From the studio, you can use the Semantic-aware analysis to:

The sequence of using the Semantic-aware approach to create pre-configured table analyses involves the following steps:

  1. Connecting to a data source from the studio, whether it is a database, a delimited file or Hive.

    For further information, see Setting up connections to data sources.

  2. Launching the log server where ontology indexes are stored.

    For further information, see Launching the server and setting preferences.

  3. Selecting a table in the data source or a view in a database connection and exploring semantic categories of data columns.

    You can also select to start a Semantic-aware analysis on a set of columns in a table.

    For further information, see Exploring semantic categories of data columns.

  4. Matching column metadata and semantic categories with the concepts from the Ontology repository and outputting the matching results to show the most relevant concepts.

    For further information, see Matching column metadata and semantic categories with the concepts in the Ontology repository.

  5. Defining attributes (semantic) for columns and enriching the Ontology repository with column metadata and semantic categories.

    For further information, see Enriching the Ontology repository.

  6. Running the recommended table analysis and enriching the Ontology repository with analysis results and indicators and patterns used on the analyzed columns.

    For further information, see Defining the recommended table analysis.
