Conceptual Frameworks for Knowledge Science Tasks


are analytical constructions for representing summary ideas and organizing information. Knowledge scientists recurrently use such frameworks — knowingly or unknowingly — to derive venture plans, choose machine studying fashions that stability numerous trade-offs, and current findings and suggestions to stakeholders. This text gives an summary of widespread sorts of conceptual frameworks, a easy three-step course of for constructing customized frameworks, and suggestions for efficiently doing so.

Notice: All figures within the following sections have been created by the creator of this text.

Widespread Framework Varieties

Though conceptual frameworks are available in many various sizes and styles, 4 fundamental framework sorts stand out as being particularly widespread in information science initiatives: hierarchies, matrices, course of flows, and relational maps. We’ll briefly go over every of those framework sorts under.

Hierarchies

Hierarchical frameworks usually take the type of tree diagrams, beginning with a root node and ending with a number of leaf nodes, as proven in Determine 1. For instance, the basis node might characterize an overarching idea in a taxonomy or an preliminary binary query in a choice tree. A node’s place within the hierarchy (or tree) provides us invaluable details about its relationship to different nodes. Though Determine 1 labels the gadgets within the hierarchy as “ideas,” they are often any type of entity. Entities could also be impartial (e.g., ideas, matters, segments) or have some constructive or damaging valence (e.g., revenues, prices, issues, points). The hierarchical construction can range in depth and breadth.

Determine 1: Generic Construction of a Hierarchical Framework

In visible representations of hierarchies, vertical hyperlinks between two entities are sometimes drawn explicitly and could be non-directional (easy strains) or directional (downward or upward arrows, relying on the movement of the connection). In contrast, horizontal hyperlinks between entities on the similar degree of a hierarchy are sometimes not proven explicitly. Similar-level entities could also be topic to a pure ordering (e.g., temporal or spatial), which could be proven by putting them accordingly within the framework. As an illustration, entities that happen earlier in an ordering ought to be positioned to the left of entities that happen later. If the entities don’t include a pure ordering, you’ll be able to nonetheless take into account ordering them in a roundabout way (e.g., by degree of significance or precedence) to help reasoning. Entities on the similar degree in a hierarchy ought to usually even be on the similar degree of abstraction.

In lots of conditions, it helps if the nodes of a hierarchy are mutually unique and cumulatively exhaustive, or MECE (pronounced “me-see”), to a big extent. Being mutually unique signifies that the ideas represented by particular person nodes don’t have any main overlaps (i.e., no redundancies), whereas being cumulatively exhaustive signifies that the framework leaves out nothing vital. A MECE hierarchy could be helpful for breaking down a broad idea into sub-concepts (or parts) to establish key drivers of the entire.

Matrices

A matrix is a tabular information construction consisting of n rows and m columns. Knowledge scientists engaged on tabular use circumstances routinely leverage matrices for storing coaching information and mannequin weights. Coaching machine studying fashions can yield high-dimensional matrices of weights that seize advanced relationships between predictors and targets. Low-dimensional matrices just like the one proven in Determine 2 could be helpful for analyzing issues and speaking key insights.

Determine 2: Generic Construction of a Two-by-Two Matrix Framework

The generic two-by-two matrix proven in Determine 2 compares two completely different dimensions in opposition to one another. Such a matrix naturally yields 4 quadrants. By conference, the bottom-left quadrant (the place each dimensions are “low”) is usually the undesirable area of the matrix, and the top-right quadrant (the place each dimensions are “excessive”) represents the fascinating area. For instance, the market analysis agency Gartner makes use of two-by-two matrices to investigate the aggressive panorama in numerous trade sectors and calls the top-right area of the matrix (the place the market leaders are plotted) the “magic quadrant.”

The size of a matrix might characterize steady, ordinal or categorical information sorts. Ideally, these dimensions (or axes) ought to be vital to the overarching framework goal in a roundabout way (e.g., key sub-concepts, issues, or drivers in a given context). The interactions between these dimensions ought to be of specific curiosity as a supply of perception, since it’s these interactions that matrices can seize properly.

Typically, the MECE precept additionally applies to the selection of dimensions — they need to collectively cowl the vital sub-concepts or drivers of the issue being investigated and keep away from redundancies. In any other case, wanting on the interplay might be no completely different from a person dimension. If analyzing the interplay isn’t vital, a hierarchical framework could also be extra appropriate. Changing between a matrix framework and its hierarchical analog could be simple. As an illustration, to rework the matrix in Determine 2 right into a hierarchy, create a root node that defines the general context, let its baby nodes be Dimensions 1 and a couple of, and let their respective baby nodes be “excessive” and “low.”

