An Ontology-Based Architecture Pattern Modeling Method

Abstract

The invention discloses an ontology-based architectural pattern modeling method. According to the method, description logic is used to perform concept modeling of an architectural pattern, a domain knowledge model is further introduced, finally a mapping relation between a high-level abstract concept and system realization is established, and therefore the model is applied to recognition of the architectural pattern. Considering extension and reuse problems of domain knowledge, the domain knowledge is organized into a netlike hierarchical structure during modeling. In the structure, a conceptmodel is at a high level, more domain knowledge is combined step by step at all lower levels to explain the high-level concept. New knowledge can be incrementally added into any node at any level andalso can be selectively reused to establish a new concept. The ontology-based architectural pattern modeling not only has the abstracting ability of concept modeling but also can utilize the domain knowledge to serve architectural pattern recognition, and therefore the automation degree and precision of architectural pattern recognition are improved.

Description

technical field [0001] The invention relates to the field of reverse engineering of software, in particular to an architecture pattern modeling method based on ontology. Background technique [0002] The software architecture is the main technical outcome of the early development phase, describing the functional elements of the system and their interrelationships. In system architecture, information about the patterns used is an important part of architectural knowledge today. Many architectural design methodologies consider architectural patterns as fundamental design concepts because architectural patterns provide proven solutions to recurring design problems in the context of systems. Information about the patterns used in a product can also provide valuable insights into software product evaluation system quality attributes, i.e., performance and reliability, etc. Therefore, a deep understanding of system architecture patterns is crucial during the development, mainten...

AI Technical Summary

Problems solved by technology

Unfortunately, architecture documents are often outdated, updated with significant delays, and inconsistent in detail and form

Furthermore, the architecture of a system is often documented as it is developed, and the evolutionary process leads to decay of the initial design and leads to a separation between the design and the built architecture

In other cases, the development team may lose documents during long-term maintenance and handover, or they are not always available, such as some open source software
