摘要： Data elements from data sources and having a data value set are linked by using hash functions to determine a dimensionally reduced instance signature for each data element based on all data values associated with that data element to yield a plurality of dimensionally reduced instance signatures of equivalent fixed size such that similarities among the data values in the data value sets across all data elements is maintained among the plurality of instance signatures. Candidate pairs of data elements to link are identified using the plurality of instance signatures in locality sensitive hash functions, and a similarity index is generated for each candidate pair using a pre-determined measure of similarity. Candidate pairs of data elements having a similarity index above a given threshold are linked.

摘要： The present disclosure provides systems and methods that generate query templates that are expressed in a generic schema-agnostic language. The query templates can be generated “from scratch” or can be automatically generated from existing queries, a process which may be referred to as “templatizing” the existing queries. As one example, generation of query templates can be performed through an iterative process that iteratively generates candidate templates over time to optimize a coverage over a set of existing queries. After generation of the schema-agnostic query templates, the systems and methods described herein can automatically translate/map the templatized queries into “concrete,” schema-specific queries that can be evaluated over specific customer schemas/datasets. In this manner, a query template for a given semantic query (e.g., “return the names of all employees”), is required to be written only once.

摘要： A method for representing and querying incomplete and uncertain information in graph data receives a plurality of graphs containing subject nodes, object nodes and predicates extending between subject and object nodes. The subject nodes and predicates can be URIs or blank, and the object nodes can be URIs, literals or blank. Incomplete graph data sets are created by a variable into each blank subject node, each blank predicate and each blank object node, and uncertain graph data sets are created by substituting alternative values for all variables in the incomplete data graph. A query is received from a user and a naïve search of the graph data is performed for certain data. The incomplete and uncertain graphs are then used to determine potential answers and certain potential answers based on user-specified requirements. The certain answers and potential certain answers are returned to the user.
