| + | Once you're confident with the standard logo annotation interface, you can try the more powerful Infinite mode available at: https://hunger.openfoodfacts.org/logos/deep-search |
| + | |
| + | The mechanism of Infinite mode annotation is the following: |
| + | |
| + | * fetch all logos annotated with a type and value |
| + | * for each fetched logo, get the most similar logos without annotations |
| + | * display all these unannotated logos |
| + | |
| + | This is a very effective mode to annotate logos that already have a few annotations. |
| + | |
| + | == Product mode == |
| + | If you want to annotate logos of a specific brand or label but infinite mode does not yield any result (because there is no annotated logos yet), you can try bootstrapping logo annotations with product mode: https://hunger.openfoodfacts.org/logos/product-search |

− | Remembering the right label name may be hard sometimes, so here is a list of common label names you will probably see:
| + | Start selecting a type (label or brand) and a value. All logos of all images of all products that have this brand/label will be displayed. You just need to select relevant logos and annotate them. |
