| Physico-chemical process ontology (REX) |
| ======================================================================================================================== |
|
|
| 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. |

| Usage Example |
| ------------- |
| .. code-block:: python |
|
|
| from ontolearner.ontology import REX |
|
|
| # Initialize and load ontology |
| ontology = REX() |
| ontology.load("path/to/ontology.OWL") |
|
|
| # Extract datasets |
| data = ontology.extract() |
|
|
| # Access specific relations |
| term_types = data.term_typings |
| taxonomic_relations = data.type_taxonomies |
