10章AIを活用したアプリケーションの構築
この章では、コンテンツ生成の全工程をAIで自動化し、その内部で実行するプロンプトやコードに対して、プロンプトの5つの原則を適用します。本章で扱うアプリケーションは、ユーザーへのインタビュー質問の回答に基づき、そのユーザーの文体でブログ記事を作成します。このアプリケーションは当初、Saxifrage blog※1にも記事として掲載されました。
10.1 生成AIによるブログ記事の執筆
生成AIを使用してブログ記事執筆アプリケーションを作成する単純なアプローチは、「Write a blog post on {blogPostTopic}（{blogPostTopic}についてブログ記事を執筆してください）」とGPTに要求するコードをPythonで書くことです。この結果得られるコンテンツは、質はそれなりに良いですが、そのトピックについての価値ある意見や独自の経験は含まれていないでしょう。また、コンテンツは短く、一般的になりがちで、Google検索で上位にランクインする可能性は低いです。
より洗練されたアプローチとして、さらなる指示を加えた長めのプロンプトを構築することが考えられます。指定された執筆口調、ブログ記事の構成、含めるべきキーワードなどの詳細を追加できます。一般的なブログ記事執筆のプロンプトの例※2は以下のとおりです。
