HI all

I wanted to know the version of SNOMED CT that the MedCAT SNOMED model has been trained with. I couldn’t find it any of the documentation.

thanks

Hi Sangeeta,

In general, the ontology is specified in `config.version.ontology` (or in `config["version"]["ontology"]` in older versions of `medcat`) or under “Source Ontology” in the model card.  
In case of the openly available SNOMED model, it reads:

```auto
SnomedCT_InternationalRF2_PRODUCTION_20210131T120000Z

```

So it’s the [January 2021 SNOMED CT International Edition](https://confluence.ihtsdotools.org/pages/viewpage.action?pageId=115899524)

Hi… is there a plan to create a model with a later snomed version ? There are '23 versions available now.
