Graf, K.: Großer Suchmaschinentest 2021 : Alternativen zu Google?.
In: https://archivalia.hypotheses.org/129466.

Abstract: Weg von Google: Die besten Suchmaschinen-Alternativen, lautet der Titel eines Artikels im Standard. Und wieder ist meine Antwort, dass es dumm und töricht wäre, für wissenschaftliche Zwecke auf eine Google-Direktabfrage zu verzichten. Insbesondere die Einbindung von Ergebnissen aus Google Books, zu dem man direkt wechseln kann, und Google Scholar, macht die Google Websuche unverzichtbar.

Steeg, F. ; Pohl, A.: ¬Ein Protokoll für den Datenabgleich im Web am Beispiel von OpenRefine und der Gemeinsamen Normdatei (GND).
In: Qualität in der Inhaltserschließung. Hrsg.: M. Franke-Maier, u.a. München : DeGruyter-Saur, 2021. S.259-278.
(Bibliotheks- und Informationspraxis; 70)

Abstract: Normdaten spielen speziell im Hinblick auf die Qualität der Inhaltserschließung bibliografischer und archivalischer Ressourcen eine wichtige Rolle. Ein konkretes Ziel der Inhaltserschließung ist z. B., dass alle Werke über Hermann Hesse einheitlich zu finden sind. Hier bieten Normdaten eine Lösung, indem z. B. bei der Erschließung einheitlich die GND-Nummer 11855042X für Hermann Hesse verwendet wird. Das Ergebnis ist eine höhere Qualität der Inhaltserschließung vor allem im Sinne von Einheitlichkeit und Eindeutigkeit und, daraus resultierend, eine bessere Auffindbarkeit. Werden solche Entitäten miteinander verknüpft, z. B. Hermann Hesse mit einem seiner Werke, entsteht ein Knowledge Graph, wie ihn etwa Google bei der Inhaltserschließung des Web verwendet (Singhal 2012). Die Entwicklung des Google Knowledge Graph und das hier vorgestellte Protokoll sind historisch miteinander verbunden: OpenRefine wurde ursprünglich als Google Refine entwickelt, und die Funktionalität zum Abgleich mit externen Datenquellen (Reconciliation) wurde ursprünglich zur Einbindung von Freebase entwickelt, einer der Datenquellen des Google Knowledge Graph. Freebase wurde später in Wikidata integriert. Schon Google Refine wurde zum Abgleich mit Normdaten verwendet, etwa den Library of Congress Subject Headings (Hooland et al. 2013).

Araújo, P.C. de ; Gutierres Castanha, R.C. ; Hjoerland, B.: Citation indexing and indexes.
In: Knowledge organization. 48(2021) no.1, S.72-101.
(Reviews of Concepts in Knowledge Organization)

Abstract: A citation index is a bibliographic database that provides citation links between documents. The first modern citation index was suggested by the researcher Eugene Garfield in 1955 and created by him in 1964, and it represents an important innovation to knowledge organization and information retrieval. This article describes citation indexes in general, considering the modern citation indexes, including Web of Science, Scopus, Google Scholar, Microsoft Academic, Crossref, Dimensions and some special citation indexes and predecessors to the modern citation index like Shepard's Citations. We present comparative studies of the major ones and survey theoretical problems related to the role of citation indexes as subject access points (SAP), recognizing the implications to knowledge organization and information retrieval. Finally, studies on citation behavior are presented and the influence of citation indexes on knowledge organization, information retrieval and the scientific information ecosystem is recognized.

Roszkowski, M.: ¬The sociological and ontological dimensions of the knowledge organization domain on Google Scholar citations.
In: Knowledge organization. 47(2020) no.2, S.160-172.

