Remarks¶
Efferent coupling (Ce): Number of entities that an entity depends on.
Afferent coupling (Ca): Number of entities that depend on an entity.
Instability (I): Computed as Ce / (Ce + Ca). Measures the entity resilience to change. Ranging from 0 to 1, with 0 indicating a maximally stable entity and 1 indicating a maximally unstable entity. Ideally, an entity is either maximally stable or maximally unstable.
Abstractness (A): Computed as the ratio between the number of static predicates with scope directives without a local definition and the number of static predicates with scope directives. Measures the rigidity of an entity. Ranging from 0 to 1, with 0 indicating a fully concrete entity and 1 indicating a fully abstract entity.
Entity score: Represented as the compound term ce_ca_i_a(Ce,Ca,I,A).
Dependencies count: Includes direct entity relations plus calls or dynamic updates to predicates in external objects or categories.
