One of the most important factors challenging the issue of "information storage and retrieval" in the Internet environment is the lack of control on authorities, including subject authority control. The present research aims at examining the feasibility of subject authority control of Persian medical databases available on the Net. Based on research methodology, we have chosen 50 keywords by random from keywords utilized by users who searched databases for articles. In the pre-test stage, these keywords were searched in Iranmedex, a database for Persian medical articles. The keywords utilized by database users were compared with Persian medical thesaurus and those which exactly matched with the thesaurus words were entered in a designed database using Microsoft Access software. In the next stage, we entered these authorized keywords in Iranmedex. Findings of new search sessions revealed that control of authorities makes information retrieval more precise and accurate. It also prevents false drops. The research findings can be used for modifying the process of information storage and retrieval on the Internet. The research concludes with a model for applying thesauruses as authority control tools for other databases available on the Internet.
