PO² - A Process and Observation Ontology in Food Science. Application to Dairy Gels

International audienceThis paper focuses on the knowledge representation task foran interdisciplinary project called Delicious concerning the productionand transformation processes in food science. The originality of thisproject is to combine data from different disciplines like food composition,food structure, sensorial perception and nutrition. Available datasets are described using different vocabularies and are stored in differentformats. Therefore there is a need to define an ontology, called PO2(Process and Observation Ontology), as a common and standardizedvocabulary for this project. The scenario 6 of the NeON methodologywas used for building PO2 and the core component is implemented inOWL. By making use of PO2, data from the project were structuredand an use case is presented here. PO2 aims to play a key role as therepresentation layer of the querying and simulation systems of Deliciousproject
