|
Overview |
|
|
-------- |
|
|
REX is an ontology of physico-chemical processes, i.e. physico-chemical changes occurring in course of time. |
|
|
REX includes both microscopic processes (involving molecular entities or subatomic particles) and macroscopic processes. |
|
|
Some biochemical processes from Gene Ontology (GO Biological process) can be described as instances of REX. |

------------- |
|
|
.. code-block:: python |
|
|
|
|
|
from ontolearner.ontology import REX |
|
|
|
|
|
# Initialize and load ontology |
|
|
ontology = REX() |
|
|

|
|
|
|
|
# Extract datasets |
|
|
data = ontology.extract() |
|
|
|
|
|
# Access specific relations |
|
|
term_types = data.term_typings |
|
|
taxonomic_relations = data.type_taxonomies |