Abstract: This study aims to identify the profiles of researchers in the knowledge organization domain on Google Scholar Citations (GSC) and investigate its sociological and ontological dimensions. The sociological dimension is related to GSC users who declared research interests that fall within the scope of the knowledge organization domain. The ontological dimension is based on the study of these concepts. Domain analysis was used as a methodological framework for this study. A search was conducted on GSC using keywords in order to create a list of scholars who declared the knowledge organization domain as one of their research interests in their Google Scholar Profiles (GSPs). Next, the search for GSPs of authors who had published their papers in the Knowledge Organization journal from 2000 to 2019 was conducted. The results showed that there were 379 publicly available GSPs. Analysis of the affiliated institutions showed that the majority of them were based respectively in the USA, Brazil, and then in India. The ontological dimension of the knowledge organization domain on GSC was examined by studying keywords attached to GSPs. The most frequently used keywords were identified and using network analysis five clusters that represented the main areas of interest were extracted.

Tay, A.: ¬The next generation discovery citation indexes : a review of the landscape in 2020.[11.11.2020].
In: http://musingsaboutlibrarianship.blogspot.com/2020/11/the-next-generation-discovery-citation.html.

Abstract: Conclusion There is a reason why Google Scholar and Web of Science/Scopus are kings of the hills in their various arenas. They have strong brand recogniton, a head start in development and a mass of eyeballs and users that leads to an almost virtious cycle of improvement. Competing against such well established competitors is not easy even when one has deep pockets (Microsoft) or a killer idea (scite). It will be interesting to see how the landscape will look like in 2030. Stay tuned for part II where I review each particular index.

Lewandowski, D. ; Sünkler, S.: What does Google recommend when you want to compare insurance offerings?.
In: Aslib journal of information management. 71(2019) no.3, S.310-324.

Abstract: Purpose The purpose of this paper is to describe a new method to improve the analysis of search engine results by considering the provider level as well as the domain level. This approach is tested by conducting a study using queries on the topic of insurance comparisons. Design/methodology/approach The authors conducted an empirical study that analyses the results of search queries aimed at comparing insurance companies. The authors used a self-developed software system that automatically queries commercial search engines and automatically extracts the content of the returned result pages for further data analysis. The data analysis was carried out using the KNIME Analytics Platform. Findings Google's top search results are served by only a few providers that frequently appear in these results. The authors show that some providers operate several domains on the same topic and that these domains appear for the same queries in the result lists. Research limitations/implications The authors demonstrate the feasibility of this approach and draw conclusions for further investigations from the empirical study. However, the study is a limited use case based on a limited number of search queries. Originality/value The proposed method allows large-scale analysis of the composition of the top results from commercial search engines. It allows using valid empirical data to determine what users actually see on the search engine result pages.

Luo, M.M. ; Nahl, D.: Let's Google : uncertainty and bilingual search.
In: Journal of the Association for Information Science and Technology. 70(2019) no.9, S.1014-1025.

Abstract: This study applies Kuhlthau's Information Search Process stage (ISP) model to understand bilingual users' Internet search experience. We conduct a quasi-field experiment with 30 bilingual searchers and the results suggested that the ISP model was applicable in studying searchers' information retrieval behavior in search tasks. The ISP model was applicable in studying searchers' information retrieval behavior in simple tasks. However, searchers' emotional responses differed from those of the ISP model for a complex task. By testing searchers using different search strategies, the results suggested that search engines with multilanguage search functions provide an advantage for bilingual searchers in the Internet's multilingual environment. The findings showed that when searchers used a search engine as a tool for problem solving, they might experience different feelings in each ISP stage than in searching for information for a term paper using a library. The results echo other research findings that indicate that information seeking is a multifaceted phenomenon.

Suranofsky, M. ; McColl, L.: a Google sheets add-on that uses the WorldCat search API : MatchMarc.
In: Code4Lib journal. Issue 46(2019), [http://journal.code4lib.org].

