Domain-based Latent Personal Analysis and its use for impersonation detection in social media
Table 6: Authorship Attribution: LPA vs. baseline
['Threshold', 'Baseline Prec.', 'Baseline Recall', 'Baseline F1', 'Our method Prec.', 'Our method Recall', 'Our method F1']
Our method outperforms the baseline in all cases. It always correctly identifies the accounts whose text was halved as being the same author, with very low false-positive values, i.e., it rarely identifies different authors as the same one.
