The Sorensen-Dice similarity between marked and masked (using bigrams with padding), rounded to 1 decimal place is:Group of answer choices0.50.60.70.8

To answer this question, we first need to understand what the Sorensen-Dice similarity is and how it is calculated.

The Sorensen-Dice similarity is a statistical tool used to gauge the similarity between two samples. It is calculated using the formula:

2 * (Number of common characters) / (Total number of characters in both strings)

In this case, we are looking at the similarity between the words "marked" and "masked". We are using bigrams with padding, which means we are looking at pairs of letters in each word, and we are adding a space at the beginning and end of each word.

The bigrams for "marked" are: " m", "ma", "ar", "rk", "ke", "ed", "d ". The bigrams for "masked" are: " m", "ma", "as", "sk", "ke", "ed", "d ".

The common bigrams are: " m", "ma", "ke", "ed", "d ".

So, the Sorensen-Dice similarity is: 2 * 5 / (7 + 7) = 0.71

Therefore, rounded to 1 decimal place, the Sorensen-Dice similarity between "marked" and "masked" is 0.7.