Abstract: Lehigh University Libraries has developed a new tool for querying WorldCat using the WorldCat Search API. The tool is a Google Sheet Add-on and is available now via the Google Sheets Add-ons menu under the name "MatchMarc." The add-on is easily customizable, with no knowledge of coding needed. The tool will return a single "best" OCLC record number, and its bibliographic information for a given ISBN or LCCN, allowing the user to set up and define "best." Because all of the information, the input, the criteria, and the results exist in the Google Sheets environment, efficient workflows can be developed from this flexible starting point. This article will discuss the development of the add-on, how it works, and future plans for development.

Farney, T.: using Google Tag Manager to share code : Designing shareable tags.
In: Code4Lib journal. Issue 46(2019), [http://journal.code4lib.org].

Abstract: Sharing code between libraries is not a new phenomenon and neither is Google Tag Manager (GTM). GTM launched in 2012 as a JavaScript and HTML manager with the intent of easing the implementation of different analytics trackers and marketing scripts on a website. However, it can be used to load other code using its tag system onto a website. It's a simple process to export and import tags facilitating the code sharing process without requiring a high degree of coding experience. The entire process involves creating the script tag in GTM, exporting the GTM content into a sharable export file for someone else to import into their library's GTM container, and finally publishing that imported file to push the code to the website it was designed for. This case study provides an example of designing and sharing a GTM container loaded with advanced Google Analytics configurations such as event tracking and custom dimensions for other libraries using the Summon discovery service. It also discusses processes for designing GTM tags for export, best practices on importing and testing GTM content created by other libraries and concludes with evaluating the pros and cons of encouraging GTM use.

Hodges, D.W. ; Schlottmann, K.: better archival migration outcomes with Python and the Google Sheets API : Reporting from the archives.
In: Code4Lib journal. Issue 46(2019), [http://journal.code4lib.org].

Abstract: Columbia University Libraries recently embarked on a multi-phase project to migrate nearly 4,000 records describing over 70,000 linear feet of archival material from disparate sources and formats into ArchivesSpace. This paper discusses tools and methods brought to bear in Phase 2 of this project, which required us to look closely at how to integrate a large number of legacy finding aids into the new system and merge descriptive data that had diverged in myriad ways. Using Python, XSLT, and a widely available if underappreciated resource-the Google Sheets API-archival and technical library staff devised ways to efficiently report data from different sources, and present it in an accessible, user-friendly way,. Responses were then fed back into automated data remediation processes to keep the migration project on track and minimize manual intervention. The scripts and processes developed proved very effective, and moreover, show promise well beyond the ArchivesSpace migration. This paper describes the Python/XSLT/Sheets API processes developed and how they opened a path to move beyond CSV-based reporting with flexible, ad-hoc data interfaces easily adaptable to meet a variety of purposes.

Lewandowski, D. ; Kerkmann, F. ; Rümmele, S. ; Sünkler, S.: ¬An empirical investigation on search engine ad disclosure.
In: Journal of the Association for Information Science and Technology. 69(2018) no.3, S.420-437.

Abstract: This representative study of German search engine users (N?=?1,000) focuses on the ability of users to distinguish between organic results and advertisements on Google results pages. We combine questions about Google's business with task-based studies in which users were asked to distinguish between ads and organic results in screenshots of results pages. We find that only a small percentage of users can reliably distinguish between ads and organic results, and that user knowledge of Google's business model is very limited. We conclude that ads are insufficiently labelled as such, and that many users may click on ads assuming that they are selecting organic results.

Abad-García, M.-F. ; González-Teruel, A. ; González-Llinares, J.: Effectiveness of OpenAIRE, BASE, Recolecta, and Google Scholar at finding spanish articles in repositories.
In: Journal of the Association for Information Science and Technology. 69(2018) no.4, S.619-622.
(Brief communication)

