The present study determines the co-authorship factor in the Iranian scientific output between 2000 and 2006 as reflected in the science, social science art and humanities citation indexes made available through the Web of Science database. Webometric indicators were used. The data were extracted in plain text from WOS, analyzed using HistCite software and counted in MS Office Excel program. Of the Total of 25320 documents indexed, 24480 documents were in Science Citation Index, 783 in Social Citation Index and 57 in Art and Humanities index. The findings indicated that co-authorship factor in the period studied had been on the rise. The highest participation rate belonged to the documents with two or three authors. General coauthorship factor was 0.59. The year 2006 had the highest coauthorship factor (0.62) while the year 2000 had the least (0.55). Bradford and Lotka laws were applied to the data sets. The Lotka's Law only held true for the science citation index. The Bradford's Law, however, held true for all indexes. In all citation indexes, the United States with 1865 documents (7.38) had the highest degree of coauthorship in Iranian scientific output.

This research aims to investigate the citations received by DOAJ's journals from ISI Web of Science's articles in five fields (Arts & Humanities, Social Sciences, Pure Sciences, Technology & Engineering, and Health & Medical Sciences) during 2003-2008. It was used bibliometrics and citation analysis. In this research 2953 English-language journals in DOAJ were chosen, and no sampling was used. The research data have been gathered by means of Cited Reference Search in ISI Web of Science and after counting the number of citations in each field the journals were ranked (to the fifth rank) in terms of the number of the received citations. After studying the journals from DOAJ, it was clarified that 321 journals (10.87%) received citations, and these journals totally received 19050 citations. The average number of citations per journal was 6.45. Pure Sciences received most citations (10116 citations equal to 53.1%) and in this field Biology was in the first rank in terms of the number of citations (6009 citations equal to 50.4%) and Arts & Humanities received least citations (701 citations equal to 3.68%) and in this field Geography was in the last rank in terms of the number of citations (25 citations, equal to 3.57%). On the other hand, the Findings of Chi-square test are also indicative that there is a significant difference among the citations in terms of the mentioned-above five fields.

To visualize the structure of Iranian scientific output in Science Citation Index (SCI), accessible via Web of Science (WOS), during 2000-2006, we used scientometric techniques and HistCite software. The number of Iranian documents indexed in SCI during the study period was 24480. Generally HistCite analyzes citation data on two different levels: based on citations in WOS (Global Citation Scale), and citations in collection of retrieved documents (Local Citation Scale). The results of this study showed that, in the study period a total of 8 clusters have been formed on the two levels (GCS and LCS): Clusters 1 and 2 (with 3 sub-clusters) in GCS and clusters 3, 4, 5, 6, 7, and 8 in LCS. The subject area of whole clusters was chemistry, but different areas of this discipline. The prominent subject area in our study was organic chemistry. The most effective document in this study was an article by Zolfigol with 123 global citations and 71 local citations. The subject category of cluster 1 was analytical chemistry and membrane electrodes. Cluster 2 consists of 3 sub-clusters (sub-cluster 1 hydrocarbons, sub-cluster 2 in the field of oxidation and nitrogen, and sub-cluster 3 catalysts). Cluster 4 was crystal structure, cluster 5 electrochemical analysis, cluster 6 macro cycles, cluster 7 aliphatic and aromatic complexes and the 8th cluster was polymers. © 2010 Springer-Verlag.

In this research, the citations received by DOAJ's journals from the ISI Web of Science's articles in 2003 to 2008 were studied and compared. The citations received by the journals in five fields (Arts & Humanities, Social Sciences, Pure Sciences, Technology & Engineering, and Health & Medical Sciences) as well as the difference among the citations received by DOAJ's journals in the abovementioned five fields were examined. The research method is citation analysis and the research data have been collected by means of Cited Reference Search in the ISI Web of Science. The English-language journals in DOAJ were chosen, and no sampling was used. Findings showed that out of 2953 journals, 321 journals (10.87%) received citations, and the total citations received by these journals were 19050 with the mean of 6.45 per journal; the journals in Pure Sciences received most citations (10116 citations, equal to 53.1%), and the ones in Arts & Humanities received the least citations (701 citations, equal to 3.68%). On the other hand, the findings of Chi-Square test (χ2) indicate that there is a significant difference among the citations in the above-mentioned five fields.
