Create tool to calculate discounted cumulative gain and normalized DCG

Create an application (perhaps in Excel?) that will allow for the objective rating of sets of search results. Please see [login to view URL] We wish to calculate DCG and NDCG ## Deliverables We have search results rated on a four level scale 0 to 3 inclusive where 3 is highest relevance, and 0 is no relevance. We will enter the data manually, for both relevance score and distance from top result. Application will need to calculate DCG and NDCG for no more than 20 results per test.
