The big volume of candidate Web services and their differences make it hard for developers to discover a set of appropriate ones for mashup creation. Thus, recommending suitable services is a vital problem. Service recommendation methods should ...

Personalized travel mashups aim to assist users in making decision i.e what places to visit. To facilitate human decisions with credible suggestions, these systems should have the ability to generate corresponding explanations while making ...

The evolution analysis on Web service ecosystems has become a critical problem as the frequency of service changes on the Internet increases rapidly. Developers need to understand these evolution patterns to assist in their decision-...

• Identify data quality issues in ProgrammableWeb dataset.
• Correct evolution ...

Since the emergence of web 2.0, data started floating all over the web, through online and offline applications, and across all application domains. Web data (semi-structured data loaded through web browsers and applications ...

The advent of Service-Oriented Architecture (SOA) has brought a fundamental shift in the way in which distributed applications are implemented. An overwhelming number of Web-based services (e.g., APIs and Mashups) have leveraged this shift and furthered ...

• Flexible data acquisition system for mashup applications.
• Capturing the user’s ...

Nowadays, mashups applications are growing in popularity. They are accessible by cross-device applications, supporting multiple forms of interaction in cloud environments. In general, mashups manage a huge amount of heterogeneous data ...

Current scenarios for app development are characterized by rich resources that often overwhelm the final users, especially in mobile app usage situations. It is therefore important to define design methods that enable dynamic filtering of the ...

The proliferation of web-accessible sensors and actuators provided by smart things and mobile devices has led to a distinct class of WoT-applications. These are data-driven and situational as they build on the analytical processing of data streams from ...

Any upcoming industrial revolution will rely on the ability to harness software as the nervous system of future production environments. This paper proposes an app ecosystem as the potential key enabler of industry digitization and argues for the need ...

The EFESTO platform allows the creation of interactive workspaces supporting end users in the exploration and seamless composition of heterogeneous data sources. By means of a visual paradigm implemented within a Web composition environment, the end ...

Virtual Research Environments (VREs) are distributed and dynamic software environments that foster the collaboration of people from different disciplines by supporting the accomplishment of complex research tasks. VREs lack efficient and effective ...

We address the problem of component discovery in composition environments.A general method for component recommendation is presented.Component recommendation is based on structural analysis of compositions.A graph-based component recommender algorithm ...

Web-based geographic applications are continuously evolving and are becoming increasingly widespread. Actually, many Web-based geographic applications have been developed in various domains, such as tourism, education, surveillance and military. However,...

This paper proposes a new perspective on the problem of data integration on the Web: the one of the Surface Web. It introduces the concept of UI-oriented computing as a computing paradigm whose core ingredient are the user interfaces that build up the ...

In recent years, models, composition paradigms, and tools for mashup development have been proposed to support the integration of information sources, services and APIs available on the Web. The challenge is to provide a gate to a “programmable Web,” ...

Querying large data graphs has brought the attention of the research community. Many solutions were proposed, such as Oracle Semantic Technologies, Virtuoso, RDF3X, and C-Store, among others. Although such approaches have shown good performance in ...

With this article, we give an answer to one of the open problems of mashup development that users may face when operating a model-driven mashup tool, namely the lack of modeling expertise. Although commonly considered simple applications, mashups can ...

Context: The emergence of the long-tail in the market of software applications is shifting the role of end-users from mere consumers to becoming developers of applications addressing their unique, personal, and transient needs. On the Web, a popular ...

Despite the common claim by mashup platforms that they enable end-users to develop their own software, in practice end-users still don't develop their own mashups, as the highly technical or inexistent user bases of today's mashup platforms testify. The ...

The last decade has seen the evolution of web APIs (Application Programming Interfaces) and open data initiatives promoted by governments. This has encouraged develop- ers to build Mashups, web applications that integrate data from multiple servers. ...
