Journal of Philosophical Investigations (JPI) was established in 2007 in the department of Philosophy of the Faculty of Literature at the University of Tabriz. But before that, philosophical articles were published in an old journal called the journal of the Faculty of Literature. This old journal was the first journal of Tabriz University to be published in four issues per year, one of which was dedicated to the philosophical articles of the department of Philosophy and professors of philosophy. But this old journal was divided into four journals in 2006, and the Journal of Philosophical Investigations was one of them. Until the summer of 2014, emeritus professor Yahya Yasrebi, Professor of Philosophy and Mysticism at Allameh Tabatabaei University (Tehran), was the editor of this journal, and now Dr. Muhammad Asghari, Associate Professor of the Department of Philosophy- University of Tabriz, is the Editor-in-Chief of this journal. Initially, the Journal of Philosophical Investigations was published twice a year. Due to the great response from the philosophical audience, it was decided to publish it four times a year, and as a result, this journal was officially known as the Journal of Philosophical Investigations. This quarterly published the first issue of articles on Plato's philosophy, Greek philosophy, and Islamic philosophy, and since 2012 has published one of its issues (autumn every year) in English.

9. Plagiarism Check

Journal of Philosophical Investigations ( University of Tabriz) Editor's Board agreed that plagiarism could not be accepted and approved because it was agreed by those who agreed to the demands after agreeing to plagiarism / approving articles submitted for approval at this journal will use Turning checking software (Plagiarism Checker X for English language articles & Samimnoor  for Persian language) as a tool to verify the text in the article script and the final version of the article is ready for use. A maximum of 20% is approved for the paper sent. If we find more than 20% of the index agree, the article will be returned to the responsible author to be corrected and sent back. Of course, in the process of submitting an article by the authors, the journal takes a written commitment from the responsible author, signed by him/her, and the author promises that the article does not contain any plagiarism. 

Definition of Plagiarism:

Plagiarism involves "the use or placement of language imitations and the thoughts of other writers and their representation as someone's original work."

 Policy:

Papers must be original, not published, and not wait for publication elsewhere (such as in journals, books, etc...). Any material that is taken verbatim from other sources must be clearly explained about differing from this original text by (1) indenting, (2) using quotes, and (3) using sources.

Any text with an amount that exceeds the fair use standard (herein is determined as more than two or three sentences or the equivalent) or graphic material that is reproduced from other sources, requests permission from the copyright holder, and, requests, requests, and requests the source for help; e.g., previous publications.

When plagiarism is denied, the Editor in Chief is responsible for the review of this paper and will ask for steps that correspond to the level of plagiarism issued in this paper in accordance with the following instructions:

 The level of plagiarism:

Minor: Short sections of other articles are traced without significant data or ideas taken from other papers.

Action: A warning is given to the author, and a request to change the text and citations correctly to the original article was made.

Intermediate: Most papers are plagiarized without citations matching the citation paper.

Action: Articles submitted were rejected and submitted, and the article was further rejected for one year.

 Severe: Most papers are traced, which produces reproducing original results or ideas presented in other publications.

Actions: This paper was rejected and forbidden further authors for three years.

 It is understandable because all authors are responsible for the contents of the papers they send because they all read and discuss the Journal of Philosophical Investigations (University of Tabriz) Copyright and Licensing. If the sentence is handed down for plagiarism, all writers will be subject to the same sentence.

If a second plagiarism case by the same author is identified, a decision on the actions to be enforced will be made by the Editorial board (Editor in Chief, and Editorial members) with the Chief Editor in Chief. The author is forbidden to submit further articles forever.

This policy also applies to materials reproduced from other publications by the same author. If an author uses text or images that have been previously published, the appropriate paragraph or number must be published and previously referenced.

Authors must exclude sources from previously published material and obtain permission from the original author and publisher. If someone sent the manuscript to the Journal of Philosophical Investigations (University of Tabriz) with a significant overlap with the manuscript sent to another journal simultaneously, and this overlap was found during the review process or after the publication of both papers, another journal editor participated who reported it as a case of severe plagiarism. Significant overlap means the use of identical or more identical numbers and identical or slightly verified text for some or more papers. For plagiarism itself, less than half the paper but more than one-tenth of the paper, the case must be more than medium plagiarism. If plagiarism is limited to the method, this case must be considered minor plagiarism.

If an author uses some previously published material to clarify the presentation of new results, previously published material must confirm and update for this publication to be published. Permission to republish must be obtained from the copyright holder. In publications that are published in the process of publication and then submitted for publication in the Journal of Philosophical Investigations (University of Tabriz) in either a connected or publication form, the author must discuss the name of the process and publication and publication to obtain permission to republish from the copyright holder. The editor may decide not to accept this paper for publication.

However, an author is permitted to use material from unpublished presentations, including visual displays, in subsequent journal publications. In the case of submitted publications, originally published in other languages, the original title, date, and journal of the publication must be identified by the author, and copyright must be obtained. Editors can accept such translated publications to attract the attention of a wider audience.
