Prolog and Patterns
a50recipeConfirm: Confirming a Recipe in patterns.pl
After the user selects a recipe, the agent should confirm the user’s choice. We foresee two potential situations for this conversation, which can be accommodated by making two a50recipeConfirm patterns. After the agent uses ‘recipeCheck’ to ask if the user can look over the recipe information to decide if they want to cook that recipe, the user could confirm (1), or deny (2).
In patterns.pl, make the a50recipeConfirm patterns for the two scenarios mentioned above. Look at Dialogflow for the appropriate Intent identification naming. If the user says it does not want to choose that recipe, we need to go back to a50recipeSelect. How would one do this?
In responses.pl fill in ‘text(recipeCheck, “”)’ response.
c43: Farewell in patterns.pl
Make a pattern that encapsulates the following conversation called c43.
% Pattern C4.3: Closing Farewell (Agent)
% Example:
% A: goodbye
% U: bye
% Instruction:
% 1. Introduce an intent ‘farewell' for saying goodbye by adding this intent to your Dialogflow
% agent (for user recognition) and the response.pl file (for agent text generation).
% 2. Add a pattern here where the agent initiates (i.e. starts) saying goodbye and then the user is
% allowed to say goodbye.
% 3. Add the c43 pattern you introduced to the agent’s agenda.
Extend
Introduce a last topic check to your farewell pattern to see if the user wants anything else or wishes to find another recipe. If they do restart the entire conversation. Note: this can be done using [agent, restart] which resets the agent agenda to the initial agenda at the start of session.
Test it Out
Add c43 to the agent agenda in the dialog_init file.
Run the agent all the way through from greeting to closing.
