Redundancy-aware topic modeling for patient record notes. [PDF]

open access: yesPLoS ONE, 2014
The clinical notes in a given patient record contain much redundancy, in large part due to clinicians' documentation habit of copying from previous notes in the record and pasting into a new note.

Supervised Topic Models

open access: yes, 2010
We introduce supervised latent Dirichlet allocation (sLDA), a statistical model of labelled documents. The model accommodates a variety of response types. We derive an approximate maximum-likelihood procedure for parameter estimation, which relies on variational methods to handle intractable posterior expectations.

Topic Modelling Games [PDF]

open access: yes, 2020
This paper presents a new topic modelling framework inspired by game theoretic principles. It is formulated as a normal form game in which words are represented as players and topics as strategies that the players select. The strategies of each player are modelled with a probability distribution guided by a utility function that the players try to ...

ConTopic: Human-in-the-loop neural topic modeling with constraint loss for topic quality improvement

open access: yesVisual Informatics
Existing neural topic models often produce semantically ambiguous or low-quality topics, limiting their effectiveness in real-world applications. To address this, we propose ConTopic, a human-in-the-loop framework that integrates user-defined “must-link”

Automatic Seed Word Selection for Topic Modeling

open access: yesIEEE Access
Topic modeling is widely used to uncover latent semantic topics from a corpus. However, topic models often struggle to identify minor topics due to their tendency to prioritize dominant patterns in the data. They are also hindered by polysemous words and

Topic Modeling in Marathi

open access: yesCoRR
While topic modeling in English has become a prevalent and well-explored area, venturing into topic modeling for Indic languages remains relatively rare. The limited availability of resources, diverse linguistic structures, and unique challenges posed by Indic languages contribute to the scarcity of research and applications in this domain. Despite the
