Abstract. A central component of the web-based map application AustrianVineyards.com is the communication of the climatic conditions prevailing in the individual wine-growing regions. To accomplish this, it is necessary to obtain the relevant data and process it so that it can be converted into high-quality visualisations. Therefore, the goal is to develop a climate communication tool that is as flexible as possible, so that it is possible to display several meteorological parameters. Moreover, this visualisation should be appealing to experts as well as to laypersons. This paper shows how the data preparation and visualisation is managed so that these demands can be met. The result of the workflow are versatile climate and weather charts that are easy to interpret thanks to the inclusion of historical data. Furthermore, geocommunicative aspects are a central part of the concept through their assignment to wine origins from AustrianVineyards.com and visual properties that make the diagrams comparable with one another.

<p><strong>Abstract.</strong> In this article, we present a method for visualizing multi-dimensional spatio-temporal data in an interactive web-based geovisualization. Our case study focuses on publicly available weather data in Germany. After processing the data with Python and desktop GIS, we integrated the data as web services in a browser-based application. This application displays several weather parameters with different types of visualisations, such as static maps, animated maps and charts. The usability of the web-based geovisualization was evaluated with a free-examination and a goal-directed task, using eye-tracking analysis. The evaluation focused on the question how people use static maps, animated maps and charts, dependent on different tasks. The results suggest that visualization elements such as animated maps, static maps and charts are particularly useful for certain types of tasks, and that more answering time correlates with less accurate answers.</p>

One of the solutions to the problem of spatio-temporal data anisotropy is the use of a multilevel system of digital twins based on the corresponding industry models and the updated archive data base. The application of this approach has successfully proved itself in information systems for monitoring the parameters of the geomagnetic field and its variations, providing spatio-temporal interpolation of geomagnetic data with an accuracy of 0.81 nT in magnetically quiet periods. At the same time, the problem of information interaction between the levels of the system of digital twins remained unresolved, which is greatly aggravated by the constantly growing volume of data and their heterogeneous nature. The paper proposes a solution to the indicated problem by means of a formalized mechanism for packaging space-time information, in which the identification of data sources is performed on the basis of a hierarchical binary tokenization system. In addition, the proposed software implementation of such an approach is considered, a distinctive feature of which is the combination of traditional clientserver and innovative serverless architectures to implement a highly loaded reactive web application for working with analyzed data. The main stages of the implementation of information interaction are highlighted and programmatically formalized - from obtaining initial information from its sources to verifying data, analyzing them, processing and forming the output information flow of the system. The results of the computational experiments carried out on the example of the problem of monitoring the parameters of the Earth's magnetic field and its variations confirmed the effectiveness of the proposed solutions, expressed both in increasing the reactivity of web-based applications and in increasing the computational speed of formation and filling of information storages that aggregate information from distributed heterogeneous sources.

The rapid establishment of third generation distance learning environments, the so-called Web-based or tele-teaching environments, brought some problems with it. The main means for the delivery of the new educational approach is the World Wide Web, and there are some good reasons for it: It is easily accessible by many groups of learners. It supports multiple representations of educational material and various ways of storing and structuring this information. It is powerful and easy to use as a publishing medium. Additionally, it has been widely accepted that the hyper-medial structure of the Web can support learning. Some researchers characterize the Web as an active learning environment that supports creativity. In addition to this, the Web encourages exploration of knowledge and browsing, behaviors that are strongly related to learning. The associative organization of information in the Web is similar to that of human memory, and the process of information retrieval from the Web presents similarities to human cognitive activities (Tselios, Avouris, Dimitracopoulou, & Daskalaki, 2001). However, a hyper-medial space, like the Web, cannot be considered, only by these features, as an effective tutoring environment. It is rather more appropriate to think of the Web as a powerful tool that can support learning, if used in an appropriate way. This is because learning is a process (Duchastel, 2001) that depends on other features, such as learner’s motivation, previous experience and learning strategies that the individual has been supported to develop, and so forth. Effectiveness of any educational environment cannot be considered independently of these aspects.

