However, previous works generally view the abstract as plain text, ignoring the fact that it is a description of a certain entity and can be decomposed into different topics. ...
Then, we predict the topic distribution of each abstract sentence, and decode the sentence from topic-aware representations with a Pointer-Generator network. ...
Inspired by this work, Perez-Beltrachini et al. (2019) uses a convolutional encoder and a hierarchical decoder, and utilizes the Latent Dirichlet Allocation model (LDA) to render the decoder topic-aware ...

In this paper, we present two new partially supervised generative models of labeled text, Partially Labeled Dirichlet Allocation (PLDA) and the Partially Labeled Dirichlet Process (PLDP). ...
These models make use of the unsupervised learning machinery of topic models to discover the hidden topics within each label, as well as unlabeled, corpus-wide latent topics. ...
Popular unsupervised approaches like Latent Dirichlet Allocation [5] , Latent Semantic Indexing [11] and related methods [20, 3] are well suited for exploratory text analysis-e.g. ...
