  Parapar, J. ; Losada, D.E. ; Presedo-Quindimil, M.A. ; Barreiro, A.: Using score distributions to compare statistical significance tests for information retrieval evaluation.
  In: Journal of the Association for Information Science and Technology. 71(2020) no.1, S.98-113.
  
  Abstract: Statistical significance tests can provide evidence that the observed difference in performance between 2 methods is not due to chance. In information retrieval (IR), some studies have examined the validity and suitability of such tests for comparing search systems. We argue here that current methods for assessing the reliability of statistical tests suffer from some methodological weaknesses, and we propose a novel way to study significance tests for retrieval evaluation. Using Score Distributions, we model the output of multiple search systems, produce simulated search results from such models, and compare them using various significance tests. A key strength of this approach is that we assess statistical tests under perfect knowledge about the truth or falseness of the null hypothesis. This new method for studying the power of significance tests in IR evaluation is formal and innovative. Following this type of analysis, we found that both the sign test and Wilcoxon signed test have more power than the permutation test and the t-test. The sign test and Wilcoxon signed test also have good behavior in terms of type I errors. The bootstrap test shows few type I errors, but it has less power than the other methods tested.

  Losada, D.E. ; Parapar, J. ; Barreiro, A.: When to stop making relevance judgments? : a study of stopping methods for building information retrieval test collections.
  In: Journal of the Association for Information Science and Technology. 70(2019) no.1, S.49-60.
  
  Abstract: In information retrieval evaluation, pooling is a well-known technique to extract a sample of documents to be assessed for relevance. Given the pooled documents, a number of studies have proposed different prioritization methods to adjudicate documents for judgment. These methods follow different strategies to reduce the assessment effort. However, there is no clear guidance on how many relevance judgments are required for creating a reliable test collection. In this article we investigate and further develop methods to determine when to stop making relevance judgments. We propose a highly diversified set of stopping methods and provide a comprehensive analysis of the usefulness of the resulting test collections. Some of the stopping methods introduced here combine innovative estimates of recall with time series models used in Financial Trading. Experimental results on several representative collections show that some stopping methods can reduce up to 95% of the assessment effort and still produce a robust test collection. We demonstrate that the reduced set of judgments can be reliably employed to compare search systems using disparate effectiveness metrics such as Average Precision, NDCG, P@100, and Rank Biased Precision. With all these measures, the correlations found between full pool rankings and reduced pool rankings is very high.

  Yaco, S. ; Ramaprasad, A.: Informatics for cultural heritage instruction : an ontological framework.
  In: Journal of documentation. 75(2019) no.2, S.230-246.
  
  Abstract: Purpose The purpose of this paper is to suggest a framework that creates a common language to enhance the connection between the domains of cultural heritage (CH) artifacts and instruction. Design/methodology/approach The CH and instruction domains are logically deconstructed into dimensions of functions, semiotics, CH, teaching/instructional materials, agents and outcomes. The elements within those dimensions can be concatenated to create natural-English sentences that describe aspects of the problem domain. Findings The framework is valid using traditional social sciences content, semantic, practical and systemic validity constructs. Research limitations/implications The framework can be used to map current research literature to discover areas of heavy, light and no research. Originality/value The framework provides a new way for CH and education stakeholders to describe and visualize the problem domain, which could allow for significant enhancements of each. Better understanding the problem domain would serve to enhance instruction informed from collections and vice versa. The educational process would have more depth due to better access to primary sources. Increased use of collections would reveal more ways through which they could be used in instruction. The framework can help visualize the past and present of the domain, and envisage its future.

  Karaulova, M. ; Gök, A. ; Shapira, P.: Identifying author heritage using surname data : an application for Russian surnames.
  In: Journal of the Association for Information Science and Technology. 70(2019) no.5, S.488-498.
  
  Abstract: This research article puts forward a method to identify the national heritage of authors based on the morphology of their surnames. Most studies in the field use variants of dictionary-based surname methods to identify ethnic communities, an approach that suffers from methodological limitations. Using the public file of ORCID (Open Researcher and Contributor ID) identifiers in 2015, we developed a surname-based identification method and applied it to infer Russian heritage from suffix-based morphological regularities. The method was developed conceptually and tested in an undersampled control set. Identification based on surname morphology was then complemented by using first-name data to eliminate false-positive results. The method achieved 98% precision and 94% recall rates-superior to most other methods that use name data. The procedure can be adapted to identify the heritage of a variety of national groups with morphologically regular naming traditions. We elaborate on how the method can be employed to overcome long-standing limitations of using name data in bibliometric datasets. This identification method can contribute to advancing research in scientific mobility and migration, patenting by certain groups, publishing and collaboration, transnational and scientific diaspora links, and the effects of diversity on the innovative performance of organizations, regions, and countries.

