Conceptualization

Conceptualization is the process of identifying, abstracting, and organizing a coherent set of concepts and relationships that represent the essential important elements, relationships, and possible states of affairs within a given subject domain (a.k.a. area of knowledge, field, universe of discourse). It transforms the complexity of reality into structured ideas that can be shared, discussed, analyzed, and modeled.

A conceptualization is intended to be understandable by humans (the community of subject domain stakeholders) but can also be represented in machine interpretable form. Conceptualizations are social artifacts, sociotechnical tools.

A conceptualization serves as a shared understanding among domain stakeholders, enabling them to articulate and reason about the subject domain in consistent, meaningful, and useful ways. It captures not only what exists, but also what could possibly exist by defining the admissible configurations, constraints, mechanics, and dynamics of that subject domain.

Conceptualization is the foundation for formal modeling, providing the semantic scaffolding for defining entities, properties, qualities, traits, relationships, and governing rules.

A conceptualization is the bridge between raw data and structured understanding. It bridges raw data and structured knowledge, enabling interoperability, clarity, and precision across systems and contexts. Conceptualization is the act of turning what might be a messy reality into clear ideas. A conceptualization can be used to understand all possible states of affairs which might be possible and admissible within a subject domain.

To be effective, a conceptualization should be:

  • Community-driven: Established through consensus among domain subject matter experts and other stakeholders.
  • Formally represented: Encoded in a conceptual model using an appropriate modeling language (e.g., OWL, SHACL, RDF, UML, XBRL) to serve as a durable digital sociotechnical artifact.
  • Purposeful: Designed to adequately support reasoning, communication, system design, and problem-solving within the given subject domain.
  • Governance: Governance is the framework for setting of boundaries of acceptable conduct and practices of stakeholders related to the creation and ongoing curation of a conceptualization.
  • Upper-ontology: A conceptualization should be based on an upper or top level ontology to maximize interoperability with other conceptualizations of other subject domains.

Ultimately, conceptualization empowers us to make sense of complexity, communicate with rigor, build interoperable systems, and construct theories that reflect both the structure and nuance of the real world.

Conceptualization is process of forming abstract ideas and identifying key concepts and relationships. A conceptual framework is a high-level structured representation of key concepts and theories tailored to guide analysis or design.  A conceptual model is a more formalized representation of specific concepts and relationships which can then be used by automated simulation, analysis, or implementations of the conceptualization.

A conceptualization forms a specification.  A good conceptualization creates a virtuous cycle.  A conceptualization should be 
  • clear, uses as few words as possible (i.e. not redundant), 
  • consistent (as contrast to inconsistent), 
  • complete (as contrast to incomplete), 
  • sound and meaningful (as contrast to unsound), and 
  • precisely and accurately represent the subject domain (as contrast to incorrect, imprecise, and inaccurate).

Overview

Imagine it.  Freedom from drudgery. Freedom from the toil of tedious, repetitive, mundane, monotonous tasks. This overview is an attempt to take the work that I have done to understand XBRL-based reports and back into a framework for explaining those reports to accountants and software engineers building software for accountants.  I am not referring to this as model-driven reporting .   The sources of the information provided below are my " lab notebook " from December 2007 to October 2022; my Digital Financial Reporting blog from October 2022 until January 2025; Mastering XBRL-based Digital Financial Reporting ; and finally my Seattle Method  documentation. What I have tried to do is take the seemingly hundreds of incomplete, far too technical, typically nonstandard explanations that I have come across; take the good/best ideas from each, make improvements to those explanations, and resynthesize the information into a form that is useful to me and perhaps usef...

Knowledge Representation Approach

Image
Knowledge representation is simply organizing knowledge related to some area of knowledge into some physical form.  A knowledge representation provides an explanation of or description of the nature and structure of something. There are a number of different approaches that a knowledge representation might take, each approach having a different level of expressivity and reasoning capability.  These different knowledge representation approaches form a spectrum.  The following is a graphic which shows the expressivity and reasoning capability of different knowledge representation approaches: The following is a brief description of each of the different knowledge representation approaches which will help you understand the relative expressivity and reasoning capability of each approach: Name authority : A name authority provides what amounts to a dictionary or list which amounts to a flat inventory of terms with no relations expressed between the terms. This can be thought...

Area of Knowledge

Image
An area of knowledge (a.k.a. area of interest, field, domain, subject domain, universe of discourse) is a highly organized socially constructed aggregation of shared knowledge (a.k.a. corpus) for a distinct subject matter.  Subject matter experts (SMEs) create, use, and maintain an area of knowledge. An area of knowledge has a specialized insider vocabulary, underlying assumptions (axioms, theorems, constraints, assertions, restrictions), and persistent open questions that have not necessarily been resolved (i.e. flexibility is necessary).  You can think about an area of knowledge as being characterized in a spectrum with two extremes: Kind area of knowledge: clear rules, lots of patterns, lots of rules, repetitive patterns, and unchanging tasks. Wicked area of knowledge: obscure data, few or no rules, constant change, and abstract ideas. Stakeholders of a system need to be in agreement as to an undisputed core knowledge of an area of knowledge. Sensemaking is the process of d...
