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
Annoteringsverktøyet TORCH - Brukskvalitetstesting av et annoteringsverktøy
No full textI denne masteroppgaven presenteres resultatene fra en brukskvalitetsevaluering av et annoteringsverktøy utviklet i forbindelse med TORCH-prosjektet ved Høgskolen i Oslo og Akershus. Det ble gjennomført to brukertester med formål å legge til rette for crowdsourcing av annotering av navneentiteter og relasjoner. Interessante problemer og bruksmønstre fra eksisterende litteratur manifesterte seg i undersøkelsene. Til tross for svakheter funnet i grensesnittet til versjonene av verktøyet som ble brukt i forsøkene, viste annotørene en rimelig suksessrate. I tillegg til brukskvalitetsproblemene som ble avdekket, ble det konkludert med to ting: brukerne med rimelige datakunnskaper presterte godt, og det ble ikke funnet noen klar sammenheng mellom hvor vanskelig brukerne opplevde en oppgave og deres interesse i å delta i senere prosjekter med lignende aktiviteter
Accessibility and provision of digital library resources to the visually impaired students in academic libraries: A case study of University of Oslo Library
No full textThe study explored the accessibility and provision of digital library resources to the visually impaired (VI) students in academic libraries, and it used the library of university of Oslo as a case institution. This study sought to gather data about the visually impaired students‟ experiences in accessing digital library resources on the one hand, while on the other, the library staff‟s experiences in serving these students. By gathering data directly from real users (students) of the digital library resources / services, and the facilitators (library staff), the study intended to contribute to an understanding of, and help inform improved service delivery in this area.
The study sample comprised six (6) respondents. Four (4) visually impaired students (one PhD and three Master‟s programme students). These were considered to have experience of using digital library resources during the period of doing course requirements including examinations and also during the time of conducting research and writing their theses. Two (2) library staff of the University of Oslo were also part of the sample. One was directly involved in serving the visually impaired students while the other works in the department of providing digital library services. Student respondents were selected by use of snowball sampling technique while the library staff were purposively selected. The study employed a qualitative research design, and data was collected by use of in-depth interviews.
The study was premised in the models of disability - medical and social model but much emphasis was put on the social model which seemed more relevant in explaining the phenomenon under study.
Findings indicate that the visually impaired students largely depend on intermediaries like library staff, fellow students, friends, and reading assistants to access the digital library resources. However, findings indicate that majority of the student respondents are not satisfied with the assistance from intermediaries especially the library staff, although some of the respondents expressed some appreciation of the assistance they receive from these intermediaries. Furthermore, because the university does not adequately guarantee full access to the digital resources, it was found out that the visually impaired students seek for study literature and digital resources from other alternative sources notably, the Norwegian Library for talking books and Braille (NLB), Google scholar and Huseby resource center. The study findings however, indicate that these alternative sources do not also meet most of the information needs of the visually impaired students.
Nevertheless, the study findings indicate benefits the visually impaired students have gained from accessing the digital library resources. Findings also indicate various challenges/obstacles faced by the visually impaired students to access digital library services as well as challenges faced by the library staff to provide digital library services to the visually impaired students. Obstacles identified include; the design of the library interface, document format delivery, administrative challenge, lack of competence, inadequate library facilities and staff services, work overload, among others,
By looking into the highlighted obstacles faced by both students the situation of the VI will likely to be improved

The experiments employed non-experts with the intention of facilitating for crowdsourcing of named entity annotation. Interesting problems and usability patterns from existing literature manifest in the experiments. Despite some weaknesses in the interface of the tool versions used for the experiments, the annotators showed a reasonable rate of success. In addition to the usability issues discovered, it was found that users with reasonable computer skills performed well, and there was no clear connection between how hard the users found a task and their interest in participating in further projects with similar activities.acceptedVersio
Metadata Practices for Digital Photographic Collections in Archives, Libraries, and Museums in Norway
No full textThis thesis aims to explore the current state of metadata practices for digital photographic
collections in archives, libraries, and museums in Norway in terms of the awareness of
metadata and metadata types, the availability of guidelines, the chief source of information
on cataloging digital photographic items, the metadata scheme used, subject cataloging
standards and the opinions of staff on the problems and factors regarding cataloging digital
photographic collections.
A descriptive survey is used as the research method. Data was collected by using an online
questionnaire. A survey link was distributed to archives, libraries, and museums in Norway
which have digital photographic collection projects. A total of 45 returned questionnaires
were analyzed into descriptive statistics by using the Statistical Package for the Social
Sciences (SPSS) program
The findings indicate that most of the responding memory institutions have guidelines for
cataloging digital photographic collections available at their workplaces (in print format
more often than digital format). In the opinion of respondents, cataloging digital
photographic materials is similar to cataloging photographs in other formats. Further,
metadata is very important for organizing digital collections in their perspective. The
Standard for Fotokatalogisering is the most adopted metadata scheme for digital
photographic collections and responding memory institutions assign free keywords more
often than using standardized subject heading lists. For the most part, the respondents
agree that the mandatory elements in the Standard for Fotokatalogisering are the most
important.
Considering problems facing the digital collection projects of responding institutions, an
insufficient budget is the most problematic, with the highest mean response. Inadequate
existing data on the materials and a high demand for specialized knowledge and skills also
greatly challenge them. As future challenges facing such projects, respondents most
frequently point out user needs, policies on digital photographic collection development,
and technology. Respondents highlight knowledge, skills and work resources as their
potential contributions of institutions to collaborative projects
