Lexical Ambiguity in Political Rhetoric: Why Morality Doesn't Fit in a Bag of Words
British Journal of Political Science, 2023 How do politicians use moral appeals in their rhetoric? Previous research suggests that morality plays an important role in elite communication and that the endorsement of specific values varies systematically across the ideological spectrum.

A Novel Evolving Sentimental Bag-of-Words Approach for Feature Extraction to Detect Misinformation
International Journal of Advanced Computer Science and Applications, 2022 —The state-of-the-art misinformation detection techniques mainly focus on static datasets. However, a massive amount of information is generated online and the websites are flooded with this legitimate information and misinformation.

VisualSparta: An Embarrassingly Simple Approach to Large-scale Text-to-Image Search with Weighted Bag-of-words [PDF]
Annual Meeting of the Association for Computational Linguistics, 2021 Text-to-image retrieval is an essential task in cross-modal information retrieval, i.e., retrieving relevant images from a large and unlabelled dataset given textual queries. In this paper, we propose VisualSparta, a novel (Visual-text Sparse Transformer

A Comparative Study for Arabic Text Classification Based on BOW and Mixed Words Representations [PDF]
IJCI International Journal of Computers and Information, 2016 This paper compares two methods for features representation in Arabic text classification. These methods are bag of words (BOW) that mean the word-level unigram and mixed words representations.

Balinese Mask Characters Classification using Bag of Visual Words Model
Journal of Electrical, Electronics and Informatics, 2021 Mask, often known by Balinese as “Tapel”, is made of pule wood. It depicts the representation of characters in the “badbad” or legend. Bali has many types of mask dances that are often performed, which makes tourists interested in visiting Bali ...

The Influence of Order on a Large Bag of Words [PDF]
2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008 Text classification has been mostly performed through implicit semantic correlation techniques, such as latent semantic analysis. This approach however, has proved insufficient for situations where there are short texts to be classified into one or more from many classes.

What Is Not in the Bag of Words for Why-QA? [PDF]
Computational Linguistics, 2010 While developing an approach to why-QA, we extended a passage retrieval system that uses off-the-shelf retrieval technology with a re-ranking step incorporating structural information. We get significantly higher scores in terms of MRR@150 (from 0.25 to 0.34) and success@10.

Paraphrase Generation with Latent Bag of Words
CoRR, 2020 Paraphrase generation is a longstanding important problem in natural language processing. In addition, recent progress in deep generative models has shown promising results on discrete latent variables for text generation. Inspired by variational autoencoders with discrete latent structures, in this work, we propose a latent bag of words (BOW) model ...

Learning to Organize a Bag of Words into Sentences with Neural Networks: An Empirical Study
North American Chapter of the Association for Computational Linguistics, 2021 Sequential information, a.k.a., orders, is assumed to be essential for processing a sequence with recurrent neural network or convolutional neural network based encoders. However, is it possible to encode natural languages without orders?
