  • A two-layer dialogue framework for authoring social bots
    Rensselaer Polytechnic Institute
    Alexa Prize SocialBot Grand Challenge 1 Proceedings
    2017
    In recent years, chat-bots that assist people’s daily life gained tremendous popular- ity, such as Siri, Cortana, Alexia and Google assistant. Typically, conversations with chat-bots are task orientated and brief. In this work, we explore creating social bot that can complete task and entertain user.

  • A chatbot by combining finite state machine, information retrieval, and bot-initiative strategy
    Seoul National University
    Alexa Prize SocialBot Grand Challenge 1 Proceedings
    2017
    In this work, we designed a conversational system by combining a finite state method, a retrieval model and a machine-initiative dialogue strategy. By using the machine-initiative strategy, most of the user queries are handled by the finite state machine which models predefined dialogues. If the user’s utterance is out of the range of modeled dialogues, the retrieval model processes the input. On comparative

    University of Trento
    Alexa Prize SocialBot Grand Challenge 1 Proceedings
    2017
    Open–domain dialogue systems should be able to cover a very large set of domains and at the same time keep the user engaged in the interaction. Current approaches to dialogue modeling are divided between domain–independent, non–modular approaches using sequence–to–sequence models and the domain–specific modular systems developed for task–based dialogue. Furthermore, user engagement in dialogue, addressed
