From Talend Studio, you can use the Semantic-aware analysis to:
- explore the semantic categories and query complex semantic relationships in the data you analyze,
- create table analyses preconfigured with indicators and patterns that best suit the data.
- index and enrich the ontology repository on the log server with semantic categories and
For a list of all the dictionary indexes and regex categories used in the Semantic-aware analysis, see List of the indexes and regex categories used in the Semantic-aware analysis.
For further information about the content of the ontology repository, see The ontology repository.
The sequence of using the Semantic-aware approach to create pre-configured table analyses involves the following steps:
- Connecting to a data source from the studio, whether it is a database, a delimited file
For further information, see Creating connections to data sources.
- Launching the log server where ontology indexes are stored.
For further information, see Launching the server and setting preferences.
- 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.

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