Top 7 Free Plagiarism Detection Tools

What is Text Similarity?

Text similarity, as the name suggests, is to compare two or more different pieces of text to see how closely they resemble each other. Text similarity can mean a number of different things – most commonly, it can either refer to what is called semantic similarity, or to what is called lexical similarity. Lexical similarity is a form of similarity which focuses entirely on words, and how similar they are to each other, without any reference to what the words themselves actually mean. Because of this, lexical similarity is considered to deal purely with surface level similarities. Semantic similarity is more concerned with the meaning of the words – their surface similarity is beside the point. Semantic similarity is what is brought into play when the words of a text are similar to one another by necessity.
