Daniyar Itegulov, Ekaterina Lebedeva
TL;DR
This paper proposes a novel framework using dependent types and neo-Davidsonian events to effectively handle verb phrase anaphora in natural language understanding.
Contribution
It introduces an extended Dependent Type Semantics with a new atomic event type and an @-operator for improved anaphora resolution.
Findings
Framework successfully models verb phrase anaphora
Extended DTS captures shared event properties
Illustrative examples demonstrate effectiveness
Abstract
This paper studies how dependent typed events can be used to treat verb phrase anaphora. We introduce a framework that extends Dependent Type Semantics (DTS) with a new atomic type for neo-Davidsonian events and an extended @-operator that can return new events that share properties of events referenced by verb phrase anaphora. The proposed framework, along with illustrative examples of its use, are presented after a brief overview of the necessary background and of the major challenges posed by verb phrase anaphora.
