak development, we noted that mass media news reports in China lagged behind the development of COVID-19. 2019-07-15 · 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.
into relevant topics such as digital innovation, digital business models, and factors theoretical articles, reviews and use case studies that are related to the use of this includes, for example, disinformation, fake news, hate speech, rumors,
Topic modeling can be easily compared to clustering. As in the case of clustering, the number of topics, like the number of clusters, is a hyperparameter. By doing topic modeling we build clusters of words rather than clusters of texts. A text is thus a mixture of all the topics, each having a certain weight. and, as we are talking about news article, the list of topics should be expanding in real time if something new happens and new articles talk about it. For simplicity's sake, let's assume all the articles are in the same language. 2016-09-20 · In topic modeling, the term “space of documents” has been transformed into “topic” space, and the “topic” space is smaller than word space.

Topic modeling can be easily compared to clustering. As in the case of clustering, the number of topics, like the number of clusters, is a hyperparameter. By doing topic modeling we build clusters of words rather than clusters of texts. A text is thus a mixture of all the topics, each having a certain weight.
To extract the topics of articles, I first had to transform each article into a word vector. I did this using tf-idf, short for “term frequency-inverse document frequency.” Topic modeling is a machine learning technique that automatically analyzes text data to determine cluster words for a set of documents.

Topic models can connect words with similar meanings and distinguish between uses of words with multiple meanings. For this analysis, I downloaded 22 recent articles from business and technology sections at New York Times. Articles published by News24 were sourced to conduct the analysis and answer the research questions set forth. The articles were cleaned and topic models were built to identify 20 latent topics. The articles are classified with their topic before a pairwise cosine similarity comparison is applied on topic corpora to identify similar topics between election periods. 2020-10-11 Topic Modeling of New York Times Articles.
