You can declare the top result to be 100% and scale from there. "Percent relevant" is not a concept that really holds together. What does it mean to be 100% relevant? I'm not even sure what "twice as relevant" means.
A tf.idf engine, like Lucene, might not have a maximum score. What if a document contains the word a thousand times? A million times? An engine with a probabilistic model does have absolute scores, but those have other problems. wunder On 2/13/07 3:58 PM, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > Is it possible to generate a non-relative score for each result, from solr? > > I would like to be able to generate a web page that shows the first 3 > results' scores as 87%, 73%, and 72%.
