A linked data approach to publishing complex scientific workflows

Past data management practices in many fields of natural science, including climate research, have focused primarily on the final research output - the research publication - with less attention paid to the chain of intermediate data results and their associated metadata, including provenance. Data were often regarded merely as an adjunct to the publication, rather than a scientific resource in their own right. In this paper, we attempt to address the issues of capturing and publishing detailed workflows associated with the climate/research datasets held by the Climatic Research Unit (CRU) at the University of East Anglia. To this end, we present a customisable approach to exposing climate research workflows for the effective re-use of the associated data, through the adoption of linked-data principles, existing widely adopted citation techniques (Digital Object Identifier) and data exchange mechanisms (Open Archives Initiative Object Reuse and Exchange)

Data semantic enrichment for complex event processing over IoT Data Streams

This thesis generalizes techniques for processing IoT data streams, semantically enrich data with contextual information, as well as complex event processing in IoT applications. A case study for ECG anomaly detection and signal classification was conducted to validate the knowledge foundation

“Not for Casual Readers:” An Evaluation of Digital Data from Virginia Archaeological Websites

Archaeological data dissemination is complicated by the need to serve disparate audiences, each of which has different data needs. This study examined the websites of 148 Virginia institutions identified as having archaeological collections or data, and used content analysis to see how they supported characteristics of scholarly publishing, open data and public outreach. Archaeologists are increasingly looking for comparative data sets for research needs, with professional ethics and a desire for public engagement encouraging data sharing. However this analysis suggests that, while there are some exemplary websites, much of the archaeological record remains publicly inaccessible. The majority of websites examined provided no reference to archaeology and, of the remainder, a third did not provide archaeological data. These websites did provide many supporting characteristics for public outreach, but concerns about preservation, data “openness,” and limited datasets remain

Preserving today for tomorrow: a case study of an archive of Interactive Music Installations

Περιέχει το πλήρες κείμενοThis work presents the problems addressed and the first results obtained by a project aimed at the preservation of Interactive Music Installations (IMI). Preservation requires that besides all the necessary components for the (re)production of a performance, also the knowledge about these components is kept, so that the original process can be repeated at any given time. This work proposes a multilevel approach for the preservation of IMI. As case studies, the Pinocchio Square (installed in EXPO 2002) and the Il Caos delle Sfere are considered

Access to recorded interviews: A research agenda

Recorded interviews form a rich basis for scholarly inquiry. Examples include oral histories, community memory projects, and interviews conducted for broadcast media. Emerging technologies offer the potential to radically transform the way in which recorded interviews are made accessible, but this vision will demand substantial investments from a broad range of research communities. This article reviews the present state of practice for making recorded interviews available and the state-of-the-art for key component technologies. A large number of important research issues are identified, and from that set of issues, a coherent research agenda is proposed

Calidad en repositorios digitales en Argentina, estudio comparativo y cualitativo

Numerous institutions and organizations need not only to preserve the material and publications they produce, but also have as their task (although it would be desirable it was an obligation) to publish, disseminate and make publicly available all the results of the research and any other scientific/academic material. The Open Archives Initiative (OAI) and the introduction of Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), make this task much easier. The main objective of this work is to make a comparative and qualitative study of the data -metadata specifically- contained in the whole set of Argentine repositories listed in the ROAR portal, focusing on the functional perspective of the quality of this metadata. Another objective is to offer an overview of the status of these repositories, in an attempt to detect common failures and errors institutions incur when storing the metadata of the resources contained in these repositories, and thus be able to suggest measures to be able to improve the load and further retrieval processes. It was found that the eight most used Dublin Core fields are: identifier, type, title, date, subject, creator, language and description. Not all repositories fill all the fields, and the lack of normalization, or the excessive use of fields like language, type, format and subject is somewhat striking, and in some cases even alarmingComment: BIREDIAL-ISTEC 2017, in Spanis
