You can configure AEM Assets to automatically add smart tags to any image asset that you upload to a new folder.
To use the Smart Tagging cloud service in AEM Assets, see Configuring Smart Tagging Cloud Service.
Navigate to the Properties page of an image in the folder. The automatically-applied tags appear under Smart Tags.
The number that is shown next to the smart tags is the confidence level. In this case, the tagging algorithm is 85% confident that the tag "business" is relevant to the image of Scott Reynolds. This number is extremely important for search. AEM ranks the search results based on the confidence scores, which generally improves search results beyond what an inspection of the assigned tags of any image suggests. Any inaccurate tags often have low confidence scores so they seldom appear at the top of search results. Therefore, you generally need not curate the smart tags.
AEM applies a minimum confidence threshold for the smart tags to avoid having too many tags for each image, which slows down indexing. The default threshold is 50%. It may not be the optimal threshold for all users. Therefore, Adobe encourages you to experiment with this value. If some images are not tagged, it may indicate that the algorithm is less than 50% confident in the predicted tags.
In the CRX repository, smart tags are stored at a separate location from the tags that are assigned manually and do not interfere with the manual tags in any way. Therefore, there is no risk of interference or "contamination" of the manual tags. Also, manual tags are assigned a confidence of 100% (maximum confidence). Therefore, if there are images with manual tags that match the search query, they are displayed before smart tags matching the search query.
To apply automatic smart tagging on folders that already contain image assets, use Folder Settings. In this case, only the images that you upload after enabling this option are automatically tagged. To apply tags on pre-existing images in a folder, separately configure a background job that periodically tags these images in batches. By default, the background job runs every 24 hours at 12:00 AM and tags image assets in batches of 1000. If necessary, you can modify the frequency, time, and batch size for the job.
You can automatically add smart tags to image assets within a folder by applying the DAM Smart Tag Assets workflow on the folder.
Navigate to the Properties page of any image asset in the folder. The smart tags appear under Predicted Tags. The number that appears beside the name of each tag is the confidence that AEM Assets assigns regarding how suitable the tag is to be used for the particular image. For example, the 84 beside the name of a tag indicates that AEM Assets assigns an 84% confidence level regarding the appropriateness of the tag for the image asset.
After you enable automatic smart tagging on a new folder or run the automatic smart tagging workflow on images in bulk, you can verify the augmented search capability by searching for image assets based on relevant tags that you haven't explicitly added to images.
