Hi, sorry I've already asked few days ago, but I got no reply and I really need some help on this..
I'm running several queries against a doc collection. The queries are documents of the collection itself, I need to measure how similar is each document to the rest of the collection. Now, Lucene returns me a score per query, but I've been told such score is not comparable across queries. Is this correct ? For example, arem't these scores comparable ? query1, score:8.324234 query2, score:3.324238 If so, why not ? Isn't the cosine similarity between the query vector and collection docs vectors ? I really need a comparable measure. thanks
