It isn’t going to work. The score is not an absolute relevance measurement. It only says that the first document is more relevant than the second, and so on.
Scores are not comparable between different queries. The score cannot be used to say that the first hit for query A is a better match than the first hit for query B. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Apr 21, 2017, at 9:35 AM, tstusr <ulfrhe...@gmail.com> wrote: > > Since we report the score, we think there will be some relation between them. > As far as we know scoring (and then ranking) are calculated based on tf-idf. > > What we want to do is to make a qualitative ranking, it means, according to > one topic we will tag documents as "very related", "fairly related" or "poor > related".
