计算两个字符串之间的匹配词数

Question

Hello I would like to ask some help how I can do this in Jquery

Count the number of matching words (in order) between two strings so I can generate accuracy.

// Example
string1 = "The lazy fox jumps over the fence" // (7 words)
string2 = "The lazy dog jumps under a fence yesterday" // (8 words)

Output: 4

Accuracy is (4 correct words/7 words to check) = 57%

Any idea will be appreciated

Answer 1

You could split each string to words and match the same words by using filter

 function getWords(str) { return str.split(" ").filter(Boolean); } function getMatchedWords(words1, words2) { return words1.filter((word) => words2.includes(word)); } const string1 = "The lazy fox jumps over the fence"; const string2 = "The lazy dog jumps under a fence yesterday"; const words1 = getWords(string1); const words2 = getWords(string2); const matchedWords = getMatchedWords(words1, words2); const ratio = +((100 * matchedWords.length) / words1.length).toPrecision(2); console.log(ratio);

Answer 2

Make sets from strings containing word, position tuples then intersect them via logical conjuction & . Depending on whether or not it should be case sensitive apply toUpperCase operation before. The result set contains matching words from all strings.

By this way you can test any number of strings for the extinct they match to each other.

I'm on mobile, writing code is not the case, sorry.
