Bukan Alexa ataupun Siri, Program Sederhana dengan Ide Awal dari Eliza!

Hari ini saya belajar bagaimana Artificial Intelligent awalnya ditemukan. Bukan langsung melejit menjadi Siri ataupun Alexa, awal mulanya adalah sebuah technical support bernama Eliza. Input dan outputnya berupa text dimana jika kita mengetikkan sesuatu, secara otomatis akan dibalas dengan hal yang terkait dengan apa yang ditanyakan.

Program yang saya buat di kelas ini merupakan program sederhananya dimana ketika user mengetikkan sesuatu, akan dibalas dengan jawaban-jawaban acak yang sudah saya siapkan dalam program.
