Which keywords describe research in Greece?

By fractional works in 2022–2025, weighted toward what it does more of than the world: Epidemiology, Machine Learning, Deep Learning, Climate Change, Sustainability, Inflammation, Cardiovascular Disease and Environmental Impact.

▲ more of its work than of the world’s◆ about the world’s share▼ less than the world’s

Size is fractional works in 2022–2025 in the topics tagged with each word; colour is the word's share of this country's work against its share of the world's. The 40 words are chosen for being large and distinctive. Each links to the topic it comes from most.

How many world-class institutions does Greece hold?

Average quality and elite capacity disagree by construction, and both are worth knowing: the first is decided by a country’s whole institution population, the second counts the institutions it holds at the top. One square per institution.

101st to 500th2501st to 1,000th2

Bands are exclusive, so the squares add up to 4 — the institutions it holds in the world top 1,000 — and not to four times it.

Which universities in Greece lead research?

National and Kapodistrian University of Athens, Aristotle University of Thessaloniki and University of Patras rank highest in Greece on research quality in 2022–2025.
