Ontology and Taxonomy Examples: Real-World Applications

Ontologies and taxonomies are two powerful tools used to organize and classify various types of knowledge. They are widely used in many industries, from e-commerce to life sciences, and they help companies and institutions extract more value from the data they accumulate.

In this article, we will explore some real-world examples of how ontologies and taxonomies are being used to help people and organizations make better decisions and take more effective actions.

Ontology Examples

Ontologies are formal descriptions of concepts and the relationships between them. In essence, they provide a blueprint for understanding knowledge in a particular domain. Here are some examples of how ontologies are being used in real-world applications:

Pharmaceutical Research

In the field of pharmaceutical research, ontologies are being used to help researchers find new drug targets, understand drug interactions, and analyze patient data. For example, the National Cancer Institute has developed an ontology for cancer research that contains information about genes, pathways, proteins, and drugs.

This ontology allows researchers to search for information about specific cancer types and discover relationships between different genes and proteins. By organizing this information in a structured way, the ontology makes it easier for researchers to understand the complex relationships between different elements and identify new drug targets.

Banking and Finance

Ontologies are also being used in the banking and finance industries to help institutions make more informed decisions about risk management, compliance, and investment strategy. For example, the European Central Bank has created an ontology for financial reporting that standardizes the way financial data is classified and reported across different countries.

This ontology helps regulators and financial institutions identify and analyze risks more effectively, while also making it easier for investors to compare financial data across different companies and markets.


Another area where ontologies are being used is in e-commerce. Online retailers often struggle to organize and classify their product information in a way that is easy to search and understand. By using product ontologies, retailers can classify their products in a more granular way, allowing customers to find what they are looking for more easily.

A great example of this is the e-commerce giant Amazon, which uses ontologies to organize its product information, making it easy for customers to find what they are looking for.

Taxonomy Examples

Taxonomies, on the other hand, are more focused on organizing information into hierarchical categories. Here are some real-world examples of how taxonomies are being used:

Life Sciences

In the field of life sciences, taxonomies are used to categorize and describe the many different species of plants and animals on earth. Taxonomic hierarchies are used to organize organisms into groups based on shared characteristics, making it easier for scientists to identify and classify different species.

For example, the International Union for Conservation of Nature maintains a taxonomy of all the world's species, which is used to help conservationists target their efforts more effectively.

Content Management

Taxonomies are also used in content management systems to help users find the content they need. By organizing content into categories and subcategories, users can quickly navigate to the information they are looking for.

For example, a news website might use a taxonomy to organize its articles by topic or region, making it easy for readers to find news about specific subjects or regions.

Software Development

Taxonomies are also used in software development to organize code libraries and APIs. By organizing code into categories and subcategories, developers can quickly find and use the code they need, saving time and increasing productivity.

For example, the Java programming language has a taxonomy of packages that are used to organize different elements of the language, such as classes,
