Recurrent Embedded Topic Model

open access: yesApplied Sciences, 2023
In this paper we propose the Recurrent Embedded Topic Model (RETM) which is a modification of the Embedded Topic Modelling (ETM) by reusing the Continuous Bag of Words (CBOW) that the model had implemented and applying it to a recurrent neural network ...

Automatic topic detection strategy for information retrieval in spoken document [PDF]

open access: yes, 2009
This paper suggests an alternative solution for the task of spoken document retrieval (SDR). The proposed system runs retrieval on multi-level transcriptions (word and phone) produced by word and phone recognizers respectively, and their outputs are ...

topicmodels: An R Package for Fitting Topic Models [PDF]

open access: yesJournal of Statistical Software, 2011
Topic models allow the probabilistic modeling of term frequency occurrences in documents. The fitted model can be used to estimate the similarity between documents as well as between a set of specified keywords using an additional layer of latent ...

Topic Models with Topic Ordering Regularities for Topic Segmentation [PDF]

open access: yes2014 IEEE International Conference on Data Mining, 2014
Documents from the same domain usually discuss similar topics in a similar order. In this paper we present new ordering-based topic models that use generalised Mallows models to capture this regularity to constrain topic assignments. Specifically, these new models assume that there is a canonical topic ordering shared amongst documents from the same ...

Visualizing Topic Models

open access: yesProceedings of the International AAAI Conference on Web and Social Media, 2021
Managing large collections of documents is an important problem for many areas of science, industry, and culture. Probabilistic topic modeling offers a promising solution. Topic modeling is an unsupervised machine learning method that learns the underlying themes in a large collection of otherwise unorganized documents.

Micro-blog topic detection algorithm based on topic model

open access: yes网络与信息安全学报, 2016
Micro-blog data has the characteristic of real-time,volume,short-text,and noise-rich.So it is a challenge for the traditional topic detection technology.A novel micro-blog topic detection algorithm based on topic model was proposed.Firstly,the micro-blog
