Requirements

1. Download the SpatialSense dataset from to the root of this repo. Unzip images.tar.gz.
2. Download and install Miniconda Python 3 (Anaconda should also work).
3. Install Python dependencies using conda: conda env create -f spatialsense.yaml && conda activate spatialsense. If you have troubles with the aforementioned two steps, you may manually install the packages in spatialsense.yaml in whatever way that works for you.
4. Download the pre-trained Word2Vec model GoogleNews-vectors-negative300.bin.gz. to ./baselines.

Dataset

Data Format

The annotation.json file contains a list in which each element contains the annotations for a single image. For example, the first element is:

{
  'url': 'https://farm4.staticflickr.com/3543/5704634119_8b8ccf3229.jpg',  # URL for Flickr Images
  'nsid': '10392797@N03',                                                  # Flickr NSID of the user
  'height': 500,
  'width': 281,
  'split': 'train',                                                        # train/valid/test split
  'annotations': [{                                                        # a list of spatial relations
    '_id': '59fbffe4f25c8070bb77ec42',                                     # an unique identifier for the relation      
    'predicate': 'on',               
    'object': {
      'y': 402,                                                            # (x, y) is a point on the object
      'x': 148,
      'name': 'ground',
      'bbox': [196, 500, 3, 278]                                           # bounding box
    },
    'subject': {
      'y': 317, 
      'x': 157, 
      'name': 'cat', 
      'bbox': [230, 434, 31, 264]
    },
    'label': True                                                          # the relation is a positive example
    }, {
    '_id': '59ff0e910de0c80e4077c5f0',
    'predicate': 'to the left of',
    'object': {
      'y': 213,
      'x': 240,
      'name': 'mirror',
      'bbox': [0, 345, 160, 280]
    },
    'subject': {
      'y': 303, 
      'x': 143, 
      'name': 'cat', 
      'bbox': [226, 449, 33, 271]
    },
    'label': True},
  ...  
  ]}

Conventions for coordinates and bounding boxes: The origin is the upper-left corner of an image; the x-axis is along the width, and the y-axis is alone the height. A bounding box [y0, y1, x0, x1] has (x0, y0) as its upper-left corner and (x1, y1) as its bottom-right corner.

Visualizations

To visualize the relations in SpatialSense: python visualize.py

Spatial Relations in 3D

In a more recent paper, we constructed Rel3D: the first large-scale, human-annotated dataset for grounding spatial relations in 3D. It enables quantifying the effectiveness of 3D information in predicting spatial relations. Moreover, we propose minimally contrastive data collection—a novel crowdsourcing method for reducing dataset bias. The examples in Rel3D come in minimally contrastive pairs: two examples in a pair are almost identical but have different labels.
