It involves encoding information in a way that it can be easily understood, processed, and utilised by people.

This field spans multiple disciplines,

  • including artificial intelligence,
  • cognitive science,
  • Linguistics, and
  • psychology.
  1. Natural Language:

    • Text and Speech: Using written and spoken language to convey information. This includes books, articles, conversations, and digital content.
  2. Visual Representation:

    • Diagrams and Charts: Tools like flowcharts, bar graphs, pie charts, and mind maps to visually organize and represent data and concepts.
    • Infographics: Combining visuals and minimal text to present complex information quickly and clearly.
    • Maps: Geographic or conceptual maps to represent spatial or relational information.
  3. Structured Data:

    • Tables and Spreadsheets: Organized rows and columns to structure data for easy access and manipulation.
    • Databases: Structured collections of data stored in a way that can be efficiently retrieved and managed (e.g., SQL databases).
  4. Hierarchical Representation:

    • Taxonomies: Classifying information into hierarchical categories and subcategories (e.g., biological classification systems).
    • Ontologies: Formal representations of knowledge within a domain, defining entities, relationships, and rules (e.g., semantic web technologies).
  5. Conceptual Models:

    • Concept Maps: Visual tools that show relationships between concepts, often used in education and knowledge management.
    • Entity-Relationship Diagrams (ERDs): Used to model data and their relationships within a system.
  6. Logical and Formal Representations:

    • Propositional and Predicate Logic: Mathematical representations of statements and their relationships, used in formal reasoning and AI.
    • Rules and Constraints: Specifying conditions and rules for data and processes (e.g., business rules in enterprise systems).
  7. Multimodal Representations:

    • Combining Multiple Forms: Using a mix of text, visuals, audio, and interactive elements to convey information, such as in multimedia presentations or e-learning platforms.
