Information Retrieval Problem

For D2, there is only one context book-gates and book-creator gates, So we form the adjusted matrix 04 d2 Book Gates Creator The unit vectors in this context are .57736 .57736 .57736 And the hybrid similarity is (using C(94,d2) = 0.75) S(94,d2) = (.707*.57726+ .707*.57736)* (0.75) = 0.61218 Now for document 3 we reform the matrix elements for that context, so we get gro Q4 Book Gates 0 Lastname author The unit vectors in this context are: .707 .707 inin in And S(94,d3) = .707*.5*2*( C(94,d3)) = .707*.5*2*(0.6) = 0.4242 Assignment : Find Sq3,2)(uses one context with correlation coeff=1, so its regular similarity as done in the past) and S(03,d3) (uses two contexts, and has an independent matrix and matrix similarity for each, context and you add up the two similarities)> note that each separate similarity is less than 1 but the combined similarity can be greater than 1.
