TLDR; this repository maintains a community effort to create a large collection of tasks and their natural language definitions/instructions. Check the releases for the summary of the latest changes and additions to the tasks.
If you have any suggestions to improve the data, let us know. We're looking for more contributions to make this data better and bigger! 🙌

• May 2022: We released the several models trained on our data. Check out the code and checkpoints.
• April 2022: A paper on our data is out!
• October 15, 2021: the goal date for the our v2 dataset.
  • The community have contributed over 1500 tasks!! 🎉
  • We are working on cleaning up the new tasks and publishing a paper summarizing our new findings!
  • You can still submit new tasks! The new tasks will be part of the future data releases.
• Sept 2021: general call for contributions is out!
• June 2021: we initiated this repository with 61 tasks!

While the current dominant paradigm (supervised learning with task-specific labeled examples) has been successful in building task-specific models, such models can't generalize to unseen tasks; for example, a model that is supervised to solve questions cannot solve a classification task. We hypothesize that a model equipped with understanding and reasoning with natural language instructions should be able to generalize to any task that can be defined in terms of natural language.

In our earlier effort, we built a smaller data (61 tasks) and observed that language models benefit from language instructions, i.e., their generalization to unseen tasks when they were provided with more instructions.
Also, generalization to unseen tasks improves as the model is trained on more tasks.

We believe that our earlier work is just scratching the surface and there is probably so much that be studied in this setup. We hope to put together a much larger dataset that covers a wider range of reasoning abilities. We believe that this expanded dataset will serve as a useful playground for the community to study and build the next generation of AI/NLP models. See this blog post for a summary of the motivation behind this work.

Each consists of input/output. For example, think of the task of sentiment classification:

• Input: I thought the Spiderman animation was good, but the movie disappointed me.
• Output: Mixed

Here is another example from the same task:

• Input: The pumpkin was one of the worst that I've had in my life.
• Output: Negative

Additionally, each ask contains a task definition:

Given a tweet, classify it into one of 4 categories: Positive, Negative, Neutral, or Mixed.

Overall, each tasks follows this schema:

Or if you're comfortable with json files, here is how it would look like:

{
  "Contributors": [""],
  "Source": [""],
  "URL": [""],
  "Categories": [""],
  "Reasoning": [""],
  "Definition": [""],
  "Input_language": [""], 
  "Output_language": [""],
  "Instruction_language": [""],  
  "Domains": [""],    
  "Positive Examples": [ { "input": "", "output": "",  "explanation": ""} ], 
  "Negative Examples": [ { "input": "", "output": "",  "explanation": ""} ],
  "Instances": [ { "id": "", "input": "", "output": [""]} ],
}

We would appreciate any external contributions! 🙏 You can contribute in a variety of ways.

• If you think an important task is missing, you can contribute it via Pull-Request. You can also get inspirations from the task suggestions in the Github issues which you can sign up to work on.
• If you have any other suggested tasks but you're not sure if they're good fit, bring them up in the issues.
• If you have any questions or suggestions, please use the issues feature.
• If you're addimg a new task, make sure to review the following guidelines:
  • Each task must contain contain a .json file that contains the task content. You can look inside the tasks/ directory for several examples.
    • Make sure that your json is human readable (use proper indentation; e.g., in Python: json.dumps(your_json_string, indent=4, ensure_ascii=False))
    • Make sure that you json file is not bigger than 50MB.
    • Make sure your task has no more 6.5k instances (input/output pairs).
    • Each instance must have a unique id, which should be the task number plus a string generated by uuid.uuid4().hex. E.g., task1356-bb5ff013dc5d49d7a962e85ed1de526b.
    • Make sure to include task category and domains, based on this list.
    • Make sure to number your task json correctly
      • Look at the task number in the latest pull request, task number in your submission should be the next number.
      • Make sure to include the source dataset name and the task type when naming your task json file.
        • You can use this format: taskabc_<source_dataset>_<task_type>.json E.g. in task001_quoref_question_generation.json, the source dataset is quoref and the task is question generation.
    • Note that, source need not necessarily be a dataset and can be a website e.g. leetcode.
      • If you have created the json without any reference, use synthetic in place of source.
    • You should have one pull request per dataset. Name your pull request as Task Name <start_task_number>-<end_task_number>.
    • If you're building your tasks based existing datasets and their crowdsourcing templates, see these guidelines.
  • Add your task to our list of tasks.
  • To make sure that your addition is formatted correctly, run the tests: > python src/test_all.py
    • To only test the formatting of a range of tasks, run > python src/test_all.py --task <begin_task_number> <end_task_number>. For example, running > python src/test_all.py --task 5 10 will run the test from task005 to task010.

As is introduced in our paper, this dataset can be used for systematic study of cross-task generalization, i.e., training on a subset of tasks and evaluating on the remaining unseen ones. To make the comparison among different methods easier, we create an official split here, as is described in the paper. You can follow the instructions to set up your experiments.

We also released our experiment code and checkpoints for reproducibility and future research.
