Indeks kesamaan Jaccard<\/a> mengukur kesamaan antara dua kumpulan data. Nilainya bisa berkisar dari 0 hingga 1. Semakin tinggi angkanya, semakin mirip kedua kumpulan data tersebut.<\/span><\/p>\n

Indeks kesamaan Jaccard dihitung sebagai berikut:<\/span><\/p>\n

Kesamaan Jaccard<\/strong> = (jumlah observasi di kedua set) \/ (jumlah di salah satu set)<\/span><\/p>\n

Atau ditulis dalam bentuk notasi:<\/span><\/p>\n

J(A, B) =<\/strong> |A\u2229B| \/ |A\u222aB|<\/span><\/p>\n

Tutorial ini menjelaskan cara menghitung kesamaan Jaccard untuk dua dataset di R.<\/span><\/p>\n

Contoh: Kesamaan Jaccard di R<\/strong><\/span><\/h3>\n

Misalkan kita memiliki dua kumpulan data berikut:<\/span><\/p>\n

 a <- c(0, 1, 2, 5, 6, 8, 9)<\/strong>\nb <- c(0, 2, 3, 4, 5, 7, 9)<\/strong><\/pre>\n
 Kita dapat mendefinisikan fungsi berikut untuk menghitung kesamaan Jaccard antara dua himpunan:<\/span><\/p>\n
 #define Jaccard Similarity function<\/span>\njaccard <- function<\/span> (a, b) {\n    intersection = length<\/span> ( intersect<\/span> (a,b))\n    union = length<\/span> (a) + length<\/span> (b) - intersection\n    return<\/span> (intersection\/union)\n}\n\n#find Jaccard Similarity between the two sets<\/span> \njaccard(a, b)\n\n0.4<\/strong><\/pre>\n
 Kemiripan Jaccard antara kedua daftar tersebut adalah 0,4<\/strong> .<\/span><\/p>\n
 Perhatikan bahwa fungsi tersebut akan mengembalikan 0<\/strong> jika kedua set tidak memiliki nilai yang sama:<\/span><\/p>\n
 c <- c(0, 1, 2, 3, 4, 5)\nd <- c(6, 7, 8, 9, 10)\n\njaccard(c, d)\n\n[1] 0<\/strong><\/pre>\n
 Dan fungsinya akan mengembalikan 1<\/strong> jika kedua himpunan tersebut identik:<\/span><\/p>\n
 e <- c(0, 1, 2, 3, 4, 5)\nf <- c(0, 1, 2, 3, 4, 5)\n\njaccard(e, f)\n\n[1] 1<\/strong><\/pre>\n
 Fungsi ini juga berfungsi untuk set yang berisi string:<\/span><\/p>\n
 g <- c(' cat<\/span> ', ' dog<\/span> ', ' hippo<\/span> ', ' monkey<\/span> ')\nh <- c(' monkey<\/span> ', ' rhino<\/span> ', ' ostrich<\/span> ', ' salmon<\/span> ')\n\njaccard(g, h)\n\n0.142857<\/strong><\/pre>\n
 Anda juga dapat menggunakan fungsi ini untuk mencari jarak Jaccard<\/strong> antara dua himpunan, yang merupakan ketidaksamaan<\/em> antara dua himpunan dan dihitung sebagai 1 \u2013 Kesamaan Jaccard.<\/span><\/p>\n
 a <- c(0, 1, 2, 5, 6, 8, 9)\nb <- c(0, 2, 3, 4, 5, 7, 9)\n\n#find Jaccard distance between sets a<\/em> and b<\/em><\/span>\n1 - jaccard(a, b)\n\n[1] 0.6<\/strong><\/pre>\n
