Event Representation through Semantic Roles: Evaluation of Coverage

TL;DR

This paper evaluates the coverage of semantic role theory in event representation, highlighting its limitations and proposing a hybrid role-scalar approach based on empirical analysis.

Contribution

It provides empirical evidence of the insufficiency of pure semantic role theory and introduces a hybrid approach for better event representation.

Findings

Semantic role theory is necessary but not sufficient for complete event representation.

Empirical analysis supports the need for a hybrid role-scalar approach.

Preliminary results suggest improved coverage with the proposed method.

Abstract

Semantic role theory is a widely used approach for event representation. Yet, there are multiple indications that semantic role paradigm is necessary but not sufficient to cover all elements of event structure. We conducted an analysis of semantic role representation for events to provide an empirical evidence of insufficiency. The consequence of that is a hybrid role-scalar approach. The results are considered as preliminary in investigation of semantic roles coverage for event representation.
