Terms and definitions



System "Antiplagiat" (service)

Online tool for working with text documents with user interface on the web-site.

Text reuse

A fragment of the document text that contains the text or a fragment of the source text and is not formatted in accordance with citation rules


A fragment of the document text that contains the text or a fragment of the source text, the author or co-author of which is the author of the verified document


A fragment of the document text that contains the text or a fragment of the source text and formatted in accordance with the rules of citation, with full bibliographic information about the source. Also citation includes common expressions, bibliography, fragments of text found in sources from the collections of regulatory documents.

Text reuse percentage

The proportion of all found text reuses in relation to the total size of the verified document in characters

Self-citation percentage

The proportion of all found self-citations in relation to the total size of the verified document in characters

Citation percentage

The proportion of all found citations in relation to the total size of the verified document in characters

Originality percentage

The proportion of all document text fragments that were not found in the sources used for verification, in relation to the total size of the verified document in characters


The result of checking the text for reuse:

  • Brief report - is a percentage of originality, list of text sources.
  • Full report - is a percentage of originality, list of text sources, the full text of the document, marked with found reused text blocks.

Report share

The ratio of the amount of text reuse that is accounted for in this source to the total size of the document. That is, if the same text was found in several sources, it is considered only in one of them.

Text share

Ratio of the volume of the text reuse on this source to the total size of the document. Shares in the text are not summarized by sources.

Report blocks

The number of text blocks reused from the source, taking into account the intersections of all found sources.

Text blocks

The number of text blocks reused from a source without regard to other found sources.

Collection (search module)

The software module of the corporate version of the system "Antiplagiat", implementing the search for text reuse. The module uses a search index or a special computational algorithm to build reports. The system can have several collection. Search modules may differ in purpose, for example:

  • Internet search;
  • Citations;
  • Russian State Library (RSL) collection;
  • Lexpro collection;
  • eLIBRARY collection;
  • National Library of Belarus (NLB) collection.

Once you have access to several search collections, you can build both individual reports and a single report for all search collections.

Some collections perform searches across specialized databases with the casts of the texts of the source documents, but to obtain access to the selected search module doesn't mean getting access to the full texts of the documents it can find this collection. In the received reports, links to the documents will be indicated (their names will also be given), and when viewing the source text, it will contain fragments that coincide with the document being checked.


Software that allows users to view pages on Internet sites and access files and software associated with those pages. For example, Internet Explorer, Google Chrome, etc.

Text metrics

Semantic characteristics for each uploaded document.

Purpose and conditions of use

The service is designed to check text documents for plagiarism. As a result of the scan, users receive text reuse reports. The report contains information on the sources and indicators of text reuse by source, as well as detailed information with the indication of those fragments of the checked document that have been identified as text reuse. The identification is accompanied by the presentation of the matching text fragment of the borrowing source and/or the reference to the original (URL). As a result of the document check, the user can determine which part of the document is written independently and which part is reused.

To use the service you need:

  • Connect to the Internet;
  • Install a browser or use the browser of one of the most common types built into your operating system (MS Internet Explorer version 11 and above, Mozilla Firefox version 58 and above, Opera version 51 and above, Chrome version 64 and above).

The results of work with the system "Antiplagiat" are not the basis for claims of copyright violations, the service is aimed at use only for information purposes. In other words, we do not declare that a particular text is plagiarism, but only inform you about the presence of the same or similar text fragment. It is possible that when working with the service, you will find the text copied from other sources, including the possibility that the downloaded document is the original source. In any case, when working with the service, be careful, try to be objective and do not rush to conclusions.

The fact that one or more of the report's links to the open sources on the Internet at the time of viewing the report do not work is not a reason to remove these links from the system's index. Texts at the links' addresses were indexed, before being deleted / moved, they were available to third parties, could be read, copied or otherwise used. Also, they could be stored in the cache of search engines and web archives, where they could still be found.

  • Correction of the list of considered sources in the report – allows to consider or not to consider the sources specified by you in the report.
  • Change source type - allows you to change the source type of your choice.

The system divides sources into three types: "Reuses", "Self-citations" and "Citations".

While the report is building the system automatically marks the type of source: "Reuses" - red color, "Self-citations" - yellow color and "Citations" - green color.
