A Planning-Based Explainable Collaborative Dialogue System

no code implementations19 Feb 2023 Philip R. Cohen, Lucian Galescu

The system does this by inferring users' intentions and plans to achieve those goals, detects whether obstacles are present, finds plans to overcome them or to achieve higher-level goals, and plans its actions, including speech acts, to help users accomplish those goals.

Cogent: A Generic Dialogue System Shell Based on a Collaborative Problem Solving Model

no code implementations WS 2018 Lucian Galescu, Choh Man Teng, James Allen, Ian Perera

We implemented the model in a dialogue system shell (Cogent) that al-lows developers to plug in problem-solving agents to create dialogue systems in new domains.
