Accurate service tags recommendation plays a crucial role in classifying, searching, managing, composing, and expanding services. However, many service tags recommendation studies fail to consider real-world scenarios, greatly limiting their ...

Predicting Quality of Service (QoS) is an essential task in Service Oriented Computing (SOC). In service selection, choosing the right services is a crucial step to achieve high system stability and user satisfaction. Considerable research has ...

The large increase in the number of available Web services makes the selection of suitable services a big challenge. Several methods have been developed to predict the Quality of Service (QoS) values in order to solve the service selection ...

A web service is a software interface that describes a collection of operations that can be accessed over the Internet using standard protocols. Though web services have significant features, centralized UDDI architecture is one of the most ...

The cyber-physical system is a security-embedded intelligent system that integrates and organizes physical resources to offer effective and comfortable services for humans. Web service discovery is a significant challenge due to the increased rise ...

Modern software development paradigms, including Service-Oriented Architecture (SOA), tend to make use of available services e.g., web service Application Programming Interfaces (APIs) to generate new software. Thus, for the further advancement ...

We introduce OpenAPI Query Language 2 (OAQL2), an SQL-like language for querying OpenAPI documents. OpenAPI is a standard format for the description of REST services, based on JSON (or YAML). A Web service capable of executing OAQL2 ...

Numerous web services with the same function but different service qualities are constantly emerging on the network. Optimizing web service composition based on multiple candidate services sets an urgent problem in the service composition ...

With the advent of Web service technologies, the number of services published on the cloud is increasing rapidly. The quality of service (QoS) becomes a crucial criterion for selecting services from a massive pool of candidates. ...

In recent years, discovering appropriate web services has become increasingly difficult as the number of services has grown rapidly. With the goal of improving discovery performance through accurate text matching, this study developed ...

How to effectively predict missing QoS has become a fundamental research issue for service-oriented downstream tasks. However, most QoS prediction approaches omit high-order implicit invocation correlations and collaborative relationships among ...

Service-Oriented Architecture is a technology for designing software systems. Upon using this architecture, new challenges appeared for software testing in which unit testing can be viewed as the most essential and basic testing procedure. Many ...

This paper reports on the development of a Web platform to host the Mizar Mathematical Library (MML). In recent years, the size of formalized mathematical libraries has been drastically increasing, and this has led to a growing demand for tools ...

In order to better perform fault diagnosis on web services and help users to accurately detect service faults, this paper proposes a web service fault diagnosis model based on anomaly detection (ADWSFD). At present, the outlier detection ...

In 2021, more than 5.5 million new devices will be connected to the Internet of things every day. The discovery and access of IoT sensors are difficult to adapt to the growth rate of machines. Especially for non-smart IoT sensors, due to their ...

• The web service anti-pattern prediction model developed using Weighted Extreme Learning Machine algorithm (WELM) provides better performance compared to the ...

‘Anti-Pattern’ is a term often used by software engineers and practitioners nowadays. An anti-pattern is a supplement of the design pattern. Similar to design patterns, an anti-pattern is a template and a repeatable way of solving a ...
