Figurative Usage Detection of Symptom Words to Improve Personal Health Mention Detection (P19-1)
Copied to clipboard
| Challenge: | Past work in personal health mention detection uses classification-based methods with human-engineered features or word embedding-based features. |
| Approach: | They propose to combine a pipeline-based and a feature augmentation-based approach to combine personal health mention detection with figurative usage detection to improve the accuracy of the prediction. |
| Outcome: | The proposed method improves the F-score of personal health mention detection by 2.21% over the pipeline-based approach and feature augmentation-based approaches. |
Recognising Agreement and Disagreement between Stances with Reason Comparing Networks (P19-1)
Copied to clipboard
| Challenge: | Existing methods for (dis)agreement detection focus on conversational settings . however, non-dialogic stance-bearing utterances are common in real-world scenarios . |
| Approach: | They propose a reason comparing network to leverage reason information for stance comparison. |
| Outcome: | The proposed method outperforms baselines on a well-known stance corpus. |
Cross-Target Stance Classification with Self-Attention Networks (P18-2)
Copied to clipboard
| Challenge: | In stance classification, the target on which the stance is made defines the boundary of the task, and a classifier is usually trained for prediction on the same target. |
| Approach: | They propose a neural model that can generalize classifiers between different targets by finding useful information shared between relevant targets. |
| Outcome: | The proposed model can generalize between relevant targets and find useful information shared between relevant target domains which improves generalization in certain scenarios. |
Assessing Social License to Operate from the Public Discourse on Social Media (2020.coling-industry)
Copied to clipboard
| Challenge: | Social License to Operate (SLO) is the level of support organisations gain from the public. |
| Approach: | They propose to extract and transform peoples’ stances towards an organisation into SLO levels by performing a chain of three text classification tasks. |
| Outcome: | The proposed system extracts and transforms peoples’ stances towards an organisation into SLO levels. |
