Filed under: Precision,Recall — Patrick Durusau @ 7:36 pm

High precision means resources are missed.

High recall means sifting garbage.

Q: Based on what assumption?

A: No assumption, observed behavior of texts and search engines.

Q: Based on what texts?

A: All texts, yes, all texts.

Q: Texts where same subjects have different works/phrases and same words/phrases mean different subjects?

A: Yes, those texts!

Q: If the subjects were identified in those texts, we could have high precision and high recall?

A: Yes, but not possible, too many texts!

Q: If the authors of new texts were to identify….

A: Sorry, no time, have to search now. Good-bye!
