Brazilian Research Output in Education from 2007 to 2016

This dataset has been used to analyze publication practices of Brazilian researchers in Education in three different periods: [2007, 2009], [2010, 2012], [2013, 2016]. The dataset is composed of 4249 records, each of them containing information about a scientific journal in which faculty and students of Brazilian graduate programs in Education have published their work. In addition, each record also stores information about the number of articles published by the Brazilian Education community in each journal and its citation impact in a given period. The indicator chosen to represent the journal's citation impact has been Elsevier's SNIP. The records also store information from a Brazilian journal ranking system called Qualis, a classification made by the Coordination for the Improvement of Higher Education Personnel (CAPES), a governmental institution whose purpose is to coordinate efforts for the improvement of the quality of faculty and staff in higher education. The dataset comprises information about the publications by Brazilian researchers in Education including articles published in journals that were and were not indexed by SCOPUS.

The research questions that were answered with the analysis of the data were:

1) What was the distribution of publications in indexed and non-indexed journals in the three periods [2007, 2009], [2010, 2012], [2013, 2016]?
2) What was the distribution of publications according to country of publication of the journals?
3) What was the citation impact of the publications in indexed journals in the three different periods?
4) Were there discrepancies between the classification of journals in the CAPES Qualis system and the citation impact provided by SCOPUS' SNIP?

It is important to highlight that the three periods considered in the dataset do not have the same number of years. This is because CAPES previously collected information for its evaluation of graduate programs every three years ([2007, 2009], [2010, 2012]), but it changed to four years in the last period ([2013, 2016]).

The final structure of the records of the dataset is detailed below.

- Publication period: year interval in which the article publications were made: 2007-2009; 2010-2012; 2013-2016
- ISSN_PRINT: unique identifier of the printed version of the journal in which the article publications were made
- ISSN_ONLINE: unique identifier of the online version of the journal in which the article publications were made
- Title: journal title
- Number of articles: total number of articles published in the journal in the given period
- SNIP: Elsevier SNIP citation impact computed for the journal in the given period
- Qualis: classification rank of the journal at the given period, with values ranging from (highest to lowest): A1, A2, B1, B2, B3, B4, B5
- Country: country of publication of the journal

本数据集被用于分析巴西教育领域研究人员在三个不同时期（[2007, 2009]，[2010, 2012]，[2013, 2016]）的出版物实践。数据集由4249条记录组成，每条记录均包含巴西研究生教育项目中的教师和学生发表在其上的科学期刊的信息。此外，每条记录还存储了巴西教育社区在每个期刊上发表的文章数量以及在该特定时期内的引用影响。用以表征期刊引用影响的指标为Elsevier的SNIP指标。记录还包含了巴西期刊排名系统Qualis的信息，该系统由高等教育人员质量提升协调委员会（CAPES）进行分类，CAPES是一个旨在协调提升高等教育教师和员工质量水平的政府机构。数据集涵盖了巴西教育研究人员发表的作品信息，包括在SCOPUS是否索引的期刊上发表的文章。通过数据分析，解答了以下研究问题：

1) 在三个时期[2007, 2009]，[2010, 2012]，[2013, 2016]中，索引和非索引期刊的出版物分布情况如何？
2) 根据期刊的出版国家，出版物的分布情况如何？
3) 在三个不同时期中，索引期刊的出版物引用影响如何？
4) CAPES Qualis期刊分类与SCOPUS SNIP提供的引用影响之间是否存在差异？

值得关注的是，数据集中考虑的三个时期所包含的年数并不相同。这是因为CAPES先前每三年收集一次其研究生项目评估的信息（[2007, 2009]，[2010, 2012]），但在最后一个时期（[2013, 2016]）改为每四年一次。数据集记录的最终结构如下。

- 出版时期：文章发表年份区间：2007-2009；2010-2012；2013-2016
