Project: Signora — Voice-of-Customer Intelligence

Repository: Miraj-world/Signora

Summary

Today’s work focused on improving the reliability and traceability of the public Reddit review dataset, adding integrity checks, documenting the project, and publishing the initial codebase to GitHub.

The primary outcome was a cleaner and more accurately classified dataset, supported by automated tests and publicly available project documentation.

Completed Work

1. Dataset Metadata Cleanup

Updated:

scripts/build_voc_dataset.py

The dataset-building pipeline was corrected to improve product identity, metadata accuracy, and Reddit conversation structure.

2. Sony Product Identity Correction

Previously mislabeled Sony records were separated into the following product identities:

• Sony WH-1000XM4
• Sony WH-1000XM5
• Sony WH-1000XM6
• General Sony WH-1000X series

This prevents feedback about different headphone generations from being incorrectly analyzed as feedback about the XM5.

3. Amazon Echo Dataset Expansion

Broadened the Amazon dataset scope from only Echo Dot reviews to general Amazon Echo and Alexa feedback.
