Purpose Web services play vital role in the development of emerging technologies such as Cloud computing and Internet of Things. Although, there is a close relationship among the discovery, selection and composition tasks of Web services, research community has treated these challenges at individual level rather to focus on them collectively for developing efficient solution, which is the purpose of this work. This paper aims to propose an approach to integrate the service discovery, selection and composition of Semantic Web services on runtime basis. Design/methodology/approach The proposed approach defined as a quality of service (QoS)-aware approach is based on QoS model to perform discovery, selection and composition tasks at runtime to enhance the user satisfaction and quality guarantee by incorporating non-functional parameters such as response time and throughput with the Web services and user request. In this paper, the proposed approach is based on ontology for semantic description of Web services, which provides interoperability and automation in the Web services tasks. Findings This work proposed an integrated framework of Web service discovery, selection and composition which supports end user to search, select and compose the Web services at runtime using semantic description and non-functional requirements. The proposed approach is evaluated by various data sets from the Web Service Challenge 2009 (WSC-2009) to show the efficiency of this work. A use case scenario of Healthcare Information System is implemented using proposed work to demonstrate the usability and requirement the proposed approach. Originality/value The main contribution of this paper is to develop an integrated approach of Semantic Web services discovery, selection and composition by using the non-functional requirements.

In the last decade, selecting suitable web services based on users’ requirements has become one of the major subjects in the web service domain. Any research works have been done - either based on functional requirements, or focusing more on Quality of Service (QoS) - based selection. We believe that searching is not the only way to implement the selection. Selection could also be done by browsing, or by a combination of searching and browsing. In this thesis, we propose a browsing method based on the Scatter/Gather model, which helps users gain a better understanding of the QoS value distribution of the web services and locate their desired services. Because the Scatter/Gather model uses cluster analysis techniques and web service QoS data is best represented as a vector of intervals, or more generically a vector of symbolic data, we apply for symbolic clustering algorithm and implement different variations of the Scatter/Gather model. Through our experiments on both synthetic and real datasets, we identify the most efficient ( based on the processing time) and effective implementations.

The publication of Linked Data on the Web regarding several application domains leads to new problems related to Requirements Engineering, which needs to take into account aspects related to new ways of developing systems and delivering information integrated with the Web of Data. Tasks such as (functional and non-functional) requirements elicitation and ontology-based conceptual modeling can be applied to the development of systems that publish Linked Data, in order to obtain a better shared conceptualization (i.e., a domain ontology) of the published data. The use of vocabularies is an intrinsic activity when publishing or consuming Linked Data and their choice can be supported by the elicited requirements and domain ontology. However, it is important to assess the risk when choosing external vocabularies, as their use can lead to problems, such as misinterpretation of meanings due to poor documentation, connection timeouts due to infrastructure problems, etc. Thus, risk identification, modeling and analysis techniques can be employed, in order to identify risks and their impacts on stakeholder goals. In this work, we propose GRALD: Goals and Risks Analysis for Linked Data, an approach for modeling goals and risks for information systems for the Web of Data.

The article reveals the problem of implementing environmental environmental control in cities, where new centers of pollution, unauthorized landfills, etc. appear daily. Despite the large number of activities undertaken by environmental organizations, the problem remains open, because the main resource, the city dweller, is poorly involved. The authors indicate that often city dwellers do not receive timely information on the possible places for receiving special waste (batteries, glass containers, thermometers), or on environmental measures being taken, and also do not have the opportunity to quickly send an application for the elimination of the place of illegal garbage storage or illegal dumping. And despite the organization of waste collection points, various subbotniks, landscaping events, hot lines for receiving proposals from the population, as a rule, the primary operational task is not to realize – the availability of information in the field of environmental control of the urban environment. To solve this problem, the authors proposed to design and implement a web-based service for fixing and informing the administrative services and the city population about the environmental situation. The service will consist of a mobile application and a website. The main functional requirements for the web service were: the ability to photograph garbage objects; obtaining the location coordinates of garbage objects; sending data to the server without mandatory user registration; displaying the status of garbage objects on an interactive city map. The article presents the process of modeling the future web service using the notation of a unified modeling language. A use case diagram has been developed that describes the main roles of users who will work with this web service, as well as its functional requirements. In addition, the level of logical presentation of the service in the form of activity diagram is implemented. The physical representation of the web service is described through a deployment diagram.

The article is devoted to the issues of teaching high school students CSS animation (Cascading Style Sheets) in the framework of extracurricular activities using the gamification method. The current problems of teaching web programming at school are considered, its main components are highlighted: HTML page layout, programming on the client and server sides. The analysis of existing services and online games for teaching web layout is presented. As a result of the analysis of the traffic of the studied services, an increased interest of Internet users in web simulators, implemented using the principles of gamification, was revealed. However, today there are a limited number of such services, in addition, many topics of web programming and layout are still unrealized with the help of such web simulators.The article describes a completed project of developing a web simulator for teaching the basic properties of CSS animation. When designing a web simulator, the requirements for the implementation of game mechanics and dynamics were considered, which will make it possible to organize the educational process in a dynamic, exciting and visual way. The article describes the key features of the web simulator, its functional requirements, provides a rationale for the choice of topics and design of the web simulator, and considers the algorithm of its operation. The topics that are studied as a result of passing tasks in the web simulator are listed. The risks associated with the implementation of the web simulator in the educational process are described.The authors carried out an experiment on the basis of an additional education institution "KiberOne Programming School" among 10th grade students, the results of the experiment showed the effectiveness of using the developed web simulator in teaching CSS animation.

When we looked at the characteristics of document and Web content management in Chapter 3, we noted that there could be many limitations with how enterprises manage content published to Web sites. In Chapter 4, we demonstrated that subsystems exist within the IDCM framework to address these types of limitations. The importance of relevant and timely content cannot be understated. Its presence has a significant impact on the quality, effectiveness, and popularity of a Web site, with some observers (Chatelain & Yen, 2000) jesting that “content is the next frontier” on the Internet. If visitors to a site are not satisfied with its content, the “one click” factor applies — these visitors are one click away from moving from one Web site to another site. Depending on the nature of the Web site, the effectiveness of content might be measurable using a range of performance criteria. For example, transactional logs stored on Web servers may provide an indication of how much navigation is carried out within a site. There has also been a great deal of analysis of how the content may best be structured in an information architecture (Rosenfeld & Morville, 1998), and development of evaluation schemes that establish qualitative criteria for evaluation of various factors, such as how the functionality, design, authority, and validity of a site influence the substance of the content (Auer, 2002). In this chapter, we extend our discussion on the capabilities of IDCM systems to manage Web content, irrespective of whether the content is targeted for Internet or intranet sites. We review the functional requirements for a managed IDCM environment that provides cohesive end-to-end management of processes associated with the development and management of Web content. Our objectives are as follows: • Review the types of functionality offered by IDCM solutions for implementing management services over the Web content life-cycle. • Provide a checklist of functionality that provides a primer for organizations when considering their specific requirements for managing Web content.
