Steps to improving Library Services Through Artificial Intelligence in Nigerian Libraries
No full textLatest technological development in the twenty-first century has brought a dramatic change in every field, and library science is no exception. Like any other fields, Librarianship is also incorporating many fascinating technologies into their armories. This research looked into the conceptual background of artificial intelligence (AI), library services, and the application of AI in library services. The study also reviewed existing literatures on the impact of AI on library services and the extent of its application in Nigeria libraries. The findings show that AI can improve library services like; circulation and reference services, book shelving and shelve reading, cataloguing of library materials, analyzing big data, creating metadata, interpreting search items among others. The research goes on to discuss some of the factors that affect the use of AI in academic libraries such as funding, lack of maintenance, lack of experts in AI, erratic power supply as well as possible strategies to solve the problems: developing policy for AI, consultation, adequate funding, employment of AI experts among others
Expressing Information Needs and Information Literacy Skills Amongst Final Year Undergraduate Students in Northern Nigeria
Get PDFInformation literacy is the ability of an individual to locate, evaluate, and use information. This study expresses the conscious information needs and information literacy skills amongst final year undergraduate students of three Universities in Nigeria; being the Ahmadu Bello University (ABU), Federal University Lokoja (FUL), and Baze University. A survey research design alongside a questionnaire for the instrument were utilised on a sample size of 307 final year undergraduate students from select faculties within the above-mentioned universities. The findings of the study amongst other show that undergraduate students at the final year level had a conscious knowledge of their information needs, while their ability to locate information was heavily reliant on the use of the Internet. Other finding of the study revealed that the student’s skill level in regard evaluation of information and information sources was low. At a time when there is prevalent use of the internet by netizens and online publishing is at an all-time high. The study further recommends teaching critical reasoning and how to evaluate information sources by schools as a means of improving information need identification by students and literacy skills. The study concludes on the importance of students being conscious of their information need and schools emphasizing and building programs for information literacy skills acquisition
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
Library Literacy: Its role on the Usage of Libraries and Information Resources
Get PDFThe paper highlights the dearth of library usage as a result of a lacking library literacy particularly amongst second year business education students. To examine and better understand the problem, the paper adopted three research questions; the study adopted a survey research design. The population for the study comprised of second year business education students of the faculty of education which was randomly sampled. A questionnaire was chosen as the research instrument and used to solicit answers to the research questions. The findings indicate that the level of library literacy obtained by these second-year University students indeed attributed to the low use of libraries
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
