| Challenge: | a wordnet-based sentiment lexicon can be built to express sentiment polarity in a way shared across domains. |
| Approach: | They propose a method to build a sense-level sentiment lexicon on the basis of a wordnet . they use a rich set of wordnet-based features to recognize and assign sentiment polarity values . |
| Outcome: | The proposed method allows for the construction of a more reliable sentiment lexicon . the proposed method is partially automated, but it's performance drops in cross-domain applications . |

| Challenge: | Existing sentiment lexicons and concept-based sentiment-tagged corpora are not accurate, and it is difficult to map sentiment scores accurately to different languages. |
| Approach: | They examine existing sentiment lexicons and sense-based sentiment-tagged corpora to find out how sense and concept-based semantic relations effect sentiment scores. |
| Outcome: | The proposed lexicon can be used to generate sentiment lexicos for English using the Open Multilingual Wordnet. |
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. |

| Challenge: | Existing studies on sentiment lexicons have focused on domain-dependent sentiment words. |
| Approach: | They propose a graph-based technique to detect and correct domain-dependent sentiment words . they propose to use a sentiment lexicon to classify sentiments in a lexical-based classifier . |
| Outcome: | The proposed method is effective on multiple datasets from different domains. |
Enhancing a Lexicon of Polarity Shifters through the Supervised Classification of Shifting Directions (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing polarity shifter lexica only specify when a word can cause shifting, but do not specify when this is limited to a single shifting direction. |
| Approach: | They propose a classifier that determines the shifting direction of polarity shifters by using resource-driven features and data-driven feature. |
| Outcome: | The proposed classifier enhances the largest available polarity shifter lexicon. |
Attentive Gated Lexicon Reader with Contrastive Contextual Co-Attention for Sentiment Classification (D18-1)
Copied to clipboard
| Challenge: | Existing sentiment lexicons do not handle word sense and the concept of semantic compositionality is non-existent in simple lexiconic approaches. |
| Approach: | They propose a lexicon-driven contextual attention mechanism and a contrastive co-attention mechanism that models contrasting polarities between all positive and negative words in a sentence. |
| Outcome: | The proposed model outperforms many other neural baselines on sentiment classification tasks on multiple benchmark datasets. |

| Challenge: | Existing sentiment lexicons reflect abstract notion of polarity and do not do justice to substantial differences of word polarities between domains. |
| Approach: | They propose to use domain-specific sentiment lexicons to induce initial word intensity scores and train new deep models based on word vector representations to overcome the scarcity of the seed data. |
| Outcome: | The proposed models show that they perform well on review classification and cross-lingual word sentiment prediction. |
