A Method to Screen, Assess, and Prepare Open Data for Use

Open data's value-creating capabilities and innovation potential are widely recognized, resulting in a notable increase in the number of published open data sources. A crucial challenge for companies intending to leverage open data is to identify suitable open datasets that support specific business scenarios and prepare these datasets for use. Researchers have developed several open data assessment techniques, but those are restricted in scope, do not consider the use context, and are not embedded in the complete set of activities required for open data consumption in enterprises. Therefore, our research aims to develop prescriptive knowledge in the form of a meaningful method to screen, assess, and prepare open data for use in an enterprise setting. Our findings complement existing open data assessment techniques by providing methodological guidance to prepare open data of uncertain quality for use in a value-adding and demand-oriented manner, enabled by knowledge graphs and linked data concepts. From an academic perspective, our research conceptualizes open data preparation as a purposeful and value-creating process.

AGROVOC: The linked data concept hub for food and agriculture

Newly acquired, aggregated and shared data are essential for innovation in food and agriculture to improve the discoverability of research. Since the early 1980′s, the Food and Agriculture Organization of the United Nations (FAO) has coordinated AGROVOC, a valuable tool for data to be classified homogeneously, facilitating interoperability and reuse. AGROVOC is a multilingual and controlled vocabulary designed to cover concepts and terminology under FAO's areas of interest. It is the largest Linked Open Data set about agriculture available for public use and its highest impact is through facilitating the access and visibility of data across domains and languages. This chapter has the aim of describing the current status of one of the most popular thesaurus in all FAO’s areas of interest, and how it has become the Linked Data Concept Hub for food and agriculture, through new procedures put in place.

SCALEUS-FD: A FAIR Data Tool for Biomedical Applications.

The Semantic Web and Linked Data concepts and technologies have empowered the scientific community with solutions to take full advantage of the increasingly available distributed and heterogeneous data in distinct silos. Additionally, FAIR Data principles established guidelines for data to be Findable, Accessible, Interoperable, and Reusable, and they are gaining traction in data stewardship. However, to explore their full potential, we must be able to transform legacy solutions smoothly into the FAIR Data ecosystem. In this paper, we introduce SCALEUS-FD, a FAIR Data extension of a legacy semantic web tool successfully used for data integration and semantic annotation and enrichment. The core functionalities of the solution follow the Semantic Web and Linked Data principles, offering a FAIR REST API for machine-to-machine operations. We applied a set of metrics to evaluate its “FAIRness” and created an application scenario in the rare diseases domain.

Making Linked Data more reliable with a failover server system: a case study with seismological data at INGV.

Since the introduction of the Linked Data concept more than a decade ago, today the way scientists use and share their research data is increasingly changing. The growing availability of big amounts of Open Research Data is challenging the old-fashioned habit of replicating large datasets locally prior to their processing, and the new Open Science paradigm tries to update the way researchers works by pushing them into solutions enabling a quicker, lightweight and more efficient circulation of research results. Granting access to its data resources is an activity taken very seriously at INGV, moreover as it is head of two important European Research Infrastructure Consortium (ERIC), namely the European Multidisciplinary Seafloor and water-column Observatory (EMSO), and the European Plate Observing System (EPOS). As more and more data are becoming accessible via web services, an increasing number of researchers are starting to include their use in their workflows, thus, heavily relying on their correct and continuous operational functioning, in other words, in their service continuity. Experimenting solutions for enhancing the reliability of web services is at the core of the present work. We propose here a solution that is able to guarantee the functioning of a service in case of an IT infrastructure fail, a mechanism that is able to automatically switch to a secondary server located in another network. The solution is made possible thanks to a collaboration with GARR, the ultra-broadband network dedicated to the Public Italian Research, and is able to deal with network problems, server hardware problems, as well as service level problems.

Adoption of linked data technologies among university librarians in Pakistan: Challenges and prospects

This study aims to explore librarians’ perspective about the adoption of Linked Data technologies along with their level of interest to adopt these technologies in Pakistani university libraries. It also identifies their perceived hindrances that obstruct them to adopt and effectively implement Linked Data technologies in libraries. This is a quantitative study based on survey research design. To meet the objective of the study, a self-constructed and validated questionnaire was used to collect data. Findings show that university librarians believe in the effective adoption of Linked Data technology in libraries. They perceive that Linked Data technology can enhance navigation between the traditional online tools to access library resources and Linked Data will soon be the standard for creating metadata and records for information resources management in libraries. They are eager to attend events about Linked Data application in their libraries and willing to explore ways to incorporate Linked Data standards in bibliographic records management as well. Barriers do exist such as the general lack of awareness of basic Linked Data concepts and best practices for this emerging technology. To foster the research and to set Linked Data best practices in libraries and other cultural heritage institutions, there is a potential to invest in this area in terms of financial and social capital.

