Use the PathSim metric to compute a meta-path based similarity score. Please note that PathSim can ONLY be used for symmetric meta-paths.
get_pathsim(
x,
y,
paths_x,
paths_y,
reference_list = NULL,
list_type = NULL,
verbose = TRUE
)
ID of the origin node.
ID of the destination node.
Paths from the origin node following the meta-path of interest as a data.table
.
Paths from the destination node following the meta-path of interest as a data.table
.
Either an edge list as a data.table
which must contain the columns Origin
,
Destination
, OriginType
, DestinationType
, and EdgeType
, or a neighbor reference object constructed
by get_neighbor_list()
.
If an edge list is provided, specify "edge"
. If a neighbor list is provided, specify "neighbor"
.
Should the intermediate calculations be printed to the console?
A list with two elements:
The name of the similarity metric (i.e., "PathSim"
).
The PathSim similarity score.
