Annotation tools based on the annotation graph API
Steven Bird, Kazuaki Mæda, Xiaoyi Ma, Haejoong Lee · 2001
Annotation graphs provide an efficient and expressive data model for linguistic annotations of time-series data.This paper reports progress on a complete open-source software infrastructure supporting the rapid development of tools for transcribing and annotating time-series data.This generalpurpose infrastructure uses annotation graphs as the underlying model, and allows developers to quickly create special-purpose annotation tools using common components.An application programming interface, an I/O library, and graphical user interfaces are described.Our experience has shown us that it is a straightforward task to create new special-purpose annotation tools based on this general-purpose infrastructure.
