This study introduces the Expository Text Analysis Tool (ETAT), a software solution designed to rapidly and objectively analyze the coherence of expository texts using conceptual graph structures.

Area of Science:

  • Natural Language Processing
  • Computational Linguistics
  • Text Analysis

Background:

  • Qualitative analysis of expository text coherence is time-intensive.
  • Challenges exist in ensuring coding reliability with manual methods.
  • Objective and efficient text analysis tools are needed.

Purpose of the Study:

  • To introduce the Expository Text Analysis Tool (ETAT) for automated text coherence analysis.
  • To provide a more objective and rapid method for evaluating expository texts.
  • To leverage conceptual graph structures for text representation.

Main Methods:

  • ETAT segments texts into nodes.
  • Unidentified nodes are classified.
  • Nodes are linked using relational arcs to form conceptual graphs.

Related Experiment Videos

  • The software is developed in Java for broad compatibility.

    • Main Results:

    • ETAT automates the construction of text coherence graphs.
    • The tool generates statistics on node interrelationships.
    • Information on isolated or non-interrelated nodes is provided.
    • The software offers a high level of objectivity in analysis.

    Conclusions:

    • ETAT offers a significant improvement over traditional qualitative methods for text coherence analysis.
    • The tool enhances objectivity and speed in evaluating expository texts.
    • Conceptual graph structures provide a robust framework for automated text analysis.
