The large volumes of social media information such as investment reviews that delegate emotion-driven factors, together with price technical indicators formulate a \u201csnapshot\u201d of the evolving stock market profile. However, previous studies usually model the temporal trajectories of price and media modalities separately while losing their interrelated influences. Moreover, they mainly extract review semantics via sequential or attentive models, whereas the rich text associated knowledge is largely neglected. In this paper, we propose a novel heterogeneous interactive snapshot network for stock profiling and recommendation. We model investment reviews in each snapshot as a heterogeneous document graph, and develop a flexible hierarchical attentive propagation framework to capture fine-grained proximity features. Further, to learn stock embedding for ranking, we introduce a novel twins-GRU method, which tightly couples the media and price parallel sequences in a cross-interactive fashion to catch dynamic dependencies between successive snapshots. Our approach excels state-of-the-arts over 7.6% in terms of cumulative and risk-adjusted returns in trading simulations on both English and Chinese benchmarks.<\/jats:p>","DOI":"10.24963\/ijcai.2022\/550","type":"proceedings-article","created":{"date-parts":[[2022,7,15]],"date-time":"2022-07-15T22:55:56Z","timestamp":1657925756000},"page":"3962-3969","source":"Crossref","is-referenced-by-count":8,"title":["Heterogeneous Interactive Snapshot Network for Review-Enhanced Stock Profiling and Recommendation"],"prefix":"10.24963","author":[{"given":"Heyuan","family":"Wang","sequence":"first","affiliation":[{"name":"School of Computer Science, National Engineering Laboratory for Big Data Analysis and Applications, Peking University, China"},{"name":"Institute of Computational Social Science, Peking University (Qingdao)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tengjiao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science, National Engineering Laboratory for Big Data Analysis and Applications, Peking University, China"},{"name":"Institute of Computational Social Science, Peking University (Qingdao)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shun","family":"Li","sequence":"additional","affiliation":[{"name":"University of International Relations"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shijie","family":"Guan","sequence":"additional","affiliation":[{"name":"School of Computer Science, National Engineering Laboratory for Big Data Analysis and Applications, Peking University, China"},{"name":"Institute of Computational Social Science, Peking University (Qingdao)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayi","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Computer Science, National Engineering Laboratory for Big Data Analysis and Applications, Peking University, China"},{"name":"Institute of Computational Social Science, Peking University (Qingdao)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Computer Science, National Engineering Laboratory for Big Data Analysis and Applications, Peking University, China"},{"name":"Institute of Computational Social Science, Peking University (Qingdao)"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10584","event":{"name":"Thirty-First International Joint Conference on Artificial Intelligence {IJCAI-22}","theme":"Artificial Intelligence","location":"Vienna, Austria","acronym":"IJCAI-2022","number":"31","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2022,7,23]]},"end":{"date-parts":[[2022,7,29]]}},"container-title":["Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2022,7,18]],"date-time":"2022-07-18T07:10:19Z","timestamp":1658128219000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2022\/550"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2022,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2022\/550","relation":{},"subject":[],"published":{"date-parts":[[2022,7]]}}}
