How are taxonomies related to “semantics”? I considered this question, as the latest conference I participated was SEMANTiCS, the European conference of semantic technologies, which took place this year in Vienna, Austria, September 13 – 15. Topics presented and discussed in this conference included ontologies, knowledge graphs, semantic models and…

SKOS-XL for Taxonomies
I recently posted about SKOS (Simple Knowledge Organization System). If you have read anything about SKOS, then you might have come across SKOS-XL (SKOS Extension for Labels) and wondered what that is. The World Wide Web Consortium (W3C) released its recommendations for SKOS and SKOS-XL at the same time in 2009…
Taxonomy Challenges Discussed at SLA Conference
When it comes to conferences dealing with the subject of taxonomy creation, implementation, and maintenance, without a doubt Taxonomy Boot Camp and Taxonomy Boot Camp London are by far the best conferences for their content, speakers, and networking opportunities. However, there are other conferences that have sessions on taxonomies. The…
SKOS Taxonomies
Over the 26 years that I have been involved in controlled vocabularies, thesauri, and taxonomies, the biggest change I have seen in the field is the adoption of SKOS (Simple Knowledge Organization System) as a schema model and standard. If you are creating taxonomies exclusively within a single system (such…
A Taxonomist Community
Taxonomists and others whose work involves taxonomies have not been a unified professional community. Taxonomy development work is interdisciplinary, spanning different specializations, and different organizational functions, including the following: Information services taxonomies and thesauri, developed by those with a background in library/information science, thesauri, and cataloging, and possibly indexing Product/ecommerce…
Polyhierarchy in Taxonomies
A defining characteristic of taxonomies is that terms/concepts are arranged in broader-narrower hierarchies, which may resemble tree structures. A limited number of top concepts each have narrower concepts, which in turn may have narrower concepts, etc., and the narrowest concepts at the bottom of the hierarchy are sometimes referred to…
Taxonomy Quotes
Taxonomies are very valuable, but not always easy to define, and they are described in various ways. They are also interdisciplinary, as taxonomies are developed by people in different fields for slightly different, yet similar purposes. I have heard various comments about taxonomies over the decades. In the earlier years…
Defining a Taxonomy’s Scope
In planning a taxonomy, I have often said that it is important to define the taxonomy’s scope, specifically the subject area scope of the taxonomy’s terms, but without going into more detail. Recently I was asked by a client how to define a taxonomy’s scope. This is a good question.…
Taxonomist Survey
In keeping with the title of this blog, it’s time to check in again to learn more about who taxonomists are and what they are doing. I conducted a survey of taxonomists (promoted through discussion lists, groups, and social media) in 2009 to gather information for my book, The Accidental…
Named Entities in Taxonomies
I have long felt that there is some uncertainty as to where named entities (names of specific people, places, organizations, products, etc.) fit into taxonomies. Standards suggest one way, and practice tends to follow different way in dealing with these proper nouns. As taxonomy trends evolve so does the position…
