V Why a citation to a non-indexed document may appear in Web of Science 8 Section I: General Notes

a) In the Citation Metrics Workshop (Web of Science), Basic Level, we used the Author Search. We were limiting the results to documents which are indexed in the Web of Science. If Web of Science indexes 12,000 journals/conference proceedings, etc. The search is done only on these 12,000 sources.

b) In these advanced techniques, we use the Cited Reference Search instead of the Author Search to get results from sources that Web of Science does not index, as well as sources that are incorrectly cited (see Section II for examples of such sources).

c) When we use the Cited Reference Search, items will include those that appear in the reference lists of sources that Web of Science does index. See Section V for an example.

d) The author we are working on is Professor Somsak Swaddiwudhipong, Professor (Adjunct)

Department of Civil and Environmental Engineering. We search under: a. His name b. the co-author’s name when the co-author is the first author

i. Reason for (b): • If Somsak is the first author, his work will be retrieved regardless of whether the work is

from a source indexed by Web of Science or not.

• If Somsak is not the first author and Web of Science does not index the work, it will not be retrieved if we search using Somsak’s name. It will be retrieved only if we search under his co-author who is the first author.

Section II Documents not found using the Author Search but are found when using Cited Reference Search

a. These include:

• Documents not indexed [not properly recorded] by Web of Science: o Non-journals like books, theses, patents o Journals that are not selected by Web of Science editors

• “Odd” items [Cited Reference Variants]: o Documents with incorrect information(e.g. wrong page number) o Documents with missing information o Documents with variations in spelling

b. The following are examples of cited reference variants for one of Prof Somsak’s work:

c. Let’s look at another example below:

Page 3

a. Document no. is indexed in the WoS, because clicking on the hypertext title will take you to view the full record in WoS.

b. Document no. is a cited reference variant – it has a different volume numbering, the issue number is missing, the DOI is missing and there is a misspelled word in the title. It is obvious that this is an incorrect reference to the same article.

Note: In this handout, we are interested in all documents similar to Document no 1. We want to find out the total number of citations belonging to these documents.

This is similar to Secondary Document Search in Scopus.

Section III. Using the Cited Reference Search: Search Author’s Name 1. Enter Swaddiwudhipong, S in the Cited Author field. Enter the range of years according to his publication

history, i.e. 1977-2018 in the Cited Year(s) field. Click Search.

2. As shown in the screen shot below, the format of the records retrieved in this Cited reference search is different from those retrieved via the basic techniques.

a. Select the menu to confirm that Prof Somsak authored the records. Click on the menus to expand and view full titles of cited works (sources) and document titles.

b. For records with hypertext titles, click on the hypertext links to confirm if Web of Science indexes these records. We will include the citing article counts for these records if Web of Science does not index them.

c. Select the check box of the second record. Scroll down the results list and continue to select relevant records. We are looking for the author’s publications not indexed (in black font) in the Web of Science.

3. Copy the rows that you have selected for Prof Somsak’s works mentioned in the steps. Paste them onto an Excel worksheet. Sum up the total citing articles for the selected cited reference search results.

To view the list of articles citing your publication: a. Select articles by clicking on the check boxes b. Click Finish Search to view a list of the articles that have cited the author.

Section IV

Use “Cited Reference Search” to search for citation counts for an author who is not the first author.

1. Enter the first author’s name, perry, m* for Cited Author and singapore* for the Cited Work. The asterisk (*) serves as a wildcard used to retrieve all words with a given stem. Note that:

a. M* retrieves any variant names occurring after the alphabet M e.g. Martin, Michael... b. Singapore* retrieves words/phrases occurring after the root word Singapore

2. Examine the results list and select the records that match the author’s work. As explained earlier, exclude records that have hyperlinked titles since Web of Science indexes these records and the citing article counts have already been included in the Basic Search.

3. Copy the relevant records and paste these onto a blank Excel worksheet. Sum up the Citing Articles column to obtain the additional number of citations. Repeat the above steps for each of his/her co-authors.

E.g. Singapore: A Developmental City-State by Martin Perry, Lily Kong and Brenda Yeoh. New York : Wiley, 1997.

Section V Why citation to a non-indexed document may appear in Web of Science

Web of Science indexes the journal BREAST CANCER RESEARCH, but not ASIA PACIFIC POPULATION JOURNAL. One of the documents in volume 12, issue 1 (year 2010) of BREAST CANCER RESEARCH is:

Title: Risk factors for breast cancer in postmenopausal Caucasian and Chinese-Canadian women Author(s): Tam, Carolyn Y.; Martin, Lisa J.; Hislop, Gregory; et al. It has 28 references, one of which is an article from ASIA PACIFIC POPULATION JOURNAL, volume17, pages 5-10, published in 2002 written by Brenda Yeoh and A. Chan with title: Gender, family and fertility in Asia: An introduction

References:

Doing a cited reference search under Yeoh, B* would therefore retrieve the abovementioned article (see below).

This example also serves to show that although Brenda Yeoh is not a professor of Science or Medicine; her work gets cited in an article that concerns oncology, a medical field. This is why in step 1 of section III we select all databases including the Science ones. In Summary:

What is covered in Web of Science What can be retrieved Journals selected by its editors, e.g. Breast Cancer Research

A. Documents published in each issue of these journals (subject to years of coverage)

B. References found at the end of each of the above
