Gain (information retrieval)

 * – ( View AfD View log  Stats )

What this article describes is nothing more than "relative improvement over chance", an idea which is not specific to information retrieval (nor even to computer science) and which is probably not complex enough to warrant its own article. In fact, it's sufficiently trivial or obvious that it doesn't seem to be covered in the surveys and introductory books I've consulted (such as Manning et al.'s Introduction to Information Retrieval). To the extent that there is any material here worth salvaging, it would be better placed in precision and recall.

 * Delete. Much of this article is true, except that gain is not necessarily defined in comparison to a random baseline and is not specific to classifiers even in IR. But the concept of gain is not in the glossary from Modern Information Retrieval either, nor in the index of my 1999 edition, nor can I find a research paper that makes a point of defining it.
