    Expressing the tacit knowledge of a digital library system as linked data

    Library organizations have enthusiastically undertaken semantic web initiatives and in particular the data publishing as linked data. Nevertheless, different surveys report the experimental nature of initiatives and the consumer difficulty in re-using data. These barriers are a hindrance for using linked datasets, as an infrastructure that enhances the library and related information services. This paper presents an approach for encoding, as a Linked Vocabulary, the "tacit" knowledge of the information system that manages the data source. The objective is the improvement of the interpretation process of the linked data meaning of published datasets. We analyzed a digital library system, as a case study, for prototyping the "semantic data management" method, where data and its knowledge are natively managed, taking into account the linked data pillars. The ultimate objective of the semantic data management is to curate the correct consumers' interpretation of data, and to facilitate the proper re-use. The prototype defines the ontological entities representing the knowledge, of the digital library system, that is not stored in the data source, nor in the existing ontologies related to the system's semantics. Thus we present the local ontology and its matching with existing ontologies, Preservation Metadata Implementation Strategies (PREMIS) and Metadata Objects Description Schema (MODS), and we discuss linked data triples prototyped from the legacy relational database, by using the local ontology. We show how the semantic data management, can deal with the inconsistency of system data, and we conclude that a specific change in the system developer mindset, it is necessary for extracting and "codifying" the tacit knowledge, which is necessary to improve the data interpretation process

    Addressing the tacit knowledge of a digital library system

    Recent surveys, about the Linked Data initiatives in library organizations, report the experimental nature of related projects and the difficulty in re-using data to provide improvements of library services. This paper presents an approach for managing data and its "tacit" organizational knowledge, as the originating data context, improving the interpretation of data meaning. By analyzing a Digital Libray system, we prototyped a method for turning data management into a "semantic data management", where local system knowledge is managed as a data, and natively foreseen as a Linked Data. Semantic data management aims to curates the correct consumers' understanding of Linked Datasets, driving to a proper re-use

    Asymmetric Epoxidation: A Twinned Laboratory and Molecular Modeling Experiment for Upper-Level Organic Chemistry Students

    Get PDF
    The coupling of a student experiment involving the preparation and use of a catalyst for the asymmetric epoxidation of an alkene with computational simulations of various properties of the resulting epoxide is set out in the form of a software toolbox from which students select appropriate components. At the core of these are the computational spectroscopic tools, whereby a measured spectrum can be interpreted in some detail using theoretical simulations. These include a range of modern chiroptical methods to accompany the increased use of such techniques in modern teaching laboratories. Computational experiments are captured in a Wiki-based electronic laboratory notebook, which features data-stamping, authenticated entries, and inclusion of semantically intact data via interactive models rendered within the Wiki using JSmol and its referencing via a digital object identifier (DOI) to a digital data repository

    The Neptune Theatre: A Case Study

    Get PDF
    The Neptune Theatre, formerly known as the U-Neptune Theatre, was one of five neighborhood theaters constructed in the University District during the silent film era (1919 - 1921). This period, the 1920s, was “Seattle’s most active decade” of theater construction (Flom, 2001). Today, the Neptune remains as the last standing survivor of those venues still in operation a hundred years later. Still owned by descendants of the original family and now leased and operated by the Seattle Theatre Group (STG), this venue hosts artists and events ranging from David Crosby concerts to a Welcome to Nightvale live podcast performance; from a Macklemore guest appearance (Matson, 2012) to the annual Nights at the Neptune and Youth Speaks series. It remains one of Seattle’s premiere hot spots for concerts, film screenings, spoken word and dance showcases, and performances by touring musical legends and community youth alike. In our current environment of constrained resources, fiscal scrutiny, monotonous modern construction, and a movement towards historical stewardship and adaptive reuse, it is vital to develop a familiarity with exemplary facilities that embody long-term success by exploring and analyzing their leadership, design, operation, maintenance, and capitalization strategies, which have contributed to their ongoing survival and flourishment. By doing so, we can learn ways to extend the functional lifespan of well-maintained, unique, relevant, and community-engaged arts venues

    Multiuser Detection Assisted Time- and Frequency-Domain Spread Multicarrier Code-Division Multiple-Access

    No full text
    In this contribution, we study a reduced-complexity multiuser detection aided multicarrier direct-sequence code-division multiple-access (MC DS-CDMA) scheme, which employs both time (T)-domain and frequency (F)-domain spreading. We investigate the achievable detection performance in the context of synchronous TF-domain spread MC DS-CDMA when communicating over an additive white Gaussian noise (AWGN) channel. Five detection schemes are investigated, which include the single-user correlation based detector, the joint TF-domain decorrelating multiuser detector (MUD), the joint TF-domain MMSEMUD, the separate TF-domain decorrelating/MMSE MUD, and the separate TF-domain MMSE/decorrelating MUD. Our simulation results show that the separate TF-domain MUD schemes are capable of achieving a similar bit error rate (BER) performance to that of the significantly more complex joint TF-domain MUD schemes. Index Terms—Code-division multiple-access (CDMA), decorrelating, frequency-domain spreading, joint detection, minimum mean square error (MMSE), multicarrier (MC), multiuser detection, separate detection, time-domain spreading

    Ingest and Storage of 3D Objects in a Digital Preservation System

    The DURAARK project is developing methods and tools for the Long-Term Preservation (LTP) of architectural knowledge, including approaches to: enrich Building Information Models with “as built” information from scans, semantically enrich building models with additional data sets, preserve 3D models for future reuse. This deliverable defines the necessary steps for ingest and storage of 3D objects into anexisting OAIS compliant digital preservation system. It discusses how the gaps, which were previously identified and presented in deliverable D6.6.1, have been addressed in the DURAARK project so far. Developed methods and tools will be run against the DURAARK test set. Lastly, the existing drafts of the metadata schemas buildm for descriptive information and e57m and ifcm as technical metadata schemas for E57 and IFC respectively, will be extended significantly and presented in a digital preservation context

    Liberating links between datasets using lightweight data publishing: an example using plant names and the taxonomic literature

    Get PDF
    Constructing a biodiversity knowledge graph will require making millions of cross links between diversity entities in different datasets. Researchers trying to bootstrap the growth of the biodiversity knowledge graph by constructing databases of links between these entities lack obvious ways to publish these sets of links. One appealing and lightweight approach is to create a "datasette", a database that is wrapped together with a simple web server that enables users to query the data. Datasettes can be packaged into Docker containers and hosted online with minimal effort. This approach is illustrated using a dataset of links between globally unique identifiers for plant taxonomic namesand identifiers for the taxonomic articles that published those names
