Hybrid N-gram model using Naïve Bayes for classification of political sentiments on Twitter

TLDR
This study hybridize two n-gram models, unigram and n- gram, and applied Laplace smoothing to Naïve Bayesian classifier and Katz back-off on the model in order to smoothen and address the limitation of accuracy in terms of precision and recall of n- Gram models caused by the ‘zero count problem.’
Abstract
Twitter, an online micro-blogging and social networking service, provides registered users the ability to write in 140 characters anything they wish and hence providing them the opportunity to express their opinions and sentiments on events taking place. Politically sentimental tweets are top-trending tweets; whenever election is near, users tweet about their favorite candidates or political parties and at times give their reasons for that. In this study, we hybridize two n-gram [two n-gram models used in this study are unigram and n-gram. Therefore, in this study, where unigram is mentioned that refers to a least-order n-gram (unigram) and where n-gram is mentioned that refers to the highest-order (full sentence or tweet level) n-gram] models and applied Laplace smoothing to Naive Bayesian classifier and Katz back-off on the model. This was done in order to smoothen and address the limitation of accuracy in terms of precision and recall of n-gram models caused by the ‘zero count problem.’ Result from our baseline model shows an increase of 6.05% in average F-Harmonic accuracy in comparison with the n-gram model and 1.75% increase in comparison with the semantic-topic model proposed from a previous study on the same dataset, i.e., Obama–McCain dataset.

Co-attention networks based on aspect and context for aspect-level sentiment analysis

TL;DR: Zhang et al. as discussed by the authors proposed a co-attention mechanism to capture the interactions between aspect and context, which interactively concentrates the semantic influences on context and aspect to generate greater informative representation.
