Scientific writing: the online cooperative

Collaborative browser-based tools aim to change the way researchers write and publish their papers.

When Fernando Cagua was preparing to write up his findings on the economics of whale-shark tourism, he didn't fire up Microsoft Word. He opened his web browser.

Cagua, an ecologist at King Abdullah University of Science and Technology in Thuwal, Saudi Arabia, was keen to try out an online writing environment that would allow him and his three co-authors to work on the same paper simultaneously. Over the past few years, a small cadre of tools have sprung up expressly for this purpose. Although the features vary, each is designed to ease a key difficulty in writing multi-authored research papers: handling collaboration. And some of the creators have wider ambitions — to fundamentally alter the way that scientific papers are written and published.

Writing a paper is traditionally a stepwise process. One author shares drafts with colleagues and then waits for everyone to reply or moves forward independently, folding in revisions and queries as they arrive. The more co-authors, the more complicated this gets, says Russell Neches, a microbiology PhD student at the University of California, Davis. “Managing that process can be more difficult, more time-consuming and more work than the research itself,” he says.

Collaborative tools simplify this process by allowing multiple authors to edit and format an online document at the same time. The most widely used general-purpose collaborative writing app is probably Google Docs — essentially a stripped-down, online version of Microsoft Word. But there are also more-technical tools designed specifically for researchers. These applications add options such as the ability to control a document's layout and to add citations in a way that suits scientific manuscripts. The tool that Cagua had his eye on, for instance, writeLaTeX, was so named because it uses the typesetting computer language LaTeX — popular among physical scientists and mathematicians for rendering mathematical formulas, tables and figures. (The tool is produced by a company also called writeLaTeX, supported by Digital Science, a division of Macmillan, which publishes Nature. In January, the firm relaunched the tool and renamed it Overleaf.) Other scholar-focused online writing apps include shareLaTeX, Fidus Writer andAuthorea.

Word of mouth

A minority of researchers use these apps, but their number is growing. In the past year, registered users of Overleaf have reached 100,000, says writeLaTeX co-founder John Hammersley, and they have created more than 1.4 million documents with the tool. Authorea has 10,000 users, according to its co-founder Alberto Pepe. Jenna Morgan Lang, a postdoc in the same group as Neches, says that she has one Authorea-written paper in preprint and six more in development. “I do love it,” she says, “and I tell everyone who will listen that they should be using it, too.”

At the heart of the collaborative approach is the way the tools keep track of different versions of the same document. Authorea, for example, breaks documents into user-defined, paragraph-sized chunks that only one author can edit at a time, but multiple researchers can work on different sections of a document simultaneously. The system records every change in a document history. “You can go back and understand how a scientific paper evolved from the first word to the last,” says Pepe.

For Authorea, that concept is based on the software-management system Git, used by programmers to keep track of changes on collaborative code-writing projects, and by data scientists to record their analysis workflow. Other tools take different approaches: Google Docs and Fidus Writer allow all users access to the entire file simultaneously, and track changes more or less like Microsoft Word, but Fidus Writer, for example, does not save a detailed, time-stamped version history. Overleaf allows both a version history and a track-changes facility — but the latter is available only to paying subscribers. Although each tool offers a free account, only researchers willing to pay monthly fees (US$7–12 for Overleaf and $5–25 for Authorea) can access the advanced features, such as more storage space or private accounts.

The tools are much more than just word processors and collaboration managers, however. Authorea allows users to build and format bibliographies by searching and importing references from PubMed or CrossRef, or using DOIs (digital object identifiers); Overleaf allows imports from reference managers Zotero and CiteULike. Authorea also enables users to export documents in any of about 40 different journal formats, including those of Nature, Science and Proceedings of the National Academy of Sciences. By recasting the same data through different journal filters, “it's a bit like Instagram for scientific papers”, Pepe wrote in one blogpost.

At writeLaTeX, Hammersley has ambitions to integrate the writing and publishing of articles even more closely. Users can click a button to transmit their article directly to journal editors; the company currently has arrangements with around a dozen journals, and many more will follow in the next few months, Hammersley says. However, Cagua says that he did not find the process particularly automatic with a paper he transmitted to PeerJ; he had to resubmit information in his original LaTeX file that was not automatically picked up by the journal. But Hammersley says that integration with journals is a work in progress. Ultimately, he hopes that a paper's author and its journal editor might collaborate on the article together in the browser window.

