Finally, the similarity between sentences was calculated using both semantic and syntactic features. Results: We used 2000 randomly selected consumer questions to evaluate the system’s performance. The results show that SimQ reached the highest precision of 72.2%, recall of 78.0%, and F-score of 75.0% when using compositional feature representations. Conclusions: We demonstrated that SimQ complements the existing Q&A services of Netwellness, a not-for-profit community-based consumer health information service that consists of nearly 70,000 Q&As and serves over 3 million users each year. SimQ not only reduces response delay by instantly providing closely related questions and answers, but also helps consumers to improve the understanding of their health concerns. %M 25689608 %R 10.2196/jmir.3388 %U //www.mybigtv.com/2015/2/e43/ %U https://doi.org/10.2196/jmir.3388 %U http://www.ncbi.nlm.nih.gov/pubmed/25689608
