Adaptive Local Context and Syntactic Feature Modeling for Aspect-Based Sentiment Analysis

open access: yesApplied Sciences, 2023
Aspect-based sentiment analysis is a fine-grained sentiment analysis task that consists of two types of subtasks: aspect term extraction and aspect sentiment classification. In the aspect term extraction task, current methods suffer from the lack of fine-

Learning Sentiment-Specific Word Embedding for Twitter Sentiment Classification [PDF]

open access: yesProceedings of the 52nd Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers), 2014
We present a method that learns word embedding for Twitter sentiment classification in this paper. Most existing algorithms for learning continuous word representations typically only model the syntactic context of words but ignore the sentiment of text. This is problematic for sentiment analysis as they usually map words with similar syntactic context

Automatically extracting polarity-bearing topics for cross-domain sentiment classification [PDF]

open access: yes, 2011
Joint sentiment-topic (JST) model was previously proposed to detect sentiment and topic simultaneously from text. The only supervision required by JST model learning is domain-independent polarity word priors.
