For german you have a lot of possible forms which makes training difficult. Like training
ein/eine/einer/eines in front of the entity
Are the trained words used as training or some lemmatized form?
So I would just like train
ein Hotel instead together with
eines Hotels
einem Hotel
If just used the pure word you need for german train all posible grammar form, because otherwise entity will not extracted?
Where would I have to implement my own Stemmer?
