It’s an interesting paper as Jennifer revisits the DIKW hierarchy, a.k.a. ‘data-information-knowledge-wisdom hierarchy’, ‘Knowledge Hierarchy’, ‘Information Hierarchy’ and, almost done, ‘Knowledge Pyramid’. Given the many names it received you can imagine the DKIW Pyramid has always been very popular in the broader space of information management – and beyond. And with Industry 4.0, IoT and AI/ML the decisions/actions can also be (semi-)autonomous, although everything depends on the nature and purpose of the data. Knowledge is the (1) cognition or recognition (know-what), (2)
capacity to act (know-how), and (3) understanding (know-why) that resides or is
contained within the mind or in the brain.

is data put in context; it is related to other pieces of data. If knowledge is power, then democratic knowledge-driven societies should be able to make great strides in lessening inequality. If you want to know why, read Haggart and Tusikov’s The New Knowledge. With a clarity of prose to savor, Haggart and Tusikov explain how exclusivity and asymmetry of knowledge are leading us into an inequality most of us do not want.
Actioning Knowledge Graph
Sometimes we mean know-how, while other times we are talking about wisdom. Part of the difficulty of defining knowledge arises from its relationship to two other concepts, namely data and information. These terms are often considered as lower denominations of knowledge, but the exact relationship varies from one example to another. To talk about the concept of knowledge management (KM), one must start by clearly defining the meaning of the words “knowledge”, “data” and “information”. We often hear the terms data, information, and knowledge tossed around.
(While “datum” is technically the singular form of “data,” it’s not commonly used in everyday language.) Data can come in the form of text, observations, figures, images, numbers, graphs, or symbols. For example, data might include individual prices, weights, addresses, ages, names, temperatures, dates, Knowledge Information Data or distances. And solving data management and information management challenges these days looks far more complex with the proliferation of data sources and types. Nevertheless, the DIKW model is still used in many forms and shapes to look at the extraction of value and meaning of data and information.
Challenges of data literacy
The pathway maps similar to Figure 3 are now made available under the category of metabolism overview maps (map numbers 01200s). In contrast to the previously developed global maps (map numbers 01100s), which omit intermediate reaction steps, the overview maps contain all the reaction steps as in the regular KEGG metabolic pathway maps. In addition, they are manually annotated with KEGG modules and reaction modules. These maps represent our efforts to present design principles of the metabolic network rather than traditional views of individual pathways. It is an extensive use of the same paths with minor modifications (2), such as reductive pentose phosphate pathway that contains two key reaction steps catalyzed by RuBisCO and PRK. The overview maps, together with KEGG modules and reaction modules, will be expanded toward understanding basic principles of metabolic networks.
- Synthesising insights from Susan Strange, Robert Cox, and Karl Polyani, Haggart and Tusikov offer a scathing and brilliant analysis.
- It is important to remember that knowledge has different meanings depending on the discipline where it is used.
- Connect and contextualize the variety of structures and formats of your data so you can operate more efficiently and effectively.
- You can see more variations of DIKW in our article ‘From data to value‘; there’s even a big data DIKW model.
- I will discuss this in the section titled “The Different Kinds of Knowledge”.
- In the context of business, the purpose of knowledge is to
create or increase value for the enterprise and all its stakeholders.
Depending on this purpose, data processing can involve different operations such as combining different sets of data (aggregation), ensuring that the collected data is relevant and accurate (validation), etc. For example, we can organize our data in a way that exposes relationships between various seemingly disparate and disconnected data points. More specifically, we can analyze the Dow Jones index performance by creating a graph of data points for a particular period of time, based on the data at each day’s closing. To take advantage of the insights they own, organizations need the right IT solutions and expertise to create data management frameworks to organize R&D data. One common challenge faced is harmonizing scientific terminology across information sources.
Knowledge as propositional
The need of data mining is to extract useful information from large datasets and use it to make predictions or better decision-making. Nowadays, data mining is used in almost all places where a large amount of data is stored and processed. Of course, not everyone is in an organization trying to build a culture of data literacy.
The flow from data to information and knowledge is not uni-directional. The knowledge gained may reveal redundancies or gaps in the data collected. As a result, an actionable insight may be to change the data collected, or how those data are converted into information, to better meet user needs. The flow and characteristics of these terms are illustrated in Figure 1 and Table 1. Table 2 provides examples of data, information, and knowledge for water data.
