中文摘要：

学科领域内的核心作者群极大地影响着学科的发展方向及发展速度，其成熟度是衡量学科发展是否成熟的重要指标。近年来知识发现成为信息资源管理的热点问题，为探究国际知识发现研究领域核心作者群的成熟度，本文以 Web of Science 平台 SSCI 和 SCI 数据库1993-2014年知识发现研究领域内的2723篇文献为研究对象，在运用普赖斯定律对核心作者群进行初步筛选的基础上，选用作者发文量与作品被引率的双重指标构建了综合指数评价体系最终确定377位核心作者，并对形成的核心作者群网络进行结构成熟度、网络关联成熟度分析。研究结果显示，国际知识发现研究领域已经培育了一支强大的核心作者队伍，但部分核心作者发文量与被引率之间存在错位现象，此外研究的国别发展不均衡现象较为严重。

英文摘要：

In certain research field, core author group can extremely influence the direction and development speed of this subject, so its maturity is an important index to evaluate the maturity of certain subject. In recent years, knowledge discovery has become a significant hotspot in information resource management. To explore core author group＇s maturity in international knowledge discovery research field, this paper chooses 2723 literatures about knowledge discovery from WOS within time span 1993-2014 as research subjects. Firstly, candi-date core authors are selected by applying Price＇s law. Then we construct a bi-index evaluation system by combining authors＇ publishing quantity and their citation quantity together to evaluate the candidate core author group and 377 core authors are confirmed finally. After that, two types of maturity, one is the core author group＇s structure maturity and the other is the core author group＇s relevance maturity, are analyzed. The result shows that a powerful core authors group has formed, but there exists mismatch between the quantity and the cited rate in some core authors＇ publication. In addition, imbalance of the research on knowledge discovery widely exists among different coun-tries.