At present, the web-based collaborative learning is the main form of long-distance learning and it has been widely used in the distance learning domain. However, the main body-intelligence degree of the existing Web learning system is low; the existing system lacks to the support of the personal study, which has hindered the individual skill of the users. According to the question that exists in the collaborative Learning, I constructed the intelligent agent model of collaborative Learning which is composed of main control program, student proxy, teaching proxy and the information proxy based on the intelligent agent technology which belongs to the domain of Artificial Intelligence and I discussed emphatically how to effectively realize the personal study by using the machine learning and the data mining method. It can cause the web-based cooperative learning developing along the direction of intelligent and personal

Web-based applications has turn out to be very prevalent due to the ubiquity of web browsers to deliver service oriented application on-demand to diverse client over the Internet and cross site scripting (XSS) attack is a foremost security risk that has continuously ravage the web applications over the years. This paper critically examines the concept of XSS and some recent approaches for detecting and preventing XSS attacks in terms of architectural framework, algorithm used, solution location, and so on. The techniques were analysed and results showed that most of the available recognition and avoidance solutions to XSS attacks are more on the client end than the server end because of the peculiar nature of web application vulnerability and they also lack support for self-learning ability in order to detect new XSS attacks. Few researchers as cited in this paper inculcated the self-learning ability to detect and prevent XSS attacks in their design architecture using artificial neural networks and soft computing approach; a lot of improvement is still needed to effectively and efficiently handle the web application security menace as recommended.

In the Web-based learning era, the possibility to use the online network for learning activities, studies and research has brought about a revolution in the educational processes and the emergence of a new culture characterized by the idea that knowledge is not closed and defined, but open and accessible to all. Within a perspective in which knowledge is generated by the interaction of the individual with the environment, the socio-constructivist approach paved the way to new theoretical frameworks that, starting from the social dimension of learning, acknowledge and embrace the biological aspects of learning processes, thus offering interesting reflections on the web-learning phenomenon. Stemming from these assumptions, LiveCampus was created; a social learning environment aimed at fostering a synergistic integration between the dimensions of formal and informal knowledge.

Most people are more or less related to the web by participating in a kind of social networking site. Semantic Web technology plays a crucial role in these sites as they contain an enormous amount of data about ‎persons, pages, events, places, corporations, etc. This research is a Semantic Web application designed to create a new ‎semantic social community called Socialpedia. It links the already existing social public information to the newly ‎public ones. This information is linked with different information on the web to construct a new immense ‎data container. The resulting data container can be processed using a variety of Semantic Web techniques to produce ‎machine-understandable content. This content shows the promise of using integrated data to improve Web search and ‎Web-scale data analysis, unlike conventional search engines or social ones. This community involves obtaining data ‎from traditional users known as contributors or participants, linking data from existing social networks, extracting ‎structured data in triples using predefined ontologies, and finally querying and inferring such data to obtain ‎meaningful pieces of information. Socailpedia supports all popular functionalities of social networking websites ‎besides the enhanced features of the Semantic Web, providing advanced semantic search that acts as a semantic ‎search engine.

Many businesses obtain feedback by surveying customers and business partners. Increasingly, these surveys are conducted via the Web. This chapter reviews briefly literature regarding Web-based surveys and describes a software architecture for a Web-based survey system. The architecture for the survey system is based on three-tiers comprised of a Web server, Web application server, and database server. The Web application server hosts the application modules that display and process the surveys. The application software consists of packages for establishing connections to the database and for reading static and dynamic data from the database. The processed surveys are written to the database with the survey responses. This system allows for anonymous survey responses and maintains user confidentiality. At the University of Wisconsin-Parkside, we have implemented this Web-based survey system, and used it to conduct three different surveys. This survey system is easily extensible to new surveys, and is used for instructional purposes to teach server-side programming. In this chapter, we discuss the key ideas behind the design and implementation of the extensible survey system, and provide results on its application.