Abstract: This paper explores the usefulness of OpenAIRE, BASE, Recolecta, and Google Scholar (GS) for evaluating open access (OA) policies that demand a deposit in a repository. A case study was designed focusing on 762 financed articles with a project of FIS-2012 of the Instituto de Salud Carlos III, the Spanish national health service's main management body for health research. Its finance is therefore subject to the Spanish Government OA mandate. A search was carried out for full-text OA copies of the 762 articles using the four tools being evaluated and with identification of the repository housing these items. Of the 762 articles concerned, 510 OA copies were found of 353 unique articles (46.3%) in 68 repositories. OA copies were found of 81.9% of the articles in PubMed Central and copies of 49.5% of the articles in an institutional repository (IR). BASE and GS identified 93.5% of the articles and OpenAIRE 86.7%. Recolecta identified just 62.2% of the articles deposited in a Spanish IR. BASE achieved the greatest success, by locating copies deposited in IR, while GS found those deposited in disciplinary repositories. None of the tools identified copies of all the articles, so they need to be used in a complementary way when evaluating OA policies.

Gantman, E.R. ; Dabós, M.P.: Research output and impact of the fields of management, economics, and sociology in Spain and France : an analysis using Google Scholar and Scopus.
In: Journal of the Association for Information Science and Technology. 69(2018) no.8, S.1054-1066.

Abstract: Because of a greater coverage of documentary sources in many languages that is greater than that of traditional bibliographic databases, Google Scholar is an ideal tool for examining the social sciences in non-Anglophone countries. We have therefore used it to study the scholarly output and impact of three scientific disciplines, management, economics, and sociology, in Spain and France, comparing some of the results with those retrieved with Scopus. Our findings show that scientific articles are the predominant form of scholarly communication in Google Scholar for our selected fields and countries. In addition, our results indicate that in Google Scholar the vernacular languages of each country are more used than English in all cases, but economics in France. The opposite occurs in Scopus, except for the case of sociology articles in France We also show that books receive on average more citations than other published documents in Google Scholar. Finally, we demonstrate that publishing in English is associated with greater scholarly impact, except for the case of France in Google Scholar for articles in sociology and books in the three fields.

Abdelkareem, M.A.A.: In terms of publication index, what indicator is the best for researchers indexing, Google Scholar, Scopus, Clarivate or others?.
In: https://www.researchgate.net/post/In_terms_of_publication_index_what_indicator_is_the_best_for_researchers_indexing_Google_Scholar_Scopus_Clarivate_or_others.

Abstract: I believe that Google Scholar is the most popular academic indexing way for researchers and citations. However, some other indexing institutions may be more professional than Google Scholar but not as popular as Google Scholar. Other indexing websites like Scopus and Clarivate are providing more statistical figures for scholars, institutions or even journals. On account of publication citations, always Google Scholar shows higher citations for a paper than other indexing websites since Google Scholar consider most of the publication platforms so he can easily count the citations. While other databases just consider the citations come from those journals that are already indexed in their database

Bilal, D. ; Gwizdka, J.: Children's query types and reformulations in Google search.
In: Information processing and management. 54(2018) no.6, S.1022-1041.

Abstract: We investigated the searching behaviors of twenty-four children in grades 6, 7, and 8 (ages 11-13) in finding information on three types of search tasks in Google. Children conducted 72 search sessions and issued 150 queries. Children's phrase- and question-like queries combined were much more prevalent than keyword queries (70% vs. 30%, respectively). Fifty two percent of the queries were reformulations (33 sessions). We classified children's query reformulation types into five classes based on the taxonomy by Liu et al. (2010). We found that most query reformulations were by Substitution and Specialization, and that children hardly repeated queries. We categorized children's queries by task facets and examined the way they expressed these facets in their query formulations and reformulations. Oldest children tended to target the general topic of search tasks in their queries most frequently, whereas younger children expressed one of the two facets more often. We assessed children's achieved task outcomes using the search task outcomes measure we developed. Children were mostly more successful on the fact-finding and fully self-generated task and partially successful on the research-oriented task. Query type, reformulation type, achieved task outcomes, and expressing task facets varied by task type and grade level. There was no significant effect of query length in words or of the number of queries issued on search task outcomes. The study findings have implications for human intervention, digital literacy, search task literacy, as well as for system intervention to support children's query formulation and reformulation during interaction with Google.
