Creating a Taxonomy

Prompt

Before we generate a knowledge graph it is useful to group similar types of concepts together and then assign them a color. This allows you to seen patterns of similar items in the learning graphs. Note that we are not concerned with learning order. We only want to put similar types of concepts near each other in a taxonomy.

Prompt

Next, let's Create a taxonomy to classify these concepts. For the list of concepts, can you suggest a taxonomy of up to ten categories on how to classify each concept? For example: 1. Foundational Concepts (Mathematical Foundations), 2. Types of Signals. 3. Fourier Transforms ... 10. Miscellaneous

For each of the categories create a category label and list the concepts under that category.

  • 8. Machine Learning and Neural Networks in Signal Processing
  • 9. Applications in Communications and Multimedia
  • 10. Emerging and Specialized Topics

• Each concept from the original list is assigned to one of these categories based on the taxonomy provided earlier.

• The CSV file includes:

  • ID: The concept ID from the original list (1 to 150).
  • Concept Name: The name of the concept.
  • Dependencies: A pipe-delimited list of IDs of concepts it depends on.
  • Category ID: The category number (1 to 10) to which the concept belongs.

  • Notes:

  • The concepts are uniquely assigned to one category to avoid duplication.

  • Foundational concepts without dependencies have an empty Dependencies field.
  • All concepts are connected to at least one other concept through dependencies or category grouping.

How to Use This CSV File:

• Teaching Order Determination:

  • By examining the dependencies, educators can determine the prerequisite concepts needed before introducing a new topic.
  • The category IDs help structure the course into modules or sections.

  • Visualization:

  • The CSV file can be used to create a network graph where nodes represent concepts, edges represent dependencies, and colors or groupings represent categories.

  • Curriculum Development:

  • The taxonomy and dependencies assist in curriculum planning, ensuring that foundational topics are covered before advanced concepts.

Assumptions Made:

• Dependencies:

  • Dependencies are based on logical prerequisite knowledge required to understand a concept.
  • If a concept depends on multiple concepts, their IDs are separated by a pipe (|).

  • Category Assignment:

  • Each concept is placed in the category that best fits its primary focus, as per the taxonomy provided.
