We present ARISTOTELE, a platform for managing activities of knowledge-intensive enterprises, via the integration of tools and services for knowledge discovery, competence management, collaborative work and adaptive learning. We first present an overview of the platform with its main characteristics and its high-level tools. Then, we delve deeper i...

We present the architecture of the ARISTOTELE platform, a semantic-based collaborative system for managing enterprises and organizations, specifically designed to include a variety of features. These range from top-level functionalities like managing enterprise processes and building innovation, to finer-grained tasks like customized support for th...

We present the semantic-based architecture of the ARISTO-TELE platform, which is founded on the definition and development of models, methodologies, technologies and tools to support the emergence of competences and creativity within workers by self-organizing acquisi-tion, processing and sharing of new information inside knowledge-intensi-ve organ...

The adoption of high-level models for temporal, data-intensive Web sites is proposed together with a methodology for the design and development through a content management system (CMS). The process starts with a traditional ER scheme; the various steps lead to a temporal ER scheme, to a navigation scheme (called N-ER) and finally to a logical sche...

The Semantic Web is gaining increasing interest to fulfill the need of sharing, retrieving, and reusing information. In this context, the Resource Description Framework (RDF) has been conceived to provide an easy way to represent any kind of data and metadata, according to a lightweight model and syntaxes for serialization (RDF/XML, N3, etc.). Desp...

Ontologies have been frequently employed in order to solve problems derived from the management of shared dis- tributed knowledge and the efficient integration of information across different applications. However, the process of ontology building is still a lengthy and error-prone task. Therefore, a num- ber of research studies to (semi-)automatic...

In the last years, interoperability of ontologies and databases has received a lot of attention. However, most of the work has concentrated on specific problems (such as storing an ontology in a database or making database data available to ontologies) and referred to specific models for each of the two. Here, we propose an approach that aims at be...

Enterprise 2.0 is mainly focused on answering to people needs and to stimulate flexibility, adaptability and innovation. Ontologies define a common vocabulary to share domain information and are used to state the meaning of terms used in data produced, shared and consumed within the context of semantic Web applications. In this paper we propose a c...

The Semantic Web is an extension of the traditional Web aimed at facilitating information and knowledge sharing. In this context, RDF has been conceived as a means for a simple representation of any kind of data and metadata, according to a graph-based, lightweight model and a straight XML serialization. Although RDF has the advantage of being gene...

Multimodal interfaces can be profitably used to support the more and more complex applications and services which support human activities in everyday life. In particular, sketch-based interfaces offer users an effortless and powerful communication way to represent concepts and/or commands on different devices. Developing a sketch-based interface f...

In this paper the authors present two software solutions, developed in the context of the Business Experiment in GRID project (BEinGRID), and discuss on their applicability in the creation and management of distributed collaborative learning environments. In particular, the presented solutions are deemed useful to complete the current tools for the...

Multimodal interfaces can be profitably used to support in- creasingly complex services in assistive environments. In particular, sketch-based interfaces offer users an effortless and powerful communication way to represent concepts and commands on different devices. Unlike other modalities, sketch-based interaction can be easily fitted according t...

The ontologies are used to state the meaning of the terms used in data produced, shared and consumed within the context of Semantic Web applications. The folksonomies instead are an emergent phenomenon of the Social Web and represent the result of free tagging of information and objects in a social environment. Both ontologies and folksonomies are...

The success of today enterprises depends on their capability to respond on demand to challenging customers' request. At the same time, the enterprise marketplace is characterized by high dynamicity and heterogeneous requests. This makes difficult to provide in house cost-effective services able to meet them and, in many cases, the only solution is...

Ontologies define a common vocabulary to share domain information. Many researches have proved the importance of ontologies as a main technology for knowledge modelling. Moreover, many authors have emphasised the use of ontologies to augment the effectiveness of the management aspects of e-learning resources. In this paper, we present a set of meth...

This chapter describes multimodality as a means of augmenting information retrieval activities in multimedia digital libraries. Multimodal interaction systems combine visual information with voice, gestures, and other modalities to provide flexible and powerful dialogue approaches. The use of integrated multiple input modes enables users to benefit...

Human-to-human conversation remains such a significant part of our working activities because of its naturalness. Multimodal interaction systems combine visual information with voice, gestures, and other modalities to provide flexible and powerful dialogue approaches. The use of integrated multiple input modes enables users to benefit from the natu...

Semantic annotation remains a significant part of the semantic Web activities and a number of formalisms have been employed to annotate. Due to the impossibility of having a unique standard it may be important to have some techniques that allow the interoperability among the different kinds of annotations. We present an extension of our framework M...

The growing importance of RDF as a tool for describing information on the Web has risen a number of interesting works regarding the management of RDF documents. The effective management of RDF data has been an increasingly pressing active area of the current research. However current data management solutions for RDF data present the following shor...

Sketch-based interfaces enable users to effortless and powerfully communication way to represent concepts and/or commands, in different application domains, on different devices. Developing of a sketch-based interface for recognizing each specific domain is a timeconsuming operation that requires the re-engineering and/or the redesigning of the who...

Interoperability of ontologies and databases has received a lot of attention recently. However, most of the work has concentrated on specific problems (such as storing an ontology in a database or making database data available to ontologies) and referred to specific models for each of the two.

This chapter analyses the adoption of the Learning Grid for the development of challenging Application Scenarios in the eLearning domain. The Application Scenarios described in this chapter create a breakthrough in current learning practices. Instead of adopting a traditional information transfer paradigm, the proposed scenarios, in fact, promote a...

Semantic annotations represent a basic technology for the creation of meaningful content for the semantic Web. Many tools have been developed to realize semantic annotations platforms also using ontologies. An important characteristic such tools should satisfy is the semantic interoperability with other systems or tools. In this paper we examine pr...

This paper focuses on the concept of personalized e-Learning for the computer science (or informatics) education. Several authors have stated that personalization, in educational context, allows executing more efficient and effective learning processes. On the other side the use of Semantic Web technologies (e.g. ontologies) is more and more often...
