Functional Requirements for Subject Authority Data (FRSAD) - A Conceptual Model
No full textThe purpose of authority control is to ensure consistency in representing a value - a name of a person, a place name, or a term or code representing a subject - in the elements used as access points in information retrieval. The primary purpose of this study is to produce a framework that will provide a clearly stated and commonly shared understanding of what the subject authority data/record/file aims to provide information about, and the expectation of what such data should achieve in terms of answering user needs. This model is superseded by the 2017 IFLA Library Reference Model: A Conceptual Model for Bibliographic Information (IFLA LRM)

21st century accreditation: Teaching, learning, practice, and competences
Get PDFThe ALA Standards for Accreditation of Master’s Programs in Library and Information Studies has undergone a significant proposed revision to foreground: program learning outcomes; place more emphasis on equity, diversity, and inclusion; eliminate redundancy; and reflect the current institutional context of LIS education and/or the needs of the profession. The revision maintains focus on: systematic planning; program level learning outcomes and curriculum; faculty; students; and infrastructure, through the maturing lens and experiences of 21st century students, educators, employers, and schools. The revised Standards are designed to be flexible enough to support a range of program modalities (primarily in-person, hybrid, primarily online), pedagogies, concentrations, and sizes, while maintaining a professional standard and expectation of program learning outcomes relevant to an evolving and expanding range of career options and opportunities. Whether library and information studies programs exist as faculties, schools, or departments, the Standards were revised to be expansive enough to support the development, implementation, and growth of robust teaching, learning, and research environments tailored to institutional strategic directions and local realities but focused on producing quality education experiences for students through common accreditation expectations. This panel brings together program and Committee on Accreditation representatives to review the aims of the revision, the process and results of the revision consultation process focused mainly within the United States, Canada, and the UK where ALA-accreditation is recognized by the Council on Higher Education Accreditation as the accreditor for the field of library and information studies, the experiences and expectations of external review panels during site visits, and the accreditation experiences of two representative schools. The panel will further explore the implementation of the revised standards, Committee on Accreditation expectations, supports available to programs from the Office of Accreditation, and initial and developing experiences in applying the revised standards. The panel will also invite comments, questions, and observations from attendees
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A RAG Approach for Generating Competency Questions in Ontology Engineering
No full textCompetency question (CQ) formulation is central to several ontology development and evaluation methodologies. Traditionally, the task of crafting these competency questions heavily relies on the effort of domain experts and knowledge engineers which is often time-consuming and labor-intensive. With the emergence of Large Language Models (LLMs), there arises the possibility to automate and enhance this process. Unlike other similar works which use existing ontologies or knowledge graphs as input to LLMs, we present a retrieval-augmented generation (RAG) approach that uses LLMs for the automatic generation of CQs given a set of scientific papers considered to be a domain knowledge base. We investigate its performance and specifically, we study the impact of different number of papers to the RAG and different temperature setting of the LLM. We conduct experiments using GPT-4 on two domain ontology engineering tasks and compare results against ground-truth CQs constructed by domain experts. Empirical assessments on the results, utilizing evaluation metrics (precision and consistency), reveal that compared to zero-shot prompting, adding relevant domain knowledge to the RAG improves the performance of LLMs on generating CQs for concrete ontology engineering tasks.</p

Representation Learning on IoT Knowledge Graphs
No full textIn order to make the large amounts of messages generated by IoT devices in Smart Buildings interoperable, ontologies are used to represent the data as knowledge graphs (KGs). Learning over these IoT KGs can be used for various tasks, such as prediction or classification. Existing methods for KG representation learning are often evaluated on benchmark KGs and it is not explored how such methods perform on IoT KGs. The specific structure of the IoT KGs is likely to influence the quality of the representations. In this study, we investigate how the structure of IoT KGs affects the effectiveness of representation learning methods. Additionally, we look at the effect on representation quality of enriched IoT KGs, with for example temporal sequences or measurement value similarity, and the effect of the size of the IoT KGs. We perform experiments on three IoT KGs, with two representation learning methods (RDF2Vec and GCN) and two evaluation tasks (classification and value prediction). The results show that models trained with representations from enriched KGs outperform models trained with representations from original KGs on the evaluation tasks.(This article is a revised and extended version of [24]. It constitutes a significant extension with regards to the number and scale of experiments, embedding methods and evaluation tasks.)</p
