For a long time I have been interested in visualizing the network of all active academics of a certain discipline worldwide (e.g. computer science, mathematics, or by a set of keywords).
I imagine a typical zoomable map of the world, with discs on cities proportionnal to the number of folks working there in that field.
By active, let's say "people who have (pre-)published within the past 7 years, or doing a PhD in the area". So the input would be a list of authors taken from journals and preprint servers, plus the list of all current graduate students from university websites.
Would there be legal problems to create such a list? If no, does it already exist somewhere? If there are legal problems, would a fully anonymized list (e.g. just ranges of numbers: 0-4; 5-9;...) be okay?
