Try it. Still in beta.
(I was asked to give a try by some people working on it :))
Good UI. Support author search/rank list, conference search/rank list, journal search/rank list, and some other cool features (try it J)
For example, top ranked authors in multimedia area:
http://academic.research.microsoft.com/CSDirectory/Author_category_13.htm (hope it was done automatically)
And it also support author profile page, for example: http://academic.research.microsoft.com/Author/951346.aspx
However, the big problem is it cannot differentiate different people with the same name either. But seems there is no a search engine can solve this problem currently.
Dataset is not complete enough. Missing papers, citations, and indexes (such as g-index and h-index) are much blow the correct ones.
For the nice feature mentioned above (author profile), the downside is that it also provides a photo of the author, however, the listed papers may come from different people with the same name. The person whose papers are listed but the photo is not his/her may get angry about it 🙂
I believe they are improving, very quickly.I heard they are updating data every week and updating features every two months.