Course of Flows

A course of movement defines a sequence of logically ordered actions that work together to attain an overarching goal. As an illustration, instruments resembling Dataiku and KNIME enable customers to assemble information science pipelines as course of flows, going from information ingestion all the best way to modeling and report era. Determine 3 depicts a generic course of framework.

Determine 3: Generic Construction of a Course of Framework

The entities of the method in Determine 3 are labeled as actions, however these could possibly be steps, phases, operations, and so forth. The method begins with an exercise (Exercise 1), ends with an exercise (Exercise 3), and has a number of actions in between (Exercise 2). Some inputs are sometimes fed into the method initially and remodeled over the sequence of actions to yield an output. Notice that inputs and outputs also can enter and go away at intermediate steps inside the course of.

As with hierarchies and matrices, the MECE precept could be vital in formulating the completely different actions of the method. If two actions have vital conceptual overlap, you can take into account both grouping them right into a single exercise or breaking them up right into a extra granular set of distinct actions. As an illustration, the intermediate actions in Determine 9 might have resulted from this kind of evaluation; Exercise 2 could possibly be the end result of merging some overlapping actions, whereas Actions 2.1-2.3 could possibly be a granular breakdown of a particular subset of these merged actions. If an exercise or a bigger a part of the method repeats, then it may be represented as a cycle, whereby an exercise transitions to a different exercise that has already occurred earlier than.

The transition from one exercise to a different ought to meaningfully remodel the inputs of the method (e.g., by rising, lowering, combining or in any other case altering the inputs in a roundabout way) with the intention of manufacturing the specified output. If a transition doesn’t change the inputs, then the 2 actions on both facet of the transition are probably redundant and ought to be merged or cut up up in another way, as mentioned above.

Relational Maps

Relational maps shift the main target from particular person ideas (or entities) to the relationships between them. Knowledge scientists working with information graphs or box-and-arrow “path diagrams” of causal relationships (as proven in Determine 4) might be acquainted with this framework sort.

Determine 4: Generic Construction of a Path Diagram

A relationship can usually be any operate that hyperlinks two completely different ideas collectively. 4 sorts of relationships are particularly widespread:

  • Transactional: A relationship can characterize a number of transactions between entities. The transactions might contain the movement of tangible issues (e.g., merchandise purchased and bought) or intangible issues (e.g., info, cash). Transactional relationships can incorporate directionality; a transaction can movement from A to B, from B to A, or in each instructions, and every of those circumstances has a unique that means for the entities (e.g., they might be receivers, senders, or each).
  • Causal: Entities A and B could also be causally associated if A is accountable — not less than partially — for the prevalence or state of B (or vice versa). The character of the causal relationship might range. The position of A is robust if its presence is ample to completely trigger B (though A will not be the one entity that may totally trigger B). The position of A can be robust whether it is essential to trigger B (though A might not be capable to do that alone). Furthermore, if A causes B, it doesn’t essentially observe that B causes A; the notion of directionality is clearly vital for specifying causal relationships.
  • Similarity-based: Entities could also be associated as a result of they’re related or dissimilar in a roundabout way. For instance, entities A and B could be related as a result of they have an inclination to seem in the identical place or occur on the similar time (and dissimilar if the prevalence of 1 entity tends to preclude the prevalence of the opposite). The notion of correlation is a mathematical formalization usually used to assemble measurable, similarity-based relationships. Notice that, simply because two entities are correlated doesn’t essentially imply that they’re causally associated (though if they’re causally associated, then they’d even be correlated).
  • Membership-based: Entities could be linked collectively by being members of the identical group, group, or class. As an illustration, individuals could be associated by being in the identical neighborhood, grocery gadgets could be a part of the identical product class, and a set of sub-concepts could also be a part of an overarching idea. Certainly, one may apply a hierarchical framework to drill down into successively deeper ranges of membership inside entities into account.

How one can Construct Your Personal Frameworks

The next three-step course of can be utilized to construct a customized framework:

  1. Outline the framework’s goal.
  2. Determine the correct constructing blocks (i.e., the framework sort and dimensions).
  3. Put the constructing blocks collectively in an efficient method to reply the framework’s goal.

Step 1: Outline the Goal

In defining the framework’s goal, ask your self: In what context will the framework be used? What ought to the framework accomplish? Can an present framework be reused — maybe with some minor modifications — or does a brand new one have to be constructed to suit your particular wants?

The development of the framework ought to be tied to a better purpose, such because the supply of a venture, formulation of a choice, or creation of some documentation. As soon as the context has been correctly understood, cautious consideration ought to be given to what the framework ought to accomplish in concrete phrases. Is the framework supposed as a decision-making software? Is the framework meant to construction the movement of an argument in a report or a presentation?

