Practical Tools
The driver of ClinicalKey is its semantic search algorithm. The goal of semantic search is to improve search results based on context and user intention. Built into ClinicalKey are 250,000 terms and 4 million semantic relationships within those terms, which are constantly being tested and updated. Because tags need to point to clinically relevant answers—and do so 98 percent of the time, Donohue says—the system is designed to learn from every search conducted, mainly by monitoring the number of steps taken by searchers to reach desired content. In addition, doctors are asked on an ongoing basis what responses should be for different queries in specific disciplines, which helps to improve and refine the algorithm.
