'Iran world’s 21st knowledge producer' Iran has, for the first time, moved up to the 21st place in the world ranking in knowledge production, says the director of the Islamic World Science Citation Center. “Based on the latest report on Iran’s published scientific works at the Institute for Scientific Information (ISI), Iranian researchers secured the 21st place in the world ranking at the end of May in terms of the total number of scientific documents published by the ISI,” said ISC Director Jafar Mehrad. The highest scientific ranking for Iran up to now has been the 24th spot, he said, hailing efforts by Iranian researchers and scientists. Mehrad predicted that Iran would maintain the 21st spot in the future, thanks to the upward trend of knowledge production in the country. The ISC is a citation index established by the Iranian Ministry of Science, Research and Technology after it was approved by the Organization of the Islamic Conference. It only indexes journals from the Islamic world. Source: presstv.ir
