The Knowledge Hierarchy is a conceptual framework that outlines the progression of processing raw data to obtain understanding and wisdom. It’s similar to the DIKW Pyramid and the Information Hierarchy, but with a more explicit focus on the levels of knowledge. Here’s a typical breakdown:
Data:
- Definition: Raw, unprocessed facts without context. Data in this stage lacks meaning and might just be a series of numbers, texts, or observations.
- Example: Sensor readings, logs, raw survey results.
Information:
- Definition: Processed data that has been given context and structure. It’s data that has been organized or interpreted in a way that gives it meaning.
- Example: A table showing average monthly temperatures for a city, or a graph showing website visits per day.
Knowledge:
- Definition: Information that has been processed, organized, and structured in a way that it can be used for making decisions, often based on understanding relationships within the information or past experiences.
- Example: Understanding that a dip in website visits correlates with a specific event or time of year based on historical data.
Understanding:
- Definition: An advanced level of knowledge, where there is an appreciation of the “why” behind the information. It encompasses comprehension of patterns, trends, and deeper relationships.
- Example: Recognizing that website visits dip every year during certain holidays and understanding that it’s because the target audience is less active online during these times.
Wisdom:
- Definition: The highest level of the hierarchy, where one can utilize the understanding to make sound judgments, anticipate future trends, or give advice.
- Example: Making a strategic decision to reduce online advertising spend during those specific holidays when website activity dips, reallocating funds to more active periods instead.
The Knowledge Hierarchy showcases the journey from mere data points to actionable insights and decision-making prowess. It’s a helpful model for businesses, educators, and information professionals to understand the value of refining and processing information. As with similar models, the specific naming or number of levels might vary, but the core idea of progressing from raw data to informed decision-making remains.
