Calculate the Resnik or Lin semantic similarity for an ontology. — calculate_semantic_sim

This function calculates the specified semantic similarities for the whole ontology and adds it to the class.

Usage

calculate_semantic_sim_onto(
  object,
  sim_type = c("resnik", "lin", "combined"),
  .verbose = TRUE
)

Arguments

object: OntologySim class. See OntologySim().
sim_type: String. One of c("resnik", "lin", "combined").
.verbose: Boolean. Controls the verbosity of the function.

Value

The class with added semantic similarities to the properties.

Examples

# Resnik similarities for the whole ontology stored in the class
onto <- data.table::data.table(
  parent = c("a", "b", "b", "b", "c"),
  child = c("b", "c", "d", "e", "f"),
  type = c("part_of", "part_of", "part_of", "is_a", "is_a")
)
onto_obj <- pre_process_sim_onto(
  OntologySim(onto, .verbose = FALSE),
  .verbose = FALSE
)
calculate_semantic_sim_onto(onto_obj, sim_type = "resnik", .verbose = FALSE)
#> OntologySim class:
#>  Size of the ontology: 5.
#>  Semantic similarities calculated: Yes.
