Basic CRF approach to DIANN 2018 shared task
This paper describes the UPC 2 system participation in DIANN (Disability annotation on documents from the biomedical domain) shared task, framed in the IBEREVAL 2018 evaluation workshop1. The system tackles the detection of disabilities using a CRF to perform IOB Named Entity Recognition (NER). Regarding the detection of negated disabilities, the out-of-the-box NegEx rule-based system is used.
