The main contributions of this project are:

1.  The creation of the first annotated dataset for sentiment analysis in the Uzbek language, obtained from reviews of the top 100 Google Play Store applications used in Uzbekistan.  This manually annotated dataset contains  2500  positive and  1800  negative reviews. Furthermore, we have also built a larger dataset by automatically translating (using Google Translate API) an existing  English dataset of application reviews. The translated dataset has≈10K positive and≈10K negative app reviews, after manually eliminating the major machine translation errors by either correcting or removing them completely.

2.  The definition of the baselines for sentiment analyses in Uzbek by considering both traditional machine learning methods as well as recent deep learning techniques fed  with  fastText pre-trained word  embeddings. Although all the tested models are relatively accurate and differences between models are small, the neural network models tested do not manage tosubstantially outperform traditional models.  We believe that the quality of currently available pre-trained word embeddings for Uzbek is not enough to let deep learning models perform at their full potential.