Simply since you want a framework doesn’t imply that it’s essential to construct one your self. In lots of conditions, present conceptual frameworks could be reused with out vital modification. Spending some effort to take care of a stable, up-to-date overview of related present frameworks avoids downstream prices of “reinventing the wheel.” Reusing present frameworks has advantages past not having to begin from scratch; if the framework has been round for a while, its important options, in addition to its strengths and limitations, could also be well-documented and examined in numerous settings. Platforms resembling In direction of Knowledge Science are an incredible supply for retaining abreast of conceptual frameworks associated to information science initiatives.

Step 2: Determine the Framework Sort and Dimensions

Having clarified the target of the framework, it’s time to suppose extra concretely concerning the development of the framework itself. One of many important difficulties right here is that conceptual frameworks are inherently not as tangible as bodily ones (like molds in a manufacturing facility). We are likely to intuit the hyperlink between kind and performance — the framework and its objective — extra simply when the framework and its object are tangible. The hallmark of conceptual framework is its capacity to show a seemingly intangible argument or resolution into one thing extra tangible, and the important thing to that is illustration.

Broadly talking, there are two elements that decide the illustration of conceptual frameworks: the sort of the framework and the dimensions of the framework. You’re prone to discover the framework sort first because it determines how the framework seems as a complete. The earlier sections coated the 4 widespread framework sorts. The framework dimensions dictate what the framework can particularly characterize (e.g., by way of granularity and ordering). By adjusting the size, the identical framework sort could be reused to generate a variety of various insights. Following are three widespread lessons of framework dimensions:

  • Categorical: These dimensions encompass a finite set of discrete classes that totally describe the dimension. The classes needn’t be ordered (e.g., a set of merchandise, buyer segments, gender).
  • Ordinal: These dimensions are ordered, which implies that you would be able to analyze whether or not one thing is “lower than,” “better than,” “equal to,” and so forth, in relation to one thing else (e.g., damaging/constructive, low/medium/excessive).
  • Steady: Such dimensions can take the notion of ordinal dimensions to a way more granular degree. Being steady signifies that the dimension is numerical and might embrace decimals (e.g., 1.23, -2.718, 3.14159).

Step 3: Put It All Collectively

As soon as the framework sort and dimensions have been recognized, they are often mixed to supply a customized framework. Typically, the identification and mixture steps aren’t explicitly separated, because you not often do one with out the opposite. However the framework sort and its dimensions — the essential constructing blocks — aren’t essentially wedded to one another. Some combos might make extra sense than others, and you’ll usually combine and match the constructing blocks in some ways, over a number of iterations, till the framework feels proper. Be capable of spot and exploit this combinatorial flexibility is a vital talent that you must begin creating from the outset of your framework-building journey.

Furthermore, there are broadly 4 “pathways of research” that seize the hyperlink between the framework and its goal:

  • Descriptive: Approaches the framework’s goal by gathering and organizing previous info (e.g., utilizing visuals resembling graphs and tables, or written summaries). Doing so permits us to higher describe and analyze what occurred previously, however it might not essentially inform us why one thing occurred, or whether or not it’ll occur once more.
  • Diagnostic: Takes descriptive info of previous occasions and goes a step additional to take a look at why one thing occurred. That is accomplished by drilling down into the information, mining for clues and correlations, and looking for a believable hyperlink between trigger and impact. As with the descriptive pathway, the main target is on the previous.
  • Predictive: Differs from the prior two by asking and answering questions concerning the future. The main focus is on making an informed guess about what’s going to occur sooner or later by counting on a bunch of sometimes quantitative strategies that vary from the easy (e.g., fundamental chance idea, linear fashions) to the extra advanced (e.g., neural nets).
  • Prescriptive: Goes past merely predicting future occasions to recommending methods to cope with them. The main focus is on determining the best way to make one thing occur — or whether or not it ought to occur — sooner or later. The reasoning for the prescription could be quantitative (e.g., based mostly on statistics or simulation modeling) or qualitative (e.g., based mostly on private expertise).

Framework sorts and dimensions can due to this fact be mixed in numerous methods to supply customized frameworks that lend themselves to descriptive, diagnostic, predictive, and prescriptive use circumstances.

High Ideas

This part provides 5 suggestions for constructing good conceptual frameworks. The information are certainly not an exhaustive record of the factors that you must take into account, however characterize a fundamental set of issues to remember.

