Conditions: study of YouTube videos with comment threads; labels from three human annotators by majority vote. Method: Shang et al. (arXiv 1907.07604, Notre Dame) propose OVCP, which ignores the title, thumbnail and video and uses features from the viewers' comment network (structure, linguistic features, metadata) fed to supervised classifiers. Data: 500 training videos (128 clickbait, 372 non-clickbait, about 2.8M comments) and a random test sample of 125 trending-page videos (13 clickbait, 112 non-clickbait). Measured result: best model (AdaBoost) reported accuracy 0.896, precision 0.50, recall 0.46, F1 0.48, above the baselines (e.g. VGG-16 thumbnail model F1 0.15, SPW18 F1 0.36).
