SCOPUS Vs. Web of Science SCOPUS Vs. Web of Science Introduction Once you have retrieved articles through a global search, you will need to consult one of the two major search engines devoted to academic and scientific articles. Both SCOPUS and Web of Science are very large, subscription-based databases that allow users to search for indexed contents. Each database allows extensive searches into various domains of science and academic literature. The databases include impact, productivity, and citation algorithms that measure an article’s or author’s impact on their respective fields. Both databases have differences in metrics calculations, which should be taken into consideration (Table 1). Both systems rely on quartiles (Q) which are bands of serial titles that have been grouped together because they occupy a similar position within their subject categories. The four quartiles are denominated Q1, Q2, Q3, and Q4. Percentiles indicate the relative standing of a serial title in its subject field. Each subject field is divided into 100 equal-sized percentiles based on the number of serial titles, and a serial title is assigned to a percentile based on its CiteScore. 2 of 30 SCOPUS Vs. Web of Science Dating back to 1900, Web of Science (abbreviated as WoS), formerly the Web of Knowledge, is an online citation index service produced by the Institute for Scientific Information (ISI) and now maintained by Clarivate Analytics. In 2014, Clarivate declared that Web of Science’s databases host over 50,000 scholarly books, 12,000 Journals, and 160,000 conference proceedings. Web of Science specializes in the sciences, social sciences, art, and humanities. Annually, Clarivate publishes The Journal Citation Reports, which provide analytic information on the academic performance of its Journals through Journal Impact Factors (JIF), Eigenfactor and Citation indexes. JIF is an important measure for the performance of a Journal. It is calculated via the equation below: "#$%& '($%$(#)* () +%', -+%. .+'+(/+0 1#. $,+ ($+2* 345&(*,+0 () $,+ 3%*$ $6# -+%.* JIF = "#$%& )425+. #1 '($%5&+ ($+2* 3.#04'+0 () $,+ 3%*$ $6# -+%.* For example, if a Journal reports that JIF = 5 in 2019, this means that, on average, each article produced by the Journal in 2017 and 2018 received five citations. 3 of 30 SCOPUS Vs. Web of Science SCOPUS, on the other hand, is a database of peer-reviewed literature launched in 2004 by Elsevier. SCOPUS partners with over 5000 publishers, hosts over 22,000 serial titles, 150,000 books and has 1.4 billion cited references dating back to 1966. A simple comparison shows that the database of SCOPUS is much more extensive than that of WoS. All SCOPUS Journals are reviewed annually to measure quality standards. There are three quality indexes: The Cite-Score, SCImago Journal Rank (SJR), and Source Normalized Impact per Paper (SNIP). SCOPUS also provides citations and indexes for conference proceedings. CiteScore plays the same role as that of JIF but with one difference. The former evaluates a Journal’s performance over the past three years, while the latter measures the impact of a Journal over the past two years. For that reason, these two evaluation parameters are not directly comparable. Nonetheless, they show the importance and impact of the Journal in its field. "#$%& '($%$(#)* () +%', -+%. .+'+(/+0 1#. $,+ ($+2* 345&(*,+0 () $,+ 3%*$ $,.++ -+%.* CiteScore = "#$%& )425+. #1 0#'42+)$* 3.#04'+0 () $,+ 3%*$ $,.++ -+%.* 4 of 30 SCOPUS Vs. Web of Science Searching Through Web of Science To get the most out of searching through the Web of Science database, consider creating an account so that you can save searches and citations for consulting later. The Tecnologico de Monterrey provides faculty and students with access to the Web of Science through the institutional login. The next step in accessing the Web of Science is through the library’s website. As you take this step, consider using Firefox or Chrome as your web browser, because the library site is geared towards these search engines. 5 of 30 SCOPUS Vs. Web of Science Go to Biblioteca Tec by typing (https://biblioteca.tec.mx/inicio) into your browser bar. This will lead you to the BiblioXplora main page (Figure 1). Figure 1: Biblioteca search bar 6 of 30 SCOPUS Vs. Web of Science Click on the “Buscar” drop-down menu (Figure 2) and click the “Bases de Datos” tab (Figure 3). Figure 2: Buscar tab Figure 3: Web of Science through Biblioteca Tec 7 of 30 SCOPUS Vs. Web of Science In the search box, type, “Web of Science.” It is important to remember that this page is not typically accessible if you are outside an institution that has a subscription to the Web of Science. Click “Ir” (“Go”) next to the search box (Figure 4). Figure 4: Accessing Web of Science through Biblioteca Tec 8 of 30 SCOPUS Vs.

