This paper aims to propose an approach for the self-adaptation of the Web composition called SAMIWA. The SAMIWA framework helps users during the search, invocation and composition of the appropriate Web service.

The authors’ approach allows expressing requirements by taking into account potential users’ context in addition to the functional one.

In this paper, the authors introduce a new context-aware approach that provides a dynamic adaptation of service compositions.

The author has implemented a Web application that enables selection and composition of the most appropriate composite service.

The purpose of this paper is to explore useful Semantic Web technologies and ontology-based applications for digital libraries. It also investigates the perceptions of university librarians and academicians in Pakistan about Semantic Web technologies and their use in digital libraries.

An exploratory research design based on Delphi research strategy was conducted to answer the research questions. Interviews were conducted with a purposive sample of 50 key informants including university librarians and academicians to explore their perceptions about Semantic Web technologies and their use in digital libraries. Thematic analysis of interview data was conducted to obtain results.

The results of this paper showed that DuraCloud, Semantic information mashup, OntoEdit and resource description framework (RDF) are the various Semantic Web applications which are useful for digital libraries to develop semantic relationships among digital contents and increase their accessibility in the web environment. Findings revealed that Semantic Web provides precise results and meets user information needs in an effective way. Results also showed that next-generation digital libraries use context-awareness technology, intelligent agent software and detecting sensors to analyze user information needs and provide dynamic information services. This paper recommended that librarians should embrace the use of emerging web technologies in libraries and offer library services through the medium of the web.

This paper envisaged the future of digital library services and Semantic Web applications that can be used to re-structure metadata of digital library. This paper has practical implications for librarians to consider the useful applications of Semantic Web for digital library and enhance the interoperability of metadata among heterogeneous information systems. Practically, results obtained from this paper are highly useful for library schools and LIS teachers to up-date their curriculum by incorporating new contents related to web languages and Semantic Web applications for digital libraries.

This paper identifies various Semantic Web applications which are useful for developing Semantic Digital Libraries.

This paper seeks to provide an insight into the implementation of some of the innovative Web 2.0 applications at Jaypee University of Information Technology with the aim of exploring the expectations of the users and their awareness and usage of such applications.

The study was undertaken at the Learning Resource Centre (LRC), Jaypee University of Information Technology (JUIT), Solan, Himachal Pradesh, India. The LRC at JUIT serves its patrons in supplementing their research needs while creating an ambience for teaching, learning and research. The emergence of digital technologies and information and communications technology (ICT) tools in libraries has encouraged the implementation of a wide range of applications, such as digital libraries, video on demand, reference services and database services into library services. The advent of next‐generation web technologies, known as Web 2.0 applications, has prompted a number of other pertinent services to be implemented to enhance the information literacy skills of the existing services. A survey method was used to understand the basic awareness and expectations of library users, and the usability of resources.

The LRC has made a number of provisions to adopt some Web 2.0 applications in its library services to create information literacy. The users of the JUIT library still lack awareness about various Web 2.0 applications necessary for teaching and learning.

The paper suggests that Web 2.0 applications can be used effectively to create information literacy amongst users. Library and information science (LIS) educators should take advantage of advances in the field of ICT and consider the learning preferences of information natives as well as information immigrants. Web 2.0 supports a constructivist approach to information awareness tools, and has great potential to socialise learning and information delivery to a greater extent. Web 2.0 technologies should be implemented as a medium of information communication, taking into account the pedagogical perspectives.

The case study is a practical application at the Jaypee University of Information Technology. The LRC has implemented some Web 2.0 applications in the Library. The study was undertaken at the university to understand the basic awareness of Web 2.0 and to create information literacy amongst users through it.

This paper aims to explore Web 2.0 technologies usage and trends in the top 100 US academic libraries as exemplified through the academic library websites.

The top 100 universities were selected from the US News & World Report's (USNWR) 2013 ranked list's top 100 of the best colleges in the USA. Content analysis was used in terms of quantitative approach. A checklist was developed as the main research instrument based on other checklists and questionnaires. Each of the selected university library websites was visited within a period of two weeks to explore implementation and usage of web tools, including SNS, blog, RSS, wikis, podcast/vodcast, and social bookmarking/tagging.

