Intentional copying of another's text and passing it off as one's own, careless or inaccurate citation of the literature used, or failure to cite (even unintentionally) a source used can be considered plagiarism.
Plagiarism can arise both intentionally and through ignorance or negligence, so it is important to work properly with information sources used in writing term theses and other academic texts.

Thesis originality check in anti-plagiarism systems
After submitting the final thesis to IS STAG, the thesis is automatically sent for originality checking via system for plagiarism detection Theses.cz. The result of the verification from Theses.cz is automatically stored in IS STAG. The check is performed only once.
If you want to test your thesis before uploading it to IS STAG, you can use the Odevzdej.cz system, which will compare your thesis with the records of the Theses.cz database, among other things. You do not need to log in or register to check, but you only have limited rights.
The university also has access to the Turnitin anti-plagiarism system. Turnitin is most effective in checking texts in English. If you wish to check your English written work, please contact Ms Zaan Bester at the Language Centre.

Even in a text in which you have handled the sources correctly (they are properly cited), the plagiarism checker may find similarities. However, a mere percentage of agreement means nothing in itself. For example, when quoting passages from laws whose wording must be presented unchanged, the similarity can be in the tens of percent. Thus, a high rate of agreement may indicate a significant number of (even perfectly proper) citations, but it may also indicate a low proportion of the original text. The result of the check must be assessed and evaluated by the supervisor or opponent(s) of the paper.
Turnitin is an anti-plagiarism system or tool for verifying the originality of text.
Its main purpose is to prevent plagiarism, so it is connected to the university's LMS Moodle installation.

For authors who wish to check their article outside of Moodle (before publication in a peer-reviewed journal), the University Library will provide a similarity check via Turnitin. Please contact Ms. Veronika Kolinová or Ms. Blanka Jankovská.
