[FRIAM] neural/symbolic integration workshop

[Stephen Guerin]

Thanks for forwarding, Jon. I did a 5-minute skim and would agree with
Glen. I would add that a bidirectional path tracer would reverse the
meaning of the semantic edge. eg, the next sentence after Glen's quote:

Although we have directed edges in the schema graph, we traverse it
in an undirected manner: from any vertex v, we visit its neighbors
from both incoming and outgoing edges. R3 shows an example
path containing an inherited edge,
    Actor ---worksAt −−→ Organization


The inverse would be something like
             Actor <---Employs --- Organization

This is equivalent to changing the lane direction in a traffic routing
algorithm when flood-filling backwards during the bidirectional path
tracing.