Click “Enviar.” Figure 5: Biblioteca login 9 of 30 SCOPUS Vs. Web of Science By doing so, you are directly guided to the Web of Science website (Figure 6). Figure 6: Web of Science search 10 of 30 SCOPUS Vs. Web of Science Click the “Journal Citation Reports” tab at the top of the webpage (Figure 7). Type the journal name into the Web of Science search bar. Click the “search” button. A new tab will open with a list of matching journals. Figure 7: Journal citation reports, Web of Science 11 of 30 SCOPUS Vs. Web of Science However, if you do not find the journal in your first attempt, do not get disappointed. Sometimes the titles of the journals are slightly different in the databases. For example, Biosensors and Bioelectronics is one of the most influential journals in the field of biosensing. If you search "Biosensors and Bioelectronics," no results appear on the Web of Science platform. However, if you search “Biosensors & Bioelectronics,” the journal can be found. Worked Example – Web of Science Consider the example of searching the journal titled, Computers and Human Behavior. Follow the previous steps and log in through the Tec login at Biblioteca and reach the Web of Science search page. 12 of 30 SCOPUS Vs. Web of Science In the search term box, type in the name of the journal (Figure 8). Figure 8: “Computers in Human Behavior” entered into the Web of Science search bar 13 of 30 SCOPUS Vs. Web of Science The results should take you to the Web of Science metrics page for the journal as can be seen in Figure 9. This page provides a range of information including the ISSN, the publishing country the company, and the year journal was established. Figure 9: Results for Computers in Human Behavior from Web of Science metrics page. 14 of 30 SCOPUS Vs. Web of Science As you scroll down, the first graphic shows the JIF as an absolute value and the percentile score over the last 5 years. Computers in Human Behavior had a JIF of 3.536 in 2017 (Figure 10). Figure 10: Journal Impact Factor for Computers in Human Behavior, Web of Science 15 of 30 SCOPUS Vs. Web of Science Scrolling down will show how the JIF is calculated. The JIF is made by aggregating the number of citations made in the previous year (2017 in the above example) to journals in the two years prior (2015 and 2016) and dividing that by the number of documents published in the journal for those two prior years. (Figure 11). Figure 11: Method for JIF calculation, Web of Science 16 of 30 SCOPUS Vs. Web of Science The JIF has a great significance in the Web of Science indexing. The absolute values of the JIFs are reported in percentiles to show how a particular journal performs in comparison to other journals in the same academic field. Computers in Human Behavior is ranked in the 92nd percentile for Experimental Psychology and in the 89th percentile for Multidisciplinary Psychology. Interpreting Data JIF is the Web of Science method for organizing journal quartiles or ranks. Quartiles divide the entire spectrum of ranks into four parts. Quartile 1 (Q1) represents journals ranked from 100 to 75, for example. For reference, Q1 = 100–76th, Q2 = 75–51st, Q3 = 50–26th, and Q4 = 25–1st. 17 of 30 SCOPUS Vs. Web of Science Algorithm indexes show the most cited articles from the journals. You can see the most cited articles and distributions of citations by selecting the “All Years” tab (Figure 12). This provides a detailed table of various indicators, including total cites, journal impact factor, the 5-year impact factor, and the Eigenfactor score. Figure 12: Detailed indicators, Computers in Human Behavior 18 of 30 SCOPUS Vs. Web of Science When researching emerging fields, it is crucial to find articles from journals that are growing in influence. The most important data here are the Total Cites, Journal Impact Factor, the 5-year impact factor, and the Eigenfactor Score. Total Cites shows the number of citations given to journals published in that year. This data shows that Computers in Human Behavior has had a positive trend and has been consistently improving, as also shown in Figure 10. Check to see if your chosen article is from either a Q1 or a Q2 journal. If the journal is ranked Q1 or Q2, keep the article for more consideration. If the journal is Q3 or Q4, consider seriously whether the citation has enough relevance and timeliness to include the article in your final literature review. Use this quartile methodology for all your article citations gathered from the Global Search section. 19 of 30 SCOPUS Vs.
