Development of two data bases with comments in Bulgarian language and application of supervised learning approaches on them for comparative sentiment analysis. А brief overview
The purpose of the current paper is to make an overview of the work done so far by the authors and make a summary of the results and reflections on the performed sentiment analysis on user comments in two different fields in Bulgarian language. As a starting point for the authors’ work is the development of two databases with users’ reviews and their preprocessing to become usable source of information for different types of analysis projects. As a result of the preprocessing is a revised Bulgarian language-driven algorithm for data preprocessing for Bulgarian language. The second part of the project is implemented into two steps: sentiment analysis using the supervised learning approaches developed for the two databases and a comparative sentiment analysis of the two databases, following their additional examination.
