Aproaches towards cluster analysis

Abstract

Th e purpose of this study is to review cluster research and the methodology used to achieve the target. Specifi cally, this research explores the methods that are used in research papers aiming at cluster study. Bibliometrical analysis is used depending on an original database, created by the authors, selected after close review. 33 research papers were taken into consideration, published from 1999 to 2014 in international scientifi c journals. Th e fi ndings indicate that case study is used in many articles refering to cluster research. Other methods, such as analysis, interview, survey, research, equation and others are used to support case study. By analyzing the specifi c methods used in cluster research it is aimed at giving clarity to further research on the concept of cluster. It is well known that rather few research papers were analysed from the methodological point of view. However, this research requires a further analysis with a wider scope of scientifi c literature and works related to clusters.
