Knowledge Discovery: The “Concepts — Notions” Mapping
A typology of concepts and concept curation
This article is part of the Slow Cognition Project which focuses on Developing Tacit Knowledge with Thematic Space Canvas. The Knowledge Discovery Canvas is an application of the Thematic Space Canvas.
The Knowledge Discovery Canvas has two nested squares which divide the thematic space into two sub-spaces: inner space and outer space. For Developing Tacit Knowledge, the inner space is all about personal knowing activities while the outer space is related to social interactions.

Based on the above settings, I generated a series of mapping between outer space and inner space:
- Approaches — Tastes
- Concepts — Notions
- Events — Projects
- Domains — Works
- Perspectives — Views
- Frameworks — Insights
- Methods — Guides
- Heuristics — Skills
Today I’ll focus on the Concepts — Notions mapping and develop a typology of concepts.
In April 2021, I wrote a book called The ECHO Way to reflect on the process of writing three books. In the book, I used one chapter to discuss the topic of Concept Curation. This article will also share some ideas from the chapter.

Part 1: A Typology of Concepts
Part 1 aims to develop a new typology of Concepts for the Knowledge Discovery Activity.
1.1 Theory, Practice, and Concepts
The Knowledge Discovery Canvas is designed with four areas: the THEORY area, the PRACTICE area, the END area, and the MEANS area. The “Concepts — Notions” mapping is located in the THEORY area.
Originally, I only considered Theoretical Concepts for the Knowledge Discovery Canvas. Inspired by the MEANS — END spectrum for Frameworks, I developed the following “Theory — Practice spectrum” for Concepts. The outcome is a new typology of Concepts.

The above diagram shows six types of concepts which are divided into two groups.
The first group is related to the “THEORY” area and these concepts are about research and producing new public knowledge.
- Theoretical Concepts
- Operational Concepts
- Orienting Concepts
The second group is related to the “PRACTICE” area and these concepts are about learning, sharing, and working with knowledge for individual purposes.
- Technological Concepts
- Sociocultural Concepts
- Shared Concepts
The distinction between the “THEORY” group and the “PRACTICE” group considers the two types of motivations for dealing with concepts. One is for contributing to the development of public knowledge, the other one is for using public knowledge for private purposes. These two types of motivations lead to different attitudes toward appreciating concepts.
1.2 Theoretical Concepts and Operational Concepts
Theoretical Concepts are the foundation of theoretical approaches such as Meta-theories and Specific Theories. They can be used to develop knowledge frameworks.

For example, the above picture is a screenshot of the homepage of Activity Analysis which is a website for sharing knowledge about Activity Theory and other social practice theories. The category of “Concepts” only publishes articles about individual concepts. For Activity Theory, “Activity”, “Object”, “Mediation”, and “Hierarchy of human activity” are primary theoretical concepts.
Operational Concepts are developed for empirical research and reflection. It can be generated from theoretical concepts or not. I use the distinction between Abstract Models and Concrete Models to emphasize the relationship between Theoretical Concepts and Knowledge Frameworks. If a framework incorporates some Theoretical Concepts, then it is an Abstract Model. If a framework only uses Operational Concepts without adopting any Theoretical Concepts, then it is a Concrete Model.
Some knowledge frameworks can directly adopt some theoretical concepts as their operational concepts. For example, Yrjö Engeström’s Activity System Model is a knowledge framework. Its diagram displays seven operational concepts.

We should notice that a knowledge framework can directly adopt some theoretical concepts as its operational concepts. For example, the above diagram shows “Subject” and “Object” which are core theoretical concepts of Activity Theory. However, some researchers use “Actor” to replace “Subject” with the same diagram for their own work. The concept of “Actor” should be understood as an operational concept. For real-life research, the difference between “Subject” and “Actor” doesn’t matter since we need to see the final data which refers to a person or several people.
While Yrjö Engeström uses the word “Instruments”, other researchers use “Mediating Tool” or similar words. For example, Maral Babapour, Antonio Cobaleda-Cordero, and Marianne Karlsson adopt Activity Theory to develop a framework for understanding the interrelations between users and workplace design. They use the word “Mediating Tool”.

