The goal of this project is to build a question answering system that performs textual reasoning to answer and pass a 4th grade science exam.

We define process frame as a structure that captures complete information of a scientific process in a structured format. The frame element that we are using currently contains following frame elements.

• Undergoer
• Cause
• Manner
• Result

The system takes descriptive question and four answer choices as input. This is then processed by subsystems shown in the following figure to produce an answer and an associated confidence score.

The following image gives some intuition on how and why structural alignment helps question answering.

The following modules are required to run the system:

• Python 2.7
• NumPy
• Pandas
• Scipy
• scikit-learn
• nltk
• Matplotlib
• Requests
• JSON

and textual alignment service by AI2 (Allen Institute for Artificial Intelligence).
