Processing of larger PDF documents
During testing, large PDF documents (NIST IR 8428 or other research articles for example) exceed the token output window of the LLM that's in use. I suggest one of two recursive solutions: separate large documents into smaller parts and create individual cards for each part. a. Bad: may create section headers that don't make sense when attempting to determine the original document those section headers were created from. Goes against what appears to be the general theory behind Recall. b. Good: Summaries themselves maintain the maximum output token window for each section. Page and summary separation and ultimate compression to a maximum token output window. a. Bad: Maximum token output requires total compression of all previous summaries into one condensed summary. Substantial context may be lost due to the lack of reference back to the original source material when compressing summaries. b. Document is kept in one card. An example pseudo-function for option 2 is as follows: FUNCTION summarizeLargePDF(pdfFilePath, maxInputTokens, maxOutputTokens, llm): Initialization currentPage = 1 totalTokens = 0 currentSummary = "" allSummaries = [] # Array to hold section summaries sectionStartPage = 1 Recursive Page Processing Function (Nested) FUNCTION processPage(pageNumber): pageText = extractTextFromPage(pdfFilePath, pageNumber) pageTokens = countTokens(pageText) Check if adding this page exceeds input token limit IF (totalTokens + pageTokens) > maxInputTokens: Summarize the section sectionEndPage = pageNumber - 1 sectionText = extractTextFromPages(pdfFilePath, sectionStartPage, sectionEndPage) sectionSummary = llm.summarize(sectionText, maxOutputTokens) Add summary to the list and reset section allSummaries.append(sectionSummary) sectionStartPage = pageNumber totalTokens = 0 totalTokens += pageTokens currentPage += 1 Recursive call for the next page processPage(currentPage) Main Function Logic processPage(currentPage) # Start recursive processing Final Summarization of all Section Summaries WHILE allSummaries.length > 1: Combine and re-summarize in pairs newSummaries = [] FOR i = 0 TO allSummaries.length - 1 STEP 2: combinedText = allSummaries[i] + allSummaries[i+1] newSummary = llm.summarize(combinedText, maxOutputTokens) newSummaries.append(newSummary) allSummaries = newSummaries The single remaining summary is the final result finalSummary = allSummaries[0] RETURN finalSummary
