In recent years, there is an increasing demand for sharing and integration of medical data in biomedical research. In order to improve a health care system, it is required to support the integration of data by facilitating semantic interoperability systems and practices. Semantic interoperability is difficult to achieve in these systems as the conceptual models underlying datasets are not fully...

Mapping data to a shared domain ontology is a key step in publishing semantic content on the Web. Most of the work on automatically mapping structured and semi-structured sources to ontologies focuses on semantic labeling, i.e., annotating data fields with ontology classes and/or properties. However, a precise mapping that fully recovers the intended meaning of the data needs to describe the se...

Terminology structuring aims to elicit semantic relations between the terms of a domain. We propose here to exploit definitions found in corpora to obtain such semantic relations. Definition typologies show that definitions can be introduced by different semantic relations, some of these relations being likely to structure terminologies. Our aim is therefore to mine “defining expressions” in do...
