SEMANTIC ANALYSIS OF INFORMATION
First Claim
Patent Images
1. A method, comprising:
- extracting a subset of data from a data set stored in a data repository;
identifying a format corresponding to the subset of data;
selecting at least one reference data set based upon the format, wherein the at least one reference data set is associated with a known semantic type;
comparing values of the subset of data against the at least one reference data set; and
inferring semantic information of the data set based upon at least one result of the comparing, wherein the semantic information specifies at least a semantic type of data in the data set.

Abstract
Semantic information that describes data sets is inferred based upon a semantic analysis performed on data sets retained within a data repository. The semantic analysis can include a determination of formats associated with fields of the data sets and a comparison of values of the fields against reference data sets having predetermined semantic types. Correlations are inferred between data sets based upon respective semantic information. The correlations are incorporated into visualizations displayed in connection with a graphical user interface.

1. A method, comprising:
-
extracting a subset of data from a data set stored in a data repository; identifying a format corresponding to the subset of data; selecting at least one reference data set based upon the format, wherein the at least one reference data set is associated with a known semantic type; comparing values of the subset of data against the at least one reference data set; and inferring semantic information of the data set based upon at least one result of the comparing, wherein the semantic information specifies at least a semantic type of data in the data set. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A semantic analysis system, comprising:
-
a semantic analysis component configured to infer semantic information regarding data of a data set stored by a system providing information as a service, the semantic analysis component comprising; a format check component configured to identify a format of sample data extracted from the data set and to select one or more reference data sets based upon the format; and a value check component configured to check values of the sample data against the one or more reference data sets to identify a semantic type of the sample data, wherein the semantic analysis component is further configured to infer the semantic information based upon the semantic type identified. - View Dependent Claims (17, 18, 19)

20. A computer-readable storage medium comprising computer-executable instructions that, in response to execution, cause a computing device to perform operations, comprising:
-
identifying a format corresponding to a subset of data extracted from a data set stored in a data repository; selecting at least one reference data set based upon the format, wherein the at least one reference data set is associated with a known semantic type; comparing values of the subset of data with the at least one reference data set; and inferring semantic information about the data set based upon an output of the comparing, wherein the semantic information specifies at least a semantic type of data in the data set.
