Abstract:
This thesis was conducted within the PIMI project, financed by the National Agency of the Research. It concerns the modeling, the querying and thecomposition of personal information. We considered that the use and the accessto personal information is context dependent (e.g., social, geographical). More particularly, it aims to support the user when realising online,administrative or personal procedures. In this setting, the tackled problems arethe representation of heterogeneous information, the context-aware personalinformation spaces querying, the automatic form-filling and the automaticrealization of procedures defined at a high level of abstraction by compositionof online available services.To solve these problems, we have developped several contributions. The first oneconcerns the management of the personal information space. We havedefined a model allowing the description of personal information using severaldomain ontologies. Our model can be instantiated on the user's personalinformation with several usability values depending on the context and with ausability degree. We have also proposed two contextualquerying algorithms SQE and FQE which allow to query the recorded information.The second contribution concerns the use of these information by several onlineservices. It presents two use cases. In the case of the automaticforms-filling, we have proposed an algorithm allowing to generate a semanticquery from an annotated form representation. This query is evaluated by usingboth querying algorithms SQE and FQE. Then, in the case of the user objectiverealization (an abstract procedure) by service composition, we have extendedthe Graphplan algorithm to take into account the contextualization of the dataand the access policy rules specified by the user. The latter allows the user toincrease the control of its information and to limit their leaking.
