If Φ(d_j,c_i) = T,then d_j is called a positive example (or a member) of c_i, while if Φ(d_j,c_i) = F itis called a negative example of c_i [2]. Figure 1 is an example, where C = {Graphics,Arch,NLP,AI,Theory}, any document in the document space should be assigned to one of these categories by the function Φ ̂ Figure1: TC example Previous…
