Can You Be More Explicit? A Task and Dataset on Explicitations of Implicit Meaning

Summary

Researchers introduce a new task and dataset focused on "explicitations," which are text revisions making implicitly conveyed meaning explicit to enhance comprehension. Utilizing wikiHow revision histories, a rule-based method extracts candidate explicitations, which are then human-annotated to differentiate them from new information insertions. Analyses reveal the task is challenging and subjective, reflecting varying background knowledge. Experimentally, off-the-shelf Large Language Models achieve promising performance, though with inconsistent gains from few-shot prompting and fine-tuning. In contrast, fine-tuned Natural Language Inference models consistently benefit from supervised training and demonstrate stronger robustness under distribution shift. The annotated dataset provides valuable signals for future model development.

Key takeaway

For NLP engineers developing systems to enhance text comprehension by making implicit meaning explicit, you should recognize the inherent subjectivity and challenge of this task. While LLMs show promise, consider fine-tuned Natural Language Inference models for more consistent performance and stronger robustness, especially when facing distribution shifts. Your efforts can utilize the provided dataset for effective supervised training.

Key insights

Making implicitly conveyed meaning explicit significantly enhances text comprehension.

Principles

• Distinguishing explicitations from new information is challenging and subjective.
• Background knowledge and reasoning influence explicitation judgments.
• Supervised training consistently benefits NLI models for this task.

Method

A rule-based approach extracts candidate explicitations from wikiHow revision histories, followed by human annotation to distinguish them from new information.

In practice
