Velden <p>This data set was generated to compare topic extraction solutions against each other without the availability of an authoritative ground truth. The topics were extracted from a corpus of bibliographic data from the Web of Science of publications in 59 journals in Astrophysics and Astronomy published between 2003-2011. The comparative analysis was undertaken to obtain insights into how topic extraction approaches construct topics differently and how the resulting topical structures differ.</p> Social Sciencestopic labelingbibliometric mappingvisualization en 2017-01-20 Dataset https://ssh.datastations.nl/oai doi:10.17026/DANS-ZZQ-Z4XH 2025-12-03T01:00:46Z ddi:codebook:2_5
