An alternative topic model based on Common Interest Authors for topic evolution analysis

作者:

Highlights:

• Authors are more topically similar when they are from multigraph clusters

• Changes in the definition of topics lead to more human-readable topics

• Topics from only meta-data of the publication records show higher topical coherence

• Use of multiple bibliographic networks is beneficial to author-based topic modeling

• Author-based topic modeling allows effective merge/split topic evolution tracking
