Our Distinguished Professor Ioannis Liritzis in the list of top 2% World Scientists.



On 2023, for third consecutive year Distinguished Professor Ioannis Liritzis (Natural Sciences in Cultural Heritage, Archaeology & Palaeoenvironment) of Henan University, is named in the world’s top 2% of Scientists List.

The publication authors created a publicly available database of top-cited scientists that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator (c-score).

Separate data are shown for career-long and, separately, for single recent (last) year impact.

In both data lists Prof. Ioannis Liritzis is included with improved scores.

The three fields he has been evaluated are: Historical Studies, Archaeology, Astronomy, although he has produced research publications in other fields too.

For Carrier total achievement in the subfield Archaeology out of 16232 scientists of subfield Archaeology he has rank of score category author fraction 0.41 or 0.84% (1.35% in 2020) (in astronomy 0.12 and History 0.45), and for Recent year the rank of composite score excluding self-citations  (ns) within category sm-subfield-1: Archaeology: 0.41 or 0.49%, History:0.45 and Astronomy:0.12.

Metrics with and without self-citations and ratio of citations to citing papers are given. Scientists are classified into 22 scientific fields and 174 sub-fields according to the standard Science-Metrix classification. Field- and subfield-specific percentiles are also provided for all scientists with at least 5 papers. Career-long data are updated to end-of-2022 and single recent year data pertain to citations received during calendar year 2022. The selection is based on the top 100,000 scientists by c-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field. This version (6) is based on the October 1, 2023 snapshot from Scopus, updated to end of citation year 2022. This work uses Scopus data provided by Elsevier through ICSR Lab ( Calculations were performed using all Scopus author profiles as of October 1, 2023.
