Matches by word count or %

Excluding small matches allows you to exclude matching against sources with a small amount in common with the submission. For example, it's possible to exclude matches fewer than 20 words in total, or less than 10% in total.

The percentage is based on the total word count of the student's submission. For example, if a student submitted a 5,000 word submission, and you have this set to 10%, it will exclude sources of less than a 500 word match.

1.To exclude text from the report according to its size, click the red filter icon from the similarity toolbar.

2.From the Filters and Settings side panel, use the radio and text boxes to determine which exclusions should apply to the submission you are viewing. You can exclude sources that are less than a certain number of words, or a certain percentage of words. For example, filtering by 10 words will exclude all sources that have a cumulative number of matching words that are less than 10 words in length.
