How to send long articles for summarization?

Here are some notes I have made on the issue. I have used the first strategy, Map Reduce, with success.

  • Smaller chunks allow for more understanding per chunk but increase the risk of split contextual information. Let’s say you split a dialog or topic in half when chunking to summarize. If the contextual information from that dialog or topic is small or hard to decipher per chunk that model might not include it at all in the summary for either chunk. You’ve now taken an important part of the overall text and split the contextual information about it in half reducing the model’s likelihood to consider it important. On the other side you might produce two summaries of the two chunks dominated by that dialog or topic.

    • Map Reduce
      • Chunk document. Summarize each chunk, then summarize all the chunk summaries. Using this currently in embed_solr_index01.php.
    • Stuffing
      • Summarize entire document all at once, if it will fit into prompt.
    • Refine
      • Chunk document. Summarize first chunk. Summarize 2nd chunk + 1st chunk summary. Summarize 3rd chunk + 1st and 2nd chunk summary. And so on…
