VLSP2018-ABSA-Hotel

Dataset Summary

The VLSP 2018 Hotel corpus is designed for Vietnamese Aspect-Based Sentiment Analysis (ABSA), covering two sub-tasks of Aspect Category Sentiment Analysis (ACSA):

1. Aspect Category Detection (ACD): identify which Aspect#Category pairs are present in each review.
2. Sentiment Polarity Classification (SPC): assign one of three sentiment labels (Positive, Negative, Neutral) to each detected Aspect#Category.

This unified CSV contains 5,600 reviews with a type column for train/dev/test and binary indicators for each aspect–category (0=no, 1=positive, 2=negative, 3=neutral).

Supported Tasks and Metrics

• Aspect Category Detection: multi-label classification
• Sentiment Polarity Classification: multi-class classification
• Metrics: Precision, Recall, F1 (for both ACD and SPC)

Languages

• Vietnamese

Dataset Structure

Column	Type	Description
Review	str	The raw hotel review text.
<Aspect#Category> (34 columns)	int	One-hot+polarity indicator per aspect#category (0/1/2/3).
type	str	Split: train / validation / test.
dataset	str	Always VLSP2018-ABSA-Hotel.

The 34 aspect–category columns are:

FACILITIES#CLEANLINESS, FACILITIES#COMFORT, …, SERVICE#GENERAL

(each value: 0=absent, 1=positive, 2=negative, 3=neutral)

Usage

from datasets import load_dataset

ds = load_dataset("visolex/vlsp2018-absa-hotel")

train = ds.filter(lambda ex: ex["type"] == "train")
val   = ds.filter(lambda ex: ex["type"] == "dev")
test  = ds.filter(lambda ex: ex["type"] == "test")

print(train[0])
