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
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
Terminology web services
Get PDFControlled terminologies such as classification schemes, name authorities and thesauri have long been the domain of the library and information science community. Although historically there have been initiatives towards library style classification of web resources, there remain significant problems with searching and quality judgement of online content. Terminology services can play a key role in opening up access to these valuable resources. By exposing controlled terminologies via a web service, organisations maintain data integrity and version control, whilst motivating external users to design innovative ways to present and utilise their data. We describe the approaches taken in establishing programmatic API's, then relate our experiences in creating terminology web services and associated client interface components, in particular for the archaeology domain (STAR project) and consider the case for more specialised services for different kinds of controlled vocabular
Vocabulary mapping for archaeological infrastructure
Get PDFThis article reports and reflects on vocabulary mapping techniques, tools and experience from the ARIADNE European archaeological infrastructure projects, where the widely differing terminology of subject indexing in the different partner languages posed significant challenges for effective data integration. The Getty Art & Architecture Thesaurus is employed as a central spine vocabulary for partners to map their native vocabularies and term lists – a hub structure enables a multilingual search capability via vocabulary mapping. Mappings are expressed via SKOS mapping relationships and output as structured JSON for use in the overall data aggregation process and in the ARIADNE portal. The approach followed offers some automatic support for final intellectual judgement. The method can be characterised as providing lexical support in an interactive tool that aims to intuitively visualise semantic context. The experience of partners in producing the vocabulary mappings is discussed in light of previous work in this area. Reflections on lessons learned both for the immediate project and for vocabulary mapping in general contribute to the conclusions. Future search functionality could take account of available vocabulary mappings via a range of search options, such as query expansion including compound mappings and mapping types. Further work on mapping guidelines and metadata is recommended
Reflections on experience with archaeological controlled vocabularies in indexing and retrieval
Get PDFIn the STAR project investigating semantic integration, we employed thesauri from the Forum on Information Standards in Heritage (FISH) and word lists from Historic England recording manuals. Semantic integration allowed search across both archaeological datasets and grey literature reports via data extraction and NLP (Tudhope et al. 2011; Vlachidis & Tudhope 2016). The ARIADNE and ARIADNEplus European Infrastructure projects confronted multi-lingual issues in seeking to integrate archaeological data and reports written (and indexed by CV) in various partner languages. We developed tools to help map partner CVs to a central ‘mapping hub’, the Getty Art and Architecture Thesaurus (AAT), allowing search across partner data and reports in different languages and also query expansion using the AAT’s hierarchical structure (Binding & Tudhope 2016). We have also provided tools to express English, Scottish, Welsh (including Gaelic and Welsh language) FISH vocabularies as Linked Open Data (HeritageData) facilitating programmatic use. We are currently collaborating with the Archaeology Data Service (ADS) on CV based NLP tools to make automatic indexing suggestions for the OASIS online index of fieldwork events and their unpublished reports, drawing on FISH vocabularies (Monuments, Objects, Periods) employed in OASIS subject indexing.Reflections from this experience are discussed. These include the potential of mapping between CVs, possible need for an enhanced entry vocabulary (synonyms etc) in CVs when used in NLP and the challenge of compound phrases that combine concepts, possibly meriting a faceted approach. There may be a need to draw on standard CVs from other domains (eg for scientific areas). It is possible to index with multiple CVs. It is important to consider use cases; the indexing requirements of grey literature may differ from academic journal publishing. CVs should be continually maintained and evolve, alert to potential gaps or bias of different kinds.<br/