Tip 1: Concentrate on the Goal and Viewers

The method of constructing frameworks broadly consists of three steps, particularly defining the target, then figuring out and mixing the constructing blocks (framework sorts and dimensions) accordingly. Whereas step one will, by its nature, emphasize the strategic goal and target market of the framework, the main target within the latter two steps shifts to the nitty-gritty particulars of the framework’s constructing blocks. The deeper you get into the mechanics of the framework, the more durable it may be to take care of visibility of the unique goal. To keep up visibility of the larger image, it could assist to take a step again once in a while through the framework-building course of and remind your self of the strategic goal and target market. It could additionally assist to delay a part of the evaluation till the required information turns into accessible and to hunt common suggestions from colleagues and the target market of your framework the place potential.

Tip 2: Preserve It as Easy as Doable

To paraphrase a quote usually attributed to Albert Einstein — one of the vital completed builders of conceptual frameworks of the final century — we will say {that a} framework ought to be made so simple as potential, however not less complicated. Because the course of inherently includes attempting out completely different combos of framework sorts and dimensions, it could typically be tempting to snap an increasing number of items collectively. But sacrificing simplicity can doubtlessly diminish the broader worth of the framework in follow. Complicated frameworks could be obscure, apply, consider, and construct — you might have to confirm a number of assumptions and preconditions, and regulate many various levers inside the framework.

Tip 3: Make It MECE 

Making certain {that a} framework is MECE has some vital benefits. From a theoretical standpoint, being MECE signifies that the sub-concepts observe a constant, additive part-whole logic; you count on the sub-concepts to “add up” to kind the larger idea. Crucially, this logic means that you can substitute the set of sub-concepts for the larger idea (and vice versa) all through your evaluation. The additive logic of MECE additionally allows you to examine completely different ideas in a rigorous method; as a substitute of claiming that two ideas are related, you’ll be able to state exactly the extent to which they’re related by figuring out the sub-concepts they share. From a sensible perspective, being MECE means that you would be able to “divide and conquer” large issues effectively and options to some sub-problems could also be reusable. Typically you’ll be able to even attain the answer of the larger drawback with out fixing all of the sub-problems (e.g., if the larger drawback could be represented as a disjunction of the sub-problems). Bypassing sub-problems additionally works if you end up fixing the larger drawback inductively (e.g., as in mathematical induction).

Tip 4: Make It Versatile 

Essentially, a conceptual framework ought to be designed to fulfill its general goal, so you might be questioning why flexibility is a crucial facet to think about. In follow, there are not less than two sorts of conditions by which flexibility could be a large assist. Within the first state of affairs, you might be coping with an goal that may be a transferring goal, with some components of the target’s full scope altering (even barely) once in a while; responding to such scope adjustments could be a ache if some flexibility isn’t baked into the framework. Within the second state of affairs, your framework might need to bear a number of iterations, by which completely different framework sorts and dimensions are added, modified and eliminated over the course of the framework’s evolution; a versatile design makes it a lot simpler to facilitate such alterations of the framework’s form and content material. Modularity, scalability, robustness, extensibility, and portability — whereas sometimes related to software program engineering and structure — are additionally related design concerns for constructing versatile conceptual frameworks.

Tip 5: Construct It Iteratively 

It might be nice in the event you may provide you with the right framework in a single go, however it not often works out that means. A number of components could make the primary iteration extra of a primary draft, to be adopted by not less than a number of extra. The overarching goal — and particularly the operational implications in terms of constructing the framework — will not be totally clear at first. Over a few iterations, nonetheless, you’ll most likely start to get the hold of which framework sorts and dimensions work and which don’t. Whereas your output after a given iteration could also be removed from excellent, it may nonetheless quantity to a minimal viable product (MVP) if it yields a viable answer to the overarching goal with minimal effort and complexity. The MVP could be examined (e.g., with precise information and actual customers) to know its strengths and weaknesses. Every successive iteration can produce an improved MVP by including, eradicating or altering options of the earlier iteration.

To shut off, here’s a video that shares some extra good recommendation on constructing and utilizing conceptual frameworks:

The Wrap

Conceptual frameworks assist us flip summary concepts into concrete, tangible merchandise that different individuals can see, use, and recognize. This may be particularly vital for information scientists, or so-called “information employees,” whose jobs contain gathering, analyzing, and deriving conclusions from information. If you’re studying this text, you’re most likely a information employee. To paraphrase well-known administration guru Peter Drucker, “It’s information that permits information employees to do their job,” however it’s the capacity to meaningfully arrange this information that results in a job properly accomplished — and that, in a nutshell, is why the right use of conceptual frameworks can assist the profitable design and supply of information science initiatives.
