Area of Science:

  • Information Science
  • Computer Science
  • Data Visualization

Background:

  • Traditional information retrieval methods struggle with large datasets.
  • End-user manipulation of retrieval sets is often limited.
  • Discovering novel relationships between queries and documents requires advanced tools.

Purpose of the Study:

  • To propose a mathematical framework for organizing and manipulating large information retrieval sets.
  • To develop an interactive data visualization interface for exploring complex data relationships.
  • To enable users to uncover unanticipated connections within retrieval data.

Main Methods:

  • A framework based on mathematical principles for organizing retrieval sets.
  • Parsing retrieval sets into concept-oriented subsets displayed as interactive graphic nodes.

  • Utilizing a vector model for initial distribution of nodes based on query similarity.
  • Designing a user interface for multi-level data exploration and manipulation.

    • Main Results:

    • A visualized information space mapping main concept regions and sub-regions.
    • Interactive graphic nodes representing discrete, concept-oriented subsets of data.
    • The ability for users to adjust weights and relationship types to expose novel connections.
    • Demonstration of a framework facilitating deeper data exploration.

    Conclusions:

    • The proposed framework and visualization interface effectively organize and allow manipulation of large retrieval sets.
    • The system facilitates the discovery of novel and unanticipated relationships between queries and documents.
    • Interactive visualization is a powerful tool for enhancing information retrieval and data exploration.
