2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/31038Four diverse tools built on the Annotation Graph Toolkit are described. Each tool associates linguistic codes and structures with time-series data. All are based on the same software library and tool architecture. TableTrans is for observational coding, using a spreadsheet whose rows are aligned to a signal. MultiTrans is for transcribing multi-party communicative interactions recorded using multi-channel signals. InterTrans is for creating interlinear text aligned to audio. TreeTrans is for creating and manipulating syntactic trees. This work demonstrates that the development of diverse tools and re-use of software components is greatly facilitated by a common high-level application programming interface for representing the data and managing input/output, together with a common architecture for managing the interaction of multiple components.7 pages, 7 figuresComputation and LanguageSoundD.2.13; H.5.5; I.2.7text
