It is challenging because DDIs are related to multiple factors, such as genes, drug molecular structure, diseases, biological processes, side effects, etc. It is a crucial technology for Knowledge graph to present multi-relation among entities. Recently some existing graph-based computation models have been proposed for DDIs prediction and get good performance. However, there are still some challenges in the knowledge graph representation, which can extract rich latent features from drug knowledge graph (KG).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>In this work, we propose a novel multi-view feature representation and fusion (MuFRF) architecture to realize DDIs prediction. It consists of two views of feature representation and a multi-level latent feature fusion. For the feature representation from the graph view and KG view, we use graph isomorphism network to map drug molecular structures and use RotatE to implement the vector representation on bio-medical knowledge graph, respectively. We design concatenate-level and scalar-level strategies in the multi-level latent feature fusion to capture latent features from drug molecular structure information and semantic features from bio-medical KG. And the multi-head attention mechanism achieves the optimization of features on binary and multi-class classification tasks. We evaluate our proposed method based on two open datasets in the experiments. Experiments indicate that MuFRF outperforms the classic and state-of-the-art models.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Our proposed model can fully exploit and integrate the latent feature from the drug molecular structure graph (graph view) and rich bio-medical knowledge graph (KG view). We find that a multi-view feature representation and fusion model can accurately predict DDIs. It may contribute to providing with some guidance for research and validation for discovering novel DDIs.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12859-023-05212-4","type":"journal-article","created":{"date-parts":[[2023,3,14]],"date-time":"2023-03-14T13:03:25Z","timestamp":1678799005000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Multi-view feature representation and fusion for drug-drug interactions prediction"],"prefix":"10.1186","volume":"24","author":[{"given":"Jing","family":"Wang","sequence":"first","affiliation":[]},{"given":"Shuo","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Runzhi","family":"Li","sequence":"additional","affiliation":[]},{"given":"Gang","family":"Chen","sequence":"additional","affiliation":[]},{"given":"Siyu","family":"Yan","sequence":"additional","affiliation":[]},{"given":"Lihong","family":"Ma","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2023,3,14]]},"reference":[{"key":"5212_CR1","doi-asserted-by":"publisher","first-page":"975","DOI":"10.1038\/446975a","volume":"446","author":"KM Giacomini","year":"2007","unstructured":"Giacomini KM, Krauss RM, Roden DM, Eichelbaum M, Hayden MR, Nakamura Y.
