Entity Resolution (ER) has been one of the bedrocks in the creation of information systems by ensuring ambiguous entities are identified and resolved by linking. One common design approach of traditional ER systems is to run in single-threaded mode, which makes the system prone to out-of-memory error when processing larger datasets. The Data…

This study seeks an affirmative answer to the question whether a knowledge-based approach to system of systems interoperation using semantic web standards and technologies can provide the centralized control of the capability for exchanging data and services lacking in a federation of systems. Given the need to collect and share real-time…

The education sector remains abuzz with cost-cutting expectations despite pressures to increase services. Automation of costly manual tasks could save funds for many of these institutions, specifically in data protection. The IT departments of schools and universities can take advantage of a proven cost-savings opportunity in data protection that…

In April, Asia officially ran out of Internet Protocol (IP) version 4 addresses--the computer equivalent of running out of telephone numbers. Over the next couple of years, the rest of the world will also run dry. Yet, unlike the Y2K bug that had some people convinced the sky would fall, this particular problem is generating little more than tired…

The use of Service Oriented Architectures, namely web services, has become a widely adopted method for transfer of data between systems across the Internet as well as the Enterprise. Adopting a similar approach to embedded devices is also starting to emerge as personal devices and sensor networks are becoming more common in the industry. This…

The need, use, benefit and potential of e-portfolios have been analysed and discussed by a substantial body of researchers in the education community. However, the development and implementation approaches of e-portfolios to date have faced with various challenges and limitations. This paper presents a new approach of an e-portfolio system design…

Current research in health care lacks a systematic investigation to identify and classify various sources of threats to information privacy when sharing health data. Identifying and classifying such threats would enable the development of effective information security risk monitoring and management policies. In this research I put the first step…

In October 2009, California Digital Library (CDL), where the author serves as manager of strategic and project planning, jumped into the world of social networking by joining Twitter. From Twitter, the CDL staff publish the content of their monthly newsletter, "CDLINFO News," and also additional content created by CDL programs and…

Information is everywhere and finding the best method to manage it is a problem that all types of organizations have to deal with. Schools use Student Information Systems (SIS) to manage Student Data, Financial Information, Development, Human Resources, Admission, Financial Aid, Enrollment, Scheduling, and Health Information. A survey of 107…

In this article we propose a novel e-learning system, dedicated strictly to knowledge assessment tasks. In its functioning it utilizes web-based technologies, but its design differs radically from currently popular e-learning solutions which rely mostly on thin-client architecture. Our research proved that such architecture, while well suited for…

Security incidents resulting from human error or subversive actions have caused major financial losses, reduced business productivity or efficiency, and threatened national security. Some research suggests that information system security frameworks lack emphasis on human involvement as a significant cause for security problems in a rapidly…

Targeted email attacks to enable computer network exploitation have become more prevalent, more insidious, and more widely documented in recent years. Beyond nuisance spam or phishing designed to trick users into revealing personal information, targeted malicious email (TME) facilitates computer network exploitation and the gathering of sensitive…

In this paper, we propose a conceptual and operational framework for process reengineering (PR) in higher education (HE) institutions. Using a case study aimed at streamlining exam scheduling and distribution in a distance learning (DL) unit, we outline a sequential and non-linear four-step framework designed to reengineer processes. The first two…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

Over the past several decades, millions of digital objects of significant scientific, economic, cultural, and historic value have been published and distributed to libraries and archives on removable media. Providing long-term access to these documents, media files, and software executables is an increasingly complex task because of dependencies…
