Is a Question Decomposition Unit All We Need

Summary

In this paper, the authors have shown the affect of question decomposition over 8 datasets. The decomposed questions they have generated are human annotated. They have used 50 data for each dataset, in total 400 data points.

Contributions:

  1. A very big contribution is the dataset
    1. The dataset is small of 50 data from 8 datasets = 400 data rows
    2. But, The dataset is human annotated, so a gold dataset for decomposed questions.

Limitations / Future Works

  1. Though this work provides a good decomposed dataset, but in real life its too expensive to create a human annotated decomposition for each dataset. so this paper lacks the automatic creation of decomposed question.

Annotations

Annotation

« can we modify data by expressing it in terms of the model’s strengths, so that a question becomes easier for models to answer? »()

Annotation

« Human-in-the-loop Question Decomposition (HQD) can potentially provide an alternate path to building large LMs »()

Annotation

« Inspired by humans, who oftenview new tasks as a combination of existing tasks, »()

Annotation

« In a decomposition chain,if the answer in one step goes wrong, it propagatestill the end and the final prediction becomes wrong »(4)
