Academia.edu: Social network or Academic Network?

Investigating users' sustained information seeking on academic social networking sites

Purpose

This study aims to investigate motivators, mediator and moderator of users' sustained information seeking on academic social networking sites (ASNSs).

Design/methodology/approach

Drawing upon the expectancy–value theory and related information-seeking literature, the study developed a theoretical model to explain why and how users intend to continue seeking information on ASNSs. Thereafter, a field survey with 385 participants was conducted to test the model. Finally, a content analysis of participants' post-survey feedback was performed to complement the model test results by showing more fine-grained findings.

Findings

Results suggest that information usefulness and information adoption (IA) are significant to users' sustained information seeking on ASNSs, while users' satisfaction with ASNSs may play a mediating role in the relationship between information usefulness and sustained information seeking. Additionally, self-efficacy for critical thinking (SCT) weakens the impact of IA on users' satisfaction with ASNSs. The post-survey feedback analysis indicates that information usefulness is more critical to sustained information seeking for users with high SCT, whereas IA becomes more crucial to users' satisfaction with ASNSs and sustained information seeking for users with low SCT.

Originality/value

Although the extant literature has distinguished between information seeking and sustained information seeking, empirical research into users' sustained information seeking on ASNSs is limited. The study fills this gap by proposing and validating relevant factors and the boundary condition of users' sustained information seeking.

Exploring the factors influencing continuous usage intention of academic social network sites

Purpose

Academic social network site (ASNS) is a new form of academic service in the social media age, and the study of ASNS user behavior is of great significance to academic librarians due to its recent popularity. This research explores the influencing factors of the continuous usage intention of ASNSs.

Design/methodology/approach

A survey of academics in China was conducted, and 361 responses were collected and analyzed with a structural equation model, which involves satisfaction, continuous usage intention, expectation confirmation, perceived usefulness (PU), social identity, referent network size and perceived interactivity (PI).

Findings

Satisfaction, expectation confirmation, PU, referent network size, social identity and PI significantly impact continuous usage intention. Satisfaction is a mediating variable by which expectation confirmation, PU, referent network size, social identity and other influencing factors affect continuous usage intention. Expectation confirmation and referent network size are two endogenous variables that can explain and predict the continuous usage intention of ASNSs.

Originality/value

Existing research does not consciously distinguish between adoption, use and continuous use, and only scant studies have conducted empirical research. Further, despite the widespread ASNS usage in China, Chinese scholars' studies are few, as existing studies have mainly focused on users of the UK, the US and India.

Competitive exposure and existential recognition: Visibility and legitimacy on academic social networking sites

Over the past decade, academic social networking sites, such as ResearchGate and Academia.edu, have become a common tool in academia for accessing publications and displaying metrics for research evaluation and self-monitoring. In this conceptual article, we discuss how these academic social networking sites, as devices of evaluation that build on both traditional values, objects, and metrics in academic publishing and on social media logics and algorithmic metrics, come to fulfil a need in the current academic (publishing) ecosystem. We approach this issue by identifying key affordances that arise in the interaction between platform and user. We then position these affordances in relation to potential needs of academics in today’s publishing landscape by drawing on Hafermalz’s metaphor of the ‘fear of exile’, which provides an alternative way of understanding the importance of visibility in the networked world, as a combination of competitive exposure and existential recognition. We end by considering the grounds on which the platforms may be attributed some level of legitimacy. This is done in order to understand the inherent contradiction between the broad use of the platforms and the fact that their integrity has been questioned repeatedly. We seek an answer to a legitimacy for the platforms in the fact that a pragmatic, mutual benefit exists between them and the research community; a benefit that is enhanced by the audit society influencing current academia.

Characterizing response quantity on academic social Q&A sites: a multidiscipline comparison of linguistic characteristics of questions

Purpose

As academic social Q&A networking websites become more popular, scholars are increasingly using them to meet their information needs by asking academic questions. However, compared with other types of social media, scholars are less active on these sites, resulting in a lower response quantity for some questions. This paper explores the factors that help explain how to ask questions that generate more responses and examines the impact of different disciplines on response quantity.

Design/methodology/approach

The study examines 1,968 questions in five disciplines on the academic social Q&A platform ResearchGate Q&A and explores how the linguistic characteristics of these questions affect the number of responses. It uses a range of methods to statistically analyze the relationship between these linguistic characteristics and the number of responses, and conducts comparisons between disciplines.

