Abstract After three rounds of rigorous evaluation of core journals in gastroenterology and hepatology conducted by the Reference Citation Analysis (RCA) editorial team of Baishideng Publishing Group (Baishideng), the RCA database of Baishideng officially released the 2022 Journal Article Influence Index (2022 JAII) of 101 core journals in gastroenterology and hepatology, for the first time. The list of 101 core journals can be found at: https://www.referencecitationanalysis.com/Search-Journal. Among them, the highest 2022 JAII is 48.014 and the lowest is 3.900. This article highlights the top 20 journals, describes the calculation method for the 2022 JAII, the evaluation process, and the inclusion principles for journals in the RCA.These steps are the underpinning of the RCA’s empirical journal academic evaluation service by which the digital platform addresses the needs of authors to select reliable journals for submission, readers to select high-quality literature for reading, and editors to track their own journal citation performance. As such, the RCA core journal list will serve as a useful Find-a-Journal tool. Any interested party is welcome to use this journal list and recommend it to their peers.

RCAis an artificial intelligence technology-based open multidisciplinary citation analysis database. It was carefully designed to lead the development of wisdom, knowledge innovation, and emerging disciplines[1]. As such, the functions ofRCAinclude: Find an Article (54753299), Find a Category (254),Find a Journal (14087), Find a Scholar (631), and Find an Academic Assistant (15).RCAupdates its list of journals daily, according to relevant data including total number of articles, total citations, and theJAII.RCAacquires newly released abstracts and references from Crossref and adds them to theRCAdatabase weekly.RCAalso acquires abstracts and references released within the calendar year from Crossref and adds them to theRCAdatabase monthly, and then updates the total number of articles, citations, andJAIIaccordingly. Herein, we introduce the top 202022JAIIfrom the total 101 core journals in the field of gastroenterology and hepatology included inRCA, the calculation method for the 2022JAII, and the evaluation process and the inclusion principles ofRCAjournals.

The mission ofRCAis to provide a high quality academic article evaluation service platform for various categories. At present, there are many evaluation methods for academic articles, but their calculation methods are complicated. TheRCAis a new method of evaluating the quality of academic articles,which allows academic evaluation of journals, scholars, institutions, drugs, medical devices, and publishers based on theJAIIof each article in the citation analysis database, thus greatly enriching the academic evaluation systems across different disciplines and guiding the healthy development of the academic community[2].

OPENNESS AND TRANSPARENCY OF RCA EVALUATlON

RCAis unique in its objective, impartial, fair, and transparent release of citation analysis data of important academic journals to authors and readers, including evaluation data, evaluation indices,evaluation methods, and evaluation results, in order to ensure the reliability of academic evaluation[2].

CALCULATlON METHOD FOR 2022 JAII

The 2022JAII, calculated as Total citations/Total articles, is not a 2-year or 5-year average of citations,but is an average of citations for all articles since the journal was assigned its DOI number. Article types are not only limited to original articles and review articles, but for all types of articles. In this way, it is a more objective, fair, and transparent calculation of the academic influence index of an academic journal.Furthermore, the journal list itself is evaluated dynamically, its bibliographic metrics being updated daily, including total number of articles, total citations, andJAII[2].

EVALUATlON PROCESS OF RCA JOURNALS

The journals included in theRCAcore journal list need to undergo three rounds of strict evaluation. The evaluation process is as follows[2]:

First-round evaluation:Verify the basic information on the journal, including Journal Name,Abbreviated Title, Print ISSN, Online ISSN, Language, Category, Peer-Reviewed Journal, Ownership,Publisher, Journal Website, Editorial Board Members, Submit a Manuscript, and Indexed by.

Second-round evaluation:Verify the activity of the journal, including Total Articles, Total Citations,Cited by in F6Publishing, and theJAII.

Third-round evaluation:Based on the reliability of journal information, the activity of publication data,whether the journal is a peer-reviewed journal or not, andJAII, the editorial team evaluates every journal, makes the decision to accept or reject the journal, and creates a list of core journals by discipline.The function of the list of core academic journals is to classify journals according to categories and rank them according to various bibliometrics, including Total Views,JAII, Total Citations, Cited by in F6Publishing, Total Articles, and Number of Years.

lNCLUSlON PRlNClPLES OF RCA JOURNAL

TheRCAeditorial team of Baishideng conducted three rounds of rigorous evaluation on core journals in gastroenterology and hepatology. The resultantRCAcore journal list for the field of gastroenterology and hepatology includes a total of 101 journals, among which the highest 2022JAIIis 48.014 and the lowestJAIIis 3.900, the highest total number of citations is 1711173 and the lowest is 698, and the highest total number of articles is 46037 and the lowest is 133. TheRCAcore journal list does not include any journals with aJAIIlower than 3.0. We implement dynamic evaluation inclusively for theRCAcore journal list. Evaluation is initiated once anRCA-nonincluded journal receives aJAIIover 3.0. Similarly, if a journal included in theRCAcore journal list receives aJAIIlower than 3.0, it will be excluded[2]. TheRCAcore journal list is designed by publishers, scientific editors, and engineers for use by readers,authors, and editorial offices, and is free-of-charge to users.

Upon completion of the three rounds of rigorous evaluation on core journals in gastroenterology and hepatology by theRCAeditorial team, all data in each journal are organized for public consumption according to category rank, including the 2022JAII, total citations, cited by in F6Publishing, total articles, and the 2021 Journal Impact Factor™. All information in each journal, including Journal Name,Print ISSN, Online ISSN, Language, Free Access, Peer-Reviewed Journal, Ownership, Publisher, Journal Website, Editorial Board Members, Submit a Manuscript, and Indexed by are made available inRCA.Moreover, the citations of each journal can be then ranked inRCAby theImpact Index Per Article, Cited by in Crossref, and Cited by in F6Publishing parameters. Results analysis available for each journal includes Year Published Analysis, Article Type Analysis, Journal Title Analysis, and Category Analysis.The references of each journal are also refined by Year Published and Article Type. Each reference’s citation information is displayed, including PMID, DOI, Cited by in Crossref,Impact Index Per Article,RCA, and Track Full Text[2].

She went and sat down by her sisters, showing them a thousand civilities,49 giving them part of the oranges and citrons50 which the Prince had presented her with, which very much surprised them, for they did not know her. While Cinderella was thus amusing her sisters, she heard the clock strike eleven and three-quarters,51 whereupon she immediately made a courtesy to the company and hasted away as fast as she could.

CONCLUSlON

The ultimate purpose ofRCAis to provide an open, objective, fair, and reliable academic evaluation service platform for readers, authors, and journal editors. TheRCAjournal academic evaluation service platform is designed and actively maintained to address the needs of authors to select reliable journals for submission, readers to select high-quality literature for reading, and editors to track their own journal citation performance. TheRCAcore journal list itself will serve as a useful Find-a-Journal tool.Any interested party is welcome to use this journal list and recommend it to their peers.
