get_edge_features: Get information about edges

In lmyint/rsemmed: An interface to the Semantic MEDLINE database

Description

Search for nodes by name using regular expressions or which match given semantic types. Perform anti-matching by setting match = FALSE.

Usage

get_edge_features(
    graph,
    include_degree = FALSE,
    include_node_ids = FALSE,
    include_num_instances = FALSE
)

Arguments

graph	The SemMed graph
include_degree	If TRUE, include information on head/tail node degrees.
include_node_ids	If TRUE, include the ID numbers of head/tail nodes.
include_num_instances	If TRUE, include information on the number of times a predication was observed in the Semantic MEDLINE database.

Value

A tbl where each row corresponds to an edge in the Semantic MEDLINE graph. The ordering of the rows corresponds to E(graph). Features (columns) always returned include the name and semantic type of the head (subject) and tail (object) nodes.
