This paper presents the approach and first results of the classification mapping process in the EU project Renardus. The outcome in Renardus is a cross-browsing feature based on the Dewey Decimal Classification (DDC) and improved subject searching across distributed and heterogeneous European subject gateways. The paper presents the project's initial experiences and decisions, e.g. an investigation of the use of classification systems by Renardus partners' gateways, general mapping approaches and issues, the definition of mapping relationships and some information on technical solutions and the mapping tool. There is also a demonstration of the use of the mapping information in Renardus and the presentation of several features that have been implemented to aid end-user navigation in a large and deep browsing structure like the DDC. Classification mapping for crossbrowsing is a labour intensive and complex effort which at the moment raises many open questions and leaves many more future potential work tasks than completed useful solutions.
The TextGrid research group, a consortium of 10 research institutions in Germany, is developing a virtual research environment for researchers in the arts and humanities that provides services and tools for the analysis of text data and supports the curation of research data by means of grid technology. The TextGrid virtual research environment consists of two main components: the TextGrid Laboratory (TextGridLab), which serves as the entry point to the virtual research environment, and the TextGrid Repository (TextGridRep), which is a long-term humanities data archive ensuring sustainability, interoperability and long-term access to research data. To support all stages of the research lifecycle, preserve and maintain research data, and ensure its long-term usefulness, existing research practices must be supported. Therefore the TextGridLab provides common functionalities in a sustainable environment to intensify re-use of data, tools, and services, and the TextGridRep enables researchers to publish and share their data in a way that supports long-term availability and re-usability.
International audienceIn recent years, a variety of initiatives have been funded with the aim of producing software tools or environments of a type variously known as virtual research environments, research infrastructures, or cyberinfrastructures. These initiatives vary in their scale, specialization, scope, and level of funding. One issue that they face in common, however, is that of sustainability: how can the continued--and useful--existence of a system or tool be guaranteed, or at least facilitated, once a project's funding has been spent? In this paper, we examine how such sustainability has been enabled, in the particular case of infrastructures for textual scholarship, in the context of three international projects: TextGrid,1 TEXTvre,2 and DARIAH3. Firstly, we will address the inter-project collaboration and crossfertilization between TextGrid and TEXTvre, including architectural decisions and shared data infrastructures, and investigate how the projects benefited from the exchange. We will then discuss how this existing collaboration can be taken forward by the loosely-coupled and distributed framework being developed by the DARIAH community, and how it can serve as a model for the sort of collaborations that DARIAH plans to enable
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
