Delivering Categorized News Items Using RSS Feeds and Web Services

In the past decade the massive growth of the Internet brought huge changes in the way humans live their daily life; however, the biggest concern with rapid growth of digital information is how to efficiently manage and filter unwanted data. In this paper, we propose a method for managing RSS feeds from various news websites. A Web service was developed to provide filtered news items extracted from RSS feeds and these were categorized based on classical text categorization algorithms. A client application consuming this Web service retrieves and displays such filtered information. A prototype was implemented using Rapidminer 4.3 as a data mining tool and SVM as a classification algorithm. Experimental results suggest that the proposed method is effective and saves a significant amount of user processing time.

Enhancing UDDI for grid service discovery by using dynamic parameters

A major problem for a grid user is the discovery of currently available services. With large number of services, it is beneficial for a user to be able to discover the services that most closely match their requirements. This report shows how to extend some concepts of UDDI such that they are suitable for dynamic parameter based discovery of grid services.

A Multilevel Trust Management Framework

Lack of trust in e-commerce transactions has been identified by researchers as one of the main factors that hamper e-commerce from reaching its full potential. Various trust-related supporting features for online transactions are available to improve trust management. However, most of these existing approaches have insufficient conditions to establish online trust among businesses and customers. There are many relevant factors that influence potential buyers to make decisions. In this paper, we identify several desirable properties of an ideal trust management system that existing trust management systems do not support. A multilevel trust management framework is proposed to improve the support for existing trust management in e-commerce.

Enhancing web-based adaptive learning with colored timed Petri net

One of the issues for Web-based learning applications is to adaptively provide personalized instructions for different learning activities. This paper proposes a high level colored timed Petri Net based approach to providing some level of adaptation for different users and learning activities. Examples are given to demonstrate how to realize adaptive interfaces and personalization. Future directions are also discussed at the end of this paper.

An IT Bachelor Degree Using Modern Technologies to Illustrate Core Concepts and Principles and Building Generic Skills

Information Technology (IT) changes very quickly and influences business, industry and the public in an enormous manner. Outsourcing of IT jobs to cheaper overseas labor and globalization of IT companies become a common practice. Graduates of IT university courses must be well prepared to address the needs and expectations of business, industry and every day life. Many factors in an Information Technology curriculum influence graduates’ professional preparation and image. The most important of them is to reflect technology change, the current state of knowledge of computing, business and industry demands and students’ expectations. The aim of our project was to develop a new Bachelor of IT curriculum that satisfies these requirements. In this report we concentrate our attention on two critical aspects of IT curriculum content, the modern technologies to be used to illustrate basic concepts and principles of computing, and the generic skills that each graduate is expected to acquire to get a job in Australia.

Towards a framework for aligning learning outcomes, academic literacies and assessment criteria

Although Australian students spend three or more years studying they can seem quite unaware of any of the expected learning outcomes of their course. They are often single unit focused, paying most attention to individual assessment items thus not developing a holistic view of their course. This paper presents a theoretical framework to support staff and students to recognise, scaffold and achieve learning outcomes and academic skills at unit level and to recognise how these contribute to course and graduate learning outcomes, within the boundaries of Australian university and professional accreditation requirements. A case study is described that demonstrates the manual implementation of the framework. The complex nature of the implementation suggests that a software solution is required to ease the process and ensure the resulting mapping will have some longevity by being maintainable.

The Development of a Language for Specifying Structure of a Distributed and Parallel Application

A common characteristic of distributed and parallel programming languages is that the one language is used to specify both the organisation of the application, and its functionality. Large distributed and parallel applications will benefit if connectivity and functionality of processes are specified separately. Research is being carried out to develop two new programming languages for the specification and development of distributed and parallel applications. Here, we present a language for specifying process connectivity.

A rapid prototyping system for real-time systems

A rapid prototyping system has been developed which can be used to build an executable model from the graphical specifications of a real-time system. The notation used for such specifications is the transformation schema [Ward and Mellor (1985)]. The rapid prototyping system allows the user to create a schema of a real-time system; compile an executable, object-oriented model of the schema; and finally link the executable model, schema and user by creating two interfaces. This linking stage produces an interactive and executable prototype of the schema. The creation of this executable prototype is completely automatic except for designing the transformation schema which is built manually using a graphical editor.
