Extracting Ingredients from Menu

When I began this project, I wrote a prompt and utilized the Text Completions API to extract the ingredients. I employed the One Shot Prompt to guide the API in generating the results in a recognizable format and put effort into parsing it.

As soon asOpenAI introduced function calling, I promptly refactored the code to incorporate it, and it greatly simplified the process. The results are now provided in JSON format, which further streamlines the workflow.

Here's the function:

{
    name: "get_ingredients",
    description: "List the ingredients given the list of dish.",
    parameters: {
        type: "object",
        properties: {
            ingredients: {
                type: "array",
                items: {
                    type: "object",
                    properties: {
                        name: { type: "string", description: "Name of ingredient, e.g. pork belly, ginger, garlic, fish sauce" },
                        quantity: { type: "string", description: "Quantity e.g. 1kg, 2pcs, 3cups, 4tsp, 5tbsp" },
                        dish: { type: "string", description: "Name of dish, e.g. adobo, pasta, stew" },
                    }
                }
            }
        },
        required: ["people"]
    }
}

And a sample result:

{
  role: 'assistant',
  content: null,
  function_call: {
    name: 'get_ingredients',
    arguments: '{\n' +
      '  "ingredients": [\n' +
      '    {\n' +
      '      "name": "beef",\n' +
      '      "quantity": "1 pound",\n' +
      '      "dish": "beef broccoli stir fry"\n' +
      '    },\n' +
      '    {\n' +
      '      "name": "broccoli",\n' +
      '      "quantity": "2 cups",\n' +
      '      "dish": "beef broccoli stir fry"\n' +
      '    },\n' +
      '    {\n' +
      '      "name": "soy sauce",\n' +
      '      "quantity": "2 tablespoons",\n' +
      '      "dish": "beef broccoli stir fry"\n' +
      '    },\n' +
      '  ]\n' +
      '}'
    }
}
