Seq2Emo: A Sequence to Multi-Label Emotion Classification Model (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing methods for multi-label emotion classification are based on binary relevance and classifier chain (CC) |
| Approach: | They propose a sequence-to-emotion approach which implicitly models emotion correlations in a bi-directional decoder. |
| Outcome: | The proposed approach outperforms state-of-the-art methods on a SemEval’18 and GoEmotions dataset. |
Automatic Dialogue Generation with Expressed Emotions (N18-2)
Copied to clipboard
| Challenge: | a growing interest in neural dialogue generation systems is focusing on generating human-like responses based on past utterances . despite efforts, few consider putting restrictions on the response itself . authors present three models that concatenate the desired emotion with the source input . |
| Approach: | They propose three models that concatenate the desired emotion with the source input or push the emotion in the decoder. |
| Outcome: | The proposed model is more efficient than the previous models, but it lacks the emotion vector. |
Neural Path Hunter: Reducing Hallucination in Dialogue Systems via Path Grounding (2021.emnlp-main)
Copied to clipboard
| Challenge: | Dialogue systems that generate factually incorrect responses are often unfitful and hallucinate factuality invalid. |
| Approach: | They propose a method to improve faithfulness and reduce hallucination of neural dialogue systems to known facts supplied by a Knowledge Graph. |
| Outcome: | The proposed approach improves faithfulness and reduces hallucination of dialogue systems to known facts . it leverages a token-level fact critic to identify plausible sources of hallucinism . |
Enhanced Entity Annotations for Multilingual Corpora (2022.lrec-1)
Copied to clipboard
| Challenge: | Named Entity Recognition (NER) is a new language for natural language processing. |
| Approach: | They propose to improve the annotation quality of the English Wikipedia tool WEXEA . they propose to use a proven NER system to annotate entities in Wikipedia . |
| Outcome: | The proposed tool can be used to exhaustively annotate entities in Wikipedia articles. |
