The evaluation of an article is an important issue for scientific research. A journal impact factor is used widely to evaluate the impact of the journals. An impact factor is considered as an influence measure of articles. Articles in a high impact factor journal tend to have strong impact on the wide research fields. However, this does not imply that they have big influence in a particular research area. Measuring the speciality and the generality of research results is not trivial task. The present paper proposes a generalized method to evaluate the influence of a journal with respect to a focused view. An empirical evaluation was conducted on "bibliometrics" related 10,186 articles.
