Internet is being used increasingly as a resource for accessing healthrelated information because of its several advantages. Therefore, Internet tailoring becomes quite preferable in health education and personal health management recently. Today, there are many web based health programs designed for individuals. Among these studies nutrition and weight management is popular because, obesity ha...

Recently new techniques to efficiently manage biological information of biology have played an important role in the area of information technology. The flavonoids are members of a class of natural compounds that recently has been the subject of considerable scientific and therapeutic interest. This paper presents a Grid-based flavonoids web portal system. We designed relational schema, XML sch...

This paper proposes a methodology to optimise the future accuracy of a collaborative recommender application in a citizen Web portal. There are four stages namely, user modelling, benchmarking of clustering algorithms, prediction analysis and recommendation. The first stage is to develop analytical models of common characteristics of Web-user data. These artificial data sets are then used to ev...

Today’s organisations are increasingly relying on the web to support their operations and the integration of their processes with their partners’. Portlets, which are distributed web components that encapsulate web applications, are considered a promising breakthrough towards this aim. The goal is to define a component model to enable portlets to be easily plugged into web portals. This article...

As an emerging form of enabling technology, Web-based e-Health portals provide patients easier accesses to their healthcare information and services. We design and implement such an e-Health portal which can integrate many backend medical services effectively. A major challenge in designing such a system is to meet critical security requirements, such as the confidentiality of patient data, the...

The paper presents observations concerning teaching Prolog to computer science students. Basing on these experiences an interactive web-portal is proposed to support teaching. Some guidelines for portal features are given. A prototype implementation based on DokuWiki is also described.
