چکیده:
Bibliometric, and scientometric approaches are used to provide appropriate tools for evaluating scientific products at local, national, and international levels. Iran, the same as other countries, has many universities and research centers in the field of engineering that Iran's most of the scientific products account for the field of engineering. This study is a descriptive approach using scientometric methods. is The present paper mainly focuses on visualizing the structure of the Iranian scientific publications in the field of engineering indexed in Thomson Reuters (ISI) accessible via WoS during 1939-2011. To draw the historiographical map of Iranian scientific outputs in the field of engineering, this study used HistCiteTM software. Two indexes, Local Citation Score and Global Citation Score, were used for the purpose of ranking and visualizing data. The results showed that the published papers of Iranian researchers in the field of engineering showed fluctuation. The proportion of Iran in the engineering outputs constituted 0.65% of total publications and ranked 24 of the world. Five large clusters have been formed on the LCS index. The subject areas of the clusters were in “Thermodynamics and Chemical engineering”, “N-O Explosives, “liquid membranes”, “Liquid–liquid equilibrium”, and “decolorization”. However, three clusters have been formed on the GCS index. The subject areas of the clusters were in “liquid membranes”, “applied chemistry”, and “Liquid–liquid equilibrium”. Zafarani-Moattar and Sadeghi, and Ganji, played an important role in this map.

These tools have a number of advantages, including identifying core and significant journals, authors, institutions, universities, and papers; navigating thoughts and developing literatures and resources; anticipating scientific products trend; visualizing different subject fields and determining the most important subjects; identifying collaboration and co-authorship patterns; comparing courtiers based on scholarly publications etc.
In particular, this paper focuses on: • Iranian research output, its growth trend, and global publication's share and impacts; • the types and languages of the documents; • the most important universities, institution and journals; • countries whose academics have the most frequent collaboration with Lanian researchers; • the most productive and highly cited Iranian authors in the field of engineering; • the most effective Iranian engineering articles based on citation; • the historiographical map of Iranian scientific publications of engineering; • the most important scientific subject clusters formed in the field of engineering.
Findings Iranian research output, its growth trend, and global publication ’s share and impact The results of the study showed that 28010 kanian scientific outputs were published by engineering researchers indexed by Web of Science (WoS).
First of all, we will consider documents that have been the most citation rates based on LCS and GCS indexes, and then we will analyze formed subject clusters in maps which were extracted from Iranian engineering scientific products based on above-mentioned indexes.
Clusier5 in LCS level Analyzing the subject clusters of Iranian engineering scientific products based on MCS This study extracted 600 top documents that received the most global citations.
