Automatic recognition of self-acknowledged limitations in clinical research literature.

ABSTRACT: Objective:To automatically recognize self-acknowledged limitations in clinical research publications to support efforts in improving research transparency. Methods:To develop our recognition methods, we used a set of 8431 sentences from 1197 PubMed Central articles. A subset of these sentences was manually annotated for training/testing, and inter-annotator agreement was calculated. We cast the recognition problem as a binary classification task, in which we determine whether a given sentence from a publication discusses self-acknowledged limitations or not. We experimented with three methods: a rule-based approach based on document structure, supervised machine learning, and a semi-supervised method that uses self-training to expand the training set in order to improve classification perf
