Improve frontend

View errors

• https://rise-services.rise.unibas.ch/benchmarks/p/book_advert_xml/ works but misses content

Test runs pages

• test time not displayed
• test results not displayed
• cost and pricing not displayed

Desiderata

• Top runs/latest runs tables should always contain test IDs as col 1
• Test IDs in tables should link to corresponding test views
• For each test, view results (comparison predicted answers/ground truth per image/text unit).
• Have numerical leaderboard with normalized scores over all models on main landing page.
• Benchmarking landing pages (eg https://rise-services.rise.unibas.ch/benchmarks/p/bibliographic_data/) should repeat information found in benchmarks overview (https://rise-services.rise.unibas.ch/benchmarks/p/benchmarks/) namely links to test results, data and tags, and perhaps also top results
