Abstract

The existence of diverse traditional machine learning and deep learning models designed for various multimodal music information retrieval (MIR) applications, such as multimodal music sentiment analysis, genre classification, recommender systems, and emotion recognition, renders the machine learning and deep learning models indispensable for the MIR tasks. However, solving these tasks in a data-driven manner depends on the availability of high-quality benchmark datasets. Hence, the necessity for datasets tailored for multimodal music information retrieval applications is paramount. While a handful of multimodal datasets exist for distinct music information retrieval applications, they are not available in low-resourced languages, like Sotho-Tswana languages. In response to this gap, we introduce a novel multimodal music information retrieval dataset for various music information retrieval applications. This dataset centres on Sotho-Tswana musical videos, encompassing both textual, visual, and audio modalities specific to Sotho-Tswana musical content. The musical videos were downloaded from YouTube, but Python programs were written to process the musical videos and extract relevant spectral-based acoustic features, using different Python libraries. Annotation of the dataset was done manually by native speakers of Sotho-Tswana languages, who understand the culture and traditions of the Sotho-Tswana people. It is distinctive as, to our knowledge, no such dataset has been established until now.© 2024 The Author(s).
