SEMANTIC ANALYSIS OF INFORMATION

摘要

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:
selecting a subset of data from a data set stored in a data repository; identifying a format in which values in the subset of data are represented by comparing a structure of at least one value in the subset of data to a plurality of known data patterns; inferring a candidate semantic type of data in the data set based on the identified format; validating values of the data in the data set against a set of domain rules, the set of domain rules establishing valid data values for the candidate semantic type; and presenting invalid values to a user, the invalid values representing values of the data in the data set that are disallowed by the set of domain rules; at least one of the selecting, identifying, inferring, validating and presenting steps being performed by at least one processor.
