Social network games, nested on the platform of social networking sites, have become a new fa-vorite of college students. And college students′Internet addiction has been of considerable interest to the academia in recent years. The reasons why college students participate in social network games are ex-plored. A number of questionnaires are distributed through the Internet to collect information which needs to convert to data format and import into Waikato Environment for Knowledge Analysis ( WEKA) . And the decision tree model is obtained via the J48 decision tree algorithm. The results of the experiment indicate that college students′ social network game behavior is mainly related to family environment, living condi-tions and social networking sites activeness. The integrity and happiness degree of a family, together with college students′attitude towards life and social networking sites activeness, are all important causes in so-cial network game behavior. In addition, college students should be provided with effective strategies to prevent Internet game addiction because the reason of the participation is partly coincident with that of the Internet addiction of college students.%随着SNS社交网站的发展,嵌套在其平台上的社交网络游戏已成为大学生的新宠,而大学生网络成瘾也成为社会各界关注的焦点.为研究大学生参与社交网络游戏的原因,本文通过网络发布问卷的方式对大学生参与社交网络游戏的情况进行调查,将收集到的信息转换成数据导入到数据挖掘软件WEKA中.采用J48决策树算法对数据进行分类处理,得到游戏参与情况的决策树模型.模型分析结果表明,大学生社交网络游戏玩家参与社交网络游戏的原因主要与家庭环境、生活状态以及网站的社交活性有关.家庭的完整性和幸福度是影响大学生参与SNS网络游戏的最重要原因之一,对待生活的心态同样影响大学生是否会选择参与社交网络游戏,而SNS网络广泛的社交性是促进大学生参与社交网络游戏的另一个重要原因.这些参与游戏的原因与大学生网络成瘾的原因部分重合,为预防大学生网络成瘾提供了依据.
