The increase in computational power and the networking abilities of home appliances are revolutionizing the way we interact with our homes. This trend is growing stronger and opening a number of technological challenges. From the point of view of distributed systems, there is a need to design architectures for enhancing the comfort and safety of the home, which deal with issues of heterogeneity, scalability and openness. By considering the evolution of domotic research and projects, we advocate a role for web services in the domestic network, and propose an infrastructure based on web services. As a case study, we present an implementation for monitoring the health of an elder adult using multiple sensors and clients.
In the analysis of a newspaper page an important step is the clustering of various text blocks into logical units, i.e., into articles. We propose three algorithms based on text processing techniques to cluster articles in newspaper pages. Based on the complexity of the three algorithms and experimentation on actual pages from the Italian newspaper L’Adige, we select one of the algorithms as the preferred choice to solve the textual clustering problem.

The shift in software engineering from the design, implementation and management of isolated software elements towards a network of autonomous interoperable service is calling for a shift in the way software is designed. We propose the use of the agent-oriented methodology Tropos for the analysis of web service requirements. We show how the Tropos methodology adapts to the case of web services and in particular how it can be used to model quality of service requirements.
We base the investigation on a representative case study in the retailing industry.
Qualitative reasoning about mereotopological relations has been extensively investigated, while more recently geometrical and spatio-temporal reasoning are gaining increasing attention. We propose to consider mathematical morphologic operators as the inspiration for a new language and inference mechanism to reason about space. Interestingly, the proposed morphologic captures not only traditional mereotopological relations, but also notions of relative size and morphology. The proposed representational framework is a hybrid arrow logic theory for which we define a resolution calculus which is, to the best of our knowledge, the first such calculus for arrow logics.
One of the common metaphors used in textbooks on Object-Oriented programming (OOP) is to view objects in terms of the services they provide, describing them in “service oriented” terms. This opens a number of interesting questions, moving away from the simple view of OOP as an implementation tool for Web Services. First of all: if an Object is a Service, can we also say that a Service is an Object? While the short answers seems to be negative, there are several connections between the two concepts and it is possible to exploit the large repository of methodological tools available in OOP. What are the counterparts, in terms of services, of concepts like class or instance? Is it possible to apply techniques as containment or inheritance to services? What are interfaces, properties and methods for services? In this paper we try to start ...
We use a propositional language of qualitative rectangle relations to detect the reading order from document images. To this end, we define the notion of a document encoding rule and we analyze possible formalisms to express document encoding rules such as LATEX and SGML. Document encoding rules expressed in the propositional language of rectangles are used to build a reading order detector for document images. In order to achieve robustness and avoid brittleness when applying the system to real life document images, the notion of a thick boundary interpretation for a qualitative relation is introduced. The framework is tested on a collection of heterogeneous document images showing recall rates up to 89%.

Interaction with web services enabled marketplaces would be greatly facilitated if users were given a high level service request language to express their goals in complex business domains. This could be achieved by using a planning framework which monitors the execution of planned goals against predefined standard business processes and interacts with the user to achieve goal satisfaction. We present a planning architecture that accepts high level requests, expressed in XSRL (Xml Service Request Language). The planning framework is based on the principle of interleaving planning and execution. This is accomplished on the basis of refinement and revision as new service-related information is gathered from UDDI and web services instances, and as execution circumstances necessitate change. The system interacts with the user whenever conf...
Non-functional properties of services and service compositions are of paramount importance for the success of web services. The negotiation of non-functional properties between web service provider and consumer can be agreed on a priori, by specifying an agreement. WS-Agreement is a recently proposed and emerging protocol for the specification of agreements in the context of web services. Though, WS-Agreement only specifies the XML syntax and the intended meaning of each tag, which naturally leads to posing the question of “What’s in an Agreement?” We answer this question by providing a formal definition of an agreement and analyzing the possible evolution of agreements and their terms. From our analysis it turns out that agreements can be made more robust and longer-lived by a simple extension, which we present.
