In ayushnoori/metapaths: Meta-Path-Based Network Similarity

Compute meta-path based similarity scores between two sets of nodes using various meta-paths.

Description

Given a series of specified meta-path(s), similarity metric(s), and aggregation method(s), compute the meta-path based similarity score between two nodes.

Usage

compare_mps(
  set1,
  set2,
  mps,
  metric = c("pc", "pathsim", "npc", "dwpc"),
  method = c("maximum"),
  node_list,
  edge_list = NULL,
  neighbor_list = NULL,
  check = TRUE,
  verbose = TRUE
)

Arguments

set1	IDs of node set #1 as a vector.
set2	IDs of node set #2 as a vector.
mps	List of meta-paths, where each meta-path is a vector of node types (e.g., c("TypeA", "TypeB", "TypeC")).
metric	A vector of permissible similarity metrics (e.g., c("npc", "dwpc")), see defined metrics below: Path Count Specify "pc", corresponding to get_pc(). Normalized Path Count Specify "npc", corresponding to get_npc(). Degree-Weighted Path Count Specify "dwpc", corresponding to get_dwpc(). PathSim Specify "pathsim", corresponding to get_pathsim().
method	A vector of permissible aggregation methods (e.g., c("shortest")), see defined metrics below: Shortest Specify "shortest", corresponding to aggregate_shortest().
node_list	Node list as a data.table which must contain the following columns: Node Node IDs (corresponding to either Origin or Destination in the edge list). NodeType Node types (corresponding to either OriginType or DestinationType in the edge list).
edge_list	Edge list as a data.table which must contain the following columns: Origin IDs of the origin nodes for each edge. Destination IDs of the destination nodes for each edge. OriginType Types of the origin node for each edge. DestinationType Types of the destination node for each edge. EdgeType Types of each edge.
neighbor_list	Neighbor reference object constructed by get_neighbor_list().
check	Should type checking be performed? Default is TRUE.
verbose	Should the intermediate calculations be printed to the console?

Value

A list with six elements:

Set1

IDs of node set #1 provided (i.e., set1).

Set2

ID of node set #2 provided (i.e., set2).

Details

Intermediate computations produced by get_similarity() and compare_sets().

SetSimilarity

Aggregate set similarity score(s).
