The main goal of this paper was to visualize and draw the intellectual and cognitive structures of information retrieval (IR) in the medical sciences using science mapping. </span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Methods:</b> In this cross-sectional scientometric study, we recruited all documents indexed in the Web of Science database with the topic of storing and retrieval of information in medical sciences. To analyze the results, 3 software, SciMAT-v1.1.04, VOSviewer-v1.6.14, CitNetExplorer_v1.0.0, were used. </span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Results:</b> Our results showed that most scientific productions in this field fall into 2 categories: (1) effective methods of organizing information and (2) application and operation of the IR system in the process of intelligent questioning and answering, and analyzing information behaviors of physicians and health professionals. The results showed that the similarity index increased over time from 0.43 to 0.71. Analysis of the findings showed that similarity measures, expert systems, concepts, experience, answers, and multimodel IR clusters were considered as mature and completely centralized clusters in the first quarter of the strategic chart. </span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Conclusion:</b> Because of the dramatic approximation of the vocabulary used by researchers and a relative slowdown in the growth rate of the subject&#39;s domain in the last decade, it seems necessary to pay attention to the expansion of the fields of IR and the application of its concepts in medical information sciences. Also, it can be recommended that designers of IR systems and techniques in medical information sciences pay more attention to human factors attentively to develop new technologies and tools.</span></span></span></span></span></span></span></span> Medical And Health Science, Information Retrieval, Citation Network, Scientometric, Research Trends 451 462 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-6861-1&slc_lang=en&sid=1 Masoud Mohammadi Mohammadi.msd84@gmail.com 200319475328460070869 200319475328460070869 No Department of Medical Library and Information Sciences, School of Allied Medical Sciences, Tehran University of Medical Sciences, Tehran, & Research Center of Gastroenterology and Hepatology, Golestan University of Medical Sciences, Gorgan, Iran Gholamreza Roshandel roshandel.g@gmail.com 200319475328460070870 200319475328460070870 No Research Center of Gastroenterology and Hepatology, Golestan University of Medical Sciences, Gorgan, Iran Seyed Javad Ghazimirsaeid jghazi37@gmail.com 200319475328460070871 200319475328460070871 No Department of Medical Library and Information Sciences, School of Allied Medical Sciences, Tehran University of Medical Sciences, Tehran, Iran Marzieh Zarinbal zarinbal@irandoc.ac.ir 200319475328460070872 200319475328460070872 No Iranian Research Institute for Information Science and Technology (IranDoc), Tehran, Iran MolukoSadat Hosseini Beheshti beheshti@irandoc.ac.ir 200319475328460070873 200319475328460070873 No Iranian Research Institute for Information Science and Technology (IranDoc), Tehran, Iran Fatemeh Sheikhshoaei fashoaei@sina.tums.ac.ir 200319475328460070874 200319475328460070874 Yes Department of Medical Library and Information Sciences, School of Allied Medical Sciences, Tehran University of Medical Sciences, Tehran, Iran
