Abstract
Media center merupakan sebuah sistem pelayanan terintegrasi bagi masyarakat Surabaya. Melalui media center masyarakat dapat berpartisipasi memberikan opini atau melaporkan hal-hal yang terkait dengan pembangunan kota Surabaya. Informasi pelaporan masyarakat bisa negatif bisa positif untuk itu perlu dilakukan pengelompokan. Selama ini pengelompokan dilakukan secara manual. Hal ini membutuhkan waktu yang lama, untuk itu dibutuhkan metode pengelompokan yang lebih cepat dan akurat.
