This is just a follow up to the mail I sent regarding the
plotting of precision/recall curves…I realize that the example in the
slides shows 10 relevant documents and it may seem as if this is the reason for
plotting the 11 point curve however, this is not the case… 11 point curves are frequently used irrespective of the
number of relevant documents…for some additional information please refer
to these links, send me a mail, or stop by and see me http://nlp.stanford.edu/IR-book/html/htmledition/evaluation-of-ranked-retrieval-results-1.html Garrett |
