Users\u2019 curiosities highly affect the recommendation accuracy and the effectiveness of explanations. Different target users have different levels of curiosities, while the curiosity of the same user changes dynamically. However, existing techniques cannot capture users\u2019 dynamic curiosities from the historical user-item interactions for effective explainable recommendation.

Specifically, we first propose a novel multi-view representation learning to model the temporal user-item interactions. Then, we propose a new curiosity-enhanced recommendation to dynamically capture users\u2019 curiosities, which improves the recommendation quality in a mutual promotion manner. Finally, we propose an adaptive rule-guided hybrid explanation generation strategy that enables more personalized explanations and well reflects the users\u2019 dynamic psychological states behind the transactions. The experimental results demonstrate the high effectiveness of our proposed model.\n                  <\/jats:p>","DOI":"10.1145\/3745774","type":"journal-article","created":{"date-parts":[[2025,6,23]],"date-time":"2025-06-23T05:37:00Z","timestamp":1750657020000},"page":"1-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Curious or Conservative: Dynamic Curiosity-aware Explainable Recommendation"],"prefix":"10.1145","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5307-4893","authenticated-orcid":false,"given":"Yue","family":"Kou","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, Northeastern University","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3314-7124","authenticated-orcid":false,"given":"Dong","family":"Li","sequence":"additional","affiliation":[{"name":"College of Information, Liaoning University","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0310-6372","authenticated-orcid":false,"given":"Derong","family":"Shen","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Northeastern University","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1302-818X","authenticated-orcid":false,"given":"Xiangmin","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Computing Technologies, RMIT University","place":["Melbourne, Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0166-1324","authenticated-orcid":false,"given":"Tiezheng","family":"Nie","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Northeastern University","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3171-8889","authenticated-orcid":false,"given":"Ge","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Northeastern University","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2025,11,22]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijhcs.2013.12.007"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/3018661.3018686"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2022.3146178"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2019.2906190"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1145\/3038912.3052569"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1145\/2600428.2609579"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1145\/3077136.3080822"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1145\/3340531.3411992"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1145\/3366423.3380164"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1145\/3209978.3210010"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/ICDE51399.2021.00137"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1145\/3485447.3512029"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1145\/3483611"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.24963\/ijcai.2019\/296"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-73200-4_10"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1145\/3397271.3401171"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1145\/3447548.3467315"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1145\/3437963.3441762"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1145\/3580488"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.18653\/v1\/2024.findings-emnlp.22"},{"key":"e_1_3_2_22_2","first-page":"1257","volume-title":"Proceedings of the NIPS","author":"Salakhutdinov Ruslan","year":"2007","unstructured":"Ruslan Salakhutdinov and Andriy Mnih. 2007.
