Researchers have explored using cognitive signals from human reading, specifically electroencephalography (EEG) and eye-tracking data, to improve automatic keyphrase extraction (AKE) from microblogs. The study, utilizing the ZuCo corpus, found that EEG signals provided the most significant gains in AKE performance, outperforming eye-tracking alone. While combining both signal types showed some complementarity, their performance fell between the individual signals, suggesting potential redundancy or noise. The findings highlight the value of EEG in AKE and suggest further investigation into multimodal cognitive signals. AI
