Knowledge base design for network service composition using semantic web languages

Abstract

We propose a knowledge base design by using Semantic Web languages to provide automatic service composition for network operation support. A knowledge base is designed based on the Shared Information/Data (SID) model described in OWL. In this design, a Service in the SID model (e.g., QoS) is defined as a network service that represents a logical functionality of resources having some operation services. An operation service is defined as an OWL-S Service for operating each network service. In addition, constraints on resources that implement particular network services (e.g., QoS on Trails) having particular operation services are studied. We used the proposed method to construct a practical knowledge base for a specific QoS services case. As a result, we verified that reasoning on the constraints works successfully by using a general reasoning tool.
