Citation indeks ve citation analizi: Enformetrik bir model çalışması
Scientific articles, published in English, countries is being complied under "Citation Indexes" with their references in developed countries. These indexes take into consideration only a small amount of the scientific studies realized in developing countries. Therefore, under such a situation it is extremely difficult to determine the level of contribution to the information produced and developing science at universal level by countries like Turkey. These types of informetric studies are mainly executed by means of evaluation of the publications in the English citation indexes of authors of a certain subject in our country. Whereas, we believe that it is impossible to execute a healthy study, aiming at measuring of the information produced in Turkey and scientific evaluation of authors and publications, without forming Turkish citation indexes. For this reason, the first objective of our study is to make it clear that it is necessary to compile the scientific studies, published in Turkish, together with their references in a source of citation index type. In our opinion it shall be possible to realize informetric studies, covering all fields öf science with the formation of this kind of index. In order exemplify the manner in which this kind of an application can be realized in any field of science, seventeen doctorate thesis have been selected from the librarianship literature in our study. Articles in the bibliography of the theses and their publications have been complied in a database and synchronic citation analysis has been realized. Thus the publications utilized in these thesis' s have been classified into three categories in accordance with the Bradford Law. It has been determined that the "Türk Kütüphaneciler Derneği Bülteni (Turkish Librarianship Association Bulletin), which was in the core category, is the publication utilized the most in 302the thesis studies of the Turkish Librarianship. Other publications have been listed according to their level of significance in our study. When the breakdown of the articles according to the age factor is examined, we see that most of the citations do not include the publications of the recent years. On the other hand, according to the analysis results we see that the rate of article utilization in thesis' s is rather low. * Conclusively, as a result of our researches it is suggested informetric laws and models can be utilized in the determination of infrastructure requirements of our scientific policy in general and specifically of our information services.
