Current web application development requires highly qualified staff, dealing with an extensive number of architectures and technologies. When these applications incorporate semantic data, the list of skill requirements becomes even larger, leading to a high adoption barrier for the development of semantically enabled Web applications. This paper describes VPOET, a tool focused mainly on two types of users: web designers and web application developers. By using this tool, web designers do not need specific skills in semantic web technologies to create web templates to handle semantic data. Web application developers incorporate those templates into their web applications, by means of a simple mechanism based in HTTP messages. End-users can use these templates through a Google Gadget. As web designers play a key role in the system, an experimental evaluation has been conducted, showing that VPOET provides good usability features for a representative group of web designers in a wide ra...

This paper shows a semantically-enabled Web application named MIG used to create user profiles which enhances users accessibility by allowing the creation of an user interface adapted to the user needs, the device used, and its preferences. This approach exploits the Semantic Web technologies and the infrastructure and applications created in previous work.

This paper describes a distributed collaborative wiki-based platform that has been designed to facilitate the development of Semantic Web applications. The applications designed using this platform are able to build semantic data through the cooperation of different developers and to exploit that semantic data. The paper shows a practical case study on the application VPOET, and how an application based on Google Gadgets has been designed to test VPOET and let human users exploit the semantic data created. This practical example can be used to show how different Semantic Web technologies can be integrated into a particular Web application, and how the knowledge can be cooperatively improved.

We describe VPOET templates, web templates to present or request semantic data to or from end users. These templates can be used by web developers with no competencies in Semantic Web by means of simple HTTP messages. Although its application to wiki environments is only pointed, a real application oriented to end users is shown. This experience shows that VPOET templates can be easily integrated in web applications written in any programming language..

Over the last decade there has been a growing interest on Intelligent Agents and Multi-Agent Systems (MAS) in several fields such as Artificial Intelligence (AI), Software Engineering, Psychology, etc... Different problems can be solved in these fields by creating societies of agents that communicate with each other. Nevertheless, when the number of agents is large and the connectivity is extensive,

Compression distances have been widely used in knowledge discovery and data mining. They are parameter-free, widely applicable, and very effective in several domains. However, little has been done to interpret their results or to explain their behavior. In this paper, we take a step toward understanding compression distances by performing an experimental evaluation of the impact of several kinds of

The interest of the Education community for Virtual Reality (VR) technologies has increased in the last few years due to their attractive 3D immersive worlds and facilities to provide a good environment to develop educational and collaborative tasks. However, these technologies present three main drawbacks: (1) a high cost in terms of hardware and infrastructure, (2) a high level of technology knowledge, and usually programming skills, is required to build up an educational and functional platform, and (3) once the educational platform is available for use, the educators are limited to the functionalities provided by the platform used. Our previous experience, designing and deploying a VR educational platform, named V-LeaF, showed that non immersive platforms (close to the gaming 3D platforms) provide High School educators and students with an attractive environment in which many features of the teaching/learning experience can be explored. However, this technological strength appea...

The logistics sector is a very dynamic and complex domain with large impact in our day-to-day life. It is also very sensitive to the market changes, so tools that can improve their processes are needed. This paper describes a decision support tool for a Spanish Logistics Company. The tool takes the knowlege from the human drivers, ie the address used to deliver a package, integrates and exploits it into the decision process. However, this is precisely the data that is often wrongly introduced by the drivers. The tool analyses and ...

In this paper we present an overview of SHAMASH, a process modelling tool for business process reengineering. The main features that differentiate it from most current related tools are its ability to define and use organisation standards, and functional structure, and make automatic model simulation and optimisation of them. SHAMASH is a knowledge-based system, and we include a discussion on
