One of the goals of governance is to make data assets comprehensible and accessible to all. One way of achieving this is by creating links between data.
MetaBot uses analysis and text-processing techniques to identify lexical similarities between objects, relying mainly on their labels, to suggest links to be created between the objects in your data catalog. Two types of links are suggested:
- Implementation links, between glossary objects and dictionary objects
- Usage links, between glossary objects and usage objects
This feature is visible to all users with editing rights on the glossary and/or:
- the dictionary (to generate implementation links)
- usages (to generate usage links)
To find out more about MetaBot's features, see MetaBot.
Launch automatic link generation
- Click on Suggest links from the actions menu (⋮) of any object in the glossary, dictionary or usages tree. A modal opens to explain the feature; you can check the box if you don't want it to appear next time.
- Select the objects to which you'd like MetaBot to generate links.
- Click on Generate to start link generation. It may take a few moments, depending on the volume of objects selected, and you can continue browsing the platform until the operation is complete.
- Wait for MetaBot's notification, which informs you that the links have been successfully generated to the object of your choice.
Manage the generated links
From the AI suggestions panel of an object card
Once link generation is complete, you can consult the list of generated links to validate them. They are visible from an object's service panel, in the AI suggestions panel opened from the toolbar of the object card.
This panel also includes all suggestions for data tagging and classification. To find out more, see Data classification via MetaBot.
The suggestions in this panel are organized by suggestion type under different sections, including a section dedicated to link suggestions. Each suggestion has a confidence score.
If the suggested link seems relevant, you can accept the suggestion. A link is then automatically created between the 2 objects and is visible in the linked objects tab, along with the lineage. You can also reject a suggestion if it doesn't interest you.
You can also accept or reject all suggestions in bulk with the buttons that appear when hovering over the suggestion type.
From the Suggestions center
In the Suggestions center (Suggestions in the left menu), the first tab is named Links. The other tabs are Tags, PII, Glossary and Descriptions. It groups all suggested implementation and usage links in all the spaces to which you have access.
You can filter on the space and version of your choice to find the suggested links that interest you. The filter applies to all Suggestions center tabs (except the Glossary tab).
Each line of the table represents a suggested link made up of:
- the glossary object
- the link type (implementation or usage)
- the object to be linked
- the confidence score
When you hover over a line, buttons appear to accept or reject the suggested link. If you accept it, a link is created automatically between the 2 objects, visible in the linked objects tab and, depending on the link type, on the lineage. You can also decline a suggestion that doesn't meet your requirements.
To accept or reject all link suggestions en masse, click on Accept all or Reject all. This bulk action applies only to the suggestions visible in the panel.
You can also sort the suggestions by last suggestion date or by confidence score. To load more suggestions, click on the button that displays the other pending suggestions.
