Despite growing research, several critical gaps remain in citation recommendation: (i) heterogeneous relations are underutilized, limiting the ability to model complex interactions; (ii) temporal dynamics and real-time updates are rarely incorporated, restricting adaptivity; (iii) social and serendipity signals (e.g., co-reading, communities, novelty\/diversity) are largely neglected, reducing user-centric utility; (iv) cross-lingual and cross-domain transfer is underexplored, limiting global applicability; and (v) evaluation practices remain fragmented, emphasizing accuracy over transparency, diversity, and robustness. We consolidate datasets, tasks, and metrics, and outline a roadmap emphasizing relation-weighted heterogeneous graphs, temporally adaptive learners, cross-lingual alignment, explanation-aware objectives, and deployable pipelines with open artifacts. This graph-centric perspective surfaces actionable gaps and opportunities for building citation recommenders that are accurate, transparent, and production-ready.\n                  <\/jats:p>","DOI":"10.1007\/s42979-026-04848-2","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T11:36:31Z","timestamp":1773056191000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Critical Review on Citation Recommendation Systems Through a Graph-Centric Approach"],"prefix":"10.1007","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7197-1416","authenticated-orcid":false,"given":"Pavlos","family":"Kefalas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6404-645X","authenticated-orcid":false,"given":"Zafar","family":"Ali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4026-4329","authenticated-orcid":false,"given":"Yannis","family":"Manolopoulos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,3,9]]},"reference":[{"issue":"6","key":"4848_CR1","doi-asserted-by":"publisher","first-page":"734","DOI":"10.1109\/TKDE.2005.99","volume":"17","author":"G Adomavicius","year":"2005","unstructured":"Adomavicius G, Tuzhilin A.
