Examining the trend of research on chemometric analysis: a bibliometric review / Sarifah Fauziah Syed Draman

Bibliometrics analysis is a technique that refers to the collection, the handling, and the quantitatively assess of bibliographic data, resulting from scientific publications. This bibliometric review aimed to examine the trend of research on chemometric analysis over the past 37 years (1983-2020). Chemometrics is the chemical discipline that uses mathematical, statistical and other methods to design or select optimal measurement procedures and experiments. By analysing chemical data, chemometric analysis can provide the full relevant chemical information needed. Various areas and principles such as multivariate statistics and pattern recognition, time series analyses, information technology, computation, numerical analysis, operations research, decision theory and operations research contribute to chemometrics. This bibliometric review was applied to examine the chemometric analysis research trend between 1983-2020 using the Scopus-indexed documents. There are many research types on the chemometric analysis carried out by the researcher during the study period. This study's finalised 1299 documents were conducted overall for further analysis based on the' title' search results. Standard bibliometric indicators were used in this review analysis. Two software is used (Harzing Perish and VOSviewer) in completing the bibliometric review. This study found 12 types of documents that have been published related to chemometric analysis. 89.92 % of the total publications were from articles. The highest source type is journals (94.53%). The first research on chemometric analysis was published in the year of 1983. Then, the growth of the related publications has risen gradually. However, there is some decrease in publications between the years. English is the top language used in the publications. An analysis by country, China is ranked first in productivity with 225 (13.64%) published documents. Citation analysis identified key authors and documents that have shaped the progress of this review. Author co-citation analysis used to determine the intellectual structure of the chemometric analysis knowledge base. In conclusion, this review can better understand development trends that have emerged in this chemometric analysis over the past 37 years. Furthermore, the review result can also offer a reference for future research.
