Based on the ranking obtained in question lc.ii above
and the relevant documents are d3 and d l. Calculate the precision
and recall on the top 5 rank. Draw the 11th interpolated
recall-precision graph. [7]
cos(Θ)qd1=(1*0+0*0+1*1+0*1+0*0+1*0)/√3*√2=1/√6=0.40
cos(Θ)qd2=(1*1+0*0+1*0+0*0+0*0+1*0)/√3*√1=1/√3=0.57
cos(Θ)qd3=(1*2+0*1+1*1+0*1+0*0+1*2)/√3*√11=5/√33=0.87
cos(Θ)qd4=(1*4+0*1+1*0+0*0+0*0+1*2)/√3*√21=6/√63=0.755
cos(Θ)qd5=(1*3+0*0+1*0+0*1+0*1+1*2)/√3*√15=5/√45=0.745
