Gouvernance Governance Data

Data cataloging companies are increasingly using methods such as ontology, taxonomy, knowledge graph, and thesauri to organize and make sense of the vast amounts of data they process. These methods provide a framework for creating a common vocabulary and structure that can be used to describe and link different data elements, and to discover patterns and insights in the data. In this article, we will first introduce these different methods, then explore the relationships between them and provide examples of their use. Finally, we will highlight the importance of these methods and explain how Dawizz benefits from them and plans to benefit from them in the future.

Ontology : terms, relations, and concepts that are making the buzz in data cataloging

Ontology is a formal definition of a set of terms used to describe and represent a domain. It contains terms and relationships between those terms, as well as property terms that describe the characteristics and attributes of concepts. An example of an ontology is the Gene Ontology (GO), which is used in biological research to describe genes and their functions. GO contains terms such as "cellular component", "molecular function" and "biological process", as well as relationships between these terms, such as "is_one" and "is_part_of".

Taxonomy, or how to bring order to the chaos of data

Taxonomy is the science of classification, used to organize concepts in a hierarchical structure. A taxonomy can be domain-specific or general, and it can be used to classify a variety of things, including organisms, documents, or data elements. An example of a taxonomy is the Dewey Decimal Classification System, which is used to classify books in libraries. The Dewey Decimal Classification System contains broad categories such as "000 - Computer, Information and General Works", which are then divided into subcategories such as "020 - Library and Information Science

Example: How to classify animals

The relationship between ontology, taxonomy and thesauri can be understood through an example in the field of biology. Suppose we build a system that aims to classify and organize different species of animals. First, we can start by creating a taxonomy of animals, which involves grouping animals according to their physical characteristics and evolutionary relationships. For example, we can group mammals, birds, reptiles, fish, and insects into separate categories based on their unique characteristics. This taxonomy provides a basic structure for organizing different species of animals into a hierarchy.

Then, we can create a thesaurus, which can be considered an extension of the taxonomy. The thesaurus allows for more detailed descriptions of each species, including their behavioral traits, habitats, and geographic locations. For example, under the category of mammals, we can include various subcategories such as carnivores, herbivores and omnivores. Each of these subcategories can be further subdivided into more specific groups such as primates, rodents and carnivorous mammals. This allows us to more accurately describe and categorize each animal species.

Finally, we can use an ontology to formally define concepts and relationships in the field of animal species classification. The ontology provides a standardized vocabulary and structure to describe the different concepts and relationships involved, allowing for a more precise and accurate representation of domain knowledge. For example, we can define the term "mammal" as a class with certain characteristics such as hair, milk production, and live birth, and we can define the relationships between different classes such as "carnivorous mammals" and "herbivorous mammals". This allows us to reason more easily and accurately about the field of animal species classification. By using taxonomy, thesaurus and ontology, Dawizz can benefit from a better organization and classification of its data.

The key to efficient and secure data management

Ontologies can be a powerful tool for data and information management, especially in complex environments. By creating formal models of concepts and relationships, ontologies can help organizations identify and organize data more efficiently, improve data analysis and decision making, and ensure compliance with legal and ethical standards. But did you know that ontologies can also be a key tool for improving data security and privacy?

The importance of ontologies in security:

  • By creating ontologies, themes can be identified for sources and servers, which can highlight sensitive sources and provide insight into sensitive servers. By understanding the relationships between these sources and servers, appropriate actions can be taken if necessary.
  • Understanding the interrelationships and connections between entities in a data environment can lead to intelligent exploration and analysis. By using an ontology to map these connections, data analysts can gain insights into complex systems and discover new patterns and relationships.
  • Ontologies can help establish connections between entities and concepts, which can lead to the generation of rules and policies for later verification. By creating rules based on ontological relationships, data management and analysis can become more accurate and efficient.
  • By using ontologies to map the data environment and establish taxonomies, organizations can verify their compliance with regulations such as the GDPR. This can help ensure that data management practices comply with legal and ethical standards, reducing the risk of regulatory penalties and other legal issues.

Ontologies are not just for data management and analysis - they can also play a critical role in improving data security and privacy. By using ontologies to classify and protect sensitive data, identify and mitigate security risks, and ensure compliance with legal and ethical standards, organizations can build more secure and resilient data environments. In short, ontology provides a powerful tool for managing and analyzing data accurately and securely.

Dawizz and the future of data cataloging

Dawizz is an innovative company in the field of data management. Through the use of thesauri, Dawizz can ensure compliance of environments based on general thesauri such as RGPD, or even custom thesauri created and modified by customers. But Dawizz does not stop there. With its research and innovation team, Dawizz is developing a new approach to using ontologies. We know that ontologies can be both an administrator's best friend and worst enemy, as their maintenance is difficult and a small change can cause an avalanche of problems. That's why our team is working on an approach to automatic concept extraction, followed by the creation of taxonomies, thesauri, and then ontologies. This approach will allow our customers to benefit from existing standards and ontologies, but also to automatically create ontologies adapted to their environments and specific needs. With Dawizz, you can be sure that your data is managed efficiently and securely, according to the highest standards. We are always at the forefront of innovation, working on new solutions to facilitate the management of your data.
