Knowledge Graph

Connect the knowledge gained by different models.

The Knowledge Graph uses Clarifai's concept mapping model to establish a hierarchical relationship between your concepts. and to uses three different predicates to organize your concepts: hypernyms, hyponyms, and synonyms.

Hyponym represents an 'is a kind of' relation. The following relationship: 'honey' (subject), 'hyponym' (predicate), 'food' (object) is more easily be read as 'honey' 'is a kind of' 'food'.

Hypernym is the opposite of 'hyponym'. When you add one of the relationships the opposite will automatically appear for you in queries. The 'hypernym' can be read as 'is a parent of' so: 'food' (subject), 'hypernym' (predicate), 'honey' (object) can more easily be read as:'food' is a parent of 'honey'.

Synonym The 'synonym' relation defines two concepts that essential mean the same thing. This is more like a "is" relationship. So for example a 'synonym' relationship could be: "puppy" is "pup" The reverse is also true once the former is added so: "pup" is "puppy" will appear in queries as well.

Create

To create a relation between two concepts, you first have to create them in your custom model. See the Concepts page on how to do that programatically.

Each relation has to have specified a predicate, which can be hyponym, hypernym, or synonym.
