Emospeech Dialogue Toolkit
Participant : Lina-Maria Rojas Barahona [correspondent] .
The Emospeech Dialogue Toolkit is a multi agent architecture for developing man/machine dialog systems in the context of a video game. It includes the following agents;
-
Midiki Dialogue Manager: We extended and improved the open source MIDIKI (MITRE Dialogue Toolkit) software to support the multi-agent architecture and the configuration from a relational database.
-
Wizard of Oz: We implemented two Wizard of OZ interfaces which allow a human to interact with other agents in the dialogue architecture. The free-wizard acts as a dialogue manager and permits a chat between two humans the player and the Wizard while simultaneously storing all interactions in a database. In contrast, The semi-automatic wizard, connects the Wizard with Midiki, whereby the Wizard interprets and adjusts Midiki generation.
-
Answer Selection: We trained a classifier with Conditional Random Fields that chooses the most plausible response to a player utterance.
In addition, we trained a Logistic Regression Classifier for the interpretation agent that communicates with MIDIKI.
The dialogue agents communicate with the Game Agent, Speech Recognition and/or Chatbox agents developed by the Parole team. The Wizard of Oz, in which a human simulates a dialogue system, is used to collect dialogue data which can be used for training the interpreter and/or the Answer Selection Classifier. Moreover, a Dialogue Configuration Tool has been implemented for the configuration of several dialogues for different game scenarios by configuring the characters and goals in the game and the goals to be discussed in each dialogue.
