Abstract

OBJECTIVE: To determine whether a factorized version of the complement naïve Bayes (FCNB) classifier can reduce the time spent by experts reviewing journal articles for inclusion in systematic reviews of drug class efficacy for disease treatment. DESIGN: The proposed classifier was evaluated on a test collection built from 15 systematic drug class reviews used in previous work. The FCNB classifier was constructed to classify each article as containing high-quality, drug class-specific evidence or not. Weight engineering (WE) techniques were added to reduce underestimation for Medical Subject Headings (MeSH)-based and Publication Type (PubType)-based features. Cross-validation experiments were performed to evaluate the classifier's parameters and performance. MEASUREMENTS: Work saved over sampling (WSS) at no less than a 95% recall was used as the main measure of performance. RESULTS: The minimum workload reduction for a systematic review for one topic, achieved with a FCNB/WE classifier, was 8.5%; the maximum was 62.2% and the average over the 15 topics was 33.5%. This is 15.0% higher than the average workload reduction obtained using a voting perceptron-based automated citation classification system. CONCLUSION: The FCNB/WE classifier is simple, easy to implement, and produces significantly better results in reducing the workload than previously achieved. The results support it being a useful algorithm for machine-learning-based automation of systematic reviews of drug class efficacy for disease treatment.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Another text mining algorithm achieved workload savings ranging from 8.5 to 62% with 15 test datasets, similar to our findings with Abstrackr (9 to 80%), but their results were based on a threshold of a minimum 95% recall of relevant studies, which is too low for systematic reviews.

    “Whilst another text mining algorithm [17] achieved workload savings ranging from 8.5 to 62 % with 15 test datasets, which are similar to our findings with Abstrackr (9 to 80 %), their results were based on a threshold of a minimum 95 % recall of relevant studies, which is too low for systematic reviews.”
  • This study and others that have evaluated semi-automated screening with support vector models, semantic vector models, and complement naïve Bayes models indicate that considerable workload savings can be achieved.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
