论文摘要
鉴于用户的历史互动序列,在线小说推荐表明,用户可能感兴趣的下一部小说。在线小说推荐很重要,但却毫无疑问。在本文中,我们专注于向在线小说阅读平台的新用户推荐在线小说,该平台首次访问该平台发生在过去的七天内。我们对新用户的在线小说推荐有两个观察。首先,重复对新用户的新颖消费是一种普遍现象。其次,用户和小说之间的互动是有益的。为了准确预测用户是否会重新征服小说,至关重要的是要在细粒度的水平上表征每种相互作用。基于这两个观察结果,我们提出了一个神经网络,用于在线小说推荐,称为NovelNet。 Novelnet可以同时推荐用户消费的小说和新小说的下一部小说。具体而言,相互作用编码器用于获得相互作用的细粒度属性的准确相互作用表示,并且将具有点损失的指针网络纳入NovelNet中,以推荐先前消耗的小说。此外,一个在线小说推荐数据集是由著名的在线小说阅读平台构建的,并作为基准发布而发布。数据集上的实验结果证明了NovelNet的有效性。
Given a user's historical interaction sequence, online novel recommendation suggests the next novel the user may be interested in. Online novel recommendation is important but underexplored. In this paper, we concentrate on recommending online novels to new users of an online novel reading platform, whose first visits to the platform occurred in the last seven days. We have two observations about online novel recommendation for new users. First, repeat novel consumption of new users is a common phenomenon. Second, interactions between users and novels are informative. To accurately predict whether a user will reconsume a novel, it is crucial to characterize each interaction at a fine-grained level. Based on these two observations, we propose a neural network for online novel recommendation, called NovelNet. NovelNet can recommend the next novel from both the user's consumed novels and new novels simultaneously. Specifically, an interaction encoder is used to obtain accurate interaction representation considering fine-grained attributes of interaction, and a pointer network with a pointwise loss is incorporated into NovelNet to recommend previously-consumed novels. Moreover, an online novel recommendation dataset is built from a well-known online novel reading platform and is released for public use as a benchmark. Experimental results on the dataset demonstrate the effectiveness of NovelNet.
