What is a Similarity Detector?

A similarity detector, also known as a plagiarism detection software, is a technology that identifies potential plagiarism by measuring textual similarities and matches. Similarity detection provides a rate or percentage of similarities within a text.

Compilatio analyzes your documents to detect and measure matches with various types of sources.

  • The objective: to find all the similarities and in all their forms (content copied identically, reworded and translated).


Examples of documents to analyse: dissertation, thesis, internship report, doctoral thesis, scientific article, press article, press review, etc.

What is a Similarity Rate?

At the end of the analysis of your documents in Compilatio, you receive a similarity rate.

The similarity rate measures the degree of matching between two documents. It represents the quantity of passages in the document analysed that are similar to resources from the Internet, scientific publications, student work and other academic content.

It is useful to measure the similarity rate to assess the originality of a work or content.

Focus on Cross-lingual Plagiarism Detector and Reformulation Detector

The cross-lingual similarity detector or cross-lingual plagiarism detector and the reformulation detector are available for several languages:

  • the main European languages: English, French, German, Spanish, Italian, Portuguese, Dutch, Polish, etc.
  • other languages from all over the world: Russian, Arabic, Chinese, Turkish, etc.
     

Teaching use case: 

A student draws heavily on a source and borrows passages which he rewrites using a reformulation tool.
When consulting the analysis report, the teacher suspects significant use of a source. With one click, he launches a multilingual comparison of the document with the source. All the reworded or translated passages are detected, and the score is updated with any additional similarities.

The teacher can demonstrate factually and quantify the use of the source, despite the rewording or translation.

To benefit from the "cross-lingual/multilingual similarity detection" and "reformulation detection" functionalities, your institution must have the Magister+ package.
