Systems and methods relate to auto-tagging of data in a data lake or a data storage. Generating a statistical summary of the data lake and interactively receiving data in a selected column of an exemplar data addresses an issue of efficiently and accurately auto-tagging data in a data lake. The present disclosure automatically generates a statistical summary of the data lake using a lightweight off-line processing. A graphical user interface interactively receives an exemplar data file with a selection of a column in the exemplar data file. A list of candidate data-tagging patterns is generated based on the statistical summary and updates the list by removing candidate data-tagging patterns that under-generalize the data. The present disclosure determines a data-tagging pattern by selecting a candidate data-tagging profile from the list based on having the least number of matching columns in the data lake.

Method and system for automatically tagging data

Techniques are described herein that are capable of performing metadata extraction based on resource attributes and user-defined policy and topology. A hierarchical resource-grouping construct, which is selected from hierarchical resource-grouping constructs in a user-defined hierarchical resource-grouping topology of a cloud computing service account, is registered by enumerating at least a subset of the constructs. The subset includes the selected construct and each other construct encompassed by the selected construct. Metadata is selectively extracted from the constructs that are included in the subset to provide extracted metadata based at least in part on one or more user-defined policies, which are assigned among the constructs that are included in the subset, indicating whether the metadata is to be extracted as a result of resources associated with the constructs included in the subset having specified attributes. A searchable catalog is generated that includes the extracted metadata.
