Embodiment Construction

[0019] A software system fault detection method based on dynamic description logic and case reasoning, comprising the following steps:

[0020] Step 1, use the dynamic description logic of the dynamic dimension to describe the problems encountered in the process of program operation, that is, the execution of the program is regarded as the action of state transition, the state transition is regarded as caused by the action, and the state transition Add semantic information;

[0021] Step 2, use the problems encountered during the running of the current program as a new case, and use the state and action sequence of the new case as the input of this case retrieval;

[0022] Step 3: Calculate the similarity between the state of the new case and the cases in the case base, and select the case from the case base whose similarity with the new case reaches the state similarity matching threshold, and store it in the preliminary result set; if the case If the similarity between all ...

Abstract

The invention discloses a software system fault detection method based on dynamic description logic and case-based reasoning. Based on states, an action theory of the dynamic description logic is adopted to describe the problem, execution of a program function module is regarded as an action changing the states, state conversion is regarded as change caused by the action, semantic information between the states is added, and the modeling complex is reduced. Fault cases are managed by combining the description capacity and reasoning capacity of the dynamic description logic and a case-based reasoning technology, and experience support for the method is provided for solution of new faults to be occurred of a system. Case retrieval matched with action sequences is added to improve the precision ratio of the case retrieval of the system faults. After faults occur in the operation process of the system and by means of the software system fault detection method, similar fault cases are found out through state switching sequences operated by software and corresponding repair measures are provided.

Description

technical field [0001] The invention relates to the technical field of software systems, in particular to a software system fault detection method based on dynamic description logic and case reasoning. Background technique [0002] With the improvement of software technology and the continuous expansion of software application fields, more complex technical systems need to be controlled by software. In today's software applications, it is necessary to pay more attention to the correctness, reliability, performance, privacy, usability, confidentiality and security of software systems and other trusted properties. The trusted software system proposed in the software field refers to a stable software system with fault tolerance. That is, in the case of system errors, the system can still provide correct services. If the fault-tolerant function is realized in the development stage of the system, the reliability of the system can be improved. In the process of realizing a trus...
