Введение. Для лучшего теоретического осознания понятия «impact’а» («воздействия»), введенного в оборот Ю. Гарфилдом в 1955 году, выполнен анализ употребляемых определений и трактовок этого понятия.

Материалы и методы

Материалы и методы. Аналитическая интерпретация научной литературы, имеющей отношение к данной проблеме (с 1955 года). Автор рассматривает понятие «воздействие» в его исходном значении «научного воздействия».

Результаты

Результаты. Общепризнанное определение понятия «impact» («воздействие») в настоящее время не сформировано. Существующие и используемые значения термина либо рассматриваются как синоним слова «влияние», либо не выходят за пределы понятия «сильное впечатление», либо совпадают со значением термина «пертинентность», либо относятся к чисто техническим индикаторам.

Обсуждение и заключение

Обсуждение и заключение. Сделан вывод, что нельзя считать «impact» ключевым понятием наукометрии, поскольку само понятие термина строго не определено.

Introduction

Introduction. For a better theoretical understanding of the notion of “impact” (introduced by E. Garfield in 1955) definitions and perceptions of the mentioned notion used in scientometric literature have been analyzed.

Materials and methods

Materials and methods. Analytical interpretation of the scientific literature related to this problem (since 1955). The author considers the concept “impact” in its initial meaning of ‘scientific impact’.

Results

Results. The existing and used meanings of the term “impact” either are treated as a synonym of “influence” or do not go beyond the concept of “strong impression”, or coincide with the meaning of the term “pertinence”, or refer to purely technical indicators.

Discussion and Conclusions. The conclusion has been made that that it is unreasonable to consider “impact” as a key notion of scientometrics because the notion is not sufficiently defined.
