Again, all of that information is free. We have been getting some good coverage lately, especially about some of the new functionalities of the system. Here is a recent quote from Nature2:
“…Meanwhile, Microsoft Academic Search (MAS), which launched in 2009 and has a tool similar to Google Scholar, has over the past few months added a suite of nifty new tools based on its citation metrics (so.nature.com/u1ouut). These include visualizations of citation networks (see ‘Mapping the structure of science’); publication trends; and rankings of the leading researchers in a field.”
I would like to stress the fact that the work that we are doing here is for researchers and by researchers. That is something that we will always keep in mind when we grow and make this a more sustainable service. We are also very interested in changing our interface and not just doing citation analysis of papers, but eventually also of data. We are very interested in conducting research projects with the community. From our perspective, Microsoft Academic Search is an open platform and we are going to be as transparent as we can about our work. We want to make sure that this service will accurately represent how science and academia work. We are going to make our domain coverage more extensive. We are also working on more partnerships. For example, we are an associate member of DataCite and we are a founding sponsor of ORCID. Finally, we are tracking these and other activities to see when and how we can integrate them into our service.
