Introduction to Aspect-Based Sentiment Analysis

In today's digital age, online educational platforms have become increasingly popular, providing students with various learning resources that can be easily accessed. One such platform is Zenius, which has gained widespread use among students. As the application's popularity grows, users often provide reviews that include positive and negative opinions regarding its performance. Understanding these opinions is crucial for companies to evaluate and improve the application's performance. This study aims to extract valuable information from user sentiment based on each aspect of reviews, making it easier to understand.

The Importance of Sentiment Analysis in Educational Platforms

Sentiment analysis is a crucial aspect of understanding user opinions and experiences. By analyzing user reviews, companies can identify areas of improvement, leading to better services and a more satisfying user experience. In the context of educational platforms like Zenius, sentiment analysis can help developers identify areas that need improvement, such as features, content quality, price, user interface, and customer support. This information can be used to enhance the overall learning experience for users.

Methodology: Data Collection and Preprocessing

This study used a total of 1500 review data taken from the results of the Google Play Store scraping. The first stage carried out was to clean the data through the preprocessing process. This process is very crucial to ensure that the data used in the analysis is relevant and clean of noise which can affect the results of the analysis. The preprocessing process involved removing unnecessary characters, punctuation, and special characters, as well as converting all text to lowercase.

TF-IdF Method: Assigning Weights to Words

After the cleaning process, each word in the review was given a weight using the TF-IdF (Terquency-Inverse Document Frequency) method. This method helps in assessing how important a word in the context of documents and dataset as a whole. In this way, words that often arise but do not provide information that means can be minimized, while words that are rare but significant still get attention. The TF-IdF method is a widely used technique in natural language processing (NLP) for text analysis.

Aspect-Based Sentiment Analysis Using the Naïve Bayes Algorithm

Aspect-based sentiment analysis was carried out using the Naïve Bayes complement algorithm. This algorithm was chosen because of its effectiveness in overcoming unbalanced data, which often occurs in user review data. With this algorithm, researchers can classify sentiments into various aspects related to Zenius applications, such as features, content quality, price, user interface, and customer support. The Naïve Bayes algorithm is a popular machine learning algorithm used for sentiment analysis and text classification.

Evaluation Results: Confusion Matrix and Accuracy

The evaluation results of this study are presented in the form of a confusion matrix, which shows the classification performance of the algorithm used. From the analysis conducted, an average accuracy of 80% was obtained based on five aspects of the product. This shows that the Naïve Bayes Complement Algorithm is effective in classifying user sentiment and providing useful insights for developers to better understand user experiences. The confusion matrix is a widely used evaluation metric in machine learning and NLP.

Conclusion and Future Directions

Overall, this study made a significant contribution in understanding user sentiment to the Zenius application. By knowing the aspects that need to be improved, Zenius can improve the quality of its services and provide a better learning experience for its users. This aspect-based sentiment analysis is not only useful for Zenius, but can also be adopted by other educational platforms to improve user performance and satisfaction. Future studies can explore the application of this methodology to other educational platforms and industries.

Limitations and Future Research Directions

This study has several limitations, including the use of a small dataset and the reliance on a single algorithm for sentiment analysis. Future studies can explore the use of larger datasets and the application of multiple algorithms for sentiment analysis. Additionally, future research can investigate the use of aspect-based sentiment analysis in other industries and applications.

Conclusion

In conclusion, this study demonstrates the effectiveness of the Naïve Bayes algorithm in aspect-based sentiment analysis of user reviews. The study provides valuable insights into the aspects of the Zenius application that need improvement, which can be used to enhance the overall learning experience for users. The methodology used in this study can be adopted by other educational platforms to improve user performance and satisfaction.

Q1: What is sentiment analysis, and why is it important in educational platforms like Zenius?
