Understanding the Information Definition Quote

The question asks to identify the person who defined information based on its relationship to questions starting with "who, what, where, when, and how many." This is a well-known definition in the fields of systems thinking and information science.

Let's look at the options provided:

• Gene Bellinger
• T S Eliot
• Ingetraut Dahlberg
• Ackoff Russel

The quote, "Information is essentially found in answer to questions that begin with such words as who, what, where when, and how many," is attributed to Ackoff Russel. This definition emphasizes information as data that has been processed or given meaning in the context of specific questions, often related to reporting on events or states of affairs.

This quote is often discussed in the context of the DIKW (Data, Information, Knowledge, Wisdom) hierarchy, where Ackoff is a prominent figure associated with defining these levels of understanding. According to this hierarchy, information is the first step above raw data, providing answers to fundamental descriptive questions.

Key Concepts from the Quote

The definition highlights:

• Information is not just raw data.
• Information provides answers to specific types of questions.
• The questions "who, what, where, when, how many" focus on describing events or facts.

Analyzing the Options

• Gene Bellinger: While involved in systems thinking and knowledge, this specific quote is not primarily attributed to him.
• T S Eliot: A famous poet and literary critic, not known for definitions in information science or systems thinking.
• Ingetraut Dahlberg: A significant figure in the field of Knowledge Organization and classification, but this specific definition is not her primary contribution.
• Ackoff Russel: A pioneer in systems thinking, operations research, and management science. This quote about information answering "who, what, where, when, how many" questions is widely attributed to him and aligns with his work on the DIKW hierarchy.

Therefore, based on the attribution of this specific definition of information, Ackoff Russel is the correct answer.

Additional Information: Ackoff's DIKW Hierarchy

Ackoff's work on the DIKW hierarchy provides a framework for understanding the different levels of cognitive content:

• Data: Raw, unprocessed facts, symbols, or observations. Data answers no question.
• Information: Processed data that answers questions starting with "who, what, where, when, and how many". It describes what happened.
• Knowledge: Application of data and information; knowing "how" to do something. It represents knowing what to do.
• Understanding: Appreciation of "why" things happen; involves synthesis and integration of knowledge.
• Wisdom: Evaluated understanding; knowing what is right or wrong, good or bad. It involves knowing what is best.

This hierarchy is a fundamental concept in understanding how data is transformed into higher forms of cognitive value.
