fuzzy_dl_owl2.fuzzydl.role_parent_with_degree

Encapsulates a weighted relationship between a role and its parent by storing the parent’s identifier and an associated degree of inclusion.

Description

Designed to represent fuzzy inheritance or hierarchical connections where a parent role contributes to a child role with a specific weight or probability, a string identifier for the parent entity is stored alongside a floating-point value that quantifies the strength or degree of this relationship. Access to these attributes enables complex reasoning about role hierarchies where relationships are not absolute but graded, allowing the system to calculate the extent to which a parent role is included. The implementation acts as a simple container, allowing other components to query the parent name and the associated metric to determine how much influence the parent role exerts.

Classes

RoleParentWithDegree

This class models a weighted hierarchical relationship between a role and its parent, capturing the extent to which the parent role is included. It stores a string identifier for the parent role alongside a floating-point degree value, which usually represents a probability or strength of inclusion within the range of 0 to 1. Users can instantiate this object with the parent name and degree, and subsequently retrieve these values via the getter methods to support complex role inheritance logic.

class RoleParentWithDegree(parent: str, degree: float)

This class models a weighted hierarchical relationship between a role and its parent, capturing the extent to which the parent role is included. It stores a string identifier for the parent role alongside a floating-point degree value, which usually represents a probability or strength of inclusion within the range of 0 to 1. Users can instantiate this object with the parent name and degree, and subsequently retrieve these values via the getter methods to support complex role inheritance logic.

Parameters:

• parent (str) – The name of the parent role.

• degree (float) – Inclusion degree of the parent role, ranging from 0 to 1.

get_degree() → float

Retrieves the current degree value associated with the instance. This method serves as an accessor for the degree attribute, returning the stored numeric value without modifying the object’s internal state. It is typically used to inspect the specific weight or metric assigned to this role.

Returns:

The degree value associated with the object.

Return type:

float

get_parent() → str

Retrieves the parent identifier associated with the current role instance. This method returns the string value stored in the parent attribute, representing the hierarchical relationship or predecessor of the current role. It is a read-only operation that does not alter the object’s state.

Returns:

The string representing the parent of the object.

Return type:

str

degree: float

parent: str
