WebOct 26, 2016 · For binary relevance, we need a separate classifier for each of the labels. There are three labels, thus there should be 3 classifiers. Each classifier will tell weather the instance belongs to a class or not. For example, the classifier corresponds to class 1 (clf[1]) will only tell weather the instance belongs to class 1 or not. ... Web2. The relevance property is assumed to be binary. Either of these assumptions is at the least arguable. We might easily imagine situations in which one document’s relevance can only be per-ceived by the user in the context of another document, for example. Regarding the binary property, many recent experimental studies have preferred a ...
