Abstract

In recent years, cultural heritage institutions have been exploring the benefits of applying Linked Open Data to their catalogs and digital materials. Innovative and creative methods have emerged to publish and reuse digital contents to promote computational access, such as the concepts of Labs and Collections as Data. Data quality has become a requirement for researchers and training methods based on artificial intelligence and machine learning. This article explores how the quality of Linked Open Data made available by cultural heritage institutions can be automatically assessed. The results obtained can be useful for other institutions who wish to publish and assess their collections.

Abstract

This study is an attempt to assess the potential for automatic vocabulary switching from a thesaurus to LCSH. Terms from the 'Laborline Thesaurus' were manually mapped to LCSH, with the degree of match indicated by a code from 1 to 19, representing the nature of the match from exact match to no match. Am INMAGIC database for the amp was created in order to permit analysis of the aptterns of matches to see whether there were regularities that could be exploited to improve the performance of switching interfaces. Searches of the database by match codes reveal ranges of 21,98% for no matches to 0,06% for translation matches, with 16,3% for exact matches. It is estimated that a maximum of 61%, but a more realistic figure of 41,5%, of the terms coulc be successfully switched automatically using currently proposed or available strategies. As long as LCSH is used for subject descriptions in online catalogs, it would appear that intelligent interfaces for vocabulary switching can only be partially successful, and it is suggested that manual mapping, while labor-intensive, is a feasible alternative

Abstract

The FRSAD model provides an abstract analysis of subject authority data. The article tries to assess the compatibility of this conceptual framework with formalisms and practices that have emerged from the Semantic Web community. Through applying SKOS, it becomes apparent that some interpretive decisions necessary to accommodate the rigor of formal knowledge representation languages are not supported by FRSAD itself. Difficulties in clearly aligning the thema entity with either a SKOS or OWL counterpart reveal ambiguities in the FRSAD model regarding the ontological status of thema, which seems to reflect a general uncertainty regarding the aboutness of subject authority data in the library domain.

Abstract

Purpose - The purpose of this paper is to provide a clear image of the information architecture used in the Encyclopedia of Iranian Architectural History (EIAH) and to show how it was crafted to meet the need for accessibility, expressiveness and interoperability. Design/methodology/approach - In order to assess the level of interoperability in the system, two essential concepts of the system are identified and traced in every level of the three-layer information architecture. Federated repositories are studied for the level of accessibility that they can offer. Knowledge representation level, mediator level and the semantic portal are studied for expressiveness capabilities. Findings - EIAH information architecture is capable of establishing links among resources available in the information pools connected to the system by using EIAH metadata application profile (EMAP). Different modules in this architecture, which are localized for the Persian language, can work on similar environments for other languages, for example Arabic. Originality/value - EIAH is the first example of a digital encyclopedia for the history of Iranian architecture, which is basically different from other digital encyclopedias in the way that it offers information to users. EIAH is aimed at domain experts and provides them not with pre-written and quality articles but with a wide range of resources and documents relative to what they are seeking.

Abstract

This highly practical handbook teaches you how to unlock the value of your existing metadata through cleaning, reconciliation, enrichment and linking and how to streamline the process of new metadata creation. Libraries, archives and museums are facing up to the challenge of providing access to fast growing collections whilst managing cuts to budgets. Key to this is the creation, linking and publishing of good quality metadata as Linked Data that will allow their collections to be discovered, accessed and disseminated in a sustainable manner. This highly practical handbook teaches you how to unlock the value of your existing metadata through cleaning, reconciliation, enrichment and linking and how to streamline the process of new metadata creation. Metadata experts Seth van Hooland and Ruben Verborgh introduce the key concepts of metadata standards and Linked Data and how they can be practically applied to existing metadata, giving readers the tools and understanding to achieve maximum results with limited resources. Readers will learn how to critically assess and use (semi-)automated methods of managing metadata through hands-on exercises within the book and on the accompanying website. Each chapter is built around a case study from institutions around the world, demonstrating how freely available tools are being successfully used in different metadata contexts. This handbook delivers the necessary conceptual and practical understanding to empower practitioners to make the right decisions when making their organisations resources accessible on the Web. Key topics include, the value of metadata; metadata creation - architecture, data models and standards; metadata cleaning; metadata reconciliation; metadata enrichment through Linked Data and named-entity recognition; importing and exporting metadata; ensuring a sustainable publishing model. This will be an invaluable guide for metadata practitioners and researchers within all cultural heritage contexts, from library cataloguers and archivists to museum curatorial staff. It will also be of interest to students and academics within information science and digital humanities fields. IT managers with responsibility for information systems, as well as strategy heads and budget holders, at cultural heritage organisations, will find this a valuable decision-making aid.

Abstract

This PhD-thesis describes how to effectively explore linked data on the Web. The main focus is on scenarios where users want to discover relationships between resources rather than finding out more about something specific. Searching for a specific document or piece of information fits in the theoretical framework of information retrieval and is associated with exploratory search. Exploratory search goes beyond 'looking up something' when users are seeking more detailed understanding, further investigation or navigation of the initial search results. The ideas behind exploratory search and querying linked data merge when it comes to the way knowledge is represented and indexed by machines - how data is structured and stored for optimal searchability. Queries and information should be aligned to facilitate that searches also reveal connections between results. This implies that they take into account the same semantic entities, relevant at that moment. To realize this, we research three techniques that are evaluated one by one in an experimental set-up to assess how well they succeed in their goals. In the end, the techniques are applied to a practical use case that focuses on forming a bridge between the Web and the use of digital libraries in scientific research. Our first technique focuses on the interactive visualization of search results. Linked data resources can be brought in relation with each other at will. This leads to complex and diverse graphs structures. Our technique facilitates navigation and supports a workflow starting from a broad overview on the data and allows narrowing down until the desired level of detail to then broaden again. To validate the flow, two visualizations where implemented and presented to test-users. The users judged the usability of the visualizations, how the visualizations fit in the workflow and to which degree their features seemed useful for the exploration of linked data.

Abstract

Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

Abstract

This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.
