Among the 8283 data collected, the highest number of citations was only 85, 11 papers were cited more than 50 times, 386 papers were cited more than 10 times, and 3701 papers were not cited, accounting for 44.68% of the total. The large proportion of papers without citations is related to the short years of publication of papers in the sample. The following figure shows the distribution of citation frequency (Figure 1), from which we can see that the number of citations in the sample is mainly distributed below 5 times, and there are no citations over 100 times.

The citation frequencies, Altmetrics scores and indicators of 8283 data were extracted and imported into SPSS software for descriptive statistical analysis, and the results are shown in Table 1.

Table 1 lists only those metrics with coverage (coverage refers to the number of papers for which the valid value of a metric is not equal to 0 as a percentage of all papers) of 0.1% or more. The table shows the utilization of these metrics and where the influence of the LIS field comes from. 8283 articles of Altmetric

contain metrics, Mendeley is mentioned by users in 95.79% of papers, mentioned in Twitter, Dimensions, Facebook, Blog, News, Google, etc. The percentage of papers mentioned by users was 81.15%, 63.77%, 55.32%, 13.24%, and 10.48%, respectively, while the coverage of papers in the field of LIS by metrics such as News, Google, Policy, Wikipedia, Social News, Review Sites, Video, F1000, Patents, and Q&A was below 10%, and the coverage of microblogs, LinkedIn, Pinterest, the course syllabi and reading bibliographies had zero metrics and were not mentioned. Looking at the mean value of these metrics, the mean value of cited frequency is 2.22 and the mean value of Altmetrics score is 7.95, where the mean value of Mendeley is 26.85, Twitterr is 9.06, and Dimensions is 3.30. Only 55.32% of the 8283 articles are cited, which may have something to do with. This may be related to the fact that all these data were published in recent years, and it can also show that it is far from enough to evaluate the influence of an article only by the indicator of the number of citations. In this paper, we analyze the indicators with high coverage to establish a comprehensive impact evaluation system, and then identify the research hotspots in the field of LIS by identifying the high impact research literature.

Six indicators (citation frequency, Mendeley, Twitter, Dimensions, Facebook, Blog) with a coverage rate of 10% or more were selected to establish the comprehensive influence evaluation index system of the paper, and the data of the corresponding indicators of the paper were imported into SPSS for factor analysis. The results are shown in Table 2: the correlation between citation frequency and Mendeley and Dimensions is high, reaching 0.676 and 0.940, respectively, and the correlation with Twitter, Facebook, and Blog reaches 0.143, 0.122, and 0.137, respectively. the probability of two-sided test is 0.000, which is less than

^aDeterminant = 0.038.

0.001, that is, the correlation reaches significant at 0.001 level to reach significant correlation.

KMO (Kaiser-Meyer-Olkin) is an indicator used to compare simple correlation coefficients and partial correlation coefficients among variables. the KMO statistic takes values between 0 and 1. the closer the KMO value is to 1, the stronger the correlation between variables and the more suitable the original variables are for factor analysis. The KMO value in Table 3 is 0.658, which is greater than 0.06, indicating that the bias correlation between the six indicators is strong and the original variables are suitable for factor analysis; the Bartlett sphericity test for significance indicates that the six variables are significant among each other.

As seen in Table 4, the commonality of all variables is high except for Facebook.

Then the data were subjected to principal component analysis, there are two factors and the variance contribution rates are 44.54% and 25.08%, respectively, and the cumulative variance of these two components is large, reaching 69.61%, so two common factors can be extracted; then the maximum variance method was selected and the factors were orthogonally rotated to obtain the factor loading matrix (Table 5) and the component score coefficient matrices (Table 6):

From the factor score coefficient matrix, we can obtain the formula for the two factor score functions for the dissertation evaluation.

F academic = 0. 364C + 0. 345M − 0.0 34T + 0. 378D − 0.0 35F − 0.0 41B

F social = 0.00 2C − 0.0 64M + 0. 5 00 T − 0.0 24D + 0. 4 0 5F + 0. 471B

(Initials are used instead of individual variable names, where C indicates M for Mendeley, T for Twitter, D for Dimensions, Cited frequency, F for Facebook,

and B for Blog)

Extraction method: Principal component analysis.

