Prolog and Patterns

We will begin with implementing a pattern for allowing a user to express they are done, and then get back to what is still missing to implement requests to remove a filter.

...

There is still one thing missing… Just by talking the agent will not change the page that is displayed. Recall that you have created two pages for the a50recipeSelect pattern for https://socialrobotics.atlassian.net/wiki/pages/createpage.action?spaceKey=PM2&title=2025%20Capability%205%3A%20Filter%20Recipes%20by%20Ingredients%20and%20Cuisine [TBU]Filtering by Inclusion . When the agent grants the user’s request we still need to make sure that the second recipe recommendation page showing the recipe pictures is displayed. To make that happen, we need to change the condition for showing that page. We need the store the fact that the user requested this. The idea is to use the conversational memory of the agent for that and update it with this information. Therefore, when the agent grants the user's request, the version of that pattern should end with the agent updating its memory using an [agent, update(['show'='true'])] actor-intent pair. To change the condition for showing the page in the html.pl file, we can then use the memoryKeyValue/2 predicate defined in the dialog.pl file to add an alternative condition for showing this page.

...

This completes the implementation of all the different cases for the agent’s response. The patterns for removing filters should now work!

What you do visually for this capability is up to you.

Test it Out

Now https://socialrobotics.atlassian.net/wiki/pages/createpage.action?spaceKey=PM2&title=2025%20Run%20your%20Conversational%20Agent [TBU]Run your Conversational Agent again and try to remove some of the recipe constraints after you added them.
