Claim 11:
12. The method of claim 11, wherein the step of calculating the graph attention diffusion comprises:
calculating diffusion attention matrix Ã(l) by: Ã(l)=Σhop=0∞α(1−α)hopAhop(l)α Σ (0, 1], wherein hop is a positive integer in a range of 2-12, and α is an attention decay factor; and
calculating the graph attention diffusion H(l+1) by: H(l+1)=Ã(l)H(l), wherein H(l) is input dependency tree graph embedding of the l-th GDT layer.