  Çapulcu Redaktionskollektiv: DELETE! : Digitalisierte Fremdbestimmung.
  Münster : Unrast, 2019. 169 S.
  ISBN 978-3-89771-258-4
  
  Abstract: Das çapulcu redaktionskollektiv untersucht in DELETE! die aktuelle Transformation des Kapitalismus - und damit auch der Machtverhältnisse - durch den >technologischen Angriff<. Der Einfluss der Tech-Giganten auf die Ökonomisierung der entlegensten Lebensbereiche nimmt stetig zu, während klassische politische Institutionen an Bedeutung verlieren. Soziale Punktesysteme verlängern mit ihrem permanenten >Rating< und >Scoring< die Reichweite der lenkenden Disziplinierung weit über die direkte Ausbeutung im Arbeitsverhältnis hinaus. Doch mit welchen Methoden und Zukunftsvisionen überformen Unternehmen wie Facebook, Google, Amazon & Co. unsere Kommunikation und unser Denken? Wie verändern sich angesichts einer zunehmend digitalisierten Fremdbestimmung die Bedingungen für Autonomie und soziale Revolte? Und wie lässt sich die beabsichtigte Vereinzelung und Entsolidarisierung bekämpfen? Im Zentrum des Buches steht erneut die Selbstbehauptung, also der vielfältige Widerstand gegen den umfassenden technologischen Angriff unserer Zeit. »Dabei fällen wir nicht«, so die Autor*innen, »das lächerliche Urteil, dass Technologie grundsätzlich >schlecht< ist. Aus welcher - ohnehin historisch bedingten - Ethik heraus sollten wir das auch tun? Wir sagen, sie ist Gewalt und sozialer Krieg. Unsere Kritik richtet sich deshalb vielmehr gegen die technologische Aneignung von Lebensprozessen.«

  In: Journal of documentation. 75(2019) no.5, S.954-976.
  
  Abstract: Purpose An overview of the current use of handwritten text recognition (HTR) on archival manuscript material, as provided by the EU H2020 funded Transkribus platform. It explains HTR, demonstrates Transkribus, gives examples of use cases, highlights the affect HTR may have on scholarship, and evidences this turning point of the advanced use of digitised heritage content. The paper aims to discuss these issues. Design/methodology/approach This paper adopts a case study approach, using the development and delivery of the one openly available HTR platform for manuscript material. Findings Transkribus has demonstrated that HTR is now a useable technology that can be employed in conjunction with mass digitisation to generate accurate transcripts of archival material. Use cases are demonstrated, and a cooperative model is suggested as a way to ensure sustainability and scaling of the platform. However, funding and resourcing issues are identified. Research limitations/implications The paper presents results from projects: further user studies could be undertaken involving interviews, surveys, etc. Practical implications Only HTR provided via Transkribus is covered: however, this is the only publicly available platform for HTR on individual collections of historical documents at time of writing and it represents the current state-of-the-art in this field. Social implications The increased access to information contained within historical texts has the potential to be transformational for both institutions and individuals. Originality/value This is the first published overview of how HTR is used by a wide archival studies community, reporting and showcasing current application of handwriting technology in the cultural heritage sector.

  Chen, H. ; Baptista Nunes, J.M. ; Ragsdell, G. ; An, X.: Somatic and cultural knowledge : drivers of a habitus-driven model of tacit knowledge acquisition.
  In: Journal of documentation. 75(2019) no.5, S.927-953.
  
  Abstract: The purpose of this paper is to identify and explain the role of individual learning and development in acquiring tacit knowledge in the context of the inexorable and intense continuous change (technological and otherwise) that characterizes our society today, and also to investigate the software (SW) sector, which is at the core of contemporary continuous change and is a paradigm of effective and intrinsic knowledge sharing (KS). This makes the SW sector unique and different from others where KS is so hard to implement. Design/methodology/approach The study employed an inductive qualitative approach based on a multi-case study approach, composed of three successful SW companies in China. These companies are representative of the fabric of the sector, namely a small- and medium-sized enterprise, a large private company and a large state-owned enterprise. The fieldwork included 44 participants who were interviewed using a semi-structured script. The interview data were coded and interpreted following the Straussian grounded theory pattern of open coding, axial coding and selective coding. The process of interviewing was stopped when theoretical saturation was achieved after a careful process of theoretical sampling. ; Findings The findings of this research suggest that individual learning and development are deemed to be the fundamental feature for professional success and survival in the continuously changing environment of the SW industry today. However, individual learning was described by the participants as much more than a mere individual process. It involves a collective and participatory effort within the organization and the sector as a whole, and a KS process that transcends organizational, cultural and national borders. Individuals in particular are mostly motivated by the pressing need to face and adapt to the dynamic and changeable environments of today's digital society that is led by the sector. Software practitioners are continuously in need of learning, refreshing and accumulating tacit knowledge, partly because it is required by their companies, but also due to a sound awareness of continuous technical and technological changes that seem only to increase with the advances of information technology. This led to a clear theoretical understanding that the continuous change that faces the sector has led to individual acquisition of culture and somatic knowledge that in turn lay the foundation for not only the awareness of the need for continuous individual professional development but also for the creation of habitus related to KS and continuous learning. Originality/value The study reported in this paper shows that there is a theoretical link between the existence of conducive organizational and sector-wide somatic and cultural knowledge, and the success of KS practices that lead to individual learning and development. Therefore, the theory proposed suggests that somatic and cultural knowledge are crucial drivers for the creation of habitus of individual tacit knowledge acquisition. The paper further proposes a habitus-driven individual development (HDID) Theoretical Model that can be of use to both academics and practitioners interested in fostering and developing processes of KS and individual development in knowledge-intensive organizations.

