In this paper, we propose an effective method to block illegal gambling advertisement on social media. With the increase of smartphone and internet usage, users can easily access various information while sharing information such as text and video with a large number of others. In addition, illegal sports gambling advertisements are also continue to be transmitted on SNS. To avoid most surveillance networks, users are easily exposed to illegal sports gambling advertisement images by including phrases in the images that indicate illegal sports gambling advertisements. In order to cope with these problems, we proposed a method to actively block illegal sports gambling advertisements in a way different from the conventional passive methods. In this paper, we select words frequently used for illegal sports gambling, classifies them into three groups according to their importance, calculate WF for each word using weighted formula by degree of relevance and frequency, and then sum the WF of the words in the image. Blocking, warning, and passing were determined by cv, the total of WF. Experimenting with the proposed method, 193 out of 200 experimental images were correctly judged with 96.5% accuracy, and even though 7 images were illegal sports gambling advertisements. Further research is needed to block 3.5% of illegal sports betting ads that cannot be blocked in the future.

The previous researches of gambling have been rather focused on the legal gambling industry and gambling addiction and ignored the issue of illegal gambling. But, illegal gambling in Korea has been continuously growing in its volume and the numbers of the relevant mental and social problems such as gambling addiction, crimes, suicides, and etc. have been increasing rapidly. The present study investigated the psychological characteristics of illegal gamblers with comparing gamblers who never experienced illegal gambling (NE), who experienced illegal gambling but participate mainly in legal gambling (EIG), and who participate mainly in illegal gambling (MIG). 1317 NEs, 177 EIGs, and 37 MIGs were recruited and completed an online survey that measured individual dispositions (risk-taking tendency, regulatory focus, locus of control), attitudes towards gambling regulations, misconception of illegal gambling, motives (monetary, excitement, socialization), and emotions. First, EIGs and MIGs, compared to NEs, preferred risk-taking, and EIGs were more promotion focused than NEs. Also, EIGs perceived illegal gambling as less illegal and tended to hold more misconceptions about illegal gambling, compared to NEs. Furthermore, EIGs and MIGs had stronger monetary and excitement motivation than NEs. Finally, MIGs were more likely to feel anxious than other groups. Focusing on the illegality of gambling, the characteristics of illegal gamblers are discussed and political implication on illegal gambling is suggested.

The Horse race industry has the largest proportion of the domestic legal gambling industry. However, there is limited statistical analysis on horse races versus other sports. We propose prediction models for winning horses in horse races using data mining techniques such as logistic regression, linear regression, and random forest. Horse races data are from the Korea Racing Authority and we use horse racing reports, information of racehorses, jockeys, and horse trainers. We consider two models based on ranks and time records. The analysis results show that prediction of ranks is affected by information on racehorses, number of wins of racehorses and jockeys. We place wagers for the last month of races based on our prediction models that produce serious profits.
