Abstract.
We participated (as Team 9) in the Article Classification Task: binary classification of full-text documents relevant for protein-protein interaction of the Biocreative II.5 Challenge. We used two distinct classifiers for the online and offline challenges: (1) the lightweight Variable Trigonometric Threshold (VTT) linear classifier we successfully introduced in BioCreative 2 for binary classification of abstracts, and (2) a novel Naive Bayes classifier using features from the citation network of the relevant literature. We supplemented the supplied training data with full-text documents from the MIPS database. The lightweight VTT classifier was very competitive in this new full-text scenario: it was a top performing submission in this task, taking into account the rank product of the Area Under the interpolated precision and recall Curve, Accuracy, Balanced F-Score, and Matthew’s Correlation Coefficient performance measures. The novel citation network classifier for the biomedical text mining domain, while not a top performing classifier in the challenge, performed above the central tendency of all submissions and therefore indicates a promising new avenue to investigate further in bibliome informatics.
