This a ufal/robeczech-base base model finetuned for span classification. For this model we used IOB-tagging. Using the IOB-tagging schema facilitates the aggregation of predictions over sequences. This specific model is trained on a batch of about 500 span-labeled documents.

This is version was trained with context windows of 128 tokens. For the chunking we used a paragraph-based splitter.

The training was performed with 10 fold CV, with weight averaging of the best epochs per fold.

The input should be a string with Czech cardio clinical text.

CardioNER.cz_128_paragraph is a muticlass span classification model. The classes that can be predicted are ['procedure,medication,disease,symptom'].

The following script converts a string of <512 tokens to a list of span predictions.

To process a string of arbitrary length you can split the string into sentences or paragraphs using e.g. pysbd or spacy(sentencizer) and iteratively parse the list of with the span-classification pipe. You can also use the strider built in the transformer pipeline, although this is limited to non-overlapping strides plus it requires a FastTokenizer and it does not work for aggregation_strategy=None;

CardioCCC; manually labeled cardiology discharge letters; procedure, medication, disease, symptom