All 100 academic libraries had a social media presence on Facebook and Twitter, making SNS the most widely applied Web 2.0 tool. The wiki was the least applied Web 2.0 technology, with a 34 percent participation rate. Blog was the second most popular tool with a 99 percent participation rate, followed by RSS and IM/Chat with 97 percent and 91 percent respectively. The vodcast and podcast had 47 percent and 46 percent participation rates respectively, while social bookmarking/tagging were also used by 39 percent of the academic libraries.

This study is completely based on publicly available data regarding usage of Web 2.0 applications. Web 2.0 tools used on library intranets were not analyzed for this study. Outcomes suggest that academic libraries are increasingly using Web 2.0 applications to promote themselves, enhance library services, and highlight resources to patrons.

This is the first research that draws an overall picture of the usage and trends of Web 2.0 applications in the top 100 US academic libraries. This study demonstrates some noticeable patterns regarding usage, trends, and adoption which are relevant to how Web 2.0 applications are perceived and used within academic libraries. The study provides academic libraries with helpful information to better meet their user needs by effectively applying Web 2.0. Additionally, library managers, librarians and other libraries may also find this research beneficial as they plan to deploy Web 2.0.

This study aims to investigate the application of Web 2.0 technologies in the libraries of the top 100 universities in the world to provide a model for Web 2.0 application in academic library websites.

Data were collected from the universities’ library websites for three months based on a Web 2.0 checklist. The list of universities was extracted from Webometrics Ranking of World Universities in 2015.

The research shows the priorities of these universities in their use of Web 2.0 tools include social networks and mashups at the most (94.5 per cent), followed by RSS (91.2 per cent) and social tagging (82.4 per cent) and other tools with lower priorities. Moreover, it revealed the most common applications of these tools in the mentioned websites followed by their objective evidences in different libraries. The results indicate that the total Web 2.0 application in the libraries of the top 100 universities was below average (40.23 per cent). Finally, the model for Web 2.0 application in academic library websites was designed.

The focus of this study is on the value and application of each tool in the websites and demonstrate a clear model to apply in other library websites. The model for Web 2.0 technologies application in academic library websites has not been designed and pictured before.

This paper aims to investigate 152 pre-service and in-service school teachers’ perceptions toward Web 2.0 applications and their usage in the United Arab Emirates (UAE). A five-point Likert scale questionnaire was used. The data were analyzed quantitatively using descriptive statistics and independent sample t-tests. The descriptive statistics were used to identify teachers’ perceptions toward Web 2.0 applications and their usage. The t-test was used to investigate the differences in perceptions between groups due to gender, and experience using computers and the Internet. The results showed that teachers have high perception toward Web 2.0 tools and services, but the extent to which they use Web 2.0 applications is somehow moderate. Moreover, no statistically significant differences in perception toward Web 2.0 were detected due to gender or experience using computers and the internet. Recommendations and suggestions for improving Web 2.0 integration into teaching and learning are proposed.

This study adopted the quantitative research approach using a questionnaire for data collection. The questionnaire was designed to investigate teachers’ perceptions of using Web 2.0 applications as a method for teaching and learning purposes.

The results showed high self-perception of teachers toward Web 2.0 and their use for improving students’ performance, which can be attributed to their awareness of Web 2.0 importance and benefit in education. On the other hand, results indicated a low use of most of Web 2.0 tools such as microblogging, audio file sharing, photo sharing and content developing. Again, these findings can be attributed to the lack of professional training on using Web 2.0. In addition, the results did not show significant differences between male and female teachers in using Web 2.0 applications with the exception of two items. Neither did the results show any significant differences between teachers who are beginners in using computers and the internet and teachers who are advanced. This could be because beginner users of computers and the internet have the same motivation as the advances users pertaining to teaching.

There must be an extensive training for teachers on how to use Web 2.0 tools to enhance their teaching. Infrastructure for the internet should be available so that teachers can use Web 2.0 without worrying about the technology infrastructure at their schools. More research studies should be conducted regarding the use of Web 2.0 by teachers and students alike. A qualitative and quantitative method of data collection should be used when investigating different aspects of Web 2.0. A comparison between K-12 teachers and higher education faculty members should be conducted pertaining to the use of Web 2.0 for education. A comparison study between pre-service and in-service teachers should be conducted to investigate Web 2.0 tools for educational and personal purposes.

