Enhancing your data by adding predictions to your entity
There will be times where you wish to use the prediction capabilities of Graft to support your use case. Graft enables you to create your own (Custom) Enrichments which can then be used to create predictions, once generated Graft allows you to manage these enrichment models through Active Learning.
Prerequisites
To create an Enrichment you will need labels, Graft supports labels from...
- Their own separate file (previously added as a datasource) which relate to data in the Entity
- i.e. there is a previously unlabeled entry in the Entity that this new label file has an entry for
OR
- The same Entity we are working on
- i.e. one of the data source files already in use in the entity has labels
Alternatively Graft supports advanced functionality to build an Enrichment with no labels called Bootstrapping which can take sample label categories as input and generate initial labels which can be reviewed and corrected.
Training your Enrichment
Once your Enrichment is created, the model will be automatically trained when next opened from the Enrichments tab
Labels in current Entity
- Select the field with the labels from the drop down menu
Graft will generate a preview of the available data
- Click NEXT
- Enter a name for your new enrichment
- OPTIONALLY: Add a description
- Click FINISH
You will be returned to the Enrichments tab
Labels in a separate source
To use a separate file that contains new labels to existing entity instances (rows) Click on the Labels for reviews are located somewhere else radio button
- From the Data Source drop down menu Select the required label file (added through the data source connectors)
- From the Join Key drop down menu Select the field in the new file which is common with the Entity fields, typically this is the Primary Key field
- From the Label drop down menu Select the field containing the labels you would like to add
A preview will be generated to show how the linked data will be joined. In this example you can see the new Label field in Grey
- Click NEXT
- Enter a name for your new enrichment
- OPTIONALLY: Add a description
- Click FINISH
You will be returned to the Enrichments tab
