Data and code for "An Open Dataset of Chinese Duration Expressions"

In textual contexts, duration information is typically conveyed in two formats: numeric (e.g., 1 hour) and verbal (e.g., shortly). To analyze duration information in text, it is crucial to understand how people map duration expressions to corresponding numerical duration.

However, the literature has yet to provide lexicons supporting such conversion. Furthermore, existing databases of time-related expressions often lack information about word frequency – a robust predictor of information processing. Here, we report an open dataset of 2,101 Chinese duration expressions, each annotated with its corresponding numerical duration.
