Relationship extraction from reports on infectiology cases : experiments on the PARHAF corpus
Thomas Checchin, Julien Jacques, Adrien Guille
Abstract : The task of relation extraction is highly syntax-dependent. Coding a sentence into the AMR framework, an abstract semantic representation in graph form, establishes the links between the semantic concepts in a sentence. Our work explores the extraction of intra-sentence clinical relations, based on AMR encodings, using simple classifiers. We rely on a new French corpus of clinical reports in infectious diseases, PARHAF, as well as a pre-existing AMR parser.
