Welcome to the repository for MERP.

We use MERP to train a baseline emotion prediction model and evaluate the influence of the different profile features. We provide a thorough description of the dataset collection process, together with statistics and visualisations

Koh, E.Y.; Cheuk, K.W.; Heung, K.Y.; Agres, K.R.; Herremans, D. MERP: A Music Dataset with Emotion Ratings and Raters’ Profile Information. Sensors 2023, 23, 382. https://doi.org/10.3390/s23010382

MERP contains copyright-free full-length musical tracks with dynamic ratings on Russell's two-dimensional valence and arousal mode. It was collected through Amazon Mechanical Turk (MTurk). A total of 277 participants were asked to rate 54 selected songs dynamically in terms of valence and arousal. This dataset contains music features, as well as profile information of the annotators (their demographic information, listening preferences, and musical background were recorded).

50 songs with the most distinctive emotions were selected from the Free Music Archive by using a Triple Neural Network with the OpenSmile toolkit. Specifically, the songs were chosen to fully cover the four quadrants of the valence arousal space. 4 additional songs were selected from DEAM to act as a benchmark in order to filter out low quality ratings.
