Query expansion and semantic visualization in information system cooperations : methods and tools for information retrieval
2010
This thesis presents approaches and tools for information retrieval. Our work is part of a cooperation system based on ontologies called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). We treat the problem of information retrieval by providing an enrichment method called QUEXME (QUery EXpansion MEthod) of queries based on analysis of user behavior and using the concept importance notion with regards to query. We also discussed the problem of visualization in the OWSCIS system offering a architecture of service visualization. It is composed of three modules: the request, enrichment and results. The approaches proposed in this thesis have been prototyped and the te…
Peroxydation des lipides émulsionnés et transfert d'ions fer à l'interface huile / eau stabilisée par des protéines de lait : influence des résidus p…

Iron incorporated into food systems induces oxidation and precipitation. The consequences are a reduced bioavailability and a modification of other food flavor. The iron chelates such as Fe-bisglycinate and Fe-EDTA represent a possibility to avoid side effects, since the iron is protected. The inertety of Fe bisglycinate and NaFe EDTA for lipid peroxidation has been verified in oil-in-water emulsion models stabilized by sodium caseinate or by β lactoglobulin through the following studies: i/ increase of primary and secondary products of oxidation, ii/ change of the properties of the oil/water interface (tension and interfacial rheology), iii/ the stability of the chelate iron (Fe-bisglycina…
