Semantic Span Annotation: An Exploratory Study of LLM Annotation (2026.acl-srw)
Copied to clipboard
| Challenge: | Structured span extraction research is siloed by context length, annotation task, and domain . Identifying a span within a natural language text and affixing it with a semantic label has been considered a core task in NLP . |
| Approach: | They propose a framework for structured span annotation that integrates five datasets under a common JSONL format with character-level offsets. |
| Outcome: | The proposed framework can generalize across four domains under three prompting configurations. |

| Challenge: | Recent studies have explored alternative vector representations with different inductive biases or capabilities. |
| Approach: | They propose a Python library that extends probabilistic box embeddings to geometric shapes and regions. |
| Outcome: | The proposed library is fully open source and compatible with PyTorch and TensorFlow. |
