Interaction with linked digital memories
No full textThis paper presents a starting project on Web of Things and Linked Data. Physical objects are provided with a digital memory that enables them to store data about themselves and to link other resources in the Linked Data cloud. This possibility radically transforms the interaction with real objects and the user experience with the Web. In this scenario, personalization seems an opportunity and a requirement. The physical objects used in the project are mu-seum artefacts. The paper describes architecture and main modules
Virtualization of Objects and Adaptive Interaction in an Inclusive Web of Things
No full textIn the near future we will be surrounded by plenty of smart interconnected objects and by objects linked to their virtual counterpart on the Web. The availability of a virtual object connected to the physical object can be an extraordinary opportunity to make physical objects accessible and inclusive. However, to exploit this opportunity and to avoid that the Internet of Things increases the technological gap between users, an orchestration of such objects is necessary as well as adaptive mechanisms that automate the tuning and customization of the applications that manage virtual objects, in order to fit the specific user needs. This contribution presents issues relating to virtualization of physical objects and describes the basics of an adaptive management of Web of Things applications
Social Tagging in eLearning. Recommendations from Virtual Fellow-Students
No full textThe paper deals with the issue of exploiting social tagging in the eLearning domain. After analyzing its main functions and possible uses, it presents an ongoing project for a tag-based personalized search engine and discusses its application to the eLearning domai
Adaptive systems in the era of the semantic and social web, a survey
No full textThis paper presents an analysis and a classification of adaptive systems with respect
to the kind of semantic technology they exploit to accomplish or improve specific adaptation
and user modeling tasks. This classification is based on a distinction between
strong semantic techniques and weak semantic techniques. The former techniques are
based on the Semantic Web, while the latter regard technologies that, in different ways,
annotate resources, enriching their meaning. This second category includes, in particular,
Web 2.0 social annotations and mixed approaches between social annotations
and Semantic Web techniques. While the impact of the Semantic Web on adaptive
systems has been discussed in several survey papers, the potential of weak semantic
technologies has received less attention. The original contribution of this study is to fill this
gap by providing an overall analysis of the use of all forms of knowledge annotation to implement and carry out task and sub-tasks of user modelling and user-adapted systems
Goals, Tasks and Application Domains as the Guidelines for Defining a Framework for User Modelling
No full textThe exponential increase of adaptive systems and the difficulty of identifying the relevant dimensions for the construction of user models, are the bases of the choice of building a framework for user modelling. The goal is that of defining a method for identifying such dimensions and moreover creating a taxonomy of goals, features and dimension for different application domains
Users Modeling for Adaptive Call Centers
No full textThe project described in this paper applies the principles of adaptivity to a “traditional” Call Center in order to support the Operator in the interaction with the Customer. The system uses the models of both the Customer and the Operator and builds up the stepwise answer through an adaptive workflow
A Modular Approach for User Modelling
No full textAdaptive hypermedia systems are spreading widely in these last years, but each application uses its own models and techniques.The paper deals with the possibility of developing a framework for user modelling in adaptive systems and in particular of creating a library of stereotypes for representing the different dimensions of the user models
The Importance of Adaptivity to Provide Onboard Services. A Preliminary Evaluation of an Adaptive Tourist Information Service Onboard Vehicles
No full textThis paper presents an adaptive onboard tourist guide and its experimental evaluation. The guide is an adaptive system which modifies its behaviour (time of activation, content, presentation layout) according to a model it dynamically builds about the user (driver) and the context of interaction (time, location and driving conditions). After a short description of the role that adaptation can play in mobile systems installed on vehicles, the paper describes goals and architecture of the system, focusing on the forms of adaptation it implements. Finally the paper presents an evaluation exercise carried out to test the system. This preliminary evaluation is very promising as regards both suggested content and the way they are provided. This last issue is particularly critical for the driver safety and depends on a proper evaluation of the user capabilities and of the contextual situation
Adaptive Management of the Answering Process for a Call Center System
No full textThis paper describes the development of an Adaptive Call Center which personalizes the management of the answering process. The system is composed by an adaptive response system with a speech recognition engine and by an operator support structure, which is dynamically involved in the answer when the sentence is not recognized or the question belongs to those classified as complex. In this case the call is routed to the operator which best fits the caller feature
