calculate TF$-$IDF Date of Submission: $15-$May$-2024-$ Presentation on $20-$May$-2024(1$ mark$)$

Section B: Solve the following question $(2\mathrm{.}5$ marks$)$:

Given the TF in $3$ different documents as: follows

$\backslash$table$[[$Terms$,$Query,D$\_(1),$D$\_(2),$D$\_(3)],[$W$1,2,1,0,1],[$W$2,0,3,2,0],[$W$3,1,2,0,1],[$W$4,0,0,1,0],[$W$5,0,0,1,3],[$W$6,3,1,0,0],[$W$7,1,0,3,2],[$W$8,0,4,0,0],[$W$9,1,0,0,1]],$

a$)$ Step by step, compute the TF$-$IDF for each term in all documents $(1$ mark$)$

b$)$ Step by step, compute the cosine similarity between Query and the other $3$ documents and select the best matching. $(1\mathrm{.}5$ marks$),,,$ calculate two questions them in details