The purpose of this paper is to establish common metrics for web-based mapping applications to facilitate user decision making and enhance information providers’ product design.

The metrics were developed from a combination of literature review and case studies. From the literature review, the authors identified three major areas of assessment for web-based mapping applications. The authors then studied six online applications to refine the metrics.

The results suggest that web-based mapping applications can be evaluated from three major aspects: data content, geographic information systems (GIS) functionality and usability. The authors have developed detailed measures for each factor through the evaluation of the six applications.

The metrics developed from this study could be used as a standard for online spatial information users to choose appropriate products according to their needs. It can also provide valuable information for data providers to improve their products.

To the best of the authors’ knowledge, this is the first study that has systematically examined web-based mapping applications in academic libraries. Results from this study could be a valuable tool for librarians as well as general information users without background of GIS and usability to evaluate online mapping resources.

The Internet is changing the way businesses operate today. Firms are using the Web for procurement, to find trading partners, and to link existing applications to other applications. Web services are rapidly becoming the enabling technology of today’s e‐business, and e‐commerce systems. We are having a massive impact on the way businesses think about designing, developing, and deploying Web‐based applications. Web services may be an evolutionary step in designing distributed applications, however, they are not without problems. There are issues relating to security, transactions and scalability that need to be addressed. This paper addresses security concerns in Web services and the role of technology trust.

Internet users and Web-based applications continue to grow every day. The response time on a Web application really determines the convenience of its users. Caching Web content is one strategy that can be used to speed up response time. This strategy is divided into three main techniques, namely, Web caching, Web prefetching and application-level caching. The purpose of this paper is to put forward a literature review of caching strategy research that can be used in Web-based applications.

The methods used in this paper were as follows: determined the review method, conducted a review process, pros and cons analysis and explained conclusions. The review method is carried out by searching literature from leading journals and conferences. The first search process starts by determining keywords related to caching strategies. To limit the latest literature in accordance with current developments in website technology, search results are limited to the past 10 years, in English only and related to computer science only.

Note in advance that Web caching and Web prefetching are slightly overlapping techniques because they have the same goal of reducing latency on the user’s side. But actually, the two techniques are motivated by different basic mechanisms. Web caching uses the basic mechanism of cache replacement or the algorithm to change cache objects in memory when the cache capacity is full, whereas Web prefetching uses the basic mechanism of predicting cache objects that can be accessed in the future. This paper also contributes practical guidelines for choosing the appropriate caching strategy for Web-based applications.

This paper conducts a state-of-the art review of caching strategies that can be used in Web applications. Exclusively, this paper presents taxonomy, pros and cons of selected research and discusses data sets that are often used in caching strategy research. This paper also provides another contribution, namely, practical instructions for Web developers to decide the caching strategy.

The purpose of this research is to facilitate the full potential of the web for the people with disabilities. People with disabilities may fail to make full use of the potentials offered by the web even if they have the right hardware (computer and assistive technologies) as well as access to the internet because of the lack of accessibility.

This research outlines the guidelines that provide the foundation for building an accessibility-aware framework approach, where people with disabilities can access most of the electronic contents based on their disability levels.

The framework helps web engineers in developing accessible web pages for all types of users. Disability profile examples (blindness, low vision, deafness and hard of hearing) were taken to determine the performance of the framework approach.

The validation and testing was carried out on the Sultan Qaboos University website. The framework approach could be further validated by performing the tests on various other public and private websites.

The guidelines can be used as a road map to overcome accessibility challenges during any web application development life cycle. A proper testing and evaluation is carried out on the framework to test its usability.

Although people with disabilities are perhaps the segment of society which are expected to gain the most from these technologies, they are facing barriers to access the contents of the web because of the way it is presented. This proposed framework could assist all the people with the disability of blindness and hearing impairment to have a better experience with the internet, making the technology more beneficial and usable to them. In the future, this approach can be extended for the people with other disabilities.

This research provides a pioneering concept for accessibility-aware framework approach. This approach could be utilized for developing accessible web applications and electronic services for people with disabilities. The proposed framework can be used as a road map to overcome accessibility challenges during any web application development life cycle.
