Existing methods model item transitions through leveraging sequential patterns. However, they mainly consider the target user\u2019s behaviours and dynamic characteristics, while often ignoring high-order collaborative connections when modelling user preferences. Some recent works try to use graph-based methods to introduce high-order collaborative signals for sequential recommendation. However, these methods are flawed by two problems: the sequential patterns cannot be effectively mined and their way of introducing high-order collaborative signals is not suitable for sequential recommendation. To address these problems, we propose to fully exploit sequence features and model high-order collaborative signals for sequential recommendation. We propose a\n            <jats:bold>N<\/jats:bold>\n            eighbor user\n            <jats:bold>I<\/jats:bold>\n            ntention-based\n            <jats:bold>S<\/jats:bold>\n            equential\n            <jats:bold>Rec<\/jats:bold>\n            ommender (NISRec), which utilizes the intentions of high-order connected neighbor users as high-order collaborative signals in order to improve recommendation performance for the target user. The NISRec contains two main modules: the neighbor user intention embedding module (NIE) and the fusion module. The NIE module describes both the long-term and short-term intentions of neighbor users and aggregates them separately. The fusion module uses these two types of aggregated intentions to model high-order collaborative signals in both the embedding process and user preference modelling phase for recommendations of the target user. Experimental results show that our new approach outperforms the state-of-the-art methods on both sparse and dense datasets. Extensive studies further show the effectiveness of the diverse neighbor intentions introduced by the NISRec.\n          <\/jats:p>","DOI":"10.1145\/3580520","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T12:29:35Z","timestamp":1675254575000},"page":"1-28","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Learning Neighbor User Intention on User\u2013Item Interaction Graphs for Better Sequential Recommendation"],"prefix":"10.1145","volume":"18","author":[{"given":"Mei","family":"Yu","sequence":"first","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Kun","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Mankun","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Jian","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Tianyi","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Di","family":"Jin","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Xuewei","family":"Li","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]},{"given":"Ruiguo","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Intelligence and Computing, TianJin University, Tianjin, China, Tianjin Key Laboratory of Advanced Networking, Tianjin, China, and Tianjin Key Laboratory of Cognitive Computing and Application, Tianjin, China"}]}],"member":"320","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1145\/3404835.3462832"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/3159652.3159668"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.24963\/ijcai.2018\/462"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSMC.2017.2777889"},{"key":"e_1_3_2_6_2","first-page":"4171","volume-title":"Proceedings of the 2019 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies","author":"Devlin Jacob","year":"2019","unstructured":"Jacob Devlin, Ming-Wei Chang, Kenton Lee, and Kristina Toutanova. 2019.
