Abstract: With the coming of data driven sciences, the importance of re-using scientific research data is increasingly significant. How to quantitatively measure the impact of the datasets, as well as the data authors, and data centers is particularly urgent. Based on the statistics of the data citation from 2014 to 2018 and the method of Data Impact Score (DIS) models, the DIS of each dataset among the 192 cited datasets published by the Global Change Research Data Publishing & Repository (GCdataPR) and the Geoscientific Data & Discovery Publishing System during 20142018 were calculated using the DIS model. Besides, the DIS of each author among the 565 dataset authors and two data publishing centers were also calculated using the DIS models. There are totally 324 citations with the DIS of 134.069,4 during 20142018. Taking 5%, 15%, 30% and 50% as the critical values, all the datasets were classified into Q1, Q2, Q3 and Q4 levels. As the result, 10 datasets were ranked into Q1 with the DIS above 6, 24 datasets were ranked into Q2 with the DIS between 2 and 6, 41 datasets were ranked into Q3 with the DIS between 0.22, and 117 were ranked into Q4 with the DIS less than 0.2. There were 28 data authors ranked into Q1, and the GCdataPR was ranked the top one of the data publishing centers. The DIS methodology can be used for more broad datasets from the data repositories or data publishers in national and international levels.

Keywords: big data; data impact score; statistics; data author; data center

1 Background

Global change and geoscience data are related to all spheres of the earth, multiple spatial-temporal scales (from global to regional and local, from instantaneous to monthly, yearly, …, historical and geological), and in different data formats(vector, raster or table based). The data is a necessary resource for global change, earth science research, and sustainable development. Dataset is a basic body of data publishing and dissemination, as well as the data citation. In order to promote the research data sharing and re-using, the Big Data Working Committee of the Geographical Society of China (BigData_WC/GSC) decided to have a quantitative measuring action with the Liu’s Data Impact Score (DIS) methodology[1] since 2018. Through quantitatively measuring with Data Impact Score, the first 5% and the first 5%15% of the most impact datasets are ranked into Q1 and Q2, respectively.

In early 2019, the BigData_WC/GSC had a call for dataset impact measuring based on the datasets published during 2014–2018. The aim of the call is to encourage open good-quality data to be reused by citation in the broad fields of earth system science and global change studies. The BigData_WC/GSC shall release the data impact ranking based on the data citation[2] census and DIS models.

The qualifications for the dataset, which can be archived in the data impact measuring database, are as follows:

(1) The contents of the dataset are relevant to the fields of global change or earth sciences;

(2) The dataset is already published with DOI (Digital Object Identifier) and archived in any of the regular members of World Data System[3], or National Data Center, or any qualified and registered data publishers;

(3) The dataset is openly accessible through internet; 

(4) The dataset was published from January 1, 2014 to December 31, 2018.

Any of the followings is eligible to submit his/her application:

(1) Dataset author: the dataset authors (the first author, corresponding author, or any of the co-authors) are eligible to submit the application for the dataset impact measuring;

(2) Data publisher: the data publisher is eligible to submit its application for all datasets published through it for the dataset impact measuring.

The deadline of the applications was May 15, 2019.

The Geographical Society of China will officially release the measuring datasets impact result at the 2019 Conference of the BigData_WC/GSC (September 21, 2019, Dalian)[4]

2 The Flowchart of Data Impact Assessment of Global Change and Earth System Science

The flowchart of data impact assessment of global change and earth system science is shown in Figure 1.

According to the process of data impact assessment of global change and earth system science in 2019, the first step is to identify each valid dataset, which will be measured, and then put it into the Assessment Sub-database; secondly, a comprehensive survey was conducted based on the dataset citation (including published title, author, journal, volume, year, DOI), and a Data Citation Sub-database was established; then, based on the Impact Factors (IF) of citing journals[5] collected, the citing journals’ IF Sub-database was established; finally, according to DIS model[1] and the above information, the DISdataset (2014–2018) was calculated.

Taking the first 5%, 15%, 30% and 50% of DISdataset (2014–2018) as the critical values, the Q1, Q2, Q3, and Q4 of DISdataset (2014–2018) were identified.

Based on the DISdataset (2014–2018) and DIS models[1] for measuring the data authors, funding agencies and projects, the author affiliations, and data publishers, the DIS for each of them was calculated separately.

3 Database Establishment for Measuring Impact of Published Datasets in 2019

The database for the published datasets impact measuring in 2019 consists of five tables, including:

(1) Valid datasets for impact measuring;

(2) Data citation information of each dataset;

(3) Impact Factors of each citing journal;

(4) DIS models for datasets, data authors, data authors’ affiliations, funding agencies, funding projects, and data publishers;

(5) DIS results and ranking for each of dataset, data authors, data authors’ affiliations, funding agencies, funding projects, and data publishers.

3.1 Valid Datasets for Impact Measuring (2014–2018)

There are 282 valid datasets for the data impact measuring among the 284 applications. Two datasets were not included, because no dataset was published along with the data papers.

