Existing graph-based models ignore the hierarchical structures of molecules. According to the knowledge of chemistry and pharmacy, the functional groups of molecules are closely related to its physio-chemical properties and binding affinities. So, it should be helpful to represent molecular graphs by fragments that contain functional groups for molecular property prediction.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>In this article, to boost the performance of molecule property prediction, we first propose a definition of molecule graph fragments that may be or contain functional groups, which are relevant to molecular properties, then develop a fragment-oriented multi-scale graph attention network for molecular property prediction, which is called FraGAT. Experiments on several widely used benchmarks are conducted to evaluate FraGAT. Experimental results show that FraGAT achieves state-of-the-art predictive performance in most cases. Furthermore, our case studies show that when the fragments used to represent the molecule graphs contain functional groups, the model can make better predictions. This conforms to our expectation and demonstrates the interpretability of the proposed model.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Availability and implementation<\/jats:title>\n                  <jats:p>The code and data underlying this work are available in GitHub, at https:\/\/github.com\/ZiqiaoZhang\/FraGAT.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Supplementary information<\/jats:title>\n                  <jats:p>Supplementary data are available at Bioinformatics online.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/bioinformatics\/btab195","type":"journal-article","created":{"date-parts":[[2021,3,24]],"date-time":"2021-03-24T12:20:23Z","timestamp":1616588423000},"page":"2981-2987","source":"Crossref","is-referenced-by-count":76,"title":["FraGAT: a fragment-oriented multi-scale graph attention model for molecular property prediction"],"prefix":"10.1093","volume":"37","author":[{"given":"Ziqiao","family":"Zhang","sequence":"first","affiliation":[{"name":"Shanghai Key Lab of Intelligent Information Processing, and School of Computer Science, Fudan University , Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jihong","family":"Guan","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Technology, Tongji University , Shanghai 201804, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1949-2768","authenticated-orcid":false,"given":"Shuigeng","family":"Zhou","sequence":"additional","affiliation":[{"name":"Shanghai Key Lab of Intelligent Information Processing, and School of Computer Science, Fudan University , Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,3,26]]},"reference":[{"key":"2023061310575139300_btab195-B1","author":"Armitage","year":"2019"},{"key":"2023061310575139300_btab195-B2","author":"Cho","year":"2014"},{"key":"2023061310575139300_btab195-B3","doi-asserted-by":"crossref","first-page":"1757","DOI":"10.1021\/acs.jcim.6b00601","article-title":"Convolutional embedding of attributed molecular graphs for physical property prediction","volume":"57","author":"Coley","year":"2017","journal-title":"J.
