Step 2
General Objects: Sign
Text in the Image: Text of 'Deep Learning'
Objects that specifically refer to the Proper Noun of the Real World: N/A

Step 3
triplets: [Sign, General Objects, displays, Text of 'Deep Learning', Text in the Image]

Step 4
(1) Node with max degree: Sign.
(2) Location of Sign: [Center of the canvas].
(3) Location of Text of 'Deep Learning': [Center of the Sign].

Step 5
Bounding Boxes of the Objects:
Sign, General Objects: [0.100, 0.200, 0.900, 0.800] - The sign occupies a central position in the image, large enough to be prominent.
Text of 'Deep Learning', Text in the Image: [0.300, 0.400, 0.700, 0.600] - The text is centrally placed within the sign.

Step 6
{"Sign": {"phrase": "Sign","coordinates": [0.100, 0.200, 0.900, 0.800]},
 "Deep Learning": {"phrase": "Text of 'Deep Learning'","coordinates": [0.300, 0.400, 0.700, 0.600]}}
