Automated Online Assistant is typically used by businesses, governments and NGO’s that deploy chatbots to automate live chat in call centers. Automated Online Assistants have the ability to provide customer service during 24 hours a day and 7 days a week, and may, at least, be a complement to customer service by humans. This system can be described as an intelligent agent that functions to perceive the needs of customers in order to perform proper reactions by various structured systems, such as question answering.
