When you perform a search on a non-unique name, the list of matching names usually looks like this:
Results for "harrison ford"
The title next to each name is meant to be the most representative or, as we call it, the "Best Known For" title. The idea is to help people identify each name at a glance so that they can find the desired match more easily -- in the example above, everyone should be able to decide whether they want to see the filmography of Harrison Ford the silent-movie era star or Harrison Ford the Indiana Jones star and click on the right link.
Please note that these aren't the only factors we consider, but should be enough to give an idea of the approach used to calculate the most representative titles in someone’s filmography. The top four titles with the highest score are listed in the 'Known For' category.
Since this is an entirely mathematical approach, some of our Known For choices may occasionally not be the best or most representative ones. If you are an IMDbPro member, you can make updates as outlined here. However, we aren’t able to support changes beyond this on a case-by-case basis.
However the algorithm used to select them is constantly being improved. Also, those choices are recalculated on a periodical basis, so the addition of new credits on someone's filmography will have an impact on their 'Known for' titles.
