What is ResearchGate?
A Scholarly Network
ResearchGate, launched in May 2008, functions as a commercial social networking service specifically tailored for the global scientific and research community. Its primary objective is to facilitate the sharing of academic papers, foster intellectual discourse through questions and answers, and enable researchers to identify and connect with potential collaborators across various disciplines.
Recognized by studies in prominent journals such as Nature (2014) and Times Higher Education (2016), ResearchGate has established itself as the largest academic social network in terms of active users, distinguishing itself from other services that may boast higher numbers of registered but less engaged users.
Access & Interaction
While the platform allows public visitors to read articles without requiring registration, full membership is contingent upon possessing an email address from a recognized academic institution or undergoing a manual verification process as a published researcher. This gatekeeping mechanism aims to maintain the professional integrity of the network.
Members are empowered to upload a diverse range of research outputs, including peer-reviewed papers, raw data, book chapters, reports on negative results, patents, research proposals, methodologies, presentations, and even software source code. Beyond content sharing, the platform supports dynamic interaction, allowing users to follow the activities of other members, participate in discussions, and manage their network by blocking unwanted interactions.
Global Reach & Scope
ResearchGate serves a worldwide academic audience, with its headquarters located in Berlin, Germany. As of September 2023, the platform reported a substantial user base of 25 million, demonstrating its significant global footprint. While its largest concentrations of users are found in Europe and North America, the platform attracts researchers from a broad spectrum of scientific fields.
The user demographic predominantly comprises individuals engaged in medicine and biology. However, ResearchGate also actively supports professionals and scholars in diverse areas such as engineering, law, computer science, agricultural sciences, and psychology, fostering interdisciplinary connections and knowledge exchange.
Key Features
Core Functionalities
ResearchGate integrates various functionalities reminiscent of popular consumer social media platforms, often described as a "mashup" of Facebook, Twitter, and LinkedIn, but specifically adapted for academic purposes. Users can curate their experience by following specific research interests in addition to individual colleagues, thereby tailoring their content feed.
The platform includes a blogging feature, enabling users to compose concise reviews of peer-reviewed articles, fostering critical engagement with published literature. ResearchGate's intelligent indexing system leverages self-published information on user profiles to suggest relevant connections, enhancing networking opportunities. Furthermore, a unique question-and-answer mechanism directs user queries to members who have self-identified relevant expertise, facilitating targeted problem-solving and knowledge dissemination. For sensitive collaborations, private chat rooms are available, supporting data sharing, collaborative document editing, and confidential discussions.
Career & Metrics
Beyond scholarly exchange, ResearchGate provides practical career resources, including a dedicated research-focused job board. This feature assists academics in identifying new opportunities within their fields.
Historically, ResearchGate introduced an "RG Score" in 2012, an author-level metric intended to quantify scientific reputation. However, this proprietary algorithm faced significant criticism for its lack of transparency and reproducibility, with studies highlighting its questionable reliability and a strong correlation with journal impact factors rather than genuine scientific influence. Consequently, ResearchGate announced the discontinuation of the RG Score in March 2022, effective July 2022. It is important to note that ResearchGate does not impose fees for content uploads nor does it require peer review for uploaded materials, distinguishing its content model from traditional academic publishing.
History
Founding & Evolution
ResearchGate was co-founded in May 2008 by virologist Ijad Madisch, who continues to serve as the company's CEO, alongside physician Sรถren Hofmayer and computer scientist Horst Fickenscher. The venture initially commenced operations in Boston, Massachusetts, before relocating its headquarters to Berlin, Germany, shortly thereafter.
The platform's early development was highly iterative, with features being introduced and refined based on direct feedback from its scientific user base. This user-centric approach contributed to its rapid expansion, with the number of registered users surging from 25,000 in 2009 to over 1 million by 2011.
Funding Milestones
ResearchGate has attracted significant investment from prominent venture capital firms and influential figures in technology and philanthropy. Its initial funding round in 2010 was spearheaded by Benchmark, a leading venture capital firm, which also saw Benchmark partner Matt Cohler join ResearchGate's board of directors.
Subsequent funding rounds included a significant investment from Peter Thiel's Founders Fund in February 2012. A Series C financing round in June 2013 secured $35 million from investors, notably including Bill Gates. Further substantial funding of $52.6 million was acquired in November 2015 from a consortium of investors, including Goldman Sachs, Benchmark Capital, the Wellcome Trust, and Bill Gates, though this was publicly announced in February 2017.
Growth & Strategy
The company experienced substantial organizational growth, expanding from 12 employees in 2011 to 120 by 2014, and further to approximately 300 employees by 2016, including a dedicated sales team of 100. ResearchGate operates within a competitive landscape, contending with other academic platforms such as Academia.edu, Google Scholar, Mendeley, and more recently, Semantic Scholar.
Despite reported losses, which increased from โฌ5.4 million in 2014 to โฌ6.2 million in 2015, the CEO expressed optimism regarding the company's long-term financial viability. ResearchGate's business strategy is centered on highly targeted advertising, leveraging detailed analysis of user activities to present relevant products and services. This approach is based on the premise of tapping into the substantial global spending on scientific equipment and resources, estimated at $1 trillion annually.
Reception
Early Acclaim
In its nascent years, ResearchGate garnered positive attention for its potential to democratize scientific collaboration. A 2009 article in BusinessWeek lauded the platform as a "potentially powerful link" for fostering innovation, particularly by connecting scientists in developing nations with their counterparts in industrialized countries. The article highlighted the platform's user-friendly interface as a key factor in its popularity and noted its role in facilitating several significant cross-country scientific collaborations that led to substantive advancements.
