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 )
x | ID of the origin node. |
---|---|
y | ID of the destination node. |
paths_x | Paths from the origin node following the meta-path of interest as a |
paths_y | Paths from the destination node following the meta-path of interest as a |
reference_list | Either an edge list as a |
list_type | If an edge list is provided, specify |
verbose | 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.
