Hi, I am using MoreLikeThis handler to get related documents for a given document. To determine if I am getting good results or not, here is what I do:
The same original document should be returned as a top match. If it is not, then there is some problem with the relevancy. Then, as same input document will be 100% match with itself, we can use its absolute score to compare how other documents (ranked 2nd, ranked 3rd and so on) are doing in terms of relevancy by comparing their scores to the score of the top result which is the same input document Is this a good idea? Do you see any flaw in this logic?
