Mingyuan Ma, Sen Na, Hongyu Wang, Congzhou Chen, Jin Xu

TL;DR
This paper introduces a graph-based, behavior-aware recommendation system for interactive news that considers multiple user behaviors and interest concentration to improve personalization and diversity.
Contribution
It proposes a novel multi-behavior graph construction and learning mechanism, integrating behavior types and interest concentration features for enhanced news recommendation.
Findings
Effective modeling of multiple user behaviors improves recommendation accuracy.
Incorporating interest concentration features balances accuracy and diversity.
The system outperforms existing methods on benchmark datasets.
Abstract
Interactive news recommendation has been launched and attracted much attention recently. In this scenario, user's behavior evolves from single click behavior to multiple behaviors including like, comment, share etc. However, most of the existing methods still use single click behavior as the unique criterion of judging user's preferences. Further, although heterogeneous graphs have been applied in different areas, a proper way to construct a heterogeneous graph for interactive news data with an appropriate learning mechanism on it is still desired. To address the above concerns, we propose a graph-based behavior-aware network, which simultaneously considers six different types of behaviors as well as user's demand on the news diversity. We have three main steps. First, we build an interaction behavior graph for multi-level and multi-category data. Second, we apply DeepWalk on the…