Findings

The findings indicate that some linguistic characteristics, such as sadness, positive emotion and second-person pronouns, have a positive effect on response quantity; conversely, a high level of function words and first-person pronouns has a negative effect. However, the impacts of these linguistic characteristics vary across disciplines.

Originality/value

This study provides support for academic social Q&A platforms to assist scholars in asking richer questions that are likely to generate more answers across disciplines, thereby promoting improved academic communication among scholars.

Correlation between universities’ Altmetric Attention Scores and their performance scores in Nature Index, Leiden, Times Higher Education and Quacquarelli Symonds ranking systems

Objective:

Altmetrics are claimed to measure the scientific, societal, educational, technological and economic impacts of science. They have some of these dimensions in common with university ranking and evaluating systems. Their results are, therefore, expected to be partially convergent with the systems’. Given the importance of the scientific and non-scientific impacts of science, this study investigated the correlations of universities’ altmetrics with their total and dimensional scores in Nature Index, Leiden, Times Higher Education (THE) and Quacquarelli Symonds (QS).

Methodology:

Following a correlational design, it explored an available sample of the universities commonly ranked in the systems in 2017. The data were collected from online documents using checklists and analysed by the Spearman correlation. As Altmetric Attention Score (ASS) is efficient in that it integrates several indicators into a single one, it was used as the proxy of the universities’ social performance.

Findings:

The universities showed significant positive correlations between their ASSs and their performance scores on the total and dimensional levels, except for industry income in THE, with an insignificant correlation, and proportion of collaborative publication less than 100 km. in Leiden, with an inverse correlation. The correlations ranged from weak to marginally strong.

Conclusion:

The positive relationships between the universities’ performance and ASSs signified that there existed some similarities in what they measured. However, they were of weak-to-marginally strong powers, implying that the metrics differed in what they measured. The findings contribute to the existing knowledge by providing some evidence of convergence between university-level altmetrics and university performances in various dimensions.

Favoritism or equality: difference analysis of users' utilization of academic social networks for top research corporations

Purpose

As an important platform for academic communication and knowledge acquisition, academic social network (ASN) has attracted worldwide researchers. The purpose of this paper is to examine and compare the differences of corporation researchers in ASN utilization from the two aspects of social performance and academic performance.

Design/methodology/approach

Applying knowledge-based theory, this paper decoupled ASN into social network and academic network and measured utilization of users by social performance and academic performance. Hypotheses were proposed from the perspectives of research areas and corporate reputation. In the part of empirical research, the top 92 research corporations were selected as the sample, and relevant metric data from the member profile pages on ResearchGate was collected for comparing analysis to explore their utilization characteristics.

Findings

The results show that users of different research corporations have certain favoritism in their utilization of ASNs. Science and technology-oriented corporations are better in comprehensive social performance and academic quality. Science-oriented corporations are better at utilizing the interactive functions. However, neither social utilization nor academic utilization, technology-oriented corporations perform well.

Originality/value

This paper focuses on corporation researchers, who have started to embrace ASNs but whose behaviors were less studied. The research paradigm is an expansion and enrichment of the dual network decoupling theory in the field of ASN research. It also deepens the research on ASN utilization of corporation researchers and could give references for ASNs to improve service for corporation users in different research areas.

Could early tweet counts predict later citation counts? A gender study in Life Sciences and Biomedicine (2014-2016)

In this study, it was investigated whether early tweets counts could differentially benefit female and male (first, last) authors in terms of the later citation counts received. The data for this study comprised 47,961 articles in the research area of Life Sciences & Biomedicine from 2014-2016, retrieved from Web of Science's Medline. For each article, the number of received citations per year was downloaded from WOS, while the number of received tweets per year was obtained from PlumX. Using the hurdle regression model, I compared the number of received citations by female and male (first, last) authored papers and then I investigated whether early tweet counts could predict the later citation counts received by female and male (first, last) authored papers. In the regression models, I controlled for several important factors that were investigated in previous research in relation to citation counts, gender or Altmetrics. These included journal impact (SNIP), number of authors, open access, research funding, topic of an article, international collaboration, lay summary, F1000 Score and mega journal. The findings showed that the percentage of papers with male authors in first or last authorship positions was higher than that for female authors. However, female first and last-authored papers had a small but significant citation advantage of 4.7% and 5.5% compared to male-authored papers. The findings also showed that irrespective of whether the factors were included in regression models or not, early tweet counts had a weak positive and significant association with the later citations counts (3.3%) and the probability of a paper being cited (21.1%). Regarding gender, the findings showed that when all variables were controlled, female (first, last) authored papers had a small citation advantage of 3.7% and 4.2% in comparison to the male authored papers for the same number of tweets.

