论文摘要

患者和看护人对在线社区对医疗保健信息的依赖越来越多,导致错误信息或主观,轶事和不准确或非特异性建议的扩散增加,如果采取行动,可能会对患者造成严重伤害。因此,迫切需要及时将用户与准确量身定制的健康信息联系起来,以防止这种伤害。本文提出了一种创新的方法,以向在线社区的参与者提出可靠的信息,因为他们在其疾病或治疗中的不同阶段移动。我们假设具有相似疾病进展或治疗过程的患者在可比的阶段会有相似的信息需求。具体来说,我们提出了预测主题标签或关键字的问题,这些问题是根据用户的个人资料,社区内的在线互动的痕迹(过去的帖子,答复)以及其他用户的概况和痕迹,这些用户的在线互动的痕迹以及与目标用户相似的其他配置文件和相似互动的痕迹的概况和痕迹。结果是针对在线健康社区用户需求量身定制的协作信息过滤或推荐系统的变体。我们在专家策划的数据集上报告了实验的结果,该数据表明,相对于对主题标签的准确预测(以及感兴趣的信息来源),提出的方法比最先进的基线的状态相比具有优越性。

The increasing reliance on online communities for healthcare information by patients and caregivers has led to the increase in the spread of misinformation, or subjective, anecdotal and inaccurate or non-specific recommendations, which, if acted on, could cause serious harm to the patients. Hence, there is an urgent need to connect users with accurate and tailored health information in a timely manner to prevent such harm. This paper proposes an innovative approach to suggesting reliable information to participants in online communities as they move through different stages in their disease or treatment. We hypothesize that patients with similar histories of disease progression or course of treatment would have similar information needs at comparable stages. Specifically, we pose the problem of predicting topic tags or keywords that describe the future information needs of users based on their profiles, traces of their online interactions within the community (past posts, replies) and the profiles and traces of online interactions of other users with similar profiles and similar traces of past interaction with the target users. The result is a variant of the collaborative information filtering or recommendation system tailored to the needs of users of online health communities. We report results of our experiments on an expert curated data set which demonstrate the superiority of the proposed approach over the state of the art baselines with respect to accurate and timely prediction of topic tags (and hence information sources of interest).
