[Research paper] Hierarchical Topic Modelling Over Time
I am proud to present you HTMOT for Hierarchical Topic Modelling Over Time. This paper proposes a novel topic model able to extract topic hierarchies while also modelling their temporality. Modelling time provide more precise topics by separating lexically close but temporally distinct topics while modelling hierarchy provides a more detailed view of the content of a document corpus.
The code is easily accessible on GitHub and a working interface provides the ability to navigate through the resulting topic tree with ease: https://github.com/JudicaelPoumay/HTMOTsubmitted by /u/Addicted_to_math