Linked Data in a Nutshell: A Starter Kit of Selected Annotated Bibliography and Resources for Academic Librarians: Part One

It has been a decade since Tim Berners-Lee coined Linked Data in 2006. More and more Linked Data datasets have been made available for information retrieval on the Web. It is essential for librarians, especially academic librarians, to keep up with the state of Linked Data. There is so much information about Linked Data that one may wonder where to begin when they want to join the Linked Data community. With this in mind, the author compiled this annotated bibliography as a starter kit. Due to the many resources available, this list focuses on literature in English only and of specific projects, case studies, research studies, and tools that may be helpful to academic librarians, in addition to the overview of Linked Data concept and the current state of Linked Data evolution and adoption.

Pemanfaatan Linked Data untuk Meningkatkan Kualitas Information Knowledge pada Resources Game Online

This paper proposes an online game design that has resources with interoperability. Interoperability means the resources can share, re-used, and interlinked with another Unified Resources Identifier (URI). The game design is constructed by utilizing Linked Data concept where the resources are developed in the form of ontology. The resources are developed by both creating manually using Protege and re-using from another URI’s. To get the resources from another URI’s SPARQL can be used through Apache Jena Fuseki server. SPARQL is a query used for Resource Description Framework (RDF) or Web Ontology Language (OWL). The result shows that retrieval data/information process by using SPARQL works well. The resources from another URI’s can be used and integrated with local resources. It means the quality of information knowledge is increasing in interoperability, where the resources can be shared, re-used, and interlinked.

DBCELLS - AN OPEN AND GLOBAL MULTI-SCALE LINKED CELLS

Land change models require large amounts of data, and are diffi cult to be reproduced, as well as to be reused. Some initiatives to open and link data increase the reproducibility of scientifi c experiments and data reuse. One pillar of the linked data concept is the use of Uniform Resource Identifi er (URI). In this paper, we propose DBCells - an architecture for publication of a global cellular space where each cell has a URI. This new approach will allow comparison, reproduction and the reuse of models and data. However, in order to succeed, this proposal requires participation, partnerships and investments. The main purpose of this paper is to present the architecture, benefi ts and challenges for debating with the scientifi c community.

Linked data has been a hot topic in the library world, and this book provides a good overview of the topic. The contributors present theoretical and practical information to help readers understand linked data concepts and its purpose. The first chapter, by Thorson and Pattuelli, presents institutional projects experimenting with linked data, including Europeana, the Digital Public Library of America (DPLA), the Social Networks and Archival Context Project (SNAC), and more. They also present a detailed description of the Linked Jazz project. In the second chapter, Stahmer presents the migration process of the English Short Title Catalogue (ESTC) from MARC to linked data and potential benefits that migration presents. The author provides a great explanation of the triplestore data model, a discussion of tagging and controlled vocabularies, and social cataloging.

The Importance of Identifiers in the New Web Environment and Using the Uniform Resource Identifier (URI) in Subfield Zero ($0): A Small Step That Is Actually a Big Step

While the future of library bibliographic description is currently in a state of flux, libraries have a number of opportunities to begin embedding and leveraging linked data concepts within their existing MARC-centric systems. Through the embedding of dereferenceable Uniform Resource Identifiers (URIs) into existing MARC data, libraries can begin to lay the foundation for the eventual shift to a data model that is more linked data friendly and begin to produce actionable metadata for consumption by services outside of the library community. This article will discuss a pilot project at the George Washington University Libraries to embed URIs into the local integrated library system and the toolset, MARCNext, which was utilized to simplify the entification of the Libraries’ legacy metadata records.

Performance Evaluation of South Esk Hydrological Sensor Web: Unsupervised Machine Learning and Semantic Linked Data Approach

Technological progress has lead the sensor network domain to an era where environmental and agricultural domain applications are completely dependent on hydrological sensor networks. Data from the sensor networks are being used for knowledge management and critical decision support system. The quality of data can, however, vary widely. Existing automated quality assurance approach based on simple threshold rulebase could potentially miss serious errors requiring robust and complex domain knowledge to identify. This paper proposes a linked data concept, unsupervised pattern recognition, and semantic ontologies based dynamic framework to assess the reliability of hydrological sensor network and evaluate the performance of the sensor network. Newly designed framework is used successfully to evaluate the South Esk hydrological sensor web in Tasmania, indicating that domain ontology based linked data approach could be a very useful methodology for quality assurance of the complex data.
