Exclusive Topic Modeling

no code implementations6 Feb 2021 Hao Lei, Ying Chen

We propose an Exclusive Topic Modeling (ETM) for unsupervised text classification, which is able to 1) identify the field-specific keywords though less frequently appeared and 2) deliver well-structured topics with exclusive words.
