Title: A quality filtering method for biomedical literature

Abstract: The scientific literature has become too vast to comprehend, the need for quality filtering was introduced. In general the act of citing is an expression of the importance, thus the citation frequency has been used as a quality measure. Since the review articles are usually produced by the experts in the given subject, the quality filtering method using the citation frequency of review articles was used to cope with the vast amount of literature. However, there are some defects in using citation frequency as a quality measure, that is, the validty of citation and the equal value of every citation. Moreover, the review articles themselves are not of equal quality. The quality filtering method proposed in this study is designed to improve the defects of citation frequency as a quality measure.

In applying the theory of Markov chains, the generation of citation was made the probability that each author/journal is going to be cited after long strings of citation was obtained. The one who has high probability can be considered as good quality in the given subject. The filtering method using the citation frequency of review articles are used as the intermediate filter. The probability that the author/journal is going to be cited by the member of the group was obtained the nth power of the probability transition matrix. the ranking by the limiting probability U sub k differs from the intermediate filter and R.I.F.

It is useful for the scientist who needs the contracted list of good quality authors and journals for his interest. When this method is applied to the subject along with intermediate filter, this can be good quality filtering method.