Use of author identifier services (ORCID, ResearcherID) and academic social networks (Academia.edu, ResearchGate) by the researchers of the University of Caen Normandy (France): A case study

The purpose of this paper was to assess the presence of researchers on two author identifier services (ORCID and ResearcherID) and to compare the results with two academic social networks (Academia.edu and ResearchGate) using the categories of discipline, career advancement, and gender in a medium sized multidisciplinary university in France (University of Caen Normandy). Metrics such as number of publications per researcher, h-indexes, and average number of citations were also assessed. Of the 1,047 researchers studied, 673 (64.3%) had at least one profile on the four sites, and the number of researchers having multiple profiles decreased as more sites were studied. Researchers with only one profile numbered 385 (36.8%), while 204 (19.5%) had two, 68 (6.5%) had three, and only 16 (1.5%) had four. ResearchGate had by far the highest number of researchers present, with 569 (54.3%), whereas presence on the other sites was about 15%. We found that, apart from Academia.edu, researchers in Sciences, Technology, and Medicine (STM) were over-represented. Overall, experienced male researchers were over-represented on the sites studied. Our results show that, because of the numerous profiles lacking publication references (particularly on ORCID) and a low presence of researchers on the four sites studied (except for ResearchGate), assessing the number of publications, h-indexes, or average number of citations per article of individuals or institutions remains challenging. Finally, our data showed that French researchers have not adopted the use of the two author identifier sites (i.e. ORCID and ResearcherID). As long as French researchers remain reticent, these sites will not be able to provide the services for which they were created: addressing the problem of author misidentification, consequently providing exhaustive access to scientific production and bibliometric indicators of individual researchers and their institutions.

Mobile phones: The effect of its presence on learning and memory

Our aim was to examine the effect of a smartphone's presence on learning and memory among undergraduates. A total of 119 undergraduates completed a memory task and the Smartphone Addiction Scale (SAS). As predicted, those without smartphones had higher recall accuracy compared to those with smartphones. Results showed a significant negative relationship between phone conscious thought, "how often did you think about your phone", and memory recall but not for SAS and memory recall. Phone conscious thought significantly predicted memory accuracy. We found that the presence of a smartphone and high phone conscious thought affects one's memory learning and recall, indicating the negative effect of a smartphone proximity to our learning and memory.

“People are reading your work,” scholarly identity and social networking sites

Purpose

Scholarly identity refers to endeavors by scholars to promote their reputation, work and networks using online platforms such as ResearchGate, Academia.edu and Twitter. This exploratory research investigates benefits and drawbacks of scholarly identity efforts and avenues for potential library support.

Design/methodology/approach

Data from 30 semi-structured phone interviews with faculty, doctoral students and academic librarians were qualitatively analyzed using the constant comparisons method (Charmaz, 2014) and Goffman’s (1959, 1967) theoretical concept of impression management.

Findings

Results reveal that use of online platforms enables academics to connect with others and disseminate their research. scholarly identity platforms have benefits, opportunities and offer possibilities for developing academic library support. They are also fraught with drawbacks/concerns, especially related to confusion, for-profit models and reputational risk.

Research limitations/implications

This exploratory study involves analysis of a small number of interviews (30) with self-selected social scientists from one discipline (communication) and librarians. It lacks gender, race/ethnicity and geographical diversity and focuses exclusively on individuals who use social networking sites for their scholarly identity practices.

Social implications

Results highlight benefits and risks of scholarly identity work and the potential for adopting practices that consider ethical dilemmas inherent in maintaining an online social media presence. They suggest continuing to develop library support that provides strategic guidance and information on legal responsibilities regarding copyright.

Originality/value

This research aims to understand the benefits and drawbacks of Scholarly Identity platforms and explore what support academic libraries might offer. It is among the first to investigate these topics comparing perspectives of faculty, doctoral students and librarians.

Unveiling knowledge quality, researcher satisfaction, learning, and loyalty

Purpose

Examines how perceived knowledge quality influences researchers' satisfaction with academic social media (ASM) site use, perceived learning from use, and loyalty toward the site.

