Abstract: A system for creating a semantic data warehouse including a convergence service configured to execute queries to connected data sources, to convert data from source to domain semantics, and to aggregate converted data. The convergence service is configured to invoke by an entity graph service that, on demand, defines a semantic entity representation, the needed queries and data sources to be queried; and projects and makes available the resulting data in the semantic entity representation.

Abstract: In a computer-implemented method of querying a data repository wherein a software image is generated of at least one of a pre-compiled semantic reasoning engine, a set of pre-compiled fact data, and pre-compiled reasoning rules. At runtime additional run time data and/or run time reasoning rules are loaded. A query is specified and solved by means of the software image and the additional run time data and/or runtime rules.

Abstract: A method for generating rules for rule-based reasoning includes the steps of starting from a set of generic reasoning rules generating a set of specific reasoning rules by substituting in at least one of the generic reasoning rules having more than one variable, at least one of the variables with (a) class(es) defined in an ontology.

Abstract: Data regarding at least one event are extracted from a data repository and subjected to a syntactic transformation into a first semantic representation if needed. Extracted and transformed data are converted into a representation with explicit semantics regarding temporal information. If the extracted data includes no explicit temporal data, temporal data are deduced from other extracted data pertaining to the event and attached to the event data. The results can be applied for temporal reasoning.

Abstract: A method of using a semantic web data source in a target application includes the target application calling the application program interface of a bridge component, and the bridge component retrieves the required data from the semantic web data source, translates the retrieved data semantically and syntactically to reflect the meaning and syntax of the target application, and returns the translated data in the format of the target application.

Abstract: Method of generating a number of steps constituting an adaptable clinical workflow based on a recursive approach in which for each step of the workflow the following steps are executed: Selecting a number of knowledge bases to be included in a reasoning step on the basis of (a) goal(s), generating (a) query(ies) taking into account the goal(s), applying the selected knowledge bases and the generated queries to a reasoning engine so as to generate a solution, interpreting this solution by translating the solution given in a formal representation into (an) executable action(s) for the current step in the clinical workflow.
