Re: When to use has_broader_match?

Hi Michael and welcome in SKOS wonderland !

The list will object if I am wrong. For me, SKOS is about "human made 
for human" classification systems. "Broader" means if one (human) is 
interested by the Broader, (s)he will be interested by this too.

The "match" properties are essentially used to correlate different 
classification systems. "Broader_Match" means if one (human) is 
interested by the Broader_Match in (another) classification system, 
(s)he MAY be interested by this too.

In today's world of AI digesting and classifying using statistics rather 
than scientific models and cartesian reasoning, SKOS looks like paddling 
against the tide but... who knows !

Happy New Year, it will be an interesting one !

P.S. This is what ChatGPT has to say on the topic:

How would you explain the similarities and the differences between two 
properties of the SKOS standard: "Broader" and "Broader_Match" ?

SKOS (Simple Knowledge Organization System) is a standard for 
representing thesauri, classification schemes, and other types of 
controlled vocabulary as a set of concepts, and the relationships 
between those concepts.

The "broader" property is a relationship between two concepts in a SKOS 
vocabulary, where the concept on which the property is applied (the 
"narrower concept") is a more specific concept within the hierarchy of 
the vocabulary, and the concept that is the value of the property (the 
"broader concept") is a more general concept. This relationship 
indicates that the narrower concept is a subclass or subcategory of the 
broader concept.

For example, in a vocabulary about animals, the concept "dog" might have 
the broader property with a value of "mammal," because dogs are a type 
of mammal.

The "broader_match" property is similar to the "broader" property, but 
it is used to link a concept in one SKOS vocabulary to a broader concept 
in another SKOS vocabulary. This can be useful when two vocabularies are 
being used together, and there is a need to align the concepts in one 
vocabulary with the concepts in the other vocabulary.

For example, if you are using a vocabulary about animals that includes 
the concept "dog," and you also want to use a vocabulary about pets that 
includes the concept "canine," you could use the "broader_match" 
property to link the "dog" concept in the animals vocabulary to the 
"canine" concept in the pets vocabulary. This would indicate that the 
"dog" concept is a more specific version of the "canine" concept, and 
that the two concepts are related.

In summary, the "broader" property is used to relate concepts within a 
single SKOS vocabulary, while the "broader_match" property is used to 
relate a concept in one SKOS vocabulary to a broader concept in another 
SKOS vocabulary.
