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(More)
OBJECTIVE To determine whether the automatic classification of documents can be useful in systematic reviews on medical topics, and specifically if the performance of the automatic classification can be enhanced by using the particular protocol of questions employed by the human reviewers to create multiple classifiers.

The purpose of this systematic review of the scientific medical literature was to survey the range of measures assessing the quality of breast cancer care in women and to characterize specific parameters potentially affecting their suitability for wider use. The review was conducted by the University of Ottawa Evidence-based Practice Center (UO-EPC).(More)
The purpose of this work is to reduce the workload of human experts in building systematic reviews from published articles, used in evidence-based medicine. We propose to use a committee of classifiers to rank biomedical abstracts based on the predicted relevance to the topic under review. In our approach, we identify two subsets of abstracts: one that(More)
Breast cancer in women is increasingly frequent, and care is complex, onerous and expensive, all of which lend urgency to improvements in care. Quality measurement is essential to monitor effectiveness and to guide improvements in healthcare. Ten databases, including Medline, were searched electronically to identify measures assessing the quality of breast(More)
