Web of Science: Using a Citation Database: Pearl Growing/Citation Mining and Related Records

Using Citing and Cited References to Find Further Relevant Citations

"Pearl Growing" (also known as "Citation Mining" or "Snowballing") is a search strategy that uses a good citation you've already found (the "pearl") to find further relevant citations. When you find a pearl, Web of Science uses citation data to help you find more.

Click on an article title to see its full record, and note the links to Times Cited, Cited References, and to view related records.


Times Cited: shows the number of articles which have cited this article (also called "forward citations").  Click on the linked number to see the list of citing articles. These citing references will likely be about similar or related topics.

The Times Cited Search Results page provides the same options as the general Search Results page. You can Search Within Results, Refine Search and Sort by Times Cited.

tipTip: Sort the citing articles by Times Cited to find new pearls.

Cited References: shows the number of articles which this article has cited (also called backward citations). Click on the linked number to see a list of cited articles. These cited references will likely be about similar or related topics.

tipTip: Viewing the cited references of a systematic review is a good way to find several relevant studies on your topic.  Additionally, viewing cited references may contain citations for articles which have laid the groundwork in your area of study.

Related Records

Using the Related Records option is another avenue for finding relevant papers on a topic.The assumption behind Related Records searching is that articles that cite the same works have a subject relationship, regardless of whether their titles, abstracts, or keywords contain the same terms. The more cited references two articles share, the closer the subject relationship.  From a broader perspective, shared references demonstrate the shared interests of researchers building from and adding to a body of work. Shared citations reveal the research networks linking them.

Search for Related Records
On the Full Record page of a citation, click the View Related Records option underneath the citing and cited references. Alternatively, on the Cited Reference list for a citation, you can select the checkbox next to one or more citations and then click the Find Related Records option to see a list of records that cite at least one document in the reference list of a parent record. 

If you access Related Records from the Cited References page, you can refine your search by not selecting unneeded references. Those records are not factored into the Related Records algorithm (whereas selecting View Related Records directly on the citation page, Web of Science will look for related records for all references on the Cited References list).

Results
Related Records are ranked according to the number of references they share with the parent record.

You can search within results or Refine Results, e.g., by date.

Shared References
To view shared references, click the number in the Shared Refs column.

Example
The example in the screenshot, left, is the Related Records result page from the article Circadian arrhythmia dysregulates emotional behaviors in aged Siberian hamsters. The top citaiton on the list shares 19 references in common with the cited references for this article.  The next citation on the list shares 13 common references with the article.
