Start by clicking the Sources icon in the sidebar. To edit the source click “View” on the top right of the source you would like to make changes to.

From here you can edit the Source Name and Description by clicking the little pencil beside. The pencil only appears when your scroll over it.

To delete a source choose Delete from the dropdown, and enter the name of the source you wish to delete. Deleting a source is permanent and doesn't affect your comment usage. This means that if you create a source from a CSV file with 500 comments, these comments will count towards your monthly usage even if you delete the source.

As such, you might want to deselect the source in the analysis interface, rather than deleting it permanently in case you want to continue using it for text mining in the future.

When the enrichment of metadata is processing, you will see a progress bar appear to let you know what stage you are at.
