Service: Chatbot Sigma

Responsible organisation: Agência para a Modernização Administrativa - AMA (Central-Government)

Chatbot "Sigma" - ePortugal.gov.pt Sigma is the chatbot of the portuguese public services portal (eportugal.gov.pt). This chatbot responds, in natural language, to user interactions with the information available on the information pages on public services available on the ePortugal portal. In addition to answer with information, the user can, in a conversation, change his address on the Citizen Card (Portuguese identification document). In the last Portuguese elections, the citizen was able, through a conversation with Sigma, to know where to vote. The administration and configuration of Sigma goes through 3 platforms: LUIS - platform that interprets natural language. When trained, he's able to identify what the user wants to know (intention) about a certain service (entity). QnA - platform where the ePortugal portal services are loaded so that the bot can identify them, and also where chitchat interactions are loaded (quick chat). Cognitive Services APIs Reference - platform where groups of synonyms are loaded in form of keywords to facilitate the bot to interpret a service.