  In: Cataloging and classification quarterly. 57(2019) no.5, S.278-308.
  
  Abstract: Semantic interoperability between Resource Description and Access (RDA) and BIBFRAME models is of great interest to the library community. In this context, this work investigates the mapping of core entities, inherent and derivative relationships from RDA to BIBFRAME, and proposes mapping rules assessed using two gold datasets. Findings indicate that RDA core entities and inherent relationships can be successfully mapped to BIBFRAME using the bf:hasExpression property, while extending bf:hasExpression as transitive simplifies BIBFRAME representations. Moreover, mapping derivative relationships between RDA Expressions was successful with loss of specificity in non-translation cases. The mapping of derivative relationships between RDA Works produced "noisy" bf:hasDerivative occurrences in BIBFRAME.

  Harviainen, J.T. ; Rapp, A.: Multiplayer online role-playing as information retrieval and system use : an ethnographic study.
  In: Journal of documentation. 74(2018) no.3, S.624-640.
  
  Abstract: Purpose The purpose of this paper is to expand the research of games as information systems. It illustrates how significant parts of massively multiplayer online role-playing function like information retrieval from a library database system. Design/methodology/approach By combining ideas from earlier contributions on the topics of game environments as information systems, the paper explores how gameplay connects to information retrieval, restricted content access, and information system structure. The paper then proceeds to examine this idea through an ethnographic study conducted in World of Warcraft during 2012-2016. Findings By discussing how multiplayer digital game play is a form of information retrieval, the paper shows that players enjoy the well-restricted access to information that is a constitutive element of gameplay. Examining controlled access, procedural literacies and emphatic keywords, the paper finds that content relevances and system use may be influenced by hedonic concerns rather than task efficiency. Originality/value The study of retrieval issues related to gaming enriches our knowledge on inferences in retrieval. It shows that people may prefer that their access to information be limited, in order to make system use more interesting.

  Zhao, D. ; Strotmann, A. ; Cappello, A.: In-text function of author self-citations : implications for research evaluation practice.
  In: Journal of the Association for Information Science and Technology. 69(2018) no.7, S.949-952.
  (Brief communication)
  
  Abstract: Author self-citations were examined as to their function, frequency, and location in the full text of research articles and compared with external citations. Function analysis was based on manual coding of a small dataset in the field of library and information studies, whereas the analyses by frequency and location used both this small dataset and a large dataset from PubMed Central. Strong evidence was found that self-citations appear more likely to serve as substantial citations in a text than do external citations. This finding challenges previous studies that assumed that self-citations should be discounted or even removed and suggests that self-citations should be given more weight in citation analysis, if anything.

  Rapp, F. ; Kombrink, S. ; Kushnarenko, V. ; Fratz, M. ; Scharon, D.: SARA-Dienst : Software langfristig verfügbar machen.
  In: o-bib: Das offene Bibliotheksjournal. 5(2018) Nr.2, S.92-105.
  
  Abstract: Software spielt in vielen Disziplinen eine wichtige Rolle im Forschungsprozess. Sie ist entweder selbst Gegenstand der Forschung oder wird als Hilfsmittel zur Erfassung, Verarbeitung und Analyse von Forschungsdaten eingesetzt. Zur Nachvollziehbarkeit der durchgeführten Forschung sollte Software langfristig verfügbar gemacht werden. Im SARA-Projekt zwischen der Universität Konstanz und der Universität Ulm wird ein Dienst entwickelt, der versucht die Einschränkungen bereits bestehender Angebote aufzuheben. Dies beinhaltet u.a. die Möglichkeit, die gesamte Entwicklungshistorie auf einfache Weise mitzuveröffentlichen und für Dritte zur Online-Exploration anzubieten. Zudem bestimmen die Forschenden den Zeitpunkt und Umfang der zu archivierenden/veröffentlichenden Software-Artefakte selbst. Der SARA-Dienst sieht auch die Möglichkeit vor, eine Archivierung ohne Veröffentlichung vorzunehmen. Der geplante Dienst verbindet bereits bestehende Publikations- und Forschungsinfrastrukturen miteinander. Er ermöglicht aus der Arbeitsumgebung der Forschenden heraus eine Archivierung und Veröffentlichung von Software und unterstützt Forschende dabei, bereits prozessbegleitend Zwischenstände ihrer Forschung festzuhalten. Aufgrund seines modularen Aufbaus kann der SARA-Dienst in unterschiedlichen Szenarien zum Einsatz kommen, beispielsweise als kooperativer Dienst für mehrere Einrichtungen. Er stellt eine sinnvolle Ergänzung zu bestehenden Angeboten im Forschungsdatenmanagement dar.

