The Thesaurus for the Social Sciences (TheSoz) is a Linked Dataset in SKOS format, which serves as crucial instrument information retrieval based on e.g. document indexing or search term recommendation. Thesauri and similar controlled vocabularies build linking bridge other datasets from Open Data cloud - even between different domains. knowledge, exposed by such links, can be processed Semantic Web applications. In this article conversion process of TheSoz to described including analysis...
This paper describes the open access graph dataset that shows connections between Dryad, CERN, ANDS and other international data repositories to publications grants across multiple research infrastructures. The was created using Research Graph model Data Switchboard (RD-Switchboard), a collaborative project by Alliance DDRI Working Group (DDRI WG) with aim discover connect related datasets based on publication co-authorship or jointly funded grants. allows researchers trace follow paths...
In the social sciences, researchers search for information on Web, but this is most often distributed different websites, portals, digital libraries, data archives, and databases. work, we present an integrated system science that allows finding around research in a single library. Users can sets, publications, survey variables, questions from questionnaires, instruments, tools. Information items are linked to each other so users see, example, which publications contain citations data. The...
With the rise of open data movement a lot statistical has been made publicly available by governments, offices and other organizations. First efforts to visualize are providers themselves. Data aggregators go step beyond: they collect from different repositories make them comparable providing sets showing statistics in same chart. Another approach is two indicators scatter plot or on map. The integration several one graph can have drawbacks: scales units mixed, gets visually cluttered cannot...
In the area of Linked Open Data (LOD) meaningful and high-performance interlinking different datasets has become an ongoing challenge. Necessary tasks are supported by established standards software, e.g. for transformation, storage, publication data. Our use case Swissbib is a well-known provider bibliographic data in Switzerland representing various libraries library networks. this article, study presented from project linked.swissbib.ch which focuses on preparation means LOD. available...
Research on environmental justice comprises health and well-being aspects, as well topics related to general social participation. In this research field, among others, there is a need for an integrated use of science survey data spatial data, e.g. combining demographic information from with pollution data. However, researchers it challenging link both sources, because (1) the interdisciplinary nature sources different, (2) underlie different legal restrictions, in particular regarding...
In this paper we present a novel method to connect data on the visualization level. general, visualizations are dead end, when it comes reusability. Yet, users prefer work with as evidenced by WYSIWYG editors. To enable their in way that is intuitive them, have created Vizgr. Vizgr.com offers basic methods, like graphs, tag clouds, maps and time lines. But unlike normal visualizations, these can be re-used, connected each other web sites. We offer simple opportunity combine diverse...
From 2012 to 2015 together with other Linked Data community members and experts from the social, behavioral, economic sciences (SBE), we developed diverse vocabularies represent SBE metadata tabular data in RDF. The DDI-RDF Discovery Vocabulary (DDI-RDF) is designed support dissemination, management, reuse of unit-record data, i.e., about individuals, households, businesses, collected form responses studies archived for research purposes. RDF Cube (QB) a W3C recommendation expressing cubes,...
To ensure high quality of and trust in both metadata data, their representation RDF must satisfy certain criteria - specified terms constraints. From 2012 to 2015 together with other Linked Data community members experts from the social, behavioral, economic sciences (SBE), we developed diverse vocabularies represent SBE rectangular data RDF. The DDI-RDF Discovery Vocabulary (DDI-RDF) is designed support dissemination, management, reuse unit-record i.e., about individuals, households,...
For research institutes, data libraries, and archives, RDF validation according to predefined constraints is a much sought-after feature, particularly as this taken for granted in the XML world. Based on our work DCMI Application Profiles Task Group cooperation with W3C Data Shapes Working Group, we identified published by today 81 types of that are required various stakeholders applications. In paper, collaboration several domain experts formulate 115 three different vocabularies (DDI-RDF,...
