A Catalog of Web App for Smart Teaching

AppInventory is a Web platform, which proposes a holistic view on a digital catalog of 271 applications, an innovative visual layout, and semantic browsing structures; the applications have been organized in an original taxonomy and can support users in creating and sharing digital artifacts, aggregating, remixing and collecting heterogeneous materials and communicating within working groups

A state of art survey on zz-structures

Zz-structures are particular data structures capable of representing both hypertextual information and contextual interconnections among different information. The focus of this paper is to stimulate new research on this topic, by providing, in a state of the art survey, a short description and comparison of all the material that, to the best of our knowledge, is related to zz-structures: informal and formal descriptions, implementations, languages, demonstrations, projects and applitudes of zz-structures; in fact, despite their large use in different fields, the literature lacks of an exhaustive and up-to-date description of them

Modeling and developing a learning design system based on graphic organizers

Nowadays we assist to a significant innovation of the teaching practises due to the crisis of the classical teaching approach, the availability of low cost mobile technology and the easy access to global knowledge and information. Learning Design systems represent valuable tools to support teachers in the delicate task of organizing the teaching-learning activities in active student-centered approaches. There are many active projects in this field, but the available tools do not always fulfill the expectations. Furthermore, there is a rapid growth of Web 2.0 apps to create digital artefacts with a strong potential impact in learning activities, but current LD platforms don't guide teachers and students in choosing best apps to carry on a specific task. This paper provides an overview of the state of the art LD tools and developing perspective in this area

VisualBib: A novel Web app for supporting researchers in the creation, visualization and sharing of bibliographies

In this paper, we present VisualBib, a Web application, which allows users to create, visualize, modify, explore, and share bibliographies and the related citation networks, using innovative diagrams, called narrative views. The metadata are retrieved in real-time from four existing bibliographic indexes, Scopus, OpenCitations, and CrossRef/Orcid. Bibliographies and views are formally described and modeled using zz-structures, a semantic, not-hierarchical data model. VisualBib has been evaluated through two evaluation studies, one focused on the quantitative side and another on the qualitative side. Taking into account both studies, they evaluate the tool regarding the effectiveness performing tasks, usability, graphic layout and other questions specific to the VisualBib features. The evaluation throws positive significant results in all areas when compared to Scopus searching features

A formal description of zz-structures

The focus of this paper is on particular and innovative structures for storing, linking and manipulating information: The zz-structures. In the last years, we worked at the formalization of these structures, retaining that the description of the formal aspects can provide a better understanding of them, and can also stimulate new ideas, projects and research. This work presents our contribution for a deeper discussion on zz-structures

Extending the 5S Framework of Digital Libraries to support Complex Objects, Superimposed Information, and Content-Based Image Retrieval Services

Advanced services in digital libraries (DLs) have been developed and widely used to address the required capabilities of an assortment of systems as DLs expand into diverse application domains. These systems may require support for images (e.g., Content-Based Image Retrieval), Complex (information) Objects, and use of content at fine grain (e.g., Superimposed Information). Due to the lack of consensus on precise theoretical definitions for those services, implementation efforts often involve ad hoc development, leading to duplication and interoperability problems. This article presents a methodology to address those problems by extending a precisely specified minimal digital library (in the 5S framework) with formal definitions of aforementioned services. The theoretical extensions of digital library functionality presented here are reinforced with practical case studies as well as scenarios for the individual and integrative use of services to balance theory and practice. This methodology has implications that other advanced services can be continuously integrated into our current extended framework whenever they are identified. The theoretical definitions and case study we present may impact future development efforts and a wide range of digital library researchers, designers, and developers

Modelling Volo, an Augmentative and Alternative Communication application

In this paper, we present a formal representation of an Augmentative and Alternative Communication (AAC) application, called Volo, for users with Autism Spectrum Disorders (ASD). We discuss existing AAC applications and present a formal visualisation model of Volo based on zz-structures, hyper-orthogonal, non-hierarchical structures for storing, linking and manipulating data. To the best of our knowledge, this is the first work that tries to give a formal model to AAC techniques. We finally present the prototype of this new Volo application
