Bengali Fake Review Detection (BFRD) dataset
收藏Bengali Fake Reviews: A Benchmark Dataset and Detection System
数据集概述
- 名称:Bengali Fake Review Detection (BFRD) 数据集
- 描述:这是首个公开可用的用于识别孟加拉语虚假评论的数据集,包含7710条非虚假和1339条虚假的与食品相关的评论,收集自社交媒体帖子。
- 数据处理:提出了一种独特的管道,将英语单词翻译成相应的孟加拉语含义,并将罗马化的孟加拉语回译为孟加拉语。
- 模型开发:使用多种深度学习和预训练的转换器语言模型进行了严格的实验,最终提出了一种结合四个预训练转换器的加权集成模型:BanglaBERT, BanglaBERT Base, BanglaBERT Large 和 BanglaBERT Generator。
数据集结构
- 代码:包含深度学习模型、转换器、集成模型和文本转换管道的所有代码。
- 数据集:包含两个Excel文件,分别是
fake.xlsx和non-fake.xlsx,每个文件包含两列:Review(收集的原始评论)和 Label(标注)。
数据集统计
- 标注:由4位母语为孟加拉语的说话者标注,信任度得分超过90%。
- Fleiss Kappa 得分:0.83

Such reviews can deceive customers and cause damage to the reputation of products or services, making it crucial to identify them. Although the detection of fake reviews has been extensively studied in English language, detecting fake reviews in non-English languages such as Bengali is still a relatively unexplored research area. The novelty of the study unfolds on three fronts: (i) a new publicly available dataset called Bengali Fake Review Detection (BFRD) dataset is introduced, (ii) a unique pipeline has been proposed that translates English words to their corresponding Bengali meaning and also back transliterates Romanized Bengali to Bengali, (iii) a weighted ensemble model that combines four pre-trained transformers model is proposed. The developed dataset consists of 7710 non-fake and 1339 fake food-related reviews collected from social media posts. Rigorous experiments have been conducted to compare multiple deep learning and pre-trained transformer language models and our proposed model to identify the best-performing model. According to the experimental results, the proposed ensemble model attained a weighted F1-score of 0.9843 on a dataset of 13,390 reviews, comprising 1339 actual fake reviews, 5,356 augmented fake reviews, and 6695 reviews randomly selected from the 7710 non-fake instances.} }
