HED LANG – A Hierarchical Event Descriptors library extension for annotation of language cognition experiments

Résumé fourni par la source

Experimental design in language cognition research often involves presenting language material whilemeasuring associated behavior and/or neural activity. To make the collected data easily and fullyanalyzable by both the original data authors and others, it is important to have detailed informationabout the stimulus presentation events, including the nature and properties of the presented stimuli,using a common vocabulary and syntax. We present HED LANG, a library extension of the HierarchicalEvent Descriptors (HED) event annotation schema for time series behavioral and neuroimaging data.HED LANG provides an open source, standardized vocabulary for building detailed, human- andmachine-actionable annotations for language cognition datasets. It builds on existing annotationsystems in linguistics and is supported by a suite of HED tools for annotating, validating, searching,and characterizing HED-tagged datasets. HED LANG is specific enough to allow event data annotationat the range of levels needed to support many current research paradigms and analyses. Both HEDand HED LANG are open to community input and participation, enabling them to evolve withcontinuing developments in language cognition research.