Design/methodology/approach

Built upon the theoretical grounding of the information system success framework, it was hypothesized that satisfaction, perceived learning, and loyal behavior toward an ASM site are all functions of the perceived quality of knowledge obtained. Data were collected by online survey from 348 researchers registered on ResearchGate and subjected to SmartPLS structural equation modeling, bootstrapping, and blindfolding.

Findings

The hypothesized relationships were supported. Perceived knowledge quality significantly influences researchers' satisfaction with ASM site use, and satisfaction affects perceived learning and researchers' loyalty with the ASM site.

Research limitations/implications

Identification of the relationship between perceived knowledge quality and ASM site success extends the study of ASM sites from description of usage patterns to understanding the effect of content quality on important outcomes of use.

Practical implications

ASM sites rely on the quality of knowledge contributed by their members for satisfaction, loyalty, and perceptions of value. The ongoing success of an ASM requires directed attention to quality knowledge provision.

Originality/value

This paper contributes a simplified DeLone & McLean information system success framework for studies of content quality. It also provides fresh insights into ASM site usage through a focus on the role of perceived knowledge quality in forming satisfaction, learning, and loyalty.

Identifying author heritage using surname data: An application for Russian surnames

This research article puts forward a method to identify the national heritage of authors based on the morphology of their surnames. Most studies in the field use variants of dictionary‐based surname methods to identify ethnic communities, an approach that suffers from methodological limitations. Using the public file of ORCID (Open Researcher and Contributor ID) identifiers in 2015, we developed a surname‐based identification method and applied it to infer Russian heritage from suffix‐based morphological regularities. The method was developed conceptually and tested in an undersampled control set. Identification based on surname morphology was then complemented by using first‐name data to eliminate false‐positive results. The method achieved 98% precision and 94% recall rates—superior to most other methods that use name data. The procedure can be adapted to identify the heritage of a variety of national groups with morphologically regular naming traditions. We elaborate on how the method can be employed to overcome long‐standing limitations of using name data in bibliometric datasets. This identification method can contribute to advancing research in scientific mobility and migration, patenting by certain groups, publishing and collaboration, transnational and scientific diaspora links, and the effects of diversity on the innovative performance of organizations, regions, and countries.

Presencia, actividad, visibilidad e interdisciplinariedad del profesorado universitario de Documentación en los medios sociales: una perspectiva de género

Se estudia la presencia, actividad, visibilidad e interdisciplinaridad de 349 profesoras y profesores de Documentación en los medios sociales, para comprobar si existen diferencias entre los dos conjuntos. Las plataformas estudiadas incluyen ResearchGate (RG), Google Scholar Citations (GSC), y Twitter, y la población analizada corresponde al profesorado de 13 universidades españolas que ofertan formación en Biblioteconomía y Documentación. Los datos se recogieron entre abril y junio de 2018. Para las cuatro dimensiones de estudio se analizaron diferentes variables, incluyendo, entre otros, el número de documentos subidos a RG y el número de tweets, respuestas y retweets en Twitter para la actividad, y el porcentaje de documentos en acceso abierto y de documentos diferentes a los géneros tradicionales en RG y el número de seguidores y seguidoras por perfil en Twitter para la visibilidad. Los resultados apuntan a diferencias entre los dos colectivos, especialmente acentuadas en términos de visibilidad.

Which Are the Tools Available for Scholars? A Review of Assisting Software for Authors during Peer Reviewing Process

There is a large amount of Information Technology and Communication (ITC) tools that surround scholar activity. The prominent place of the peer-review process upon publication has promoted a crowded market of technological tools in several formats. Despite this abundance, many tools are unexploited or underused because they are not known by the academic community. In this study, we explored the availability and characteristics of the assisting tools for the peer-reviewing process. The aim was to provide a more comprehensive understanding of the tools available at this time, and to hint at new trends for further developments. The result of an examination of literature assisted the creation of a novel taxonomy of types of software available in the market. This new classification is divided into nine categories as follows: (I) Identification and social media, (II) Academic search engines, (III) Journal-abstract matchmakers, (IV) Collaborative text editors, (V) Data visualization and analysis tools, (VI) Reference management, (VII) Proofreading and plagiarism detection, (VIII) Data archiving, and (IX) Scientometrics and Altmetrics. Considering these categories and their defining traits, a curated list of 220 software tools was completed using a crowdfunded database (AlternativeTo) to identify relevant programs and ongoing trends and perspectives of tools developed and used by scholars.

