Overview

Large Language Models are sensitive to prompt phrasing. Prompt Mining helps discover better templates that occur more frequently in the corpus or are clearer to the model. Here are examples from the paper mapping manual prompts to mined prompts:
Manual PromptMined Prompt
x is affiliated with the y religionx who converted to y
The headquarter of x is in yx is based in y
x died in yx died at his home in y
x is represented by music label yx recorded for y
x is a subclass of yx is a type of y
We implement a lightweight approach with Instructor to extract clearer prompt templates.

Example

<?php
require 'examples/boot.php';

use Cognesy\Instructor\StructuredOutput;
use Cognesy\Instructor\Extras\Sequence\Sequence;

class PromptTemplate {
    public string $prompt_template;
}

class GeneratePromptTemplates {
    public function __invoke(string $prompt) : array {
        $system = 'You are an expert prompt miner that generates 3 clearer, concise prompt templates.';
        return (new StructuredOutput)->with(
            messages: [
                ['role' => 'system', 'content' => $system],
                ['role' => 'system', 'content' => $prompt],
            ],
            responseModel: Sequence::of(PromptTemplate::class),
        )->get()->toArray();
    }
}

$prompt = 'France is the capital of Paris';
$templates = (new GeneratePromptTemplates)($prompt);
dump($templates);
?>
