Broad-coverage biomedical relation extraction with SemRep

Towards a Broad-Coverage Biomedical Ontology Based on Description Logics

We describe an ontology engineering methodology by which conceptual knowledge is extracted from an informal medical thesaurus (UMLS) and automatically converted into a formal description logics system (LOOM). Our approach consists of four steps: concept definitions are automatically generated from the UMLS, integrity checking of taxonomic and partonomic hierarchies is performed by LOOM's termin...

Kernel-based learning for biomedical relation extraction

Biomedical Relation Extraction: From Binary to Complex

Biomedical relation extraction aims to uncover high-quality relations from life science literature with high accuracy and efficiency. Early biomedical relation extraction tasks focused on capturing binary relations, such as protein-protein interactions, which are crucial for virtually every process in a living cell. Information about these interactions provides the foundations for new therapeut...

Broad-coverage CCG Semantic Parsing with AMR

We propose a grammar induction technique for AMR semantic parsing. While previous grammar induction techniques were designed to re-learn a new parser for each target application, the recently annotated AMR Bank provides a unique opportunity to induce a single model for understanding broad-coverage newswire text and support a wide range of applications. We present a new model that combines CCG p...

Towards Broad Coverage Surface Realization with CCG

This paper reports on progress towards developing the first broad coverage English surface realizer for Combinatory Categorial Grammar (CCG). The paper provides initial automatic evaluation results which are roughly comparable to those reported with other formalisms when using a (nonblind) grammar derived from the development section of the CCGbank; the results are worse, though still respectab...