According to the loading weights of each factor 44.54% and 25.08% to obtain the combined influence score of the paper:

F composite = ( F academic × 0. 4454 + F social × 0. 25 0 8 ) / 0. 6962

The two-dimensional scale is an analysis method that selects two classification dimensions and draws a four-quadrant diagram, which is deepened from the “Boston matrix analysis” method and can be used to analyze the level and status of the field. After obtaining the impact score of the paper, the X-axis indicates the social influence F_society, which indicates the social attention and influence of the paper in the Web environment; the Y-axis indicates the frequency of citations F_academic, which indicates the academic research level of the paper. The two-eight law of literature prevailing in academia was chosen to be applied, and 20% of the papers with social influence greater than 0.35 were obtained with the X-axis with 0.35 as the benchmark cut-off; 20% of the papers with academic influence score greater than 0.24 were obtained with 0.24 as the benchmark standard cut-off, and the sample papers were put into the two-dimensional coordinates (Table 7).

Finally, four quadrants were obtained.

1) “Hot areas”: located in the first quadrant of the figure. This field is characterized by high social media and academic influence. The authors in this area are all highly accomplished academics, leading scholars and leaders in the field of LIS. The research content of “hot fields” is usually the hot spot and the frontier of research in this field, so the citation frequency and altmetric index are high.

2) “Classic fields”: located in the second quadrant of the graph. This field is characterized by high academic influence and a high number of citations, but it is less mentioned on social media. I think the authors in this field have high prestige themselves, but are not active enough in academic communication networks.

3) “Marginal Fields” is located in the third quadrant of the graph. Authors in this field have some minor influence in academic and social networks. Most of the young researchers in the field of figure of affection are authors in this quadrant position, who are more active in academic social media and have less academic achievements, and their academic and social influence will slowly increase with time in the future.

4) “Emerging field”: located in the fourth quadrant of the figure. This research area is more active on academic social networks, but is less frequently cited. This area may be an emerging area of research that has not yet been discovered by most scholars.

The 4141 data were imported into VOSViewer, and the data were analyzed by Bibliographic coupling (Bibliographic coupling), the type of analysis was Publications (Sources), and the threshold value was selected as the minimum of 5 published papers, and the following Figure 2 was obtained.

As can be seen in Figure 2, the main journals from which the articles with high Altmetrics scores come. The top 10 high-impact journals are Scientometrics (354 articles), Journal of the american medical informatics association (300 articles), Qualitative health research (176 articles), telematics and informatics (154 articles), journal of the association for information science and technology (153 articles), journal of informetrics (147), international journal of information management (127), journal of health communication (125), profesional de la informacion (103), and journal of academic librarianship (102). The total altmetrics scores of the journals (top 40) and six indicators (frequency of citations, Mendeley, Twitter, Dimensions, Facebook, and Blog) were summarized in Table 8. Six journals are ranked in the top 10 by AAS; three other journals are ranked in the top 20, 11th, 12th and 18th respectively; only one journal, international journal

of information management, is ranked relatively low, 32nd.

These six indicators (frequency of citations, Mendeley, Twitter, Dimensions,

Facebook, and Blog) were then clustered using SPSS to obtain a clustering tree diagram (Figure 3).

From the figure, it can be seen that journals in the field of LIS communicate online mainly on the platform of online literature management tools and academic social Mendeley; secondly, journals in the field of LIS are often mentioned on Twitter; Blog, Facebook, Cited frequency, and Dimension indicators all score relatively Blog, Facebook, Cited frequency, and Dimension indicators are all relatively low.

These journals are then placed in a two-dimensional quadrant: with AAS as the X-axis and citation frequency as the Y-axis. The journals located in the fourth quadrant are basically in emerging fields, and these journals include: Insights: the UKSG journal, Archives & Manuscripts, Ethics & Information Technology, Information Technology & Libraries, Journal of Library Administration, JLIS.it, Archival Science, Cataloging & Classification Quarterly.

Journals located in the fourth quadrant of emerging fields published a total of 443 articles on LIS, and the highest AAS of these articles was 197, with high activity on academic social networks; the highest citation frequency was 10, with fewer citations, which is related to the recent publication of articles in emerging fields. However, this field should be an emerging area of LIS research, which has

not been discovered by most scholars and will most likely become a research hotspot in the future.

Using Citespace software, the data of these 443 papers were analyzed to reveal the research hotspots in the field of LIS, with the node type selected as “Reference”, the time zone span (Slice) set to 1 year, the data filtering set to Top50, the pathfinding network algorithm, and the overall network The results are shown in Figure 4.

