fpt-comments-sentiment

This is a hand-curated Vietnamese feedback dataset built from FPT-related discussions across Facebook communities, FuOverflow, Reddit/VOZ-style forums, FPT web pages, and other student-community sources. (Inspired by the NEU-ESC dataset)

The data is curated by manually collected examples with Facebook group comments scraped using Playwright, then cleaned, redacted, hand-reviewed, and labeled with support from LLM-assisted review.

Each row contains a redacted comment with two labels: one for sentiment and one for topic. The dataset is intended for Vietnamese sentiment analysis, toxicity detection, and community-topic classification in FPT University contexts.

This dataset is created solely for use within the FPT coursework.

The text was redacted before export. The CSV files do not include raw author names, profile URLs, post URLs, permalinks, response URLs, or scrape IDs.

Toxic labels are intended for targeted abuse, insults, slurs, hostile commands, or similar direct attacks. Profanity alone was not treated as Toxic.
