IEEE/ICACT20230130 Question.11 Questioner: yangkoon@gmail.com 2023-02-22 오후 12:58:10	IEEE/ICACT20230130 Answer.11 Answer by Auhor liufan@nus.edu.sg 2023-02-22 오후 12:58:10
I heard that the Lucene score was calculated to determine the popularity of the book, but how can I judge the accuracy of this?	Thanks for your question. We compared the hybrid algorithm with popularity (including both item-based and ALS) with the algorithm without popularity. The former is slightly better than the latter.
