SEGMENTAÇÃO ACÚSTICA BASEADA EM K-MEANS PARA MITIGAÇÃO DO VIÉS DE POPULARIDADE EM RECOMENDAÇÕES MUSICAIS

Resumo

Nesta pesquisa, propomos um Sistema de Recomendação Contextual baseado em clusterização acústica. O modelo utiliza o algoritmo K-Means (k = 6) para segmentar um vasto catálogo musical do Spotify em perfis sonoros estatisticamente distintos. A validação estatística por ANOVA One-Way confirmou a distinção de todos os seis clusters (p < 0, 001), garantindo a solidez da segmentação e revelando a estrutura da Cauda Longa. O sistema mapeia esses clusters para contextos de uso (e.g., "Foco"→ Cluster Instrumental) para mitigar o viés de popularidade inerente aos dados. A abordagem demonstrou ter o potencial de elevar o valor de descoberta das recomendações, promovendo a diversidade e atacando a falha de sistemas baseados unicamente em popularidade.
