Understanding the relationship between causes and effects in software requirements is essential for effective software engineering. This blog, we will explore how to use a BERT model to detect cause and effect relationships in sentences, particularly focused on the realm of software requirements engineering.

What is BERT?

BERT, which stands for Bidirectional Encoder Representations from Transformers, is a powerful NLP (Natural Language Processing) model developed by Google. It excels in understanding the context of words in sentences by looking at both the left and right sides of a word, making it a perfect candidate for tasks like cause-effect detection.

How Does It Work?

Imagine you’re a detective tasked with deciphering a message. Each word in a sentence provides clues that tell a story. Some words inform you about actions that have led to outcomes (causes), while others reveal the results of these actions (effects). The BERT model operates in a similar way, assigning one of five labels to each token (word) in the sentence:

• Other: Not related to cause or effect.
• B-Cause: Beginning of a cause phrase.
• I-Cause: Inside a cause phrase.
• B-Effect: Beginning of an effect phrase.
• I-Effect: Inside an effect phrase.

By analyzing these tokens, the model can identify relationships in sentences such as:

If a user signs up, he will receive a confirmation email.

In the example, the model would likely label “signs up” as a cause and “receive a confirmation email” as an effect.

Troubleshooting

While working with the model, you may encounter issues such as:

• Model not loading: Ensure you have the correct versions of the dependencies installed.
• Unexpected labels: This might occur if the input sentence is ambiguous or poorly structured. Try rephrasing it to provide clearer context.
• Performance issues: Make sure you’re running the model on a machine with sufficient computational resources, preferably with a GPU.
