In this paper, we propose a novel approach for Web search based on the statistical information of local setting data of web browsers in a community. The members of the community share their local setting data of browsers and this enables them to take advantage of the peer community members's opinions in their Web search. Then we develop a new scheme that combines PageRank's link-based ranking scores with our proposed community based popularity scores for web sites. This hybrid scheme provides a rank- ordering method for search query results that integrates the content consumers' opinions with the content producers' opinions in a balanced manner. The users' opinions of web sites provide a solid starting point of trust for combatting web spam and improving the quality of Web search.

Many investigations have tried to depict the character of music file-sharing, identifying it with gift-giving, without explaining the connection but what kind of gift-giving procedure it is. It is believed that this identification is rather simplistic and in order to show the identity of both activities a comparison between them is reported, presenting a threefold categorization of differences in terms of product properties, procedure, and motives. It results that file-sharing is not gift-giving and that digital music has mostly the characteristics of a socially redistributed public good.

Social web platforms have become very popular in the so-called Web 2.0, and there is no end in sight. However, very few systematic models for the constitution of such socio-technical infrastructures exist in the scientific literature. We therefore present a generic framework for building social Web platforms based on the creation of value for individuals, communities and social networks. We applied this framework in the Neurovation project, aiming to establish a platform for creative knowledge workers. This paper describes work in progress and the lessons we have learned so far.

The Semantic Web is a vision for the future of the Web in which information is given explicit meaning, making it easier for machines to automatically process and integrate information available on the Web. An ontology defines the terms used to describe and represent an area of knowledge. Ontologies are used by people, databases, and applications that need to share domain information (a domain is just a specific subject area or area of knowledge, like medicine, tool manufacturing, real estate, automobile repair, financial management, etc.). In this paper we combine this two concepts to annotate models with meta-data according to the corresponding domain ontology with all the new extracted information in order to improve the performance of the entire system.

Mobile devices are increasingly evolving into tools to orientate in and interact with the environment, thus introducing a user-centric approach to ambient intelligence. The MINAmI project aims at creating core technologies for these kinds of ambient intelligence services. In this paper we assess five scenarios that demonstrate forthcoming MINAml-based devices. A brief legal and ethical analysis of the scenarios is conducted, which reveals various conflicting interests. The paper concludes with some thoughts on drafting ethical guidelines for ambient intelligence applications, as the nature and the needs of such applications are intrinsically different from the ones ethical guidelines have been dealing with earlier.

Peer-to-peer (P2P) systems are widely used for sharing digital items without structured metadata and in absence of any kind of digital rights management applied to the distributed contents. In this paper we propose the implementation of a prototype application that makes use of a structured P2P system enabling the indexing of complex metadata, used to express digital rights. In this way the media contents are exchanged and played according to the expressed grants. The creation and the consumption of the shared contents can be performed through any MPEG-21 REL compliant software and the application allows indexing and search for both governed and ungoverned contents. The information about the license can be included in the queries and the P2P network can be used to share governed contents (both free and with fee) in a legitimate way. In particular the proposed approach represents a suitable solution for indexing and querying rights complex structures on DHT based networks.

Usability testing is a technique for measuring a system's usability. It consists of a number of variables such as tasks, number of users, evaluators, and other elements. This paper explores the proposal that task design can seriously influence the usability testing results. It describes how two different types of task affect results. The types explored are structured tasks and uncertain tasks. Each type of task seems to discover different types of problems. In addition, in this research, the magic number of "five users" fails to achieve the promised 85% of usability problems.

Service oriented architecture (SOA) supports the integration of distributed and heterogeneous services by offering Web service composition standards which describe service composition as a business process. However, the composition model proposed in SOA does not explicitly deal with personalization and context-awareness. In order to address such limitations, we have developed the CAWE conceptual framework. In this paper, we describe the personalization support offered by our framework to the development of context-aware, adaptive Web-based systems. CAWE handles the integration of heterogeneous services and information sources; moreover, it manages long-lasting interactions with multiple cooperating users and it personalizes the business logic of the application by adapting the workflow activities to be carried out.

The activities developed by a company (business processes) have to change frequently to adapt to the environment. The implementation of business processes should support these changes without any receding. In this work, we provide with an approach for modelling and executing agile and adaptable business processes. Our approach is based on UML2 separating choreography (stable interaction patterns) and orchestration (implementation of the evolving business process, also called workflows), allowing the transformation and execution of the models by means of a flexible SOA-based dynamic platform based on reference Petri nets.

There is growing interest in promoting interoperability among the many different existent grid initiatives. The requirements for interlinking of grids have already been studied from a general point of view. In this paper, we analyse current practice in grid interactions and show evidence of how grid interactions may represent a barrier for interlinking of grids. Our proposal consists of three combined aspects: a) explicitly modelling the interactions (what we call interaction protocols), b) decoupling the execution flow of services from their interactions with other services and c) services have to be able to dynamically select the interaction protocol at the time they have decided to interact with another party. Next, for a clarifying purpose, we show how DVega, an application built on the proposed principles, can use these features as the foundations for interacting with disparate services from different grids in a flexible and dynamic way.
