Annotating Temporally-Anchored Spatial Knowledge by Leveraging Syntactic Dependencies
Alakananda Vempala, Eduardo Blanco · 2018
This paper presents a two-step methodology to annotate temporally-anchored spatial knowledge on top of OntoNotes.We first generate potential knowledge using syntactic dependencies, and then crowdsource annotations to validate the potential knowledge.The resulting annotations indicate how long entities are or are not located somewhere, and temporally anchor this information.Crowdsourcing experiments show that spatial inferences are ubiquitous and intuitive, and experimental results show that they can be done automatically.