The contents of dataset information include: dataset title, publisher, DOI, publication year, website, the authors, author’s affiliations, funding projects, data format, data size, data policies, data retrieval information, etc.

3.2 Data Citation Information of Each Dataset

For establishing the data citation sub-database for each dataset, the information of citing papers for each dataset from 2014 to 2018 was collected, including the title of dataset, title, DOI, and authors of citation paper, year of the paper published, journal title, journal ISSN, etc.

3.3 Impact Factors Sub-database of Each Citing Journal

The IF information of each citing journal in each year from 2014 to 2018 was collected to establish the IF sub-database for each citing journal.

3.4 DIS Model Sub-database

The DIS models are composed of several models, including:

(1) DIS model for dataset;

(2) DIS model for data publisher;

(3) DIS model for data author;

(4) DIS model for funding agencies;

(5) DIS model for funding projects;

(6) DIS model for ranking (Q1, Q2, Q3, Q4).

3.5 DIS and Ranking in 2019 (Based on Data During 2014–2018)

The DIS results and ranking database include:

(1) DIS ranking for dataset in Q1, Q2, Q3, Q4;

(2) DIS ranking for data publisher;

(3) DIS ranking for data author Q1, Q2, Q3, Q4;

(4) DIS ranking for funding agencies;

(5) DIS ranking for funding projects.

4.1 Dataset Impact Score (DISdataset)

Among the 282 datasets from two data publishers, which were valid application for data impact measuring, 192 datasets were cited, with a citation rate of 68.09%. The authors of these datasets were 565 individuals.

The method of calculating the DIS of each dataset for five years is based on two steps. The first step is to calculate the DIS for each of the datasets each year[1] and then summarize the DIS for five years during 2014–2018. The model of DIS for a dataset for five years is shown in the following formula:

                      (1)

where DISDy is the dataset impact score in y year.

4.2 DIS Summary for the 192 Cited Datasets in Five Years (2014–2018)

The DIS for the 192 cited datasets in five years (2014–2018) is summarized in Table 1.

6 DISp Ranking

Based on the statistics of datasets published by each data publisher and the DISdataset of each dataset, the DISp for each publisher in 5 years was calculated. The calculation method is as follows:

                           (2)

where DISp is the sum of DIS in 5 years for the data publisher, and n is the number of dataset published from 2014 to 2018. The DISi dataset was the impact score of the ith dataset from 2014 to 2018.

Figure 2  Prof. Liao Xiaohan, Chair of BigData_WC/GSC and Prof. Lu, Huayu, Vice President of GSC presented the certificates to each of the datasets and data authors in Q1 (September 21, 2019, Dalian, China)

According to the above calculation results, the Global Change Research Data Publishing & Repository (GCdataPR)[5] (DOI: 10.3974/) co-operated by the Institute of Geographic Sciences and Natural Resources Research (IGSNRR), CAS, and the Geographical Society of China (GSC) published 161 datasets, with credited DISp of 416.001,9, while the Geoscientific Data & Discovery Publishing System[6] (DOI: 10.23650/) operated by the National Geolog-ical Archive and superintended by the Ministry of Natural Resources of P. R. China, published 31 datasets, with the DISp of 30.048,5 (Table 6).

8 Discussion

The practice of data impact measuring with the DIS methodology for global change and earth system science data in 2019 shows that the quantitative assessment of the data impact can reach to every dataset, data author, and data publisher. There is a phenomenon that the data citation is normally delaying a few years than that of discovery papers. From Tables 3 and 4, the two cases published by GCdataPR, either a single dataset or a data publisher, the citation delaying is at least 5 years. There may be several reasons. First, it may be that the data published is not well-known at its earlier stage, but it is more and more popular year by year. Second, the scientific achievements made by the dataset re-using are different from the scientific discovery. It requires a process of data re-application, re-integration and then discovery, which takes a longer time than the paper directly adopting the discovery viewpoints. Third, it is possible that data users are not very familiar with how to cite the dataset, and some of users mention their uses in acknowledgement instead of references. Because the data citation is a new specification, as time goes by, the data application and citation in standardization will increase.

As the current statistical data are all datasets published in China, according to the statistics of users’ source of download usage, the Chinese users are far more than that of international users. However, in terms of data citation, the number of citations of Chinese journals is less than that of English journals. This phenomenon indicates that Chinese users probably do not clear how to cite data in references, so they can’t be counted in the DIS model. Therefore, it is necessary to further strengthen the publicity and requirements of new regulation and scientific ethics to promote the standard data citation in China and the editors of each journal also need to strictly check and take the data citation as one of the important part of the paper review.

The peak of the data citations occurs in the last year of the 5-year statistics; does it happen in the fifth year or later? Does different datasets have different lag periods? How long could the data citation peak lag periods be? and when does the peak of data citation occur? It seems need more practice and take a longer time, as well as to have more sufficient data and cases to answer these questions.
