Hierarchical Matching of Traffic Information Services Using Semantic Similarity

Algorithm 2

Functional matching.

Input:

R_Input = r_input1, r_input2, …: input function sets requested

Input == input₁, input₂, …: input function set of a service provided.

R_output= r_output1, r_output2, …: output function sets requested

Output = output₁, output₂, …: output function set of a service

: similarity threshold

weights of input and output functions

Output:

Sim_func: similarity of function sets from travelers and providers

Begin

sim(,)//function

for  i ← 1 to m  do

for  j ← 1 to n  do

if >

service_set←service_set∪e_ij

end if

end for

end for

return service_set

End
