文献计量分析中的数据准备工作研究

Research on the Data Preparation of Bibliometric Analysis

数据准备工作是文献计量分析的基础,它主要包括数据采集和数据清洗两个方面。数据的准确性直接影响文献计量分析结果的客观性。通过几个检索案例对比分析发现,数据准备工作在文献计量分析研究中十分重要。研究者可从以下4个方面改进数据准备工作:分析信息需求,选用合适的检索方法;掌握数据库的使用方法;尽量提高查全率,及时补充遗漏数据;删除误检数据。

The data preparation is the foundational work of bibliometric analysis,it mainly includes the data acquisition and data cleaning.The accuracy of date affects directly the objectivity of bibliometric analysis results.Through the comparison of several retrieval cases,we find that the data preparation is very important in bibliometric analysis.Researchers could improve the data preparation work through four aspects： selecting the appropriate retrieval method through analyzing information needs;mastering how to use the database;advancing recall ratio,replenishing the missing data;and removing the false data.
