Hi folks! I got an interesting question from one of our librarians working on a paper, "and we want to include a bit about the qualities of a database, such as precision and recall." She is looking for references. I did the Google/Wikipedia lookups, but I'm sure she's done that too. http://en.wikipedia.org/wiki/Information_retrieval and here: http://en.wikipedia.org/wiki/Precision_and_recall If this subject resonates with anyone, give me a shout and maybe some links. Thanks! Declan
