Consider the contingency tables shown below: a) Consider the rule {p}>{q} and {r}>{s}. Compute the IS (cosine) and Interest factor for both rules. b) Given that these tables belong to the text domain and the items {p},{q},{r},{s} represent some words, which measures above would you prefer? Justify. c) Consider another measure M=sup({x,y})/sup(y) for rule {x}{y}. Compute this measure for the above rules. Which of the above measures (IS and Interest factor) do the values look similar to? Would this similarity always hold? If yes, explain otherwise explain when both would be different. Consider the contingency tables shown below: a) Consider the rule {p}>{q} and {r}>{s}.
