target_map¶

Give a string with the name of the image-file that was annotated with the Annotation Compass; Select one or more specific targets and return a list of all labels that include these targets

def target_map(image: str, targets: list ) -> list:
    
    """Give a string with the name of the image-file that was annotated with the Annotation Compass; Select one or more specific targets and return a list of all labels that include these targets."""    

    url = f"https://hub.xpub.nl/soupboat/generic-labels/get-labels/?image={image}"
    response = urlopen(url)
    data_json = json.loads(response.read())     
    
    filter_map = []
    for label in data_json['labels']:
        for target in targets:
            if target in label['text']:
                filter_map.append(label)
    return filter_map

This function was built for a project where individuals are invited to add their annotations on a map using the Annotation Compass. Each annotation-label is stored in a json-file and includes the annotation-text itself, but also the name of the image-file as well as the position, size, index, timestamp and userID of the annotation.

Example for a label:

{'image': 'map.jpg',
'position': {'x': 12, 'y': 97},
'size': {'width': 43, 'height': 18},
'text': 'This is a text! Is this a text?',
'timestamp': 'Wed, 01 Dec 2021 14:04:00 GMT',
'userID': 5766039063}

If interested in all annotations that include one or more specific targets, target_map() can help. The function needs a string with the name of the of the image-file that was annotated with the annotation compass tool as well as one or more specific targets. The output is a list of all labels that include these targets.

How to get a json-file with annotation-labels?

https://hub.xpub.nl/soupboat/generic-labels/

The Annotation Compass allows people to uplaod an image and ask others to annotate it. A json-file of the annotations is provided.

Examples¶

In this example, the function returns all annotation-labels that include two specific targets.
