Execution instructions

Run the NER prediction with a command as python -m pvcastro_iberlef.predict_ner --document-path path_to_the_input_document --out-path path_to_the_output_file

Parameters:

• document-path: path to the document containing the text to be predicted for NER, with one token per line, with sentences separated by blank lines.
• out-path: path to the document where the predictions results will be written. Must specify a filename. Example: C:\iberlef\predictions.txt

Observations

Since the IberLEF NER model uses two language models based on ELMo, the trained model ended up quite big, with 1.4Gb aproximately. It takes a while to download it the first time, but the model is cached, so following executions after the first will be quicker.
