  • Patent number: 11531717
    Abstract: Data records are linked across a plurality of datasets. Each dataset contains at least one data record, and each data record is associated with an entity and includes one or more attributes of that entity and a value for each attribute. Values associated with attributes are compared across datasets, and matching attributes having values that satisfy a predetermined similarity threshold are identified. In addition, linkage points between pairs of datasets are identified. Each linkage point links one or more pairs of data records. Each data record in the pair of data records is contained in one of a given pair of datasets, and each pair of data records is associated with a common entity having matching attributes in the given pair of datasets. Data records associated with the common entities are linked across datasets using the identified linkage points.

  • Patent number: 9996607
    Abstract: Described herein are methods, systems and computer program products for entity resolution. Entity resolution, also known as entity matching or record linkage, seeks to identify equivalent data objects between or among datasets. An example method includes creating a deterministic model by defining an entity to be resolved, selecting two datasets for comparison, defining matching predicates for attributes of the datasets to select a set of candidate matches, and defining a precedence rule for the candidate matches to select a subset of the candidate matches. The method includes running the deterministic model on the two datasets. Running the deterministic model includes applying the matching predicates and the precedence rule to data in the datasets that correspond to the attributes. The method also includes applying a cardinality rule to results of the running, and outputting the matching candidates for which the cardinality rule is satisfied.

  • Patent number: 8884675
    Abstract: The slew rate of a transistor is controlled. Upon a transition of a MOSFET control signal, an operating voltage of the MOSFET is measured and a determination of whether the voltage is between a predetermined set of values is made. Based upon the determination, a counter is incremented, and the count of the counter corresponding slew rate. The turn-on current of the MOSFET is controlled based upon the count.

  • Publication number: 20130091184
    Abstract: Embodiments of the invention relate to correlating schema mappings. In one embodiment, a set of schema mappings over a source schema and a target schema are received. Each of the schema mappings is decomposed into a basic schema mapping. A first set and second set of relations re determined for the source schema and the target schema, respectively. Each relation in the first set of relations is paired to at least one relation in the second set of relations. The pairing forms multiple relation pairs between the first set and second of relations in the form of (T, T?), where T is a source portion of a relation pair and T? is a target portion of the relation pair. A set of basic schema mappings is identified that matches the relation pair. Each basic schema mapping is merged into a single schema mapping.
