Playlist Generator An app that uses semantic search to generate afrobeat song playlists from input texts

This is a side project where I built an end-to-end machine learning application that uses a sentence transformer model hosted as a model-as-a-service. It is a simple recommendation system that tries to find afrobeat songs about a user’s sentiment by comparing the user’s text inputs to song lyrics and then return the most similar songs.

Architecture

UI

When a user enters a prompt and clicks on ‘get playlist’, a POST request containing the user’s message is sent to an API Gateway endpoint. The API Gateway triggers the lambda function , our lambda function performs semantic search against a vector database of song lyrics embeddings. The embeddings with the highest cosine similarity score are returned and the songs are returned to the frontend.
