Meet LETOR 4.
0 — a big new dataset for search experiments
Scientists made a fresh set of data to help computers learn how to rank web pages, and it's called LETOR 4.
0.
This release is not just a small update, it's a new start built from a huge web archive of about 25 million pages.
The team used two groups of search queries named MQ2007 and MQ2008, so there are many real questions inside, roughly 1700 in one set and 800 in the other.
Think of it like a training ground where researchers can test and compare methods easily — that's why people call it a benchmark.
The files include page examples, labels that show what’s relevant, and ways to split data for fair tests.
If you work with search or curious about how recommendations and search rankings get better, this dataset makes experiments simpler.
The creators want it to be useful, so please send feedback to the team and share ideas, they will listen.
Try it out, play with it, and maybe you’ll help make search smarter.
