| Abstract:
|
This paper is presenting a way of integrating conflicting temporal information from multiple information providers. It is shown that uncertain information can arise when the provider integration process through a global query mechanism requires information not directly presented in the community of information providers. This occurs for two reasons mainly: I) Query selection predicates are directing to level concepts that are at a lower level than those that do exist in the instance level of the database. II) An element in the query selection predicate is a member of more than one high level concepts. A way of integrating conflicting temporal information from multiple information providers considering a property-based resolution is presented. Given are the intuitionistic fuzzy interpretations of the temporal information.
