Original unpublished theoretical papers dealing with the above stated problem areas.

Checked Open Submissions Checked Indexed Checked Peer Reviewed


Papers containing innovative applications of the above mentioned problem areas in science, medicine, economy or technology.

In order to make these applications easily understood and reproduced, the scientific journal Neural Network World must insist on the published papers being supported by complete sets of input data as well as source codes related to the applications (a model, a simulation, etc.) There must be a thorough documentation of the data and the code available to enable the possibility of further replication of the results. In case the authors are for some justifiable reason unable to provide either the data or the code or both, this must be clearly stated at the beginning of the submission process. Otherwise, all relevant information has to be made accessible together with a clear description of how it can be obtained. It is solely the authors who are fully responsible for distributing these materials. Consequently, it is the right of the editors not to accept a manuscript for publication if provision of the data and/or the code and/or the details to access these has been considered insufficient.

Peer Review Process

All submited manuscripts are first subject to pre-review by a selected member of the Editorial board. The pre-review decided whether the paper is within the scope of the NNW Journal and whether it is likely to pass the scrutiny of the peer-review process.

A manuscript accepted for peer-review will undergo a review by at least two independent reviewers. A member of the editorial staff then starts to address potential reviewers from our reviewer database, and waits for their accepting or declining the review. A typical review then takes up to 4 weeks counted from the moment the reviewer accepts a review. Depending on the quality and topic of the paper, a typical review round may take from less than 3 months to more than a year.

[TODO: Outline the journal's peer review policy and processes for readers and authors, including the number of reviewers typically used in reviewing a submission, the criteria by which reviewers are asked to judge submissions, typical time taken to conduct the reviews, and the principles for recruiting reviewers.]



Publication Frequency

The Neural Network World is a bimonthly journal. Currently we do not electronically publish the papers as soon as they are ready, but we collect them for the next issue. The electronic versions of printed papers are available approximately at the same time as the given issue is being printed.


Open Access Policy

This journal provides immediate open access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge.


FAQ: Frequently Asked Questions

Registering and Manuscript Submission

Q: I have registered but I still cannot log in. The error message says something about validating my account first.
A: All new accounts have to be validated before our users are allowed to log in. The validation process consists of sending an e-mail containing a URL link with a unique ID pointing back to our OJS. As soon as you visit the link, we are sure that your e-mail address really works and that our e-mails will be received. At that moment is your account validated and you may log in. Note that in certain cases the validation e-mail may be considered as spam by your e-mail gateway. In general, if you do not receive the validation message within 24 hours after registering, contact the technical support to manually enable your account.

Q: How shall I submit my manuscript after login?
A: The typical dashboard (login screen) of our user looks as follows:

If you do not see the Author line, it is likely that you have not registered as such (people often forget to tick the appropriate box when registering). If you want to submit a new manuscript, go to the [New Submission] link. This will start the five-step submission process.

Submission Processing

Q: How long will the pre-review of my submission take?
A: All manuscripts are first screened by selected members of the IEB and this process may take some time. However, it should not take more than four weeks before the Editor-in-chief decides that the submission is unsuitable for the journal (out-of-scope, poor quality, etc.) or assigns an editor (the status of the submission changes from UNASSIGNED to IN REVIEW).

Q: How long does the reviewing process take?
A: This depends very much on the topic and quality of the submission. The Section Editor, assigned to your paper, starts to address potential reviewers as soon as the manuscript has been assigned. A reviewer has generally 5 days for accepting the review task, after that another reviewer is selected. After accepting the review, reviewers are given 4 weeks to deliver their judgment. It may take up to 20-30 review requests (i.e. 150 days) before some reviewer accepts the review, and we do not always get the promised review back in time (sometimes we even have to look for another reviewer after the review has not been delivered).

Q: How much time does it take to typseset my paper after it has been accepted by reviewers?
A: The main decisive factors are (i) the submission format (MS Word requires a mostly manual and time-consuming conversion to LaTeX), (ii) the quality of initial typesetting (most authors tend to typeset mathematics incorrectly), (iii) the need to re-format and re-index the list of references, (iv) the quality of images (see the separate FAQ topic), and finally (v) the linquistic quality of the paper. In the present time, accepted papers have to wait for cca 3-5 months in a queue before we start the layout editing phase. The layout editing may take 1 day, but we have papers that need numerous iterations (and several weeks of work) before we may consider them acceptable for publication.

Q: How long will it take before my paper is published?
A: This is generally a sum of periods mentioned above. The time ranges from cca 6 months (LaTeX formatted and good quality papers, fast review, only minor revisions required) to more than 3 years (this is usually due to long reviewing process and submissions that require more reviewing rounds)

Reviewing process

Q: How can I access the reviews?
A: Unfortunately, the current version of our Electronic Submission System does not provide direct access to reviews from your dashboard. They will be e-mailed to you by the Editor, except for extra files, which are stored within OJS. Those files can be accessed from the manuscript dashboard only. You will find them in Peer Review block under Uploaded file. See the image below the next answer.

Q: Where do I upload the revised manuscript?
A: You can do so from the REVIEW tab of your submission. Just upload a new Author version in the Editor Decision block as indicated below:

Layout Editing

Q: Why is the quality of my EPS/PDF files not acceptable?
A: Main problem with EPS/PDF files submitted by many authors is that they provide us with colour or greyscale images that have been exported from MS Word and then converted to EPS. These images have usually very low resolution and cannot be used for printing. As a rule of thumb, a you may use a bitmap for a photograph or a screenshot, but all schemes, charts, and graphs should be provided as pure vector files. In cases where this is not possible, we require a high-resolution monochrome bitmap (at least 300dpi, which means approximately 1500px for 10cm width of the image) so that the aliasing effects will not be visible.

Q: How can I produce vector EPS/PDF graphics from MS Word or MS Excel?
A: Modern MS Office programs are able to export documents directly to PDF. Such a document has to be post-processed, for example in the Inkscape editor (open source, can be download from here). The following internet posts give more information about the whole process: How to export Excel plots to a vector image (EPS, EMF, SVG, etc.), Export Excel graphs as vector graphics files (e.g. SVGs)?

Q: May I provide the tables as pre-formatted EPS/PDF files for the layout editing round?
A: No. We always need "raw" data (LaTeX or MS Word formatted) to prepare tables that are consistent with the layout of the journal.
