Algorithm 3 Goal Annotation Algorithm for Case B.II
Require: weight parameters γ, δ
initialize value of weight f orarti f actonto, weight f orarti f actname as 0
Arraya f[] is a set of artifacts associated with av through has_Artifact
for each a f in a f [] do
onto = OD(a f) {OD(a f) gets the domain ontological concept annotated to a f }
for each target artifact a f ′ of a g in goal ontology do
r = SR(a f , onto) {SR(ar, onto) gets the semantic relationship between a f and
onto}
initialize σ, τ as 0
if onto equals a f ′ then
if r is "same_as" then
σ = 1
else if r is "kind_of" then
σ = 0.8
else if r is "phase_of" then
σ = 0.5
end if
end if
weight f orarti f actonto = weight f orarti f actonto+σ
if a f .name equals a f ′ .name by string match then
τ = 1
else if a f .name partly equals a f ′ .name by string match then
τ = 0.5
end if
weight f orarti f actname = weight f orarti f actname+τ
end for
end for
return γ ∗ weight f orarti f actonto+ δ ∗ weight f orarti f actname
