HAC features and metadata for the ACORNS Caregiver dataset

Acorns project; Mangin, Olivier

Histograms of co-occurence features from the Caregiver dataset.

Each files contains the features corresponding to one speaker. The features were extracted using matlab code from the ACORNS project, except for the ones postfixed with "_python" that were extracted with code from

The .json files contains metadata for the the datasets. See for more information on the format.

For more information and data, the English part of the ACORNS CAREGIVER corpus is available from the language archive (TLA -MPI for psycholinguistics Nijmegen) for reproducibility and transparency reasons in accordance with the agreements that were obtained from the speakers.
