| 摘 要： | 针对论文结构特点及对论文快速共享的需求，提出一种基于兴趣点转移的轻量级自适应论文推送模型。模型先定义用户的兴趣点树，采用填表的方法建立用户兴趣点树，在兴趣点树上加入时间因子，以解决用户兴趣转移的问题；再通过挖掘用户阅读行为，不断修正用户的兴趣点树；在推送阶段采用混合过滤算法推送结果。将此模型应用于中国科技论文在线手持终端服务示范平台，并与基于教育背景的协同过滤模型进行推送对比实验，结果表明该模型能有效满足个性化论文快速共享的需求。 |

| Abstract： | According to the paper structure characters and the requirement of paper rapid sharing, this paper proposes a lightweight adaptive push model based on the transmission for points of interest. The model defines the user's point of interest tree to solve the problem of the migration of user interest by filling interest points and adding time factor into the tree. By mining the user reading behaviors, the model constantly revises user's point of interest tree. At the pushing stage, the hybrid filtering pushing algorithm is used to push mixed results. This model is applied to the demonstration platform of Chinese Science Paper Online on handheld terminal services. And by the comparison with the collaborative filtering model based on educational background, the experiments show that the model can effectively meet the needs of personalized paper rapid sharing. |
