The selection process for Civil Servant Candidates is a critical stage in civil servant management, as it has long-term implications for organizational effectiveness. With the advancement of digital technology, the Indonesian government has implemented electronic stamps in the civil servant candidate registration process to enhance efficiency and transparency. However, this policy has received various responses from the public, particularly on the social media platform Twitter. Many users express positive opinions regarding the convenience of administrative digitalization, while others report technical issues in using electronic stamps. Therefore, sentiment analysis is needed to understand public responses to this policy. One of the effective methods for sentiment classification is Support Vector Machine (SVM), which can optimally separate positive and negative opinions.

INTRODUCTION  \nThe role of Civil Servants (PNS) is crucial in supporting the country's administration and development. The recruitment process of Civil Servant Candidates (CPNS) is an important stage because it has a long-term impact on the effectiveness of public organizations. Along with the advancement of digital technology, the Indonesian government implemented estamps in the CPNS registration process to increase administrative efficiency and transparency.  \nAlthough the electronic stamps policy aims to increase the transparency and efficiency of CPNS registration, its implementation has triggered various responses on social media, especially Twitter/X. As a platform that represents real-time public discussions, Twitter/X is often used in sentiment analysis studies because it can record opinions along with time and location [1] . According to Katadata, Indonesia is the fourth largest Twitter/X user globally, with 27.5 million users.  \nThe public has expressed various opinions via Twitter/X since the implementation of electronic stamps, ranging from support for digitalization to technical complaints, such as failure to  \naccess and affix electronic stamps. These problems are considered to hinder the registration process and cause losses. Therefore, sentiment analysis is needed to understand the public response, by categorizing opinions into positive and negative sentiments.  \nSentiment analysis is a technique for classifying public opinion into positive or negative sentiment [2] . Research by Herwinsyah and Witanti [3], shows that SVM can classify sentiment related to COVID-19 vaccination with 89% accuracy. Ratino et al. [4], also found that SVM is superior to NaïveIBayes, with accuracies of 80.23% and 78.02%, respectively. Meanwhile, research by Yusupa and Tarigan [5] showed that SVM is quite reliable in analyzing public sentiment towards electric vehicles in Indonesia, with an accuracy of 75.62% .  \nThis research was conducted to develop an effective classification model utilizing the ","cbCailCPTDcw851M","https://ap.wps.com/l/cbCailCPTDcw851M","pdf",341809,"English","# Introduction\n# Theoretical Framework\n## Sentiment Analysis Concepts\n## Text Mining and Preprocessing\n## Feature Selection for Text Classification","[{\"question\":\"Why is sentiment analysis needed for e-stamps policy in CPNS registration?\",\"answer\":\"The e-stamps policy aims to improve efficiency and transparency, but its rollout triggers varied responses on Twitter/X, including positive opinions and technical complaints.
