Sports AI hits 81.82% Accuracy Rate for the World Cup Knockout

‘Sports AI’, an artificial intelligence (AI)-based soccer game analysis system, boasted a high hit rate at the 2022 FIFA Qatar World Cup.

On the 20th, according to ‘Fact Plus’ that developed Sports AI, the hit rate of the tournament (excluding the draw) reached 81.82%. The draw was excluded because there was no prediction of a draw in the AI system. However, when the sum of indicators of the two teams is similar and the prediction accuracy is 'very low' or 'low', it can be interpreted as meaning that the probability of a draw is high.

Sports AI predicts wins and losses based on three indicators: recent performance, team history, and professional site evaluation that are derived by analyzing data collected from world's leading soccer-related sites (League, team, player-related information, etc.). It predicts not only wins and losses but also total expected goals of games. The main analysis targets are the five major European football leagues, the UEFA Champions League, the Europa League, and various A matches.

Sports AI's overall hit rate for the Qatar World Cup (excluding draws) was 61.22% (55.26% in the group stage and 81.82% in the knockout). In particular, the hit rate of the round of 16 was 100 percent. The results of the two semifinal matches and the third and fourth place matches, as well as the total expected goals, were all perfectly predicted. It predicted Argentina's slight advantage in the finals, but also saw a high possibility of overtime and penalty shootouts. This turned out to be accurate, and the total expected goal was also perfectly predicted with 3 to 4 goals in 90 minutes.

Sports AI, which proved its analytical ability through the Qatar World Cup, will be deployed for the five major European leagues and European matches that will resume on the 26th. The Champions League hit rate has reached 69.30% (327 games) in the past three seasons.


스포츠 AI, 월드컵 토너먼트 16경기 적중률 81.82%

인공지능(AI) 기반 축구 경기 분석 시스템 ‘스포츠AI’가 2022 국제축구연맹(FIFA) 카타르 월드컵에서 높은 적중률을 자랑했다.

20일 스포츠AI를 개발한 ‘팩트플러스’에 따르면 이번 월드컵의 토너먼트 적중률(무승부 제외)은 81.82%에 달했다. 무승부가제외된 이유는 AI 시스템에서 무승부 예측이 없기 때문이다. 다만 양 팀의 지표 합이 엇비슷하고 예측 정확도가 ‘매우 낮음’ 또는‘낮음’일 때는 무승부 확률이 높다는 의미로 해석할 수 있다.

스포츠AI는 세계 유수 축구 관련 사이트에서 수집한 데이터를 분석해 도출한 최근 경기력, 팀 전력, 전문 사이트 평가 등 3가지지표를 토대로 승패를 점친다. 승패뿐 아니라 해당 경기의 예상 득점까지 예측한다. 주요 분석 대상은 유럽 축구 5대 리그와 유럽축구연맹(UEFA) 챔피언스리그, 유로파리그, 각종 A매치 등이다.

스포츠AI의 카타르 월드컵 전체 적중률은 61.22%였다. 조별리그는 55.26%, 토너먼트는 81.82%로 나타났다. 그중 16강 적중률은 100%에 빛났다. 준결승전 2경기와 3·4위전은 결과는 물론 총 예상 골 수까지 모두 맞췄다. 결승전에서는 아르헨티나의근소한 우위를 점치면서도 연장전과 승부차기 가능성도 높게 봤다. 예상 골 수 역시 90분 기준 3~4골로 완벽했다.

카타르 월드컵을 통해 분석력을 입증한 스포츠AI는 26일 재개되는 유럽 5대 리그와 유럽 대항전에 투입된다. 챔피언스리그 적중률은 지난 세 시즌에 69.30%(327경기)를 기록했다.
