Modern businesses like Amazon, Facebook, Google, eBay and many others have gained immense popularity, as they have been able to provide pertinent information based on user interactions with content. The prime mover for their success is the active usage of collective intelligence. The need for collective intelligence has increased with the stepping in of web 2.0. Applying it to improve user interactions...
Large amounts of valuable geosciences data have been collected due to the advances in digital earth technology. How to provide an efficient way through which researchers can easily retrieve desired data to facilitate data analysis and system modeling poses great challenges to the geosciences community. This paper presents a Geo-web services based system aimed to enhance geospatial data searching and...
We propose a framework for clustering and visualization of images of face carvings at archaeological sites. The pairwise similarities among face carvings are computed by performing Procrustes analysis on local facial features (eyes, nose, mouth, etc.). The distance between corresponding face features is computed using point distribution models; the final pairwise similarity is the weighted sum of...
The following topics are dealt with: software evolution; Word Wide Web; security of data; user interface; computer graphics; service-oriented system; software testing; data visualization; computer science education; and middleware.
Today's rich service offer in the World Wide Web increasingly requires the disclosure of personal user data. Service providers' appetite for personal user data, however, is accompanied by growing privacy implications for Internet users. Addressing this rising threat, privacy-enhancing technologies aim at aiding users in protecting their personal data. Even though effective privacy laws facilitate...
This current study explored the impact of individual differences in personality factors on interface interaction and learning performance in both an interactive visualization and a menu-driven web application. Participants were administered 6 psychometric measures designed to assess trait anxiety, locus of control, and other personality traits. Participants were then asked to complete 3 procedural...
Nagios is a popular network monitoring tool that can be used to monitor network services as well as data like processor load due to an SNMP interface. The visualization of status and alert messages can be conducted with a Web interface. Many plugins for the Nagios system are available that extend its features, also wrt. visualization of data. But so far, none of them allows users of PDAs like, e.g...
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...
T-Cube Web Interface is a generic tool to visualize and manipulate large scale multivariate time series datasets. The interface allows the user to execute complex queries quickly and to run various types of statistical tests on the loaded data. We show its utility in an important application scenario: real-time bio-surveillance system designed to support rapid detection and mitigation of bio-medical...
Much research has been devoted to collaborative tools for writing, group communication, reviewing, managing projects, and developing network infrastructures to support sharing activities. However the creation and display of foundational collaborative concepts that manage group work has not been paid significant attention. Information visualization potentially addresses the progression of distributed...
The TeraGrid user portal is a Web portal that aggregates and simplifies access to TeraGrid information and services for active TeraGrid users. The vision for the TeraGrid user portal is to become the resource that all TeraGrid users turn to for access, education, use and support of TeraGrid systems. The user portal is an operational activity of the TeraGrid project while also serving as a platform...
In traditional Web applications, user interface and interaction flows are controlled by software programs deployed on the server. These server side software programs are designed and implemented by software programmers, with no or very limited control provided to the end user.Although portal server technology and some JavaScript based solutions try to address this issue by offering some degree of...
In order to reduce the cost of information acquisition and improve the efficiency of information retrieval, it is very significant to integrate information visualization technology into information retrieval to help people better understand complex information space. This paper analyzes how to integrate the visualization techniques into Web information retrieval; and puts forward to an application...
Semantic event tracker (SET) is an interactive visualization tool for analyzing events (activities) in a three-dimensional environment. We model an event as an object that describes an action, its location, time, and relations to other objects. Real world event information is extracted from Internet sources, then stored and processed using Semantic Web technologies that enable us to discover semantic...
This paper describes the development of a 32-channel, 150 MHz bandwidth logic analyzer, implemented on an Altera Stratix II FPGA. This analyzer is remotely controlled through TCP/IP, allowing acquisition configuration and control, and data visualization via Internet, by means of a specific user interface.
TexPlorer is an integrated system for exploring and analyzing large amounts of text documents. The data processing modules of TexPlorer consist of named entity extraction, entity relation extraction, hierarchical clustering, and text summarization tools. Using a timeline tool, tree-view, table-view, and concept maps, TexPlorer provides an analytical interface for exploring a set of text documents...
The opening of Packery Channel in the Texas Gulf of Mexico region presented an opportunity to adapt an existing coastal observing system for scientific discovery, while addressing regulatory issues and decision support. Maintained and operated by the Shoreline Environmental Research Facility (SERF), specifically the objectives were current monitoring with data acquisition systems having a real-time...
Outdoor data acquisition systems (DAS) designed for long term monitoring of photovoltaic (PV) modules provide wide range of measurement conditions. Measured data contain modules' electrical parameters extracted from I-V curves and meteorological conditions occurring during measurements. Every year measurement volume of data systematically increases making analysis more complex and difficult. To cope...
