JavaScript 中的最小值及其关联键

Question

我正在尝试从 Twitter 中识别艺术家。所以我有一条推文，我正在使用 natural for node 对推文进行标记，并将其与使用 Levenshtein 距离将标记与艺术家匹配的艺术家数组进行比较。我的问题是我在实际比较每个标记与艺术家列表并匹配推文所指的那个的逻辑上遇到困难。

以下示例应将 Clean Bandit 作为艺术家。

var saturday = ["Kanye West", "Pharrell Williams", "Paloma Faith", "Burt Bacharach", "Clean Bandit"];

var tweet = "My queen @graciechatto about to go on The Other Stage at Glastonbury #cleanbandit #glastonbury…"

tokenizer = new natural.WordTokenizer(); //new tokeniser

var tweetTokenised = tokenizer.tokenize(tweet); //tokenise the tweet and store it in tweetTokenised

var i , j;

//loop through tokenised tweet    
for(i=0;i<tweetTokenised.length;i++){
    console.log(tweetTokenised[i] + "--------------------------");
    var temp = [];

    //compare token with list of artists performing on saturday    
    for(j=0;j<saturday.length;j++){

        //remove whitespace from the tweet tokens
        console.log(tweetTokenised[i]+ "--->"+saturday[j]); //testing purposes
        var score = natural.LevenshteinDistance(tweetTokenised[i].replace(/\s+/g, '').toLowerCase(),saturday[j].toLowerCase());

        //store score for each token vs artists in a temp dictionary 
        temp.push({
            key:   saturday[j],
            value: score
        });
    }
}

Answer 1

        //sort array from lowest to biggest

        temp.sort(function(a, b) {

            return parseFloat(a.value) - parseFloat(b.value);

        });





        //console.log(temp);

        //get the first object (the smallest in this instance as its been sorted)

        lowest = temp.shift();

        console.log(lowest);

        if(lowest.value < 2){

            distances.push(lowest);

        }

    }

    console.log("printing distances");

    console.log(distances[0].key); //get artist name 

}
