Collexis is a “leading developer of semantic technology and knowledge discovery software for research and development institutions.” Products include Expert Profiler, Reviewer Finder, BiomedExperts.com (for professional networking) and the Collexis Knowledge Engine. Darell is a frequent speaker at Information Today conferences.