Familiar ground

Cagua also ended up writing most of his whale-shark paper in Google Docs, because his co-authors were not well versed in LaTeX and so found the original writeLaTeX “too intimidating”. A raw LaTeX file — text interspersed with code that tells typesetting programs how to display the prose and figures — can look off-putting to the uninitiated, or just ugly, like reading the HTML source code behind a web browser's display. In the relaunched version, Overleaf, a rich-text editing environment hides the code and makes writing friendlier for non-experts. Fidus Writer and Authorea also support LaTeX, as well as other computer languages for controlling the display of raw text, including HTML and Markdown.

Authorea's “fundamental mission”, Pepe says, “is to re-imagine the scientific article”. Conceived to advance the open sharing of scientific research, the program supports software such as IPython notebooks, which allow readers to explore and manipulate the data underlying published figures. “We believe in the idea of an interactive, data-driven article,” Pepe explains — an idea that he has explored in a prototype 'Paper of the future' (see go.nature.com/plgshx). A few journals are cautiously experimenting with interactive graphics and data in their articles, although for the most part, this is still rare.

An Authorea-written document can double as both a readable paper and an online research notebook containing raw data, notes Alyssa Goodman, an astronomer at Harvard University who was Pepe's postdoctoral adviser when he developed the software. “The part you can read that looks like a paper is the tip of the iceberg that describes everything underneath,” she explains.

Using that feature, Neches collaborated with two researchers in Michigan who he chatted with on Twitter but has never met in person. Together, they studied whether materials printed with a 3D printer were sterile for use in bacterial culture experiments. Authorea, he says, provided a forum for team members to upload raw data and methods, from which they could co-assemble a manuscript online. “It was very much as though we had created a laboratory in which we worked together,” he says. “It probably would not have happened at all without a tool like Authorea existing.”

科研写作在云端:协同写作工具

. ^2 e! `  n8 y; _' w( ]& D6 x目前我在法国的办公室写几篇研究论文,我的其他共同作者分别在巴西以及美国的2个城市,在大家身处异地的情况下,我该怎么和他们合作写科研论文呢?有好一段时间我们都是用word档案的追踪修订功能然后透过邮件来回编辑文稿,有过这个经验的人一定知道邮件同时不停来回发送有多混乱,更别说要怎么处理10个不同版本的论文了。现在随着云端计算服务的兴起,实时协同写作不再遥不可及。那些无穷尽的邮件还有跟上每一个版本的论文内容的疯狂情景再也不会发生!一些云端工具可以让我们轻松的在浏览器上协同编辑同一份稿件,所有的修改都能安全的储存在远端伺服器上。5 N+ I% ~$ M* M; x+ f
5 h: |* S1 {. G- f$ c$ P
云端写作工具如谷哥文档(Google docs),Sky-Drive和SciGit能够进行多人实时编辑,还提供进阶的控制元件,这些工具都是免费的,而各自有各自的优点。谷哥文档提供丰富的功能也能与谷哥的其他应用套件连接,SkyDrive的最大优点是与微软软件的兼容性,而SciGit则是以专业科研写作见长。有些人喜欢用LaTex写作,Latex对于使用复杂数学公式的写作特别有用,LaTex用户的网路协同写作平台则有ShareLaTeX、WriteLaTeX和Authorea。

5 }( q2 l/ j8 V9 X谷哥文档因为其附加功能,如免费方程式功能、词库、开放剪贴资源以及参考文献管理器等,目前成为传统文档工具的强烈竞争者。另一个对科研人员来说好用的工具还有Paperpile,它是在线参考文献管理工具,能在Chrome和谷哥应用程式上使用,帮助在线寻找、组织、阅读和写作,属于Chrome的应用程式,意味着Mac和一般计算机都能够在任何地方使用。用户可以构建搜集到的参考文献并从其他参考文献管理工具或在线阅读的论文导入成PDF链接。Paperpile与学术搜索引擎Pubmed和谷哥学术搜索的接口做得特别好,能够一键加入参考资料并下载PDF至谷哥Google drive存储。
