I have a platform idea, I need feedback

Problem statement: it’s hard to find researchers of specific area, which discourages students to even start looking for research opportunities. The reason for that is because people often look into their own academic circle, and the resource available is simply not enough.

Solution: by scraping Google scholar, generate detailed tag of sub areas for each professors, make a search system for that which will display the most important works of a researcher and what they are working on recently. If possible, invite the researchers to use the platform to add tags of traits they are looking for in students.

I have quite polarized feedback right now, one is the subarea tagging is really useful and academic circle is a problem, other is this is completely useless.

Please let me know what you think.
