Summary

To sum up, each of Microsoft Academic, Google Scholar and Arnetminer plays a vital role for academic search and meets the needs of different users. For simplification, we can list the strength (marked by green) and weakness (marked by red) in the table as follows.

Recommendation to Microsoft Academic

1. Make it faster and improve its update rates (actually I believe that Microsoft will have the latest proceedings at hand asap);

2. Extend the field range, such as mathematics, biology, physic after computer science is mature.

3. Offer more convient downloading experience, as it may be the primative expectation for a large range of potential users


4. Try more extended service, such as advisor-advisee relationship mining, expert finding. Explore more practical senario for such features rather than a toy example.

5. There are SNS examples present as Mendeley which may use a different strategy but Microsoft can integrates it with its LIVE account as well as its information in cmt.research.microsoft.com.

6. It is a good idea for subscription with new papers, trend, call for papers, special issues on journal and the like, it is a good idea that microsoft academic be a source center which will largely improve the user viscosity.

7. Microsoft has a clearer structure for academic search actually though part of the functionality is not mature, its object-level-vertical search. As a vertical search product that targets at more specific audience with more specific needs from its audience, sometimes user needs grows with what we can offers them. Hence, after we can satisfy the basic needs, more sophisticated needs are also crucial to satisfy its potential users.