The academic web profile as a genre of “self-making”

Purpose

The activities of academic researchers are increasingly regulated by neo-liberal ideals, including expectations that researchers are visible online and actively promote their output. The purpose of this paper is to explore how researchers take on this responsibility. It uses the concepts of genre, authorship and self-writing in order to understand how the story of an academic life is constructed on academic web profiles.

Design/methodology/approach

A qualitative content analysis was conducted of material on 64 profiles belonging to 20 researchers on institutional and personal websites, as well as on ResearchGate, Academica.edu and Google Scholar.

Findings

The study shows that while institutional websites primarily contain researcher-produced material, content on commercial platforms is often co-constructed through distributed authorship by the researcher, the platform and other platform users. Nine different ways in which the profile of an “academic self” may be said to highlight the particular strengths of a researcher are identified. These include both metrics-based strengths and qualitative forms of information about the academic life, such as experience, the importance of their research and good teaching.

Social implications

This study of academic web profiles contributes to a better understanding of how researchers self-govern the story of their academic self, or resist such governance, in online environments.

Originality/value

The study furthers the knowledge of how researchers make use of and respond to digital tools for online visibility opportunities and how the story of the “academic self” is “made” for such public presentation.

Awareness and use of self-archiving options among academic librarians in Nigerian universities

Purpose

The purpose of this study was to investigate the extent to which academic librarians in Nigerian universities use self-archiving options to make their research papers visible globally.

Design/methodology/approach

An online survey was designed using SurveyMonkey software to collect data from 394 academic librarians in Nigerian Universities.

Findings

The study revealed that the academic librarians in Nigerian universities know and actually use self-archiving options such as ResearchGate, institutional repository and Academia.edu to self-archive their publications. While other promotional tools such as kudos, Mendeley.com and personal websites/servers are not popularly used by the academic librarians. Increased exposure of previously published work, broadens the dissemination of academic research generally, and increases institutions’ visibility were among the factors the academic librarians indicated as very important that motivate them to contribute their scholarly output to self-archiving options.

Research limitations/implications

One major challenge to the study is that many academic librarians in Nigeria do not check their e-mails regularly to enable them to respond to a request to participate in an online survey; some of them do not have stable internet facilities, whereas others are reluctant to respond to an online questionnaire. These reasons led to a low response rate which makes it difficult to generalize findings.

Practical implications

Findings from the study will create awareness for academic librarians in developing countries to see the need to self-archive their pre-print and accepted version of their papers in different self-archiving platforms.

Originality/value

Self-archiving of papers by authors will lead to an increased visibility of the author and possible citation of the work and chances of collaboration with international colleagues for research projects.

Exploring the utility of Academia.edu: a SWOT analysis

Purpose

This paper aims to analyze the strengths, weaknesses, opportunities and threats of the academic social networking, Academia.edu.

Design/methodology/approach

SWOT analysis is performed to evaluate the platform.

Findings

Academia.edu provides resources that enable scholars to heighten the impact and reach of their research within a digitally networked environment.

Originality/value

This is one of the first studies to evaluate the scholarly merits of Academia.edu.

Users' Distribution and Behavior in Academic Social Networking Sites

Academic social networking sites (SNSs) are growing rapidly. Worldwide, academicians use academic SNSs for many reasons regardless of their nation, gender, position, and discipline. In this paper, the authors extend their previous work in exploring the distribution and behavior of a particular academic SNS (academia.edu) on a large scale. The authors classify users into different groups based on their position, discipline, and continent. This study gives a better understanding of usage patterns in academic SNS, especially in the lack of large-scale studies about different classes of users on academic SNSs.

Researchers’ attitudes towards the use of social networking sites

Purpose

The purpose of this paper is to better understand why many researchers do not have a profile on social networking sites (SNS), and whether this is the result of conscious decisions.

Design/methodology/approach

Thematic analysis was conducted on a large qualitative data set from researchers across three levels of seniority, four countries and four disciplines to explore their attitudes toward and experiences with SNS.

Findings

The study found much greater scepticism toward adopting SNS than previously reported. Reasons behind researchers’ scepticism range from SNS being unimportant for their work to not belonging to their culture or habits. Some even felt that a profile presented people negatively and might harm their career. These concerns were mostly expressed by junior and midlevel researchers, showing that the largest opponents to SNS may unexpectedly be younger researchers.

