This study introduces a model for automated clinical information retrieval using generic queries derived from user questions. It enhances medical data access by leveraging the Unified Medical Language System (UMLS) for efficient search and filtering.

Area of Science:

  • Medical Informatics
  • Natural Language Processing
  • Information Retrieval

Background:

  • Clinical users face challenges in retrieving specific information from vast medical literature.
  • Existing information retrieval systems often lack the ability to understand complex clinical queries effectively.

Purpose of the Study:

  • To develop and evaluate a model for automated information retrieval tailored to clinical users' needs.
  • To create a system that translates specific clinical questions into general-purpose queries for efficient data retrieval.

Main Methods:

  • Analyzing user questions to identify syntactic and semantic patterns for creating generic queries.
  • Utilizing natural language processing (NLP) techniques to match user input with relevant generic queries.
  • Employing the Unified Medical Language System (UMLS) Metathesaurus and Semantic Network for concept and relation extraction.

  • Automating information source selection, retrieval strategy composition, execution, and result filtering.

    • Main Results:

    • The model successfully translates specific clinical information needs into generic queries.
    • Integration with UMLS facilitates accurate medical concept identification and semantic relation utilization.
    • Automated processes streamline the information retrieval workflow from query to filtered results.

    Conclusions:

    • The proposed model offers a robust approach to automated information retrieval for clinical settings.
    • Leveraging UMLS and NLP significantly improves the efficiency and relevance of clinical information access.
    • Further research and implementation are ongoing to refine the system's performance and user experience.
