Mobile devices, such as smart phones, PDAs, or laptops are part of our everyday life. They became ubiquitous and pervasive. Their benefits are exploited in more and more scenarios and application domains. This paper presents an example of how mobile devices and their related applications may be successfully used by the bike fans. The issue is to provide an application for all types of bike users (e...
The ever increasing amount of content on the Internet has fostered many efforts seeking to leverage this potentially yottascale information source. Service systems using advanced data and text analytics techniques have been developed to perform knowledge gathering and information discovery over Web data. Information gathered from free and public sources on the Web is frequently integrated with enterprise...
The evolution of the World Wide Web has progressed from simple, classic Web pages with text and static images only to Web 2.0 pages with rich multimedia content, mashups and desktop-style applications. The cornerstone of Web 2.0 technologies is an API called XMLHttpRequest - an interface that allows network requests to be performed asynchronously without blocking the user interface of the Web browser...
The respond of traditional Web application to user interface is slow and wasting bandwidth, which bring user a lot of inconvenience, while the emergence of Ajax has changed this situation. Ajax can maintain data without refreshing the page, which greatly reduce the time of waiting for a large number of exchanged data for user. The advantages of both is fully demonstrated by the support which Struts2...
Recommender systems are used to suggest customized products to users. Most recommender algorithms create collaborative models by taking advantage of Web user profiles. In the last years, in the area of recommender systems, the Netflix contest has been very attractive for the researchers. However, many recent papers on recommender systems present results evaluated with the methodology used in the Netflix...
A virtual whiteboard is a common interface approach for supporting group processes. Built on the insights gained from previous studies, we built an application that is capable of supporting various creativity techniques based on a virtual whiteboard interface. A two-day pilot study indicated that collocated groups are able to effectively conduct collaborative creativity sessions with different creativity...
Scientific visualization is the process of transforming raw numeric data into a visual form, and is a key element of computational science. While many tools exist, they are unnecessarily difficult to use. This complexity increases time to insight and inhibits casual inquiry. The complexity derives from the need to support arbitrarily formatted data and many visualization algorithms. EnVision addresses...
Web applications are becoming increasingly popular. More and more types of multimedia data have been embedded into Web pages for providing abundant information and user interface. However, these complex Web pages could not be smoothly presented on devices without adequate functionalities or resource. An alternative approach is shifting tasks from resource-constrained device to surrogate with rich...
Personalized Web Search becomes nowadays a promising option in the field of Information Retrieval and search engines design by improving both output quality and user experience. In this paper, we present and evaluate the subsystem, which conducts the Advanced and Personalized search of PeRSSonal, a web-based mechanism for the retrieval, processing and presentation of articles and RSS feeds collected...
Cellular phones are widely used to access the Web. However, because of their small screens and poor interfaces, it is inconvenient to browse Web pages designed for desktop PCs. In this paper, we propose two novel functions that virtually extend a cellular phone's screen so that users can acquire more information from the small screens than the traditional Web browsing using cellular phones. The first...
"Work time management - WTM" is an application presenting an example of usage popular and open Web technologies accessible on the Internet. Web technologies used in the application are divided in two main groups. Client side technologies, this is cascading style sheets - CSS, script language - Javascript and asynchronous Javascript - AJAX with additional libraries like jQuery and Prototype,...
Grid computing is becoming more and more attractive for coordinating large-scale heterogeneous resource sharing and problem solving. Although Globus toolkit version 4 which is developed based on WSRF can successfully deal with the heterogeneity of resources and the diversity of applications, the current grid environments based on Globus toolkit version 4 have several limitations regarding dynamic...
In order to serve the on-line users who do shopping for 24 hours, the on-line shopping systems platform is more complicated than traditional one. Therefore, the user interface usability problems become a critical issue. Take the Yahoo!kimo shopping mall as a test platform. In this paper, the data collection method of thinking-aloud was adopted to record the participants. The video images and verbal...
Access control on form-based Web information systems has become one of the useful methods for implementing client systems in a service-oriented architecture. In particular, XForms language is being adopted in many systems as a description language for XML-based user interfaces and server interactions. In this paper, we propose an efficient algorithm for the evaluation of XPath-based access rules for...
In 2005, the design and future considerations of this hydrographic survey metadata data base (HSMDB) were presented at the Marine Technology Society Proceedings. This paper will provide an update. The HSMDB now offers a user interface to previously unavailable hydrographic survey data, data products and metadata conveniently and freely over the Internet. The product descriptive report images alone...
