Analysis of Football Supporters' Sentiment on Social Media on PSSI's Performance using the K-Nearest Neighbor Method
Bibliographic record
Abstract
The performance of the Football Association of Indonesia (PSSI) often receives public scrutiny, especially from football supporters. The dynamics of Indonesian football, which are frequently colored by controversy, have generated a large number of opinions on social media. This study aims to analyze the sentiment of football supporters on social media regarding PSSI’s performance using the K-Nearest Neighbor (KNN) method. The research data were collected from Twitter through a crawling process, with word weighting performed using the TF-IDF method, while the KNN model was tested with the parameter value of k = 3. The results show that the K-Nearest Neighbor (KNN) model achieved an accuracy of 93.5%, with a precision of 63.2%, recall of 52.9%, and an f1-score of 56.5%. However, the model’s performance was influenced by data imbalance, where neutral sentiment comments were far more dominant than positive or negative ones. The sentiment distribution indicates that public opinion on social media was largely neutral, while the proportion of positive and negative sentiments was relatively smaller. These findings suggest that although criticisms of PSSI’s performance were quite prevalent, most supporters tended to remain neutral in expressing their opinions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
