Researchers have published many articles in the field of topic modeling and applied in various fields such as software engineering, political science, medical and linguistic science, etc. There are various methods for topic modeling, which Latent Dirichlet allocation (LDA) is one of the most ...
We can imagine that LDA will place documents in the space according to the document topics. For example, in our case with topics computer science, physics, and biology, LDA will put documents into a triangle where corners are the topics. We can see this in the image below where each ...
In February last year, there was avideo cliponline that Daeil Kim, a data scientist at New York Times, spoke at NYC Data Science Meetup. Honestly, I still have not watched it yet (but I think I should have.) What his work is also about computational journalism, on his algorithm, and...

A computational model for online topic evolution mining was established through a latent semantic analysis process on textual data.Topical evolutionary analysis was achieved by tracking the topic trends in different time-slices.In this paper,Latent Dirichlet Allocation(LDA)was extended to the context of...
