Nuclei, who just launched Article Distribution Center today, informed me of a new search engine out by Microsoft named Search Result Clustering Toolbar in Microsoft Research Asia. If you take a look at the how to use the search engine page, it will describe that you can use it for;
- Query disambiguation
- Sub-topics discovery
- Fact finding of peoples
- Relationship finding of peoples
They also have a toolbar.
