Description

SUTime is a library for recognizing and normalizing time expressions. That is, it will convert next wednesday at 3pm to something like 2016-02-17T15:00 (depending on the assumed current reference time). SUTime is available as part of the Stanford CoreNLP pipeline and can be used to annotate documents with temporal information. It is a deterministic rule-based system designed for extensibility. The currently available rule support only English.

SUTime was developed using TokensRegex, a generic framework for definining patterns over text and mapping to semantic objects. An included set of powerpoint slides and the javadoc for SUTime provide an overview of this package.

SUTime was written by Angel Chang. These programs also rely on classes developed by others as part of the Stanford JavaNLP project.

There is a paper describing SUTime. You’re encouraged to cite it if you use SUTime.
