There are a variety of methods used by the ICTS Tracking & Evaluation team to assess the impact of ICTS publications on scientific and scholarly work. One way to assess the impact of an ICTS member’s research is to chart the number of times a publication is cited by subsequent publications in the peer-reviewed literature [Garfield, PMID 14385826].
There were approximately 4,593 unique peer-reviewed publications authored in 2016 by ICTS members indexed in Elsevier Scopus (publication types: 3,807 articles, 187 conference papers, 565 reviews and 34 short surveys).
There were 23,063 citations for the 2016 publications noted in Elsevier SciVal as of September 2017 with an average of 5 citations per publication. 3,403 of the 2016 publications have been cited at least once since September 2017. The Field-Weighted Citation Impact (FWCI) of the 2016 pblications is 2.49. The FWCI is defined as the ratio of the total citations actually received by the denominator's output, and the toltal citations that would be expected based on the average of the subject fieled. A FWCI of:
- Exactly 1 means that the output performs just as expected for the global average.
- More than 1 means that the output is more cited than expected according to the global average; for example, 1.48 means 48% more cited than expected.
- Less than 1 means that the output is cited less than expected according to the global average.

The publication with the highest citation count garnered 893 citations, with 17 publications having more than 100 citations each. 1,454 (31.7%) of the publications were in the top 10% of the most cited publications worldwide; 6.5% were in the top 1%, per SciVal.
Percentile and Average Citation Rates
The top 50 cited publications in Elsevier Scopus were also compared to Clarivate Analytics (formerly Thompson Reuters) Web of Science and Essential Science Indicators (ESI) for further citation analysis.
According to ESI, as of September 2017, the average citation rate for a paper published in 2016 for all fields/disciplines is 1.57. A publication published in 2016 that garners 15 citations as of September 2017 falls in the top 1% of cited publications for all fields/disciplines. 49 of the top 50 cited publications authored by ICTS members in 2016 were in the top 1% of cited publications for all fields/disciplines with at least 35 citations. The highest citation count for a publication was 859. 11 of the top 50 publications were in the top 01.1% of cited publications for all fields/disciplines with 120 or more citations each.
"Hot Papers” as defined by Clarivate Analytics Essential Science Indicators are publications that are recognized by frequent citations within two years of publication. Hot papers are an indicator of exceptional research importance and are often key papers in their fields. Since the publications are evaluated in relationship to others in their specific field and is a measure of significance at a particular moment in time, the ICTS Tracking & Evaluation team repeats this analysis annually to track citation patterns over time.
Research Front Papers (formerly known as Core Papers)
Research Front papers represent emerging areas in the research landscape. They are determined by Clarivate Analytics Essential Science Indicators, which takes the set of highly cited papers and performs a cluster analysis of co-citations (being cited in conjunction with other highly cited papers). Since this is another indicator of scientific research impact, the ICTS Tracking & Evaluation team repeats this analysis annually to track citation patterns over time. A publication being both a "Hot Paper” and a "Research Front Paper” is a significant indicator of impact.
Highly Cited Papers
“Highly Cited Papers” as defined by Clarivate Analytics Essential Science Indicators are papers that continue to demonstrate high citation rates for up to ten years after publication. These are papers that report discoveries and gradually increase in citation frequency as the methods diffuse throughout the community and prove their utility.
