Resumo(s)
The rise of big data and rapid digitization in the digital media industry have made recommendation
systems essential for delivering relevant, personalized content to users. In the music streaming
sector, platforms like NetEase face the cold-start problem when recommending content to new users
with minimal interaction data. To address this, we developed and compared various techniques,
including a User Similarity-Based Recommendation Algorithm, a User Preference Elicitation
Recommendation Algorithm, a DeCS-Inspired Recommendation Algorithm, and a Discriminative
Frequent Itemsets model. Our findings show that the DeCS-Inspired model performs best in data rich scenarios, while Demographic-Based methods excel in cold-start situations. To optimize
performance, we propose a hybrid approach that combines Demographic-Based techniquesfor cold starts and transitions to the DeCS-Inspired model as user data grows.
