Key research themes
1. How does usage frequency shape argument structure representation and acquisition?
This research theme investigates how usage-based factors such as frequency, contingency, and input variability influence the cognitive representation, learning, and generalization of argument structure constructions. The focus is on understanding argument realization not as a fixed lexical property but as emergent from language use, which matters for modeling acquisition and processing.
2. What is the nature of instrumental participants in argument structure and their syntactic-semantic status?
This theme addresses the debated status of instruments as event participants in verbal argument structure. It considers whether instruments behave as full arguments syntactically and semantically or occupy a gradient intermediate position, contributing to refining argument-adjunct distinctions that are central to understanding event representation and verb semantics.
3. How can argument structure constructions and their semantic integration be formally represented and computationally implemented?
This theme focuses on computational and formal linguistic approaches to modeling argument structure constructions, combining lexical and constructional semantics to encode predicate-argument relations. Addressing formal representations is essential for integrating linguistic theory with natural language processing (NLP) systems and understanding constructional variability across languages.
