It presents a comparative analysis of different strategies, including Random, Form-based, and LLM-guided approaches, across various metrics such as Accuracy, Coverage, Precision, F1 score, False label rate, Efficiency, Mean turns, and Mean words. The findings consistently show that LLM-guided strategies significantly outperform both Random and Form-based methods, demonstrating higher accuracy and better overall performance in metadata extraction tasks. The implications suggest a strong trend towards leveraging AI-powered solutions for document analysis and information retrieval.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/document-metadata-extraction-multimodal-194706/194706/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/document-metadata-extraction-multimodal-194706/194706.png","ImageObject",442,249,{"name":42,"@type":43},"Adam","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-01","2026-09-03",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",6,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What