Both theoretical concepts and operational concepts can be defined precisely or vaguely. For example, the scope of the concept of “Instruments/Mediating Tool” is very broad in Activity Theory. The above diagram shows an example, the authors understand “Office Environment” as a “Mediating Tool” from the perspective of Activity Theory. Since Activity Theory doesn’t have a theoretical concept of “Environment,” researchers tend to use the concept of “Instruments/Mediating Tool” to understand “Environment”.
We also should notice that a knowledge framework’s diagram may not display some key theoretical concepts. In fact, we don’t have to display theoretical concepts in a diagram because we can discuss them with words in a research report. For example, the concept of “Mediation” is a foundational theoretical concept of Activity Theory. In fact, Yrjö Engeström’s Activity System Model was developed with double mediations. However, the Activity System Model doesn’t display the word “Mediation” in its diagram.
1.3 Orienting Concepts and Intermediate Concepts
Both Orienting Concepts and Intermediate Concepts are only useful for knowledge creators. The term “Orienting Concepts” is coined by the sociologist and social theorist Derek Layder.
Derek Layder suggests using Orienting Concepts as the starting point to guide research, “Two important features of orienting concepts are their ‘two-sided’ nature and their reference to social processes. The Two-sided nature of orienting concepts concerns their dual reference to objective and subjective aspects of social life. A concern with social processes focuses on their ability to trace social activity and events over time and space.” (1998, p.101)
A great example of orienting concepts is “Career”, Layder pointed out, “The twin virtues of the concept of career stem from its theoretical relevance and the breadth of its empirical applicability. The empirical scope of the concept derives from its use outside as well as inside the context of work and occupations…the concept of career is potentially capable of addressing certain problems in social analysis. In particular, it could help to overcome certain divisions such as that between macro and micro analysis and between interpretive and institutional analysis (‘interactionist’ or ‘structural’ sociology). This is because, as I have said, the concept of career is capable of reaching into both objective and subjective aspects of social life. In these senses, the concept uniquely expresses the intertwining of individual experience and the collective forces that constitute what we generally mean by the term ‘society’. Thus, career is a step towards overcoming the false distinction implicit in the old argument about the ‘individual versus society’.”(1993, pp.131–132)
In 2020, I followed Layder’s suggestion and used “Project” as an Orienting Concept for the book Project-oriented Activity Theory.
I also use “Intermediate Concepts” for developing new ideas. You can find more details in Knowledge Discovery: The “Middleware” Strategy. I don’t add “Intermediate Concepts” into the above typology because it only refers to a specific strategy.
1.4 Technological Concepts and Sociocultural Concepts
The distinction between Technological Concepts and Sociocultural Concepts was made in the Concept-fit framework for Platform Innovation.

I classify such terms as Sociocultural Concepts because they refer to social behaviors and social phenomena. The value of Sociocultural Concepts is for ordinary communication and professional practices. By sharing such terms, we can exchange our insights on emerging social needs and changes in society.
By contrast, Technological Concepts refer to scientific theoretical knowledge and operational techniques. For example, “Search Engine,” “Ubiquitous Computing,” “5G,” “Virtual Reality,” “Blockchain,” “Responsive Web Design,” and “Markdown”. The value of Technological Concepts is for scientific discovery, academic research, and their industrial applications. It helps scientists, theorists, researchers, engineers, teachers, and designers on producing new knowledge and transform abstract knowledge into concrete practice.
It’s hard to make a simple and accurate typology. My goal is to distinguish Concepts into Sociocultural types and Technological types. The above definitions may not be accurate, however, the distinction is already described by the terms “sociocultural” and “technological”. In fact, some concepts are both sociocultural concepts and technological concepts. For instance, “SEO,” “Blog,” “Social Media,” “Open Access,” “MOOC,” etc. In order to keep a simple starting point, let’s remain this rough distinction.
I also developed sub-categories of Technological Concepts and Sociocultural Concepts for the Concept-fit framework. You can find more details here.
1.5 Shared Concepts and Personal Notions
While Technological Concepts and Sociocultural Concepts focus on public knowledge for learning and use, the term “Shared Concepts” and “Personal Notions” consider the social contexts of using these concepts.
Shared Concepts refer to personal communication contexts, team working environments, community discussions, social media discussions, non-academic public events, etc.
The issue of “Shared Concepts” leads to the challenge of balancing academic knowledge and practical situations. Let’s look at two examples, the first one is humor I found in Daniel Newman’s tweets.

Obviously, we know this is a joke about language and daily communication. Human communication is highly contextualized, if a person doesn’t pay attention to the background of the conversation, he won’t get a great benefit from talking with others.
The second one is a litter harder than the above humor. The TEDx talk below is about “Comfort Zone”. Does the speaker use the concept as a normal word or an academic concept? Not all TEDx/TED ideas are worth spreading. Sometimes, we need to press the pause button and keep the idea for tweaking for a while.
