Discovering what other people think has always been a key aspect of our
information-gathering strategy. People can now actively utilize information
technology to seek out and comprehend the ideas of others, thanks to the
increased availability and popularity of opinion-rich resources such as online
review sites and personal blogs. Because of its crucial function in
understanding people's opinions, sentiment analysis (SA) is a crucial task.
Existing research, on the other hand, is primarily focused on the English
language, with just a small amount of study devoted to low-resource languages.
For sentiment analysis, this work presented a new multi-class Urdu dataset
based on user evaluations. The tweeter website was used to get Urdu dataset.
Our proposed dataset includes 10,000 reviews that have been carefully
classified into two categories by human experts: positive, negative. The
primary purpose of this research is to construct a manually annotated dataset
for Urdu sentiment analysis and to establish the baseline result. Five
different lexicon- and rule-based algorithms including Naivebayes, Stanza,
Textblob, Vader, and Flair are employed and the experimental results show that
Flair with an accuracy of 70% outperforms other tested algorithms.

本研究提出了一个基于用户评价的新型多类乌尔都数据集，旨在为乌尔都情感分析构建手动注释的数据集，并建立基准结果。使用五种不同的词库和基于规则的算法，最终实验结果表明，Flair 的准确率为 70%，优于其他测试的算法。
