An Intelligent Web Service Composition and Resource-Optimization Method Using K-Means Clustering and Knapsack Algorithms

open access: yesMathematics, 2021
Service-oriented architecture (SOA) has emerged as a flexible software design style. SOA focuses on the development, use, and reuse of small, self-contained, independent blocks of code called web services that communicate over the network to perform a ...

The Executable Invocation Policy of Web Services Composition With Petri Net

open access: yesData Science Journal, 2015
The web service composition execution engine is a critical problem for web service composition. Based on Petri net and the analysis of structural relationships among web services, the invocation sequence of web service composition and its related ...

An Augmented Geospatial Service Web Based on QoS Constraints and Geospatial Service Semantic Relationships

open access: yesISPRS International Journal of Geo-Information, 2022
The service network is capable of addressing large-scale service composition. However, existing service network works still have several limitations. Prior knowledge, such as expert-defined service chains, is not incorporated into the service network ...

Validation of web service compositions

open access: yesIET Software, 2007
Web services support software architectures that can evolve dynamically. In particular, in this paper the focus is on architectures where services are composed (orchestrated) through a workflow described in the business process execution language (BPEL).

Web Service Composition via Supervisory Control Theory

open access: yesIEEE Access, 2018
We present a model for the service composition problem and relate it to the classical problem of supervisory control in discrete event systems. In particular, we show how the orchestrator in the first problem transparently maps to the controller in the ...

AN APPROACH TO DYNAMIC WEB SERVICE COMPOSITION

open access: yesInformation and Telecommunication Sciences, 2013
Today, changeable requirements to modern web-oriented services demand their fast development and constant reengineering. This is realized via dynamic composition of services, allowing to estimate changes of both functional and nonfunctional service ...

Service chain-based approach for Web service composition

open access: yesTongxin xuebao, 2007
A semantic match-based method was proposed for searching Web service chain by adopting the semantic matching algorithm for service profiles,which is based on the web services ontology and the domain-related ontology.By resorting to this method,a service ...

Location-Aware Web Service Composition Based on the Mixture Rank of Web Services and Web Service Requests

open access: yesComplexity, 2019
Web service composition is widely used to extend the function of web services. Different users have different requirements of QoSs (Quality of Services) making them face many problems.
