Similarity score

Each report includes a similarity score that indicates the level of similarity detected in your document. This score is calculated by dividing the number of matched words by the total word count in the document. For instance, if your document consists of 1,000 words and the similarity score is 21%, it signifies that there are 210 matched words present in your document. This provides a clear understanding of the extent of similarities identified during the analysis.
