Hello group,
The coord(q,d) normalisation is "a score factor based on how many of the query terms are found in the specified document." and described here:
http://lucene.apache.org/java/docs/api/org/apache/lucene/search/Similarity.html#formula_coord
Does this have a theoretical base? On what basis was the decition make to have it? Does anybody know a paper (in Information Retrieval, Information Seeking, etc.) or other more general information about this?
Best Regards,
Karl
P.S.: This is my second question about Lucene scoring (current version). It relates to the question I posted on the older scoring version. I decised to repost since most people here seemed not to read it since it relates to an old version - well actually it doesn't.
