Systems approaches to studying drug-side-effect (drug-SE) associations are
emerging as an active research area for drug target discovery, drug
repositioning, and drug toxicity prediction. However, currently available drug-SE
association databases are far from being complete. Herein, in an effort to
increase the data completeness of current drug-SE relationship resources, we
present an automatic learning approach to accurately extract drug-SE pairs from
the vast amount of published biomedical literature, a rich knowledge source of
side effect information for commercial, experimental, and even failed drugs. For
the text corpus, we used 119,085,682 MEDLINE sentences and their parse trees. We
used known drug-SE associations derived from US Food and Drug Administration
(FDA) drug labels as prior knowledge to find relevant sentences and parse trees.
We extracted syntactic patterns associated with drug-SE pairs from the resulting
set of parse trees. We developed pattern-ranking algorithms to prioritize
drug-SE-specific patterns. We then selected a set of patterns with both high
precisions and recalls in order to extract drug-SE pairs from the entire MEDLINE.
In total, we extracted 38,871 drug-SE pairs from MEDLINE using the learned
patterns, the majority of which have not been captured in FDA drug labels to
date. On average, our knowledge-driven pattern-learning approach in extracting
drug-SE pairs from MEDLINE has achieved a precision of 0.833, a recall of 0.407,
and an F1 of 0.545. We compared our approach to a support vector machine
(SVM)-based machine learning and a co-occurrence statistics-based approach. We
show that the pattern-learning approach is largely complementary to the SVM- and
co-occurrence-based approaches with significantly higher precision and F1 but
lower recall. We demonstrated by correlation analysis that the extracted drug
side effects correlate positively with both drug targets, metabolism, and
indications.
