Twitter is a social media platform bridging most countries and allows real-time news discovery. Since the tweets on Twitter are usually short and express public feelings, thus provide a source for opinion mining and sentiment analysis for global events. This paper proposed an effective solution, in providing a sentiment on tweets related to the FIFA World Cup. At least 130k tweets, as the first in the community, are collected and implemented as a dataset to evaluate the performance of the proposed machine learning solution. These tweets are collected with the related hashtags and keywords of the Qatar World Cup 2022. The Vader algorithm is used in this paper for sentiment analysis. Through the machine learning method and collected Twitter tweets, we discovered the sentiments and fun facts of several aspects important to the period before the World Cup. The result shows people are positive to the opening of the World Cup.

Korea plans to have 30 percent of local companies adopt artificial intelligence (AI) technologies by 2030 to beef up competitiveness of local industries, the industry ministry said Friday.

Argentina take on France in the final of World Cup 2022. Kashef, our artificial intelligence (AI) robot, has analysed more than 200 metrics, including the number of wins, goals scored and FIFA rankings, from matches played over the past century to see who is most likely to win on Sunday. Prediction: With 63 matches completed, Kashef has a 68 percent accuracy level. Sizing up all the odds, it could not be any closer. Kashef predicts that France, captained by Hugo Lloris, will edge out Argentina on Sunday to win the 2022 World Cup.

Croatia take on Morocco for the third-place playoff at World Cup 2022. Saturday's game will be the second encounter between the Atlas Lions and 2018 runners-up at this year's World Cup in Qatar. Their opening group match ended in a goalless draw. Kashef, our artificial intelligence (AI) robot, has analysed more than 200 metrics, including the number of wins, goals scored and FIFA rankings, from matches played over the past century to see who is most likely to win on Saturday. Prediction: Morocco's dreams of reaching the World Cup final were dashed after a 2-0 loss to France in the semifinal.

The second day of the World Cup 2022 semifinals will pit two-time champions and holders France against Morocco. Kashef, our artificial intelligence (AI) robot, has analysed more than 200 metrics, including the number of wins, goals scored and FIFA rankings, from matches played over the past century to see who is most likely to win on Wednesday. Morocco are currently unbeaten in this tournament and have stunned the footballing world – not once or twice but three times – by beating Belgium, Spain and Portugal. On every occasion, Kashef was left stunned. The only remaining Arab and African team are now just two wins away from lifting the World Cup trophy.

Argentina take on Croatia in the first semifinal of World Cup 2022. Kashef, our artificial intelligence (AI) robot, has analysed more than 200 metrics, including the number of wins, goals scored and FIFA rankings, from matches played over the past century to see who is most likely to win on Tuesday. Croatia's quarterfinal win over Brazil on December 9 not only stunned the footballing world, but it also flummoxed Kashef – only for a moment, though. Our robot correctly predicted Argentina's victory over the Netherlands on Friday, the second quarterfinal of the Qatar 2022 World Cup. Prediction: Lionel Messi will attempt to guide Argentina into the final for the second time in eight years against 2018 World Cup runners-up Croatia.

Historians will argue that other matches in World Cup history were dirtier. Think'The Battle of Santiago' in 1962, in which Chile and Italy brawled throughout and which the BBC's David Coleman described as "the most stupid, appalling, disgusting and disgraceful exhibition of football in the history of the game".

Qatar's World Cup has seen the round-of-16 games. Now, it is time for the quarter-finals. Among the biggest shocks during the World Cup this year have been the games that former champions – Brazil, Spain, Argentina and Germany – did not win. This tournament also saw teams playing for Africa, Asia, and North America represented in the round of 16 along with traditional football powerhouses South America and Europe. But behind the great football spectacle, there has been a battle taking place at the Al Jazeera offices.

The last round-of-16 match at the World Cup 2022 will pit ninth-ranked Portugal against 15th-ranked Switzerland. Kashef, our artificial intelligence (AI) robot, has analysed more than 200 metrics, including the number of wins, goals scored and FIFA rankings, from matches played over the past century to see who is most likely to win today. Prediction: Portugal and Switzerland are fairly evenly matched. The two European teams have already faced each other twice this year in the Nations League, winning one game apiece. Portugal topped their group, scoring six goals across three matches.

Japan take on Croatia in the round-of-16 match at the World Cup 2022 on Monday. Kashef, our artificial intelligence (AI) robot, has analysed more than 200 metrics, including the number of wins, goals scored and FIFA rankings, from matches played over the past century to see who is most likely to win. Prediction: Japan have not been easy to predict so far in this tournament. The 24th-ranked side stunned Germany (11th) in their first match, then lost to Costa Rica (31st), before pulling off another major upset by beating Spain (seventh). Croatia, who mixed two 0-0 draws with a 4-1 thrashing of Canada in the group stage, have reached the last 16 twice in five previous World Cup appearances.
