TABLE 5.

Example of a Test User (#26647) where the explanations match the favorite tags more than the recommendations: The first recommended song is a “pop” song (in bold). However, the explainability segment is both “pop” and “rock” which matches the favorite tags of the user better than the recommendation itself (value in bold), thus validating this instance.

1	Pop	Pop, rock
2	Pop, rock	Pop, rock
