摘要:

近年来,社区问答(CQA)网站得到了广泛的传播和成倍的增长。像Reddit、Quora和Stack Exchange这样的网站在那些对寻找各种问题答案感兴趣的人中越来越受欢迎。找到这些答案的一种实用方法是根据现有的答案和评论自动预测最佳候选人。许多研究对CQA中的答案预测进行了研究,但对使用问卷的背景信息的关注有限。我们使用一种新的方法来解决这个限制,该方法使用提问者的背景信息和其他特征(如文本内容或与其他参与者的关系)来预测最佳答案。我们的答案分类模型使用Stack Exchange数据集进行训练,并使用曲线下面积(AUC)指标进行验证。实验结果表明,所提出的方法补充了以前的方法,指出用户之间的关系的重要性,特别是在整个参与水平在不同的社区堆栈交换。此外,我们指出,有很少的重叠之间的用户关系信息和信息所表示的浅文本功能和元功能,如时间差。

英文摘要:

Community Question Answering (CQA) sites have spread and multiplied significantly in recent years. Sites like Reddit, Quora, and Stack Exchange are becoming popular amongst people interested in finding answers to diverse questions. One practical way of finding such answers is automatically predicting the best candidate given existing answers and comments. Many studies were conducted on answer prediction in CQA but with limited focus on using the background information of the questionnaires. We address this limitation using a novel method for predicting the best answers using the questioner's background information and other features, such as the textual content or the relationships with other participants. Our answer classification model was trained using the Stack Exchange dataset and validated using the Area Under the Curve (AUC) metric. The experimental results show that the proposed method complements previous methods by pointing out the importance of the relationships between users, particularly throughout the level of involvement in different communities on Stack Exchange. Furthermore, we point out that there is little overlap between user-relation information and the information represented by the shallow text features and the meta-features, such as time differences.
