چکیده:
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, i.e. 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
randomly chosen 50 keywords utilized by users searching databases for
articles. In the pre-test stage, these keywords were searched through
Iranmedex, a database for Persian medical articles. Comparing them with
Persian medical thesaurus, those keywords exactly matched to the thesaurus
words were entered in a designed database using Microsoft Access software.
Then, we entered these authorized keywords in Iranmedex. Findings of new
search sessions revealed that control of authorities on the one hand, makes
information retrieval more precise and accurate and, on the other 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 at Internet.

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 randomly chosen 50 keywords utilized by users searching databases for articles.
Keywords: Information Storage and Retrieval, Persian Medical Databases, Iranmedex, Authority Control, Persian Medical Thesaurus, False Drops.
In the present study, we examined the issue of "authority control" in the Internet environment by concentrating on a significant Persian medical database, Iranmedex.
Designers of websites, databases and search engines can use librarians' solutions and experiences in order to provide a useful environment for access to digital information through the Internet.
Using authority control tools for Persian resources is one of the solutions and an example of the way Internet information providers can employ for retrieval of more relevant information by users.
Conclusion and Suggestions The major findings of the present research largely confirmed that there is a difference between retrieving needed information from Persian medical databases by controlled and free keywords.
It should be noted that by authority control we can help to increase quality of databases and provide users with their needed/relevant information.
All Persian medical databases make use of Persian medical thesaurus as a subject authority control to index their information.
