International Conference Bioinformatics Biomed, 1–4. https://doi.org/10.1109/BIBM.2012.6392613http://hdl.handle.net/10400.22/14325In this work we build the first BI-RADS parser for Portuguese free texts, modeled after existing approaches to extract BI-RADS features from English medical records. Our concept finder uses a semantic grammar based on the BIRADS lexicon and on iterative transferred expert knowledge. We compare the performance of our algorithm to manual annotation by a specialist in mammography. Our results show that our parser's performance is comparable to the manual method.engFeature extractionBreast cancerBI-RADS descriptorsconference object10.1109/BIBM.2012.6392613
