Coverage of DOAJ journals' citations through OpenCitations - Result DataSet

The dataset contains: by_journal.json: a file containing all information extracted by Open Citations about DOAJ journals divide by year and journal name. Inside the file, the metadata about the journal are: ISSN EISSN number of articles overall in the journal subject(s) number of citations received number of citations done ratio between citations done and received number of citations received from DOAJ journals number of citations done to DOAJ journals ratio between citations done to and received from DOAJ journals. normal.json: a file containing all information extracted from Open Citations about DOAJ journals divided only by year. Inside the file, the data by year are: number of citations received. number of citations done. ratio between citations done and received. number of self-citations made by DOAJ inside Open Citations. ratio between the self-citation and the total citations received and done by DOAJ. errors.json: a file containing the count of all errors obtained from computations. Inside the file: errors about records that don't have any specified date (null dates). errors about records that have impossible dates (wrong dates). errors about articles that don't have any specified Dois. errors about Open Citations records that don't have any Dois in the citing or cited fields. DOAJ_metrics.json: a file containing metrics about DOAJ and Open Citations, obtained by computations. Inside the file are these fields: number of journals with dois. number of articles which have been processed during computations. number of used Dois. All dois (with no repetition) which are used for the adding journal operation. number of repeated Dois. All dois which are repeated inside the same or in another journal. number of accepted Dois. All articles (with repetition) which have both a defined journal and a defined doi.本数据集包含以下文件： 1. by_journal.json：该文件收录了由开放引用（Open Citations）从按年份与期刊名称分组的开放获取期刊目录（DOAJ）期刊中提取的全部相关信息。文件内包含的期刊元数据包括：国际标准刊号（ISSN）、电子国际标准刊号（EISSN）、期刊总发文量、主题分类、总被引次数、总施引次数、施引-被引比率、来自DOAJ期刊的被引次数、向DOAJ期刊的施引次数、向DOAJ期刊施引与来自DOAJ期刊被引的比率。 2. normal.json：该文件收录了由开放引用（Open Citations）从仅按年份分组的DOAJ期刊中提取的全部相关信息。文件内按年份统计的数据包括：总被引次数、总施引次数、施引-被引比率、DOAJ期刊在开放引用（Open Citations）库内产生的自引次数、自引与DOAJ总施引被引总量的比率。 3. errors.json：该文件统计了计算过程中产生的全部错误类型与数量。文件内包含的错误类别包括：无指定日期（空日期）的记录错误、日期无效（错误日期）的记录错误、未指定数字对象标识符（DOI）的文献错误、开放引用（Open Citations）记录中施引或被引字段未包含DOI的错误。 4. DOAJ_metrics.json：该文件包含通过计算得到的DOAJ与开放引用（Open Citations）相关指标。文件内包含以下字段：带DOI的期刊数量、计算过程中处理的文献总量、使用的DOI总数、用于添加期刊操作的所有无重复DOI、重复DOI总数、在同一期刊或跨期刊内出现重复的所有DOI、被接收的DOI数量、同时包含明确期刊信息与明确DOI的所有文献（含重复记录）。
