Affective Event Classification with Discourse-enhanced Self-training (2020.emnlp-main)
Copied to clipboard
| Challenge: | Prior work on recognizing affective events focused on producing lexical resources of verbs or event phrases with corresponding affective polarity values. |
| Approach: | They propose a BERT-based model for affective event classification and a discourse-enhanced self-training method that iteratively improves the classifier with unlabeled data. |
| Outcome: | The proposed model outperforms existing models with unlabeled data and improves recall and precision. |

Minimally Supervised Learning of Affective Events Using Discourse Relations (D19-1)
Copied to clipboard
| Challenge: | Existing methods for learning affective events that trigger positive or negative sentiment are difficult because of the unbounded combinatorial nature of language. |
| Approach: | They propose to propagate affective polarity using discourse relations using a small seed lexicon and large raw corpus. |
| Outcome: | The proposed method learns affective events effectively without manually labeled data, and improves supervised learning when labeles are small. |
Human Needs Categorization of Affective Events Using Labeled and Unlabeled Data (N18-1)
Copied to clipboard
| Challenge: | Recent research has focused on identifying affective events in text, which are activities or states that positively or negatively affect the people who experience them. |
| Approach: | They propose to categorize affective events based upon human need categories that often explain people’s motivations and desires: PHYSIOLOGICAL, HEALTH, LEISURE, SOCIAL, FINANCIAL, COGNITION, and FREEDOM. |
| Outcome: | The proposed model learns from unlabeled data and produces significantly better results than individual classifiers. |

Domain-Specific Sentiment Lexicons Induced from Labeled Documents (2020.coling-main)
Copied to clipboard
| 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. |
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. |
