摘要: Trending topics represent the that are becoming increasingly popular and attract a sudden spike in human attention. critical useful modern search engines, which can not only enhance user engagements but also improve experiences. Large volumes of queries over time indicative aggregated interests thus provide rich information for detecting trending topics. The derived from query logs be naturally treated as temporal correlation network, suggesting both local global signals. signals trending/non-trending within each frequency sequence, denote relationships across sequences. We hypothesize integrating benefit topic detection. In an attempt to jointly exploit complementary networks, we propose novel framework, Local-Global Ranking (LGRank), capture sequence representation with adversarial learning model correlations simultaneously experimental results on real-world datasets commercial engine demonstrate effectiveness LGRank
