global ontology calls the synthetically global ontology to complete semantic information matching calculation.
In the SWoT, the dynamic relationships between entities are mainly affected by the
relative location (L) of entities, the time (T) of interaction between them and the
frequency (F) of interaction between them [10–12]. The dynamic relationship

specific category (Agent_category, denoted as Agc), such as Agc (A r )::= (A O |A I ), is
based on the dynamic relationships between A r and A s (r, s = 1, 2, i, j) at different L and

6 Calculations of Inter-Agents Dynamic Relationships
in SWoT
Combining with the hierarchical relationships of CO interface invocation and the FIPA
standard, this paper presents a formula for calculating the weight of dynamic relationship between Agents in SWoT:
