Conversations between human beings and computers have been a mainstay of science fictions movies for decades. Remember the HAL 9000 in director Stanley Kubrick's groundbreaking 1968 epic "2001 - A Space Odyssey?" Remember Joshua, the computer in the 1983 hit "War Games?" Remember Kirk and Spock issuing verbal commands to the Starship Enterprise's onboard computer? In the second decade of the 21st century, conversational interfaces have transcended fiction to become a reality, and the next big thing in consumer and enterprise mobile application development. Paired with artificial intelligence, chatbots help to simplify mobile communication between users and services. As in human conversation, well-chosen wordings allow users to book a table in a restaurant, arrange a taxi to the airport, buy an airline ticket, and more. This on-demand session video from the Oracle Code Online event in June 2017 explores a developer perspective on chatbots.
