Nature Machine Intelligence will publish primary research in one format, Article, which can range in length from short communications to longer, more in-depth reports. Regardless of length, an Article should report an important research study of high quality and general interest to the broad machine intelligence community. The main text (excluding abstract, Methods section, references and figure legends) is typically limited to 3,500 words. Articles can have up to 6 display items (figures and/or tables) and as a guideline up to around 50 references (excluding those cited exclusively in Methods). Articles have an unreferenced abstract of approximately 150 words. The abstract should contain a brief account of the background and rationale of the work, followed by a statement of the main conclusions, and their implications, introduced by the phrase 'Here we show' or some equivalent. The main text of an Article should begin with an introduction (without heading) of referenced text that expands on the background of the work (some overlap with the abstract is acceptable), and is followed by a concise, focused account of the findings, typically ending with one or two short paragraphs of discussion. The main text may be divided by a few short topical headings of no more than 60 characters (including spaces). Articles can also contain a Methods section, which should appear after the main text and should typically not exceed 3,000 words.
Articles include received/accepted dates and may be accompanied by supplementary information. Articles are peer reviewed.
A Review is an authoritative, balanced survey of recent developments in a research field. Although Reviews should be recognized as scholarly by specialists in the field, they should be written with a view to informing non-specialist readers. Thus, Reviews should be presented using simple prose, avoiding excessive jargon and technical detail. Reviews are approximately 3,000–4,000 words long and typically include 4–6 display items (figures, tables or boxes). As a guideline, Reviews allow up to 100 references; citations should be selective. Footnotes are not used. The scope of a Review should be broad enough that it is not dominated by the work of a single research institution, and particularly not by the authors' own work.
Reviews include received/accepted dates. Reviews are always peer-reviewed to ensure factual accuracy, appropriate citations and scholarly balance.
A Perspective is intended to provide a forum for authors to discuss models and ideas from a personal viewpoint. They are more forward-looking and/or speculative than Reviews and may take a narrower field of view. They may be opinionated but should remain balanced and are intended to stimulate discussion and new experimental approaches. Perspectives follow the same formatting guidelines as Reviews. As with Reviews, many Perspectives are invited by the editors, so it is advisable to send a pre-submission enquiry including a synopsis before preparing a manuscript for formal submission.
Perspectives include received/accepted dates. Perspectives are always peer-reviewed and edited by the editors in consultation with the author.
News & Views
News & Views articles inform readers about the latest advances in artificial intelligence research, as reported in recently published papers (in Nature Machine Intelligence or elsewhere) or at scientific meetings. Unsolicited contributions will not normally be considered, although prospective authors are welcome to make proposals. News & Views are not peer reviewed, but undergo editing in consultation with the author.
The Correspondence section provides a forum for comment on papers or discussion of issues relevant to the journal’s community. A Correspondence should not exceed more than one printed page and is typically 250–500 words; it is limited to one display item and, as guideline, Correspondence allows up to 10 references. Article titles are omitted from the reference list. Titles for Correspondences are supplied by the editors. Correspondence may be peer-reviewed at the editors’ discretion. Note that Correspondence pieces are not technical comments on peer-reviewed research papers which would be considered Matters Arising.
Matters Arising are exceptionally interesting and timely scientific comments and clarifications on original research papers published in Nature Machine Intelligence. These comments should ideally be based on knowledge contemporaneous with the original paper, rather than subsequent scientific developments.
For detailed information on how to submit a Matters Arising, please follow instructions here.
Comment articles can focus on policy, science and society or purely scientific issues related to artificial intelligence and robotics. Single-author articles are preferred as this is an 'opinion' section of the journal. Comments are usually commissioned by the editors, but proposals are welcome. They should be of immediate interest to a broad readership and should be written in an accessible, non-technical style. Figures and diagrams are encouraged, but are not a requirement. Comments are typically no longer than 1,500 words and, as a guideline, allow up to 15 references. Article titles are omitted from the reference list.
Comments may be peer-reviewed at the editors' discretion.
Books & Arts
The Books & Arts section comprises timely reviews of books and other cultural and pedagogical resources of interest to the artificial intelligence and robotics community. The pieces are limited to one page. They are usually commissioned, though unsolicited contributions will be considered.
Features and News Features
These sections are written or commissioned by the journal editors. They do not contain unsolicited material. We are, however, keen to accept freelance pitches of exclusive stories, particularly conference coverage from locations where we do not have staff, or reports from interesting field work.
All of our features are written with a lively, proactive tone, using language that is clear even to readers for whom English is not their native tongue. Stories should be accessible to those with a general interest and background in science.
