The origin of many of the problems encountered in research in the field of knowledge and information science (such as non-applicability, repetition, and lack of innovation) relates to the uncertainty of research needs and priorities in this field. In this regard, the purpose of this study is to identify and categorize important research topics in knowledge and information science, and to measure their significance in order to determine research priorities in this field.
The present research is a theoretical-practical type and a research method-analytical and survey method. The research population consists of faculty and doctoral students in the field of knowledge and information science in the universities of Tehran, Kharazmi, Al-Zahra, Mashhad Ferdowsi, Shiraz, Esfahan and Shahid Chamran in the academic years 2015-2016. Due to the limited research community (165 persons), a questionnaire was distributed among all the people in the distribution community (electronically and in person) and finally 112 questionnaires were collected (return rate 63%). For data analysis, inferential statistics (Friedman rank test) has been used.
In order to identify research priorities in knowledge and information science, the contents of this field and the opinions of the faculty of this field have been reviewed. The results of these studies identified 120 topics in knowledge and information science that were divided into 22 general axes.
The results indicate that the research community should consider new and applied topics, future topics and issues related to information  technology to the traditional topics and theoretical topics for further research in this field. This is due to developments in the field of knowledge and information science in recent years (including changing the title of the course and, to some extent, changing the curriculum, and then changing the content of the discipline, the changes brought about by technology entry into the field and Moving further into this area becomes more interdisciplinary).
