Maybe all those ones could be double checked? (already done for "Hou Zhijie").

postgres=# SELECT a1.author, a2.author,
       similarity(a1.author, a2.author) as similarity_score
FROM top_authors2025 a1
JOIN top_authors2025 a2 ON a1.author < a2.author
WHERE similarity(a1.author, a2.author) > 0.6
ORDER BY similarity_score DESC;
        author        |        author         | similarity_score

 Hou Zhijie [*]       | Zhijie Hou [*]        |                1
