How to report the Interests entered in the Opportunity Marketplace

Content (required):

Hi,

we would like to know if there is the possibility to build a report (BI or OTBI, it's the same thing), which allows us to collect the pieces of information entered by an employee in the 'Update interests' area, in the opportunity Marketplace page (see the screenshot). If yes, could you provide us the name of the 'Subject Area' (for OTBI report), or the name of the table (for BI report), which contain the aforementioned pieces of information?

Hoping someone has some suggestions.

Thanks a lot,
