A notable consequence of our obsession with research assessment is an enhanced role for research management within the institution. Suddenly all the senior managers want to know how best to capitalize on our existing strengths to make the most of future funding and publishing opportunities. And that means knowing what our strengths are. And that means knowing what our researchers do. And how they work together to do it best. And that's where the repository comes in - capturing our institution's intellectual outputs and providing services over them.
So my boss has asked for our repository to provide an Expertise Finder - for him to be able to find out what groups of people are working together in any particular area.
All we had to do was put that functionality into an export plugin so that the authors from any set of papers can be visualised in the same way. That way you can find out who is involved in a specific topic like "Web Science" by doing a search for "Web science" and exporting the results as an "author cloud". You can try it out on our repository.
