The ChemCollective (http://www.chemcollective.org/). is a digital library of activities for introductory college and high school chemistry. The collection includes virtual labs that allow students to design and carry out their own experiments, scenario based learning activities that invite students to apply their knowledge to real world situations, and interactive tutorials that support student...
The purpose of this study was to develop a Digital University model. The research method was qualitative which was used for this purpose meta synthesis. The research population consisted of 2600 scientific papers (including articles, books, dissertations and work reports), of which 84 were selected as sample. In order to validate the research findings, the critical tool of Glynn (2006) and the ...
Digital library systems with monolithic architectures are rapidly facing extinction as the discipline adopts new practices in software engineering, such as component-based architectures and Web Services. Past projects have attempted to demonstrate and justify the use of components through the construction of systems such as NCSTRL and ScholNet. This paper describes current work to push the boun...
3) Learning Objectives At the end of the module, student will be able to 1) Explain the basics of Image Retrieval and its needs in digital libraries. 2) Explain the different Image Retrieval types. 3) Classify Content Based Image Retrieval based on various features and differentiate between the techniques being used. 4) Explain the various Image Retrieval systems in existence and evaluation str...
The purpose of this study was to find out whether users should be involved in the design stage of a Digital Library (DL). Hence an experiment has been undertaken to find out the level of user satisfaction with a user-centred DL (UDL) compared to a non-user-centred DL (NDL). In this experiment, the UDL prototype has been compared with the NDL prototype. The two prototypes were then evaluated by ...
Grid technologies that have recently emerged around the world enable the integration of distributed computing resources. These technologies allow creating distributed grid services to hide the complexity of the underlying resource network and forming virtual organizations, which is the central concept of grid computing philosophy. Grid researchers and developers gather together under the auspic...
The overall goal of the Stanford Digital Library project is to provide an infrastructure that a ords interoperability among heterogeneous, autonomous digital library services. These services include both search services and remotely usable information processing facilities. In this paper, we survey and categorize the metadata required for a diverse set of Stanford Digital Library services that ...
To a great extent, ‘Semantics’ depends upon the context in which the user is seeking information. The proposed model aims at delivering information in the light of ontology-based document annotation, user annotation and domain ontology. The present study addresses the problem of semantic interoperability in digital library environment. In a heterogeneous environment, a mediation-based service i...
these two are in tension—data compression saves space, but at the expense of added access time; and indexing methods provide fast access, but usually at the expense of considerable amounts of additional storage space. Indeed, a complete index to a large body of text can be larger than the text itself—after all, it might store the location of every word in the text. The prospect of digital libra...
