The objective of this study was to describe the care pathway of patients with amyotrophic lateral sclerosis (ALS) based on real-life textual data from a regional coordination network, the Ile-de-France ALS network. This coordination network provides care for 92% of patients diagnosed with ALS living in Ile-de-France. We developed a modular ontology...
Article
To understand the home-based difficulties encountered in the health care pathways of patients with Amyotrophic Lateral Sclerosis (ALS), we must annotate a large amount of textual data, from a database created by the ALS Île de France coordination network. For this purpose, we have developed a modular ontology, consisting of four modules, and a sema...

Article
The Social Psychology perspective provides a new look into the ontology engineering processes. In this paper, we analyze in particular how ontologies, as formal psycho-social entities, are the outcome of influences. The types of influence range from the sources (originating from the experts and the corpus authors) to the ontologists. As it is impos...

Hello everybody,
I would like to use a benchmark with different semantic annotation systems. So, I would like to know if there is a gold standard composed with an ontology and a corpus of text?
Thanks in advance,
Kind regards
