The Annotation Graph Toolkit (Version 1.0): Application Developer’s Manual

Annotation graphs provide an efficient and expressive data model for linguistic annotations of time-series data. This technical report describes a complete software infrastructure supporting the rapid development of tools for transcribing and annotating time-series data. This general-purpose infrastructure uses annotation graphs as the underlying model, and allows developers to quickly create special-purpose annotation tools using common components. The architecture, the application programming interface and a file I/O library are explained. A toy example of how to build a specialpurpose annotation tool using this general-purpose infrastructure is given. c Copyright 2001 University of Pennsylvania.
