I thank you for your efforts. Several days ago, I created a proposal for risk factor so that it can be added as a Wikidata property. https://www.wikidata.org/wiki/Wikidata:Property_proposal/risk_factor. The status of the proposal is currently ready. This means that the property is eligible for creation. That is why I invite you to create it so that I can organize this week a Skype discussion about our method of the automatic enrichment of Wikidata with risk factors. Of course, in this online meeting, I will absoolutely show the method in details and adjust it according to your opinions.
