Da "un magnifico errore" a "una comunità d'interazione dinamica". I codici di catalogazione angloamericani e l'evoluzione della catalogazione sociale : Lectio magistralis in Biblioteconomia
No full textLa catalogazione sociale è considerata come una tendenza recente del controllo bibliografico. Questo saggio sostiene invece che il coinvolgimento degli utenti nella descrizione e nell'aggiunta di termini del linguaggio naturale rientra nel processo logico di sviluppo dei codici e degli standard di catalogazione. Il saggio ricostruisce la storia delle regole di catalogazione angloamericane a partire dalla metà dell'Ottocento evidenziando un impegno costante verso la cooperazione. Una collaborazione tra catalogatori professionisti e "catalogatori sociali" sembra una alleanza crescente e positiva
Designing a Metadata-Enabled Namespace for Enhancing Resource Discovery in Knowledge Bases [Version presented at the International Conference]
No full textThe proliferation of digitized resources accessible via Internet and Intranet knowledge bases, and a pressing need to develop more sophisticated tools for the identification and retrieval of electronic resources, both general purpose and domain-specific metadata schemes have assumed a particular prominence. While recent work emanating from the World Wide Web Consortium (W3C) has focused on the Resource Description Framework (RDF), and metadata maps or “crosswalks” have been created to support the interoperability of metadata standards -- thus converting metatags from diverse domains from simply “machine-readable” to “machine-understandable” -- the next iteration, to “human-understandable”, remains a challenge. This apparent gap provides a framework for three-phase research (Howarth, 2000, 1999) to develop a tool which will provide a “human-understandable” front-end search assist to any XML-compliant metadata scheme. Findings from phase one, the analyses and mapping of eight metadata schemes, identify the particular challenges of designing a common “namespace”, populated with element tags which are appropriately descriptive, yet readily understood by a lay searcher, when there is little congruence within, and a high degree of variability across, the metadata schemes under study. Implications for the subsequent design and testing of both the proposed “metalevel ontology” (phase two), and the prototype search assist tool (phase three) are examined
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
Filling in the blanks in RDA or remaining blank? The strange case of FRSAD
No full textThis paper covers the significant developments in subject access in the FR (Functional Requirements) family of models, which underpin RDA (Resource Description and Access), the new cataloguing code intended to replace AACR2. It covers in detail the development of FRSAD (Functional Requirements of Subject Authority Data), which was published in 2009 and explains the differences between it and the earlier FR models. Prior to FRSAD’s appearance Pino Buizza and Mauro Gerrini outlined a potential subject access model for FRBR (Buizza and Guerrini 2002). Tom Delsey, the author of RDA, also examined the problem of adding subject access (Delsey 2005). FRSAD itself seemed to generate little comment when it appeared, despite its subject model which departed from that in previous FR standards. FRSAD proposed a subject model based on ‘thema’ and ‘nomen’, whereby the former, defined as ‘any entity used as the subject of a work’, was represented by the latter, defined as ‘any sign or sequence of signs’. Finally, it is suggested in this paper that the linguistic theory underlying the PRECIS Indexing System might provide an alternative model for developing entities in FRSAD
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