Research limitations/implications

A limitation of this study was that the authors did not conduct the interviews, and therefore reframing or adding questions to specifically unpack comments related to attitudes, feelings or the use of SNS in academia was not possible.

Originality/value

By studying implicit attitudes and experiences, this study shows that instead of being ignorant of SNS profiles, some researchers actively opt for a non-use of profiles on SNS.

Usage of academic social networking sites by Karachi social science faculty

The last decade has seen the emergence of academic social networking sites as a vehicle for scholars to promote their research and communicate with other scholars in their field. Given the small number of studies on the use of such sites by Pakistani academics, the authors conducted an exploratory study of social science faculty members at five Karachi (Pakistan) public sector universities. Analysis of the 68 valid responses revealed that the primary reason for accessing an academic social networking site was to search for articles on the site. Results also showed that accruing citations was the main reason for which respondents uploaded their own publications. The findings validate a role for librarians to support academics in their creation of effective online academic profiles.

Academic researchers’ behavioural intention to use academic social networking sites: A case of Malaysian research universities

This study seeks to validate a comprehensive model of academic researchers’ intention in the context of academic social networking sites (ASNSs). It uses the Unified Theory of Acceptance and Use of Technology (UTAUT) model with constructs of perceived security, perceived privacy, trust, attitude towards technology, and communication benefits as well as age, gender and experience as moderator variables. The survey results supported the positive relationships between the factors in the model, except effort expectancy, which had no significant effect on behavioural intention. However, the results of three moderator variables demonstrated that they had no significant effect on the adoption of ASNSs. The finding of this research will provide directions for ASNSs providers to support them in developing effective ASNSs for academic researchers.

The lost academic home: institutional affiliation links in Google Scholar Citations

Purpose

Google Scholar Citations (GSC) provides an institutional affiliation link which groups together authors who belong to the same institution. The purpose of this paper is to ascertain whether this feature is able to identify and normalize all the institutions entered by the authors, and whether it is able to assign all researchers to their own institution correctly.

Design/methodology/approach

Systematic queries to GSC’s internal search box were performed under two different forms (institution name and institutional e-mail web domain) in September 2015. The whole Spanish academic system (82 institutions) was used as a test. Additionally, specific searches to companies (Google) and world-class universities were performed to identify and classify potential errors in the functioning of the feature.

Findings

Although the affiliation tool works well for most institutions, it is unable to detect all existing institutions in the database, and it is not always able to create a unique standardized entry for each institution. Additionally, it also fails to group all the authors who belong to the same institution. A wide variety of errors have been identified and classified.

Research limitations/implications

Even though the analyzed sample is good enough to empirically answer the research questions initially proposed, a more comprehensive study should be performed to calibrate the real volume of the errors.

Practical implications

The discovered affiliation link errors prevent institutions from being able to access the profiles of all their respective authors using the institutions lists offered by GSC. Additionally, it introduces a shortcoming in the navigation features of Google Scholar which may impair web user experience.

Social implications

Some institutions (mainly universities) are under-represented in the affiliation feature provided by GSC. This fact might jeopardize the visibility of institutions as well as the use of this feature in bibliometric or webometric analyses.

Originality/value

This work proves inconsistencies in the affiliation feature provided by GSC. A whole national university system is systematically analyzed and several queries have been used to reveal errors in its functioning. The completeness of the errors identified and the empirical data examined are the most exhaustive to date regarding this topic. Finally, some recommendations about how to correctly fill in the affiliation data (both for authors and institutions) and how to improve this feature are provided as well.

Toward a homogenization of academic social sites

Purpose

The purpose of this paper is to analyze the distribution of profiles from academic social networking sites according to disciplines, academic statuses and gender, and detect possible biases with regard to the real staff distribution. In this way, it intends to know whether these academic places tend to become specialized sites or, on the contrary, there is a homogenization process.

Design/methodology/approach

To this purpose, the evolution of profiles of one organization (Consejo Superior de Investigaciones Científicas) in three major academic social sites (Academia.edu, Google Scholar Citations and ResearchGate) through six quarterly samples since April 2014 to September 2015 are tracked.

Findings

Longitudinal results show important disciplinary biases but with strong increase of new profiles form different areas. They also suggest that these virtual spaces are gaining more stability and they tend toward a equilibrate environment.

Originality/value

This is the first longitudinal study of profiles from three major academic social networking sites and it allows to shed light on the future of these platforms’ populations.
