Log-based mining techniques applied to Web service composition reengineering

Abstract

There is no doubt that SOA and BPM will continue to evolve dependently for the next ten years. Preparing common research infrastructures will require most important efforts of web service community researchers. Web services composition is becoming more and more chaotic, involving numerous interacting ad-hoc services through huge business processes. Analysing and Reengineering of complex Web Service Compositions will enable them to be well understood, controlled, and redesigned. Our contribution to this problem is a patterns mining algorithm which is based on a statistical technique to discover patterns from execution log. Our approach is characterised by a "local" patterns discovery that allows to cover partial results through a dynamic programming algorithm. Those local discovered patterns are then composed iteratively until discovering the Composite Web Service. The analysis of the disparities between the discovered model and the initial ad-hoc CS model (delta-analysis) enables initial design gaps to be detected and thus the Web service composition to be re-engineered.

Recommendation for Web Service Composition by Mining Usage Logs

“…The concept of application of data mining is explored in [4], recommends a set of applications that can leverage problems concerned with the planning, development and maintenance of Web services and their compositions. [14] Presents a similar approach of applying Web service log-based analysis and process mining techniques in order to provide a mean to ensure a correct and reliable Web services modelling and execution. They also present the issues and challenges in collecting execution logs of service invocation.…”

Monitoring Information Quality Within Web Service Composition and Execution

“…All these information should be stored in the service log (Flow 9). Although there are approaches to specify log formats [7], current approaches such as the Common Log Format [9] and Combined Log Format of W3C are not sufficient for our approach as they are not directly able to represent the required information. Therefore, we propose a practical oriented log file.…”

Towards Proactive Web Service Adaptation

“…In software applications, logging refers to the recording of activities [15,6]. Throughout the service composition course, logging can be conducted at three different levels, which are an operational level, an interaction level and a workflow level.…”
