This paper introduces SmartCare, a project revolving around a smart environment especially built to enable aging in place. The paper describes the vision behind SmartCare as well as its translation into a deployed system. The physical incarnation of SmartCare is the SmartCare apartment, an actual apartment in a retirement community. We provide a description the technologies that are deployed in the...
This article leads the concept of data visualization into the huge amounts of news data, design and implements a system of News Data Visual System (NDVS). It is a news gathering, analysis, structured storage and visual analysis system. NDVS collects news data in the schedule time from seeds website by a web spider that written by java every day. The structured documents that processed and analyzed...
Human sensing is a notion of crowd-sourcing whereby ICT devices are utilized for data collection. Human Sensor Web (HSW) is a network of people who interact with their devices in order to forward their observations to a designated receiving server in the form of messages (such as SMS and USSD). It capitalizes on the accessibility of ICT tools (such as mobile phones) by non-experts to use them as sensory...
The growing complexity of embedded systems makes their behavior analysis a challenging task. In this context, tracing appears to be a promising solution as it provides relevant information about the system execution. However, trace management and analysis are hindered by the diversity of trace formats, the incompatibility of trace analysis methods, the problem of trace size and its storage as well...
In this paper we present a system that combines the cognitive and socio-cultural paradigms existent in the field of discourse analysis in order to analyze both narrations and conversations. The novelty of our approach is that existing applications are oriented on analyzing only one of these two types, an adaptation being necessary for the analysis of the other type.
Component-based development is widely used in large-scale software systems, which is focused on modularization and reusability. Each component has several related interfaces, which clearly describe the function, behavior and other relevant information. In addition, component interface also defines communications with other modules. Thus the interface defines all information of the component. The failure...
The broad adoption of diagnostic and analytical techniques in the field of archaeology, presents a unique opportunity for e-Science in the form of scientific explanation, drawing from methodologies aimed at recording, archiving, analyzing, and disseminating, rich data collections. This paper presents a needed stepping stone towards cyber-archaeology, creating synergy between information technology...
Action Science Explorer (ASE) is a tool designed to support users in rapidly generating readily consumable summaries of academic literature. It uses citation network visualization, ranking and filtering papers by network statistics, and automatic clustering and summarization techniques. We describe how early formative evaluations of ASE led to a mature system evaluation, consisting of an in-depth...
The Geospatial data has been used extensively in many scientific areas but a lot of issues arise for sharing and processing such large amount of data. The geospatial data is exposed most of the time using geospatial Web services, standardized by the Open Geospatial Consortium (OGC). In this paper we discuss solutions and approaches, based on the integration of OGC Web services into the Grid environment,...
Change impact analysis plays an immanent role in the maintenance and enhancement of software systems, especially for defect prevention. In our previous work we have developed approaches to detect logical dependencies among artifacts in repositories and calculated different metrics. But that is not enough, because in order to use change impact analysis a detailed process with guidelines on the one...
In our research cluster on transculturality many projects deal with georeferenced data. This paper offers an introduction to the new project GeoTwain that works on visualisation techniques for such data. Based on an analysis of the global telegraph network as an example of transcultural research using geo-referenced data, the paper derives user requirements by combining experiences gained from previous...
We propose a solution to the problem of exploring large, complex data sets in a (relational) database by a human user. In a nutshell, our proposed solution is to develop the tools to support data exploration and browsing in an organized manner. We introduce: (a) an organization of data around the idea of defining distances on data sets, to reflect the intuitive notion of data that is (closely) related...
The ambiguity of browser definition is the idea of this paper. Browser is not only used to access Internet pages, but actually it is a program that lets us look through a collection of data. Now, the questions are where the collection of data were stored and what kind of data supported by the browser. There are several kinds of browser, but we are focusing on two kinds of browser, hyperbolic and bifocal...
