Claim 8:
9. The system of claim 8, wherein the computer executable code is further configured to:
receive a query sentence and a query aspect term from the query sentence;
convert the query sentence into a query dependency tree graph;
calculate a query attention matrix of the query dependency tree graph based on one-hop attention between any two of a plurality of the nodes in the query dependency tree graph;
calculate a query graph attention diffusion from the query attention matrix;
obtain a query embedding of the query dependency tree graph using the query graph attention diffusion;
classify the query aspect term based on the query embedding of the query dependency tree graph to obtain predicted classification of the query aspect term; and
label the query aspect term with the predicted classification.
