Regarding Taxonomies in order to Ontologies: Customized and you will Semantic Dating

On the example over, the next group of dating are designed, since they are appointed of the ontologist towards brand of instance

At this year’s Taxonomy Training conference, I happened to be anticipate to present to your panel offering 5-moment “Pecha Kucha” lightning talks, in which this year’s motif is actually ontology. Exactly as discover some other understandings and you can uses from “taxonomy,” so might there be some other understandings and you may uses from “ontology.” You could potentially come to if out-of more basics. For people who reach serwis randkowy passion ontologies from the experience of taxonomies and you may the industry of guidance government, then, most merely, an ontology is a very cutting-edge sorts of taxonomy that features wealthier pointers.

In my brief speech, “Of Accidental Taxonomist in order to Accidental Ontologist,” I summarized the difference between taxonomies and you can ontologies as follows:

1. Relationships: Taxonomies enjoys hierarchical and sometimes a simple “associated label” associative, but ontologies keeps semantic dating, that are personalized-created.
2. Term Features: Taxonomies generally don’t possess identity functions, but ontologies create.
3. Title Kinds: Taxonomies generally lack categories having terminology, unless you imagine issues because categories, but ontologies manage.
4. Guidelines/Standards: Taxonomies is to follow the ANSI/NISO Z (2005) otherwise ISO 25964, while ontologies are essential to follow along with the web based Ontology Language (OWL) guidelines and make use of this new Money Breakdown Framework (RDF).
5. Purposes: Taxonomies support indexing/marking, categorization, and/otherwise classification regarding stuff, and in turn guidance findability and you may retrieval. The primary function of an ontology would be to determine a website of real information, and you can help regarding indexing/marking, categorization, classification, findability, and retrieval is supplementary.
6. Tools: Specific software aids the manufacture of just taxonomies, specific application is for ontologies, and lots of software will perform both very well. At exactly the same time, certain taxonomy/thesaurus software can also be help very, if not completely, attributes of ontologies.

As much as possible customize the relationship, does this transform a good taxonomy into the good ontology? No. Customized relationships are merely you to definitely function off a keen ontology, regardless of if even the important ability. During my on the web path toward taxonomies, regardless of if I really don’t train how to come up with ontologies, I really do render a lesson towards the tailored/semantic relationships. This has been preferred by manage an even more state-of-the-art taxonomy instead necessarily appointment all of the conditions from a keen ontology.

The new universal RT relationships, however, try singularly bidirectional

In addition, a personalized matchmaking might not be completely semantic. The newest relationships are also “semantic” as they include certain definition. (Semantic function “have definition.”) You can easily modify relationships when you find yourself nonetheless not leading them to fully semantic. Your elizabeth the high quality relationships for the sorts of application and audience. Such, you could potentially rename broader label (BT)/narrower term (NT) because “ parent/man ,” otherwise rename Relevant Term since “ look for together with .” Whether your taxonomy/thesaurus software is more sophisticated, it will enables you to indicate any number of customized dating, which means that you can include far more nuances off definition.

An extremely important component from its semantic relationship sure-enough from inside the ontologies is the power to would directional dating that are type of inside the for every single guidelines, that have reciprocity. Most of these semantic relationships will be versions out-of “ related title ” (RT), unlike variations of your own hierarchical matchmaking. If you merely designed it by the renaming they, it could need to be a comparable in guidelines, such as for example possess “ have spouse .” To help make a semantic matchmaking couple, such as for instance Man ( manufactures ) and you can IND ( manufactured by the ), need a hack one helps ontological relationship and not soleley “customized” dating.

If the product supporting tailored relationship however the ability to manage distinctive line of sets from directional relationship that are associative in place of hierarchical, the outcomes cans nevertheless be quite beneficial. You’ve got good “close ontology” if you don’t a solely outlined ontology. Including, you might rename the only one “ relevant name ” (RT) because “ Manufacturer-Produc t” that have an acronym eg Guy-Specialist (Borrowing to Alice Redmond-Neal out of Supply Inple). Thus, the connection is the same in a choice of guidelines:
