    This study introduces a new method for creating multidimensional semantic spaces to integrate biomedical data. This approach enhances information processing and data analysis through semantic annotation and a novel visualization tool.

    Area of Science:

    • Biomedical Informatics
    • Data Science
    • Knowledge Representation

    Background:

    • Semantic integration of biomedical resources is crucial for data analysis but remains challenging.
    • Biomedical ontologies and thesauri facilitate integration via semantic annotation into a common semantic space.
    • Existing methods lack a multidimensional representation for diverse biomedical research perspectives.

    Purpose of the Study:

    • To propose a novel multidimensional representation for biomedical semantic spaces.
    • To develop a method for constructing these spaces from annotated biomedical data.
    • To introduce a visualization tool for exploring the generated semantic spaces.

    Main Methods:

    • Knowledge normalization: Organizing concepts from resources like ontologies into hierarchical dimensions.

    Published on: September 5, 2025

  • Data normalization: Reducing data annotations to points within the multidimensional space.
  • Developed the 3D-Browser tool for OLAP-like operations on the semantic space.

    • Main Results:

    • Successfully built multidimensional semantic spaces from annotated biomedical data.
    • The 3D-Browser tool enables effective exploration and analysis of integrated data.
    • Evaluated the method using the Health-e-Child project data and UMLS Meta-thesaurus.

    Conclusions:

    • Current semantic technologies enable effective integration of biomedical resources.
    • Semantic annotation is key for integrating, exploring, and analyzing biomedical data.
    • The proposed approach is viable and useful for creating high-quality multidimensional semantic spaces.
