I like the general direction of your approach (especially using w+ and w-), but there are some problems... Take an example: S1: AGIers are usually nerds S2: Nerds are usually socially awkward ----------------------------------------------------- S: AGIers are probably socially awkward Suppose the frequencies of S, S1 and S2 are f, f1 and f2, resp. If you draw the Venn diagram, you'd find that one piece is missing if we want to deduce f, namely the portion of AGIers who are not nerds but who are socially awkward. In your paper you seem to suggest a heuristic rule: f = f1 f2 / (f1 + f2 - f1 f2) I'm not saying the rule is bad, just wondering what kind of assumptions you're making?