Figure 4 has 178 nodes, forming six clearer clusters: intelligent system, archival intervention, case study, radical empathy, virtual reality, and algorithmic paranoia. For the above identification and findings, the content analysis of these clustered literature yielded the research frontiers in the field of LIS.

Frontier 1 intelligent systems consists of the clustered literature #0 intelligent system in the figure. With the research of artificial intelligence technology, Bryson, Joanna J, Gunkel, David J have argued that the design of intelligent systems should be combined with the design of ethical systems to design ethical AI and should be more patient in the face of AI to guide the norms [11] [12]. Johnson, Deborah Gr states that robots should not be treated like animals and that when

building robots one should consider where they are and where they fit in the physical, economic, legal, intelligence and ethical [13].

Frontier 2 archival intervention and case study Consisting of 3 clustered literatures #1 archival intervention, #3 case study, and #4 radical empathy, Wright,

Kirsten [14] discusses issues related to the display and use of historical language that is now seen as offensive. Taking the non-neutrality of archives, archival systems and documents as a starting point, he considers the role of archivists in maintaining and reproducing dominant power structures through archival descriptions. It also examines the implications of non-critical reproduction of historical language in archival descriptions, catalogs and the search for secondary sources. It considers the balancing act between reproducing that language and potentially causing offense and distress if the information is not displayed, which would not provide complete and accurate information. Lapp, Jessica M [15] explores how archival work, once considered mechanical, servile and invisible, can become powerful and disruptive, providing opportunities for political intervention and social change. Sutherland, Tonia examines the influence of anthropologist, dancer and choreographer Katherine Dunham on African wandering dance works through the intervention of archives, arguing that the reading of gestures as documents or records came to be used as a colonial archival practice, making the archive a cultural the beginning of expression that would otherwise render the extant Western archival practices invisible [16].

Lian, Zhiying [17] analyzed the sustainability of independent community archives in China and he classified three models of community archives in China. The first is the preservation of community archives in government-funded/ government-created museums or archives. The second place is where community archives are kept by academic organizations such as universities. The third is where communities create their own archives. The last model is very rare in China. He discusses the emergence and development of the PCMML, a museum of migrant workers’ culture and art in Picun, and the challenges it faces. He argues that the survival strategies of independent community archives in China depend on three dimensions: the community itself, the community, and the government. caswell, Michelle [18] and others see community archives as personal political sites, and they argue that the spatial archival metaphor needs to be transformed, and that community archives are personally and politically transformative spaces for the communities they represent and serve. douglas, Jennifer theoretically and methodologically focus on the individual in the archive, and they suggest that it is best to decide whether to consider a record as personal based on its creator rather than its creators [19].

Lowry, James approach displaced archives from a new perspective, using theories and concepts recently introduced in archival theory by Michelle Carswell, Anne Gilliland, and Marika Chifle: influence, imagined records and the impossible archival imagination and Radical Empathy. In his opening keynote address at the 8th International Conference on the History of Records and Archives in Melbourne, Australia, he first outlined archival displacement as a historical phenomenon, then focused on postcolonial cases and argued for a more comprehensive history of archival displacement during decolonization, further elaborating on the potential research agenda for displaced archives as a still under-researched area of archival research [20] [21].

Frontier 3 Virtual reality Consists of literature clustered by #6 virtual reality. Ramirez, Erick Jose [22] et al. argue that the design and use of certain kinds of virtual reality (VR) experiences in specific contexts may be unethical, and that almost-real experiences can raise ethical issues for VR technologies unique to the medium. Therefore, a higher level of ethical scrutiny should be applied to any VR scenario that may produce an almost-real experience. To mitigate this unique ethical risk, they propose the “equivalence principle”. This principle states, “If it is wrong to allow subjects to have certain experiences in reality, then it is wrong to allow subjects to have experiences in environments that are actually real.” They argue that such principles, although limited in scope, should be part of any risk analysis conducted by institutional review boards, psychologists, experience-oriented philosophers, or game designers who use VR technology in games.

Frontier 4 Algorithms Consisting of the literature on #7 algorithmic paranoia clustering. sheehey, Bonnie [23] examines the temporal operation of the power exercised by predictive policing algorithms in light of the recent emergence of predictive techniques in law enforcement to predict crimes before they occur. He argues that predictive policing exercises power through a paranoid style that constitutes a form of provisional government. Temporality is particularly relevant to understanding the ethical relationship of predictive policing because temporality is continuous with the historical racial practices of organizing, managing, controlling, and stealing time.
