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; 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 values included in 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; at least one of the selecting, identifying, comparing and inferring steps being performed by at least one processor.
