Generalized Evidential Processing in Multiple Simultaneous Threat Detection in UNIX

In this paper, a hybrid identity fusion model at decision level is proposed for Simultaneous Threat Detection Systems. The hybrid model is comprised of mathematical and statistical data fusion engines; Dempster Shafer, Extended Dempster and Generalized Evidential Processing (GEP). Simultaneous Threat Detection Systems improve threat detection rate by 39%. In terms of efficiency and performance, the comparison of 3 inference engines of the Simultaneous Threat Detection Systems showed that GEP is the better data fusion model. GEP increased precision of threat detection from 56% to 95%. Furthermore, set cover packing was used as a middle tier data fusion tool to discover the reduced size groups of threat data. Set cover provided significant improvement and reduced threat population from 2272 to 295, which helped in minimizing the processing complexity of evidential processing cost and time in determining the combined probability mass of proposed Multiple Simultaneous Threat Detection System. This technique is particularly relevant to on-line and Internet dependent applications including portals.

Enhancing the Portal Experience

This article presents strategies for enhancing the long-term business and user value of portals as the third in a series of articles describing a Portal Design Framework. This article identifies essential Enterprise 2.0 functionality for collaboration and dialog—capabilities that support emerging Social Business practices—included in the Building Blocks Design Framework. The author discusses portal management and governance best practices and describes strategies for maintaining and enhancing the user experience of portals designed using the Building Blocks Framework.

Portals, Technology and E-Learning

E-learning promises to improve the learning process through the application of technology, including portal technology. Portals can provide the personalisation and interactivity functionality that e-learning requires. However, the long-held promise that technology will improve learning has often failed to deliver. This paper examines the promise of this technology and compares the specific demands of e-learning to the actual capability of portals and the underpinning Internet and World Wide Web. It then identifies four “costs” of using technology for e-learning, and points to existing project management tools that may minimise the effect of these “costs”.

Using Ajax to Track Student Attention

Tracking the behaviour of users of online learning systems is an important issue, but current techniques have not been able to give deep views on what users do with Web-based learning systems. This paper shows how the use of Ajax can provide a richer model of how users interact with Web systems. In this paper, the authors will discuss a case study used to better track behaviours of online learning systems and how Ajax improves this understanding of user interactions.

Search Integration with WebSphere Portal

Modern web applications and servers like Portal require adequate support for integration of search services due to user focused information delivery and user interaction, as well as new technologies used to render such information, which is exemplified by two fundamental problems that have long plagued web crawlers: dynamic content and Javascript generated content. Today, the solution is simple: ignore such web pages. To enable “search” in Portals, a different “crawling” paradigm is required to search engines to gather and consume information. WebSphere Portal provides a framework that propagates content and information through “Seedlists”—comparable to HTML based sitemaps but richer in terms of features. This mandates that information and content delivering applications must be “search engine aware”, requiring them to enable services and seedlists for fast, efficient and complete delivery of content and information. This is the main integration point for search engines into the portal for Portal site search services for a rich and user focused search experience. This article discusses how such technologies can allow for more efficient crawling of public Portal sites by prominent Internet search engines as well as myths surrounding search engine optimization.

Using the Building Blocks

This article is a case study that explores the use of the Building Blocks portal design framework over a series of enterprise portal projects spanning several years. This article describes the business contexts that shaped each portal as it was designed, showing the use and reuse of design and development elements based on the Building Blocks. This article discusses the changes and adaptations that shaped the elements of the Building Blocks design framework over time.

Challenges in Researching Portals and the Internet

The portal is a point of convergence for many uses and users. Along with the Internet itself, the portal crosses or combines many traditionally separate areas of research, each with its own perspective or perspectives. Such a combination creates a challenge for researchers on how to combine these various perspectives in examining portal and Internet use. This paper examines the methodological challenge by combining five perspectives: historical, technical, media, regulatory and business theory. The paper provides examples of the misunderstanding found regarding concepts that are fundamental and widely understood within a single field, but unknown or misunderstood outside of that field. This misunderstanding between business, technologists, media theorists and regulators contributed to the gulf between Internet investment expectation and the 2000 to 2001 results, the US$4 trillion ‘tech wreck’. Avoiding them will be important to the effective implementation of portal-based business solutions.

How Thick Is Your Client?

Average Revenue Per User (ARPU) is a measure of the revenue generated by users of a particular business service. It is a term most commonly used by consumer communications and networking businesses. For mobile devices, they generate ARPU through network and content services (value-added services) that they make accessible to the user. The more accessible these services are the greater the ARPU generated. The harder something is to find, the less likely someone is to use it. This paper explores the potential continuum between ARPU and service discoverability for mobile services by comparing and contrasting various technologies with respect to development, user experience, security, and commercialisation.

WSRP, SOA and UDDI

Web Services for Remote Portlets (WSRP) provide solutions for implementation of lightweight Service Oriented Architecture (SOA). UDDI extension for WSRP enables the discovery and access to user facing web services provided by business partners while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by web service providers from their own servers. Remote portlet consumers are not required to make any changes in their portals to accommodate updated remote portlets. This approach results in easier team development, upgrades, administration, low cost development and usage of shared resources. Furthermore, with the growing interest in SOA, WSRP should cooperate with service bus (ESB).In this paper, the author examines the technical underpinning of the UDDI extensions for WSRP (user facing remote web services) and their role in service sharing among business partners. The author also briefly outlines the architectural view of using WSRP in enterprise integration tasks and the role Enterprise Service Bus (ESB).

Do You Need a Content Management System?

Today the Web is used as a means to allow people and business to use services, get information and conduct transactions. Businesses today depend upon their visibility in their respective marketplaces and provision of e-services to customers. The Internet has become an important delivery mechanism of business visibility. Internet also significantly extends businesses capabilities to sell and buy worldwide. Therefore, the company website plays important role in maintaining and extending the business opportunities over the Internet.
