This study presents a novel XML markup method for medical texts, overcoming traditional nesting limitations. The new approach integrates semantic structure with text linearity, improving data interchange for NLP applications.

Area of Science:

  • Computer Science
  • Bioinformatics
  • Natural Language Processing

Background:

  • Extensible Markup Language (XML) is crucial for data interchange but its tree-like structure struggles with non-nested text features.
  • Marking up medical texts with semantic information from Natural Language Processing (NLP) highlights XML's nesting limitations.
  • Existing solutions often separate structured data from text markup, hindering integrated analysis.

Purpose of the Study:

  • To develop an alternative XML markup solution for medical texts that overcomes traditional nesting restrictions.
  • To integrate semantic structures directly with the text's linear representation.
  • To enhance the utility of XML for representing complex medical text data.

Main Methods:

  • Developed a novel XML markup strategy that preserves the inherent linearity of medical texts.

  • Integrated structured semantic information directly within the XML markup.
  • Ensured that the markup accommodates features that do not conform to strict hierarchical nesting.

    • Main Results:

    • The proposed XML markup successfully preserves text linearity, unlike traditional tree-based structures.
    • Semantic information is tightly integrated with the text, enabling a more cohesive representation.
    • The method allows for straightforward expansion with additional data types.

    Conclusions:

    • The novel XML markup approach offers a more effective way to represent medical texts with complex semantic structures.
    • This method enhances data interchange capabilities for NLP and bioinformatics applications.
    • The integrated approach facilitates easier expansion and utilization of medical text data.
