Enhancing General Sentiment Lexicons for Domain-Specific Use (C18-1)
Copied to clipboard
| Challenge: | Lexicon based methods for sentiment analysis rely on high quality polarity lexicons. |
| Approach: | They evaluate SentProp framework for inducing domain-specific polarities from word embeddings and use it to enhance a general-purpose lexicon for use in the political domain. |
| Outcome: | The proposed framework performs worse than the original lexicon in an out-domain task, showing that the words added and the polarity shifts applied are domain-specific and do not translate well to an out domain setting. |
Is “hot pizza” Positive or Negative? Mining Target-aware Sentiment Lexicons (2021.eacl-main)
Copied to clipboard
| Challenge: | Existing sentiment lexicons assume words’ sentiments are invariant within a domain, but this assumption is weak for fine-granularity analyses of text sentiments. |
| Approach: | They propose a "perturb-and-see" method to extract commonsense sentiments from large-scale datasets by binding a word's sentiment to its collocation words instead of domain labels. |
| Outcome: | The proposed framework is able to achieve highly competitive performances on the unsupervised opinion relation extraction task. |