Academic Perspectives
Academic reception of ResearchGate has generally remained positive, with reviews of existing literature indicating an accepting audience and broad conceptual coverage. A 2012 survey conducted at the University of Delhi found ResearchGate to be among the most popular social networking sites for academic purposes, alongside Facebook, although a majority of respondents also expressed concerns about social networking sites being a "waste of time."
A 2014 study by Nature revealed that 88% of surveyed scientists and engineers were aware of ResearchGate, with half visiting it regularly (second only to Google Scholar). However, less than 10% actively used it for research discussions, with 40% preferring Twitter for such interactions. A 2016 global survey reported in Times Higher Education further solidified ResearchGate's position as the dominant academic network, being twice as popular as its competitors, with 61% of published authors maintaining a profile. Despite this, some studies suggest that many academics primarily utilize ResearchGate as an "online CV" rather than for active question-and-answer engagement.
Impact on Access
The widespread adoption and usage of ResearchGate have had a notable impact on the perceived value of traditional academic publishing models. In the context of "big deal" cancellations by various library systems globally, ResearchGate's extensive availability of research papers has been cited as a factor that diminished the apparent value of subscriptions to toll-access resources.
Tools like Unpaywall Journals, which libraries employ to assess the true costs and benefits of their subscription options, now differentiate between content available on ResearchGate and that found in more stable open archives, such as institutional repositories. This distinction underscores ResearchGate's role in the evolving landscape of scholarly information access.
Critique
Ethical & User Concerns
ResearchGate has faced significant criticism regarding its ethical practices and user experience. A notable controversy arose from its refusal to remove convicted sex offenders, such as Benjamin Levin, from the platform, leading many researchers worldwide to delete their accounts in protest. Levin, identified as "Research Ben," had published numerous papers on child pornography and pedophilia on the site.
The platform was also criticized for sending unsolicited email invitations to coauthors of its users. These emails were designed to appear as if personally sent by the user, but were automatically generated unless the user explicitly opted out. This practice led to boycotts and contributed to a negative perception of ResearchGate within the scientific community, though the site reportedly discontinued this practice as of November 2016. Allegations of scraping competitors' websites for email addresses to send spam were also made, though denied by the CEO.
RG Score Controversy
The "RG Score," a proprietary author-level metric introduced by ResearchGate, became a focal point of criticism. Studies investigating its methodology concluded that the RG Score was "intransparent and irreproducible." Researchers found that the score could achieve high values under questionable circumstances and was heavily influenced by the journal impact factor, rather than reflecting genuine scientific impact or network centrality. Indeed, it was found to be negatively correlated with network centrality, meaning highly active users often did not have high RG Scores. While showing a strong positive correlation with institutional university rankings (like Quacquarelli Symonds), its correlation with individual author rankings (like Elsevier SciVal) was weak. Experts suggested that the RG Score should not be considered in the evaluation of academics due to these methodological flaws.
Content & Profile Integrity
Further criticism stemmed from ResearchGate's practice of automatically generating "apparent profiles" for non-users by scraping details such as affiliations, publication records, and available PDFs from across the web. This practice often misrepresented individuals who did not wish to be on the site, and ResearchGate reportedly refused to remove these pages upon request. The platform's use of a crawler to find and embed PDF versions of articles, presenting them as if uploaded by the author (with only an "External Download" button indicating otherwise), also raised concerns.
ResearchGate has also been criticized for its perceived leniency towards "the dark side of academic writing," including phenomena like fake publishers, "ghost journals," and predatory publication fees, which could undermine the integrity of scholarly communication. Moreover, the platform faced significant accusations of copyright infringement related to published works.
Legal & Partnerships
Copyright Disputes
The issue of copyright infringement escalated significantly in September 2017 when lawyers representing the International Association of Scientific, Technical, and Medical Publishers (STM) sent a letter to ResearchGate. This letter threatened legal action and demanded fundamental changes to ResearchGate's handling of uploaded articles. Specifically, it called for the implementation of pre-release checks for copyright violations, an end to the extraction and modification of content and metadata from hosted articles, and a cessation of ResearchGate's practice of copying and downloading published journal article content to create internal databases.
This was followed by an announcement that takedown requests would be issued for millions of articles deemed to be in copyright violation. A coalition of major publishers, including the American Chemical Society, Brill Publishers, Elsevier, Wiley, and Wolters Kluwer, formed the "Coalition for Responsible Sharing" (CfRS) to support these actions. CfRS later reported that ResearchGate had removed a "significant number" of copyrighted articles but noted that "not all violations have been addressed," leading to continued issuance of takedown notices.
Resolutions & Collaborations
Despite the legal challenges, ResearchGate has made strides in establishing agreements with some major publishers. In September 2023, ResearchGate, Elsevier, and the American Chemical Society announced a settlement to their litigation, indicating a move towards a solution that supports researchers while addressing copyright concerns.
Furthermore, ResearchGate has successfully forged agreements with other prominent publishers, including Springer Nature, Cambridge University Press, and Thieme. Under these agreements, publishers are to be notified when their articles are uploaded to the platform, although these agreements do not grant publishers the ability to pre-moderate uploads. In a move to expand its open access initiatives, ResearchGate partnered with Sage Publishing in January 2023 to facilitate the distribution of open access content, signaling a commitment to broader accessibility of scholarly work.
