Q. (47) 2. Premises. The collection of premises expressed in a naturallanguage constitutes the initial data set (IDS). 3. Additional premises which are needed to arrive at an answer to q. These premises constitute the external data set (EDS). Addition of EDS to IDS results in what is referred to as the augmented data set (IDS+ ). 49 Example. Assurne that the initial data set consists of the propositions p1 : Carollives near Berkeley, p2 : Pat lives near Palo Alto. Suppose that the question is: How far is Carol from Pat?
