Information overload is a growing problem for physicians and patients. Dynamic Categorization helps manage this by organizing documents into relevant, manageable categories, improving information retrieval.

Area of Science:

  • Information Science
  • Medical Informatics

Background:

  • Physicians and patients face increasing publication volumes, leading to information overload.
  • Current query reformulation tools are insufficient for imprecise information needs or highly relevant document sets.
  • Ranked document lists offer limited context regarding relevance to the query or inter-document relationships.

Purpose of the Study:

  • To propose and evaluate Dynamic Categorization as a method to reduce information overload.
  • To ensure categorized documents remain relevant to the initial user query.
  • To create manageable document categories for improved usability.

Main Methods:

  • Developed a knowledge-based approach called Dynamic Categorization.
  • Applied Dynamic Categorization to group relevant documents.

  • Utilized re-categorization within large initial categories to create subcategories.

    • Main Results:

    • Dynamic Categorization successfully relates documents to the initial query.
    • Re-categorization within large categories effectively reduces document numbers in subcategories.
    • The approach maintains a clear relationship between documents and the original query throughout categorization.

    Conclusions:

    • Dynamic Categorization is an effective knowledge-based strategy for mitigating information overload in document retrieval.
    • This method enhances information access by organizing large document sets into relevant and manageable categories.
    • Subsequent categorization steps further refine document organization, improving user experience and information discovery.
