ReaSCAN: Compositional Reasoning in Language Grounding

ReaSCAN is a synthetic navigation task that requires models to reason about surroundings over syntactically difficult languages.

Release Notes

Getting Started

Step 1: Download ReaSCAN

We generated ReaSCAN using our pipeline with fixed random seeds. You can reproduce the version of ReaSCAN we use in the paper by running the pipeline. Additionally, we also update the version we use to a online folder where you can directly download and use as-it-is. Note that, the dataset files are really large. It may take a while to download them.

Our generated data is in ReaSCAN-v1.0.zip (Note that we updated our files to hotfix some of existing issues at 06/16/2021), which is saved in a shared drive. The dataset consists subsets generated for different patterns (P1: Simple (similar to gSCAN), P2: 1-relative-clause, P3: 2-relative-clauses, P4: 3-relative-clauses) and different compositional splits (see our paper for details about each split).

Random splits that can be used for training your models,

Compositional splits that are designed to be zero-shot testing splits,

You can also generate your own compositional splits by modifying couple lines in code/dataset/generate_ReaSCAN_splits.ipynb.

Step 2: Loading ReaSCAN

Once you generate the dataset .txt file (in json format), you can simply load any dataset as,

import json

path_to_data = "data-compositional-splits.txt"
logger.info(f"Reading dataset from file: {p1_path_to_data}...")
data_json = json.load(open(path_to_data, "r"))

print(data_json["examples"].keys())
