Query Relaxation
Daniel Tunkelang

Excellent piece Daniel, and quite timely for a project I have upcoming where I hope to apply some of these ideas in practice. Some of the transformations are culturally dependent though — ‘polo’ to me means a game first, a confection second, and a shirt a very distant third :)

I am also curious as to the extent to which it is possible to automatically determine whether the quantity/quality of results is sufficient for relaxation to be productive, or whether explicit human interaction remains the gold standard?

[BTW the ‘query expansion’ link in the middle of the piece appears broken]

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
