| Challenge: | Traditionally, SRL annotations focus on verbal predicates, but other types of predicate are frequent in natural language. |
| Approach: | They propose a semantic scheme for capturing predicate-argument relations for nominalizations, termed QANom, using crowdsourcing and QA-driven annotations. |
| Outcome: | The proposed scheme outperforms existing annotations and is useful for downstream tasks. |

| Challenge: | a portable system for weakly-supervised aspect-based sentiment extraction is presented . ABSApp is a weakly supervised aspect based sentiment analysis system . |
| Approach: | They present a portable system for weakly-supervised aspect-based sentiment extraction . ABSApp generates domain-specific aspect and opinion lexicons based on unlabeled dataset . |
| Outcome: | The proposed system is interpretable and user friendly and can be quickly and cost-effectively used across domains . it generates domain-specific aspect and opinion lexicons, edits them, and generates an aspect-based sentiment report . the system has been successfully used in movie review analysis and convention impact analysis . |
Finding the SWEET Spot: Analysis and Improvement of Adaptive Inference in Low Resource Settings (2023.acl-long)
Copied to clipboard
| Challenge: | Pre-trained Transformer-based language models such as BERT, DeBERTa, and GPT3 have become the go-to tool in NLP. |
| Approach: | They propose an Early-Exit fine-tuning method that assigns each classifier its own set of unique model weights, not updated by other classifiers. |
| Outcome: | The proposed method outperforms Early-Exit and Multi-Model at fast speeds while maintaining comparable scores to Early- Exit at slow speeds. |

| Challenge: | SetExpander is a corpus-based system for expanding a seed set of terms into a more complete set of words belonging to the same semantic class. |
| Approach: | They propose a corpus-based system for expanding a seed set of terms into a more complete set of words that belong to the same semantic class. |
| Outcome: | The proposed system can expand a seed set of terms into a more complete set of words belonging to the same semantic class. |

| Challenge: | Question-answer driven Semantic Role Labeling (QA-SRL) is an open and natural flavour of SRL, potentially attainable from laymen. |
| Approach: | They propose a question-answer driven semantic role labeling approach that uses question-announced questions to label predicate-argument relationships. |
| Outcome: | The proposed method yields high-quality annotation with dramatically higher coverage, enabling future replicable research of natural semantic annotations. |
SetExpander: End-to-end Term Set Expansion Based on Multi-Context Term Embeddings (C18-2)

| Challenge: | SetExpander is a corpus-based system for expanding a seed set of terms into a more complete set of words belonging to the same semantic class. |
| Approach: | They propose to use a corpus-based system for expanding a seed set of terms into a more complete set of words that belong to the same semantic class. |
| Outcome: | The proposed system can expand a seed set of terms, validate it, re-expand the expanded set and store it, thus simplifying the extraction of domain-specific fine-grained semantic classes. |
