Considerations for Using the Data

Social Impact of Dataset

The author's research has tackled a highly important task of sentiment analysis for Arabic language in the Lebanese context on 3916 reviews’ services from Google and Zomato. Experiments show three main findings:

  1. The classifier is confident when used to predict positive reviews,
  2. while it is biased on predicting reviews with negative sentiment, and finally
  3. the low percentage of negative reviews in the corpus contributes to the diffidence of LR.
