At last month’s Knowledge Graph Conference, in addition to knowledge graphs and graph databases, there is a growing interest in ontologies, but the role of taxonomies does not seem so well understood. For example, in one presentation I attended, it was said “you get synonyms/alternative labels into a knowledge graph…

Hierarchies and Attributes in Taxonomies
One of the challenges in creating hierarchical taxonomies is that there can be multiple ways to categorize concepts and thus design hierarchies. There are multiple methods to deal with this, including polyhierarchy and facets. Now that taxonomies are more often extended with ontologies, attributes can also be used for additional…
Ontologies vs. Knowledge Graphs
A knowledge graph is the instantiation of an ontology, and an ontology is the knowledge model.
Knowledge Graphs and Taxonomies
There is growing interest in and uses of knowledge graphs, which make use of taxonomies.
Taxonomies vs. Ontologies
The question often comes up: how are taxonomies and ontologies different? While there are some short simple answers (such as: taxonomies are hierarchies, and ontologies are semantic networks), it is understandable that the distinction is not that clear. There is considerable overlap. Ontologies may contain taxonomies, and taxonomies can be…
Differing Definitions of Ontologies
In my last blog post I discussed the different definitions and features of thesauri. Now, I will turn to the next kind of knowledge organization system in the spectrum of complexity: ontologies. Actually, to consider an ontology as a more (or most) complex type of controlled vocabulary or knowledge organization…
Knowledge Graphs and Ontologies
I’ve been hearing a lot about knowledge graphs recently. Corporate and academic implementations have been increasing in recent years, and now the taxonomy community is also taking an interest. Taxonomy software vendors are talking about knowledge graphs in webinars, blogs, and conferences, and knowledge graphs was on the list of…
From Taxonomies to Ontologies: Customized and Semantic Relationships
At this year’s Taxonomy Boot Camp conference, I was invited to present on the panel giving 5-minute “Pecha Kucha” lightning talks, for which this year’s theme was ontology. Just as there are different understandings and usages of “taxonomy,” so are there different understandings and usages of “ontology.” You can come…
