- Abstract:
- Web service (WS) is a fast growing technology. A set of WS is one of the best applications of multi-agent system, i.e. a WS is represented by an agent. This fact results in WS encapsulation and causes difficulty to track its internal behaviour. One solution of this problem is to use a notification system, where changes in WS are represented by a set of notification messages. The set of notification messages gives only static information about WS. If time 1 between notification messages is considered, then a web service dynamics can be described.
This article proposes an approach for estimating WS runtime and prediction of WS operation faults. Prediction of WS runtimes can optimize scheduling and support efficient use of grid resources. In our approach we propose to estimate expected WS runtime based on WS invocation parameters using case-based reasoning and prediction of WS operation faults using rule-based reasoning.
This article consists of two main parts. The first one includes introduction into reasoning and its two special types, namely case-based and a rule-based reasoning. In the second section, prediction of WS runtime is presented. In the third section, the diagnostics of web service operation faults is offered. - Keywords:
