Academic social networks – the Swiss Army Knives of scholarly communication

This post was originally published on this site


On December 7, 2016, at the STM Innovations Seminar  we gave a presentation (available from Figshare) on academic social networks. For this, we looked at the functionalities and usage of three of the major networks (ResearchGate, Mendeley and Academia.edu) and also offered some thoughts on the values and choices at play both in offering and using such platforms.

Functionalities of academic social networks
Academic social networks support activities across the research cycle, from getting job suggestions, sharing and reading full-text papers to following use of your research output within the system. We looked at detailed functionalities offered by ResearchGate, Mendeley and Academia.edu (Appendix 1) and mapped these against seven phases of the research workflow (Figure 1).

In total, we identified 170 functionalities, of which 17 were shared by all three platforms. The largest overlap between ResearchGate and Academia lies in functionalities for discovery and publication (a.o. sharing of papers), while for outreach and assessment, these two platforms have many functionalities that do not overlap. Some examples of unique functionalities include publication sessions (time-limited feedback sessions on one of your full text papers) and making metrics public or private in Academia, and Q&A’s, ‘enhanced’ full-text views and downloads and the possibility to add additional resources to publications in ResearchGate. Mendeley is the only platform offering  reference management and specific functionality for data storage, according to FAIR principles. A detailed list of all functionalities identified can be found in Appendix 1.

Within the seven phases of the research cycle depicted above, we identified 31 core research activities. If the functionalities of ResearchGate, Mendeley and Academia are mapped against these 31 activities (Figure 2), it becomes apparent that Mendeley offers the most complete support of discovery, which ResearchGate supports archiving/sharing of the widest spectrum of research output. All three platforms support outreach and assessment activities, including impact metrics.

What’s missing?
Despite offering 170 distinct functionalities between them, there are still important functionalities that are missing from the three major academic social networks. For a large part, these center around integration with other platforms and services:

  • Connect to ORCID  (only in Mendeley), import from ORCID
  • Show third party altmetrics
  • Export your publication list (only in Mendeley)
  • Automatically show and use clickable DOIs (only in Mendeley)
  • Automatically link to research output/object versions at initial publication platforms (only in Mendeley)

In addition, some research activities are underserved by the three major platforms. Most notably among these are activities in the analysis phase, where functionality to share notebooks and protocols might be a useful addition, as would text mining of full-text publications on the platform. And while Mendeley offers extensive reference management options, support for collaborative writing is currently not available on any of the three platforms.

If you build it, will they come?
Providers of academic social networks clearly aim to offer researchers a broad range of functionalities to support their research workflow. But which of these functionalities are used by which researchers? For that, we looked at the data of 15K researchers from our recent survey on scholarly communication tool usage. Firstly, looking at the question on which researcher profiles people use (Figure 3), it is apparent that of the preselected options, ResearchGate is the most popular. This is despite the factor that overall Academia.edu report a much higher number of accounts (46M compared to 11M for ResearchGate). One possible explanation for this discrepancy could be a high number of lapsed or passive accounts on Academia.edu – possibly set up by students.

Looking  a bit more closely at the use of ResearchGate and Academia in different disciplines (Figure 4), ResearchGate proves to be dominant in the ‘hard’ sciences, while Academia is more popular in Arts & Humanities and to a lesser extent in Social Sciences and Economics. Whether this is due to the specific functionalities the platforms offer, the effect of what one’s peers are using or even to the name of the platforms (with researchers from disciplines identifying more with the term ‘Research’ than ‘Academia’ or vice versa) is up for debate.

If they come, what do they do?
Our survey results also give some indication as to what researchers are using academic social networks for. We had ResearchGate and Mendeley as preset answer options in a number of questions about different research activities, allowing a quantitative comparison of the use of these platforms for these specific activities (Figure 5). These results show that of these activities, ResearchGate is most often used as researcher profile, followed by its use for getting access to publications and sharing publications, respectively. Mendeley was included as preset answer option for different activities; of these, it is most often used for research management, following by reading/viewing/annotating and searching for literature/data. The results also show that for each activity it was presented as a preset option for, ResearchGate is used by most often by postdocs, while Mendeley is predominantly used by PhD students. Please note that these results do not allow a direct comparison between ResearchGate and Mendeley, except for the fourth activity in both charts: getting alerts/recommendations.

In addition to choosing tools/platforms presented as preset options, survey respondents could also indicate any other tools they use for a specific activity. This allows us to check for which other activities people use any of the academic social networks, and plot these against the activities these platforms offer functionalities for. The results are shown in Figure 6 and indicate that, in addition to activities supported by the respective platforms, people also carry out activities on social networks for which there are no dedicated functionalities. Some examples are using Academia and ResearchGate for reference management, and sharing all kinds of research outputs, including formats not specifically supported by  the respective networks. Some people even indicate using Mendeley for analysis – we would love to find out what type of research they are carrying out!

For much more and alternative data on use of these platforms’ functionalities please read the analyses by Ortega (2016), based on scraping millions of pages in these systems.

Good, open or efficient? Choices for platform builders and researchers
Academic social networks are built for and used by many researchers for many different activities. But what kind of scholarly communication do they support? At Force11, the Scholarly Communications Working Group (of which we both are steering committee members) has been working on formulating principles for scholarly communication that encourage open, equitable, sustainable, and research- and culture-led (as opposed to technology- and business-model led) scholarschip.

This requires, among other things, that research objects and all information about them can be freely shared among different platforms, and not be locked into any one platform. While Mendeley has an API  they claim is fully open,  both ResearchGate and Academia are essentially closed systems. For example, all metrics remain inside the system (though Academia offers an export to csv that we could not get working) and by uploading full text to ResearchGate you grant them the right to change your PDFs (e.g. by adding links to cited articles that are also in ResearchGate).

There are platforms that operate from a different perspective, allowing a more open flow of research objects. Some examples are the Open Science Framework, F1000 (with F1000 Workspace), ScienceOpen, Humanities Commons and GitHub (with some geared more towards specific disciplines). Not all platforms support all the same activities as ResearchGate and Academia (Figure 7), and there are marked differences in the level of support for activities: sharing a bit of code through ResearchGate is almost incomparable to the full range of options for this at GitHub. All these platforms pose alternatives for researchers wanting to conduct and share their research in a truly open manner.
