OBJECTIVE: In a previous study, we investigated a sentence classification model
that uses semantic features to extract clinically useful sentences from UpToDate,
a synthesized clinical evidence resource. In the present study, we assess the
generalizability of the sentence classifier to Medline abstracts. METHODS: We
applied the classification model to an independent gold standard of high quality
clinical studies from Medline. Then, the classifier trained on UpToDate sentences
was optimized by re-retraining the classifier with Medline abstracts and adding a
sentence location feature. RESULTS: The previous classifier yielded an F-measure
of 58% on Medline versus 67% on UpToDate. Re-training the classifier on Medline
improved F-measure to 68%; and to 76% (p<0.01) after adding the sentence location
feature. CONCLUSIONS: The classifier's model and input features generalized to
Medline abstracts, but the classifier needed to be retrained on Medline to
achieve equivalent performance. Sentence location provided additional
contribution to the overall classification performance.
