Abstract:
In a computer-implemented method of querying a data repository wherein a software image is generated of a 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 query rule set is created by applying a query generation query rule to an inference rule set so as to generate a query rule set via a reasoning process executed by a reasoner whereby said reasoner answers said query generation query rule by taking the basic graph pattern of the conclusion of one or more inference rules in said inference rule set and generating a corresponding query rule for said basic graph pattern, wherein in said generated query rule both premise and conclusion are using said basic graph pattern.
Abstract:
A system for creating a semantic data warehouse comprising a convergence service for executing queries to connected data sources, converting data from source to domain semantics and aggregating converted data characterized in that - said convergence service is invoked 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 said semantic entity representation.
Abstract:
A method to link instances expressed in at least two EHR systems by means of URIs constructed with different identifier sets by processing RDF data of said instances to link the instances by generating re-labeling statements and applying the re-labeling statements to the RDF data to consolidate the URIs with different identifier types to a single URI with a master identity.
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 comprise 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 wherein - said target application calls the application program interface of a bridge component, - said 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.
