Towards Verifying Semantic Roles Co-occurrence
This work addresses a foundational issue in natural language processing for linguists and AI researchers, but it appears incremental as it builds on existing semantic role theory.
The paper tackled the problem of unrestricted semantic role combinations in verb representations by arguing for hidden restrictions, using an evidence-based approach on the VerbNet database to demonstrate these constraints.
Semantic role theory considers roles as a small universal set of unanalyzed entities. It means that formally there are no restrictions on role combinations. We argue that the semantic roles co-occur in verb representations. It means that there are hidden restrictions on role combinations. To demonstrate that a practical and evidence-based approach has been built on in-depth analysis of the largest verb database VerbNet. The consequences of this approach are considered.
