In this article, we will explore a new summarization technique called Chain of Density Prompting. This technique, introduced by Salesforce and MIT, aims to create summaries that provide key details and are centered around the main entities in the text. The method proposes a prompt that first creates a standard GPT-4 summary and then iteratively looks for missing entities and adds them to the summary without increasing its length.
To demonstrate the effectiveness of this technique, we will run an experiment comparing a summary generated using the vanilla summarization approach with a summary generated using the Chain of Density Prompting technique.
The Chain of Density Prompting technique involves three steps. First, we generate a standard GPT-4 summary of the text we want to summarize. Then, we iteratively find missing entities and incorporate them into the summary without increasing its length. Finally, we group the bullet points together to create a final summary that is more digestible and easier to read.
To implement the Chain of Density Prompting technique, we use the AI video summarizer plugin. We start by summarizing a YouTube video using the vanilla approach and then repeat the process using the Chain of Density Prompting technique. The results show that the Chain of Density Prompting technique produces summaries that are denser and more entity-centric, making them easier to read and understand.
In conclusion, the Chain of Density Prompting technique is a promising approach to text summarization. It allows for the creation of summaries that provide key details and are centered around the main entities in the text. By incorporating missing entities without increasing the length of the summary, the technique produces more informative and concise summaries. This technique can be particularly useful for summarizing YouTube videos and other forms of multimedia content.
