Hi Solr users,
I have a question on the relatedness and Semantic Knowledge Graphs feature in Solr. While the results are good with the out of box provision, I need some tweaking on the ability to specify filters or parameters based on only the foreground count. Right now only the min_popularity parameter is available which applies to both the foreground dataset or the background one. The white paper from Trey Grainger and his team mention that the z score is used to calculate the score. As per my understanding, the z score assumes a normal distribution and is applicable when sample size>30 which I assume is the foreground count. So I would like to control this value with a parameter or filter. Right now I am getting the approximate count by doing a reverse calculation on the foreground popularity and the background size to get the foreground count. Kindly correct me if my understanding is different from what it should be.
