Quality In Use

World Wide Web software development is a challenge. The need to provide appealing and attractive user interfaces is combined with the fact that the World Wide Web is not merely an information transfer tool anymore. The capacity to offer additional services plays an important role. The World Wide Web makes these services available to a greater number of individuals who have different characteristics, knowledge and profiles. The World Wide Web demands quick development with high quality level. This chapter makes an important contribution in the field of software product characterization for the World Wide Web, proposing a quality model that focuses on quality in use or usability. Said quality model, which has been partially tested on real users through several experiments, is based on international standards and ergonomic criteria. The model has proved useful for organizing and applying the experience available in the development of user interfaces for Web applications and has improved noticeably its final quality in use.

With the ubiquitous availability of browsers and internet access, the last few years have seen a tremendous growth in the number of applications being developed on the world wide web (WWW). Models for analyzing and designing these applications are only just beginning to emerge. In this work, we propose a 3-dimensional classification space for WWW applications, consisting of a degree of structure of pages dimension, a degree of support for interrelated events dimension and a location of processing dimension. Next, we propose usability design metrics for WWW applications along the structure of pages dimension. To measure these ,we propose CMU-WEB: a conceptual model that can be used to design WWW applications, such that its schemas provide values for the design metrics. This work represents the first effort, to the best of our knowledge, to provide a conceptual model that measures quantifiable metrics that can be used for the design of more usable web applications, and that can also be used to compare the usability of existing web applications, without empirical testing.

Analytical Result

The increased dependency on the World Wide Web by both laboratories and their customers has led LIMS developers to take advantage of thin-client web applications that provide both remote data entry and manipulation, along with remote reporting functionality. Use of an LIMS through a web browser allows a person to interact with a distant application, providing both remote administration and real-time analytical result delivery from virtually anywhere in the world. While there are many benefits of web-based LIMS applications, some concern must be given to these new methods of system architecture before justifying them as a suitable replacement for their traditional client-server systems. Developers and consumers alike must consider the security aspects of introducing a wide area network capable system into a production environment, as well as the concerns of data integrity and usability.

Uniform Solution

Accessing the Web from mobile devices is a popular practice. Trends show that the mobile space is becoming the method through which many consumers access content – both through native and web applications. These applications have expanded the browsing experience, but have also complicated the development process. A need exists for a simple, uniform solution which HTML5 is attempting to address. HTML is a mark-up language, now on its fifth edition, used for structuring and presenting content on the World Wide Web. Because of the large increase in users of mobile devices, internet access on these devices is widely used. The creation of web sites, web documents, and applications are done with HTML5, as it is compatible with both PC and mobile device browsers. However, with its lengthy development process, it is not yet apparent if HTML5 can incorporate the demands of developers in a changing environment. This paper provides an overview of the use of HTML5 in structuring and presenting content on the World Wide Web and compatibility issues on mobile browsers, key features, tool’s, and the advantages and disadvantages on the mobile web devices as well as the state of the mobile web.

High Level

The evolution of the World Wide Web from hypermedia information repositories to web applications such as social networking, wikis or blogs has introduced a new paradigm where users are no longer passive web consumers. Instead, users have become active con- tributors to web applications, so introducing a high level of dynamism in their behavior. Moreover, this trend is even expected to rise in the incoming Web. As a consequence, there is a need to develop new software tools that consider user dynamism in an appropiate and accurate way when generating dynamic workload for evaluating the performance of the current and incoming web. This paper presents a new testbed with the ability of defining and generating web dy- namic workload for e-commerce. For this purpose, we integrated a dynamic workload generator (GUERNICA) with a widely used benchmark for e-commerce (TPC-W).

The Impact

We quantify the propagation and absorption of large-scale publicly available news articles from the World Wide Web to financial markets. To extract publicly available information, we use the news archives from the Common Crawl, a non-profit organization that crawls a large part of the web. We develop a processing pipeline to identify news articles associated with the constituent companies in the S&P 500 index, an equity market index that measures the stock performance of US companies. Using machine learning techniques, we extract sentiment scores from the Common Crawl News data and employ tools from information theory to quantify the information transfer from public news articles to the US stock market. Furthermore, we analyse and quantify the economic significance of the news-based information with a simple sentiment-based portfolio trading strategy. Our findings provide support for that information in publicly available news on the World Wide Web has a statistically and economically significant impact on events in financial markets.

Questionnaire Method

Nowadays, the Internet, i.e. its leading services like the World Wide Web are unavoidable in communications, providing services and information sharing. Websites and a variety of Internet pages that make up the World Wide Web are the primary user interfaces for online business, providing information and promotional activities on the Internet. The rapid and progressive development of this medium has led to the fact that there is almost no maritime education institution without its own website, or at least a web page. The quality and success of the presentation via the Internet and the development of websites in a way to suit users’ needs still remain a problem, not only for designers and managers but also for owners, representing an incentive for the analysis and research in the field of maritime colleges. In evaluating user interfaces, including websites, different approaches and methods are used where the usability, due to its widespread use, is most often considered as the main factor of quality. In this paper, usability factors of websites are analyzed using the questionnaire method and available online tools for 20 maritime universities worldwide and the obtained results are presented as well as recommendations for further researches.
