Determining Song Similarity via Machine Learning Techniques and Tagging Information
This work addresses song similarity for recommender systems, but it is incremental as it compares standard methods without introducing new techniques.
The paper tackled the problem of determining song similarity using metadata and user tags, finding that tf-idf outperformed Word2Vec for feature vectors and k-NN models performed better than SVMs and Linear Regression.
The task of determining item similarity is a crucial one in a recommender system. This constitutes the base upon which the recommender system will work to determine which items are more likely to be enjoyed by a user, resulting in more user engagement. In this paper we tackle the problem of determining song similarity based solely on song metadata (such as the performer, and song title) and on tags contributed by users. We evaluate our approach under a series of different machine learning algorithms. We conclude that tf-idf achieves better results than Word2Vec to model the dataset to feature vectors. We also conclude that k-NN models have better performance than SVMs and Linear Regression for this problem.
