ELAN Analysis Companion (EAC): A Software Tool for Time-course Analysis of ELAN-annotated Data

Abstract

LAN is a widely used and free (in both senses) annotation software for behavioral or other events that unfold over time. We report on and release a stand-alone program that expands on ELAN's capabilities in two ways: 1) it allows the researcher to plot and export time-course analysis data directly from ELAN's native annotation files, allowing for hassle-free data extraction in the time domain, e.g. for visual-world paradigm studies; and 2) it allows the researcher to weight ELAN's built-in annotator reliability rating based on the duration of the coded events. This software is released under an open license.
