AI tools for scientific literature exploration and cognitive discovery and the use of semantic technologies therein

As the amount of scientific literature, the body of both peer reviewed and open publishing literature seems to grow exponentially, the need to use search tools that employ AI to rapidly weed out less relevant material and find material that meets narrow search criteria will grow.
A plethora of tools is now available, yet it is unclear whether in all of these semantic web technologies can be or are used.
AI used for scientific literature exploration and for cognitive discovery could benefit from the use of semantic web technologies if the knowledge representation tools used by AI would incorporate such.
The W3 AIKR CG is looking into this and related issues.
General literature exploration and cognitive discovery stand to gain from semantic web enabled AI-KR, and this might be just the breakthrough application for semantic web technologies.
Has any research been done on the use of AI enabled scientific literature exploration in selected domains (disciplines), comparative studies on the use of semantic web technologies and other technologies, and developed benchmarks or metrics for measuring AI enabled literature exploration tools and semantic web technologies in such?
