Discounted cumulative gain (DCG) is a measure of ranking quality. In information retrieval, it is often used to measure effectiveness of web search engine algorithms or related applications. Using a graded relevance scale of documents in a search-engine result set, DCG measures the usefulness, or gain, of a document … See more Two assumptions are made in using DCG and its related measures. 1. Highly relevant documents are more useful when appearing earlier in a search engine result list (have higher ranks) 2. Highly relevant … See more 1. Normalized DCG metric does not penalize for bad documents in the result. For example, if a query returns two results with scores 1,1,1 … See more Presented with a list of documents in response to a search query, an experiment participant is asked to judge the relevance of each document to the query.
