Abstract

This article presents a study of the average number of excess citations of papers in the h-core, denoted as e²/h and the ratio between the e-area and the h-area, denoted as e²/h². Real-world citation data from different countries are studied. It is found that at the country level, a small set of publications generate a disproportionately large amount of citations. Although different countries have different e²/h² values in different fields, average e²/h² values are all above 1. The e²/h values vary widely between fields, reflecting the general citation density in these fields. For cumulative data e²/h² and e²/h values each converge quickly. Neither a shifted Zipf nor an exponential model could fit the data.

h指数与超额报价关系的初步研究/ Hirsch指数(h指数)与超额报价关系的初步研究

本文研究了h核心论文的平均超额被引次数，记为e2/h, e面积与h面积之比记为e2/h2。研究了来自不同国家的真实世界引文数据。研究发现，在国家一级，一小部分出版物产生了不成比例的大量引用。虽然不同国家在不同领域的e2/h2值不同，但平均e2/h2值都在1以上。不同领域的e2/h值差异很大，反映了这些领域的普遍被引密度。对于累积数据，e2/h2和e2/h值收敛很快。平移Zipf和指数模型都无法拟合这些数据。

期刊介绍： The Canadian Journal of Information and Library Science is recognized internationally for its authoritative bilingual contributions to the field of information science. Established in 1976, the journal is dedicated to the publication of research findings, both in full-length and in brief format; reviews of books; software and technology; and letters to the editor. The editorial policy of the journal is to continue the advancement of information and library science in both English and French Canada by serving as a forum for discussion of theory and research. The journal is concerned with research findings, understanding the issues in the field, and understanding the history, economics, technology, and human behaviour of information library systems and services.
