In this paper we provide experimental results and extensions to our previous theoretical findings concerning the combination of forecasts that have been diversified by three different methods: with parameters learned at different data aggregation levels, by thick modeling and by the use of...

The parameter in negative correlation learning (NC) controls the degree of co-operation between individual networks. This paper looks at the way the choice of in the NC algorithm affects the complexity of the function NC can fit, and shows that it acts as a complexity control allowing smooth...

This paper provides a description and experimental comparison of different forecast combination techniques for the application of Revenue Management forecasting for Airlines. In order to benefit from the advantages of forecasts predicting seasonal demand using different forecast models on...

Process modelling is gaining increasing acceptance by software engineers as a useful discipline to facilitate both process understanding and improvement activities. This position paper builds upon previous work reported at the 1997 ICSE workshop on process models and empirical studies of...

Over the years, there has been much interest in modelling processes. Processes include those associated with the development of software and those business processes that make use of software systems. Recent research in Systems Engineering for Business Process Change highlights the importance of...

By providing a route from model to architecture, Model Driven Architecture (MDA) promises, among other things, to narrow the gap between business users and software developers. That is, the approach is intended to involve stakeholders in modelling, so that, by transformation from Computationally...

A system has been developed that analyses the emotional content of web pages. Text is extracted from an embedded Internet browser and sent to a text-to-emotion engine that identifies the emotive content. An experiment was conducted that examines the effect the emotional content of the web page...

This article reports on the latest developments of our Emotional Stock Analyser application. The original application automatically analyses the text that is input by the user, using a text-to-emotion engine that identifies the emotive content. The whole text of newspaper articles about the...

One of the motivations for a model driven approach to software development is to increase the involvement for a range of stakeholders in the requirements phases. This inevitably leads to a greater diversity of roles being involved in the production of models, and one of the issues with such...

The use of formal models such as Role Activity Diagrams (RADs) for analysing a process often hide what really happens during that process. In this paper, we build on previous research on informal aspects of the prototyping process and look at the key concerns that prototypers had during the...