  In: o-bib: Das offene Bibliotheksjournal. 5(2018) Nr.4, S.166-169.
  
  Abstract: Welche Kenntnisse und Fähigkeiten sollen Hochschulen und Ausbildungseinrichtungen zukünftigen Bibliothekarinnen und Bibliothekaren im Aufgabenfeld der Förderung von Informationskompetenz vermitteln? Diese Frage beschäftigt die Lehrenden der verschiedenen Einrichtungen, die ihre Absolventinnen und Absolventen möglichst optimal auf die aktuellen und zukünftigen Anforderungen der Praxis vorbereiten wollen. Vor diesem Hintergrund stellt der Beitrag ein Konzept für ein "Framework" vor, das es zum einen leisten soll, die grundlegenden Gemeinsamkeiten in den Anforderungen an die Kenntnisse und Fähigkeiten von Bibliothekarinnen und Bibliothekaren aller Qualifikationsstufen im Aufgabenbereich "Förderung von Informationskompetenz" abzubilden und das zum anderen eine bedarfsbezogene Ausprägung und Gewichtung von Qualifikationszielen in den verschiedenen Studiengängen und Ausbildungseinrichtungen ermöglicht. Die diskursive Weiterentwicklung des Frameworks "Informationskompetenz" im Rahmen verschiedener Veranstaltungen auf dem Bibliothekartag 2018 führt weiter zu der Überlegung, auch für andere bibliothekarische Aufgabenbereiche entsprechende Frameworks zu entwickeln und damit eine flexible und zukunftsfähige Gestaltung bibliotheks- und informationswissenschaftlicher Curricula zu unterstützen.

  Abstract: This contribution discusses the notion of an "ideal" language and its implications for the development of knowledge organisation theory. We explore the notion of an ideal language from both a historical and a formal perspective and seek to clarify the key concepts involved. An overview of some of the momentous attempts to produce an ideal language is combined with an elucidation of the consequences the idea had in modern thought. We reveal the possibilities that the idea opened up and go into some detail to explain the theoretical boundaries it ran into.

  Hubert, G. ; Pitarch, Y. ; Pinel-Sauvagnat, K. ; Tournier, R. ; Laporte, L.: TournaRank : when retrieval becomes document competition.
  In: Information processing and management. 54(2018) no.2, S.252-272.
  
  Abstract: Numerous feature-based models have been recently proposed by the information retrieval community. The capability of features to express different relevance facets (query- or document-dependent) can explain such a success story. Such models are most of the time supervised, thus requiring a learning phase. To leverage the advantages of feature-based representations of documents, we propose TournaRank, an unsupervised approach inspired by real-life game and sport competition principles. Documents compete against each other in tournaments using features as evidences of relevance. Tournaments are modeled as a sequence of matches, which involve pairs of documents playing in turn their features. Once a tournament is ended, documents are ranked according to their number of won matches during the tournament. This principle is generic since it can be applied to any collection type. It also provides great flexibility since different alternatives can be considered by changing the tournament type, the match rules, the feature set, or the strategies adopted by documents during matches. TournaRank was experimented on several collections to evaluate our model in different contexts and to compare it with related approaches such as Learning To Rank and fusion ones: the TREC Robust2004 collection for homogeneous documents, the TREC Web2014 (ClueWeb12) collection for heterogeneous web documents, and the LETOR3.0 collection for comparison with supervised feature-based models.

  In: Cataloging and classification quarterly. 56(2018) no.4, S.354-373.
  
  Abstract: This article discusses and highlights alignment issues that arise between UNIMARC Authorities Format and Resource Description and Access (RDA) regarding the creation of name and title authorities for musical works and creators. More specifically, RDA, as an implementation of the FRAD model, is compared with the UNIMARC Authorities Format (Updates 2012 and 2016) in an effort to highlight various cases where the discovery of equivalent fields between the two standards is not obvious. The study is envisioned as a first step in an ongoing process of working with the UNIMARC community throughout RDA's advancement and progression regarding the entities [musical] Work and Names.
