Recommending new friend relationships through accurate link prediction is one of the important factors in the evolution, development, and popularization of social networks. At present, scholars have proposed many link prediction algorithms based on the similarity of local information and random walks. These algorithms help identify actual missing and false links in various networks. However, the prediction results significantly differ in networks with various structures, and the prediction accuracy is low. This study proposes a method for improving the accuracy of link prediction. Before link prediction, <jats:italic>k<\/jats:italic>\u2010shell decomposition method is used to layer the network, and the nodes that are in 1\u2010shell and the nodes that are not linked to the high\u2010shell in the 2\u2010shell are deleted. The experiments on four real network datasets verify the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1155\/2021\/8889441","type":"journal-article","created":{"date-parts":[[2021,5,24]],"date-time":"2021-05-24T21:05:06Z","timestamp":1621890306000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Method for Improving the Accuracy of Link Prediction Algorithms"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5271-8263","authenticated-orcid":false,"given":"Jie","family":"Li","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8015-3688","authenticated-orcid":false,"given":"Xiyang","family":"Peng","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1281-2287","authenticated-orcid":false,"given":"Jian","family":"Wang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6166-2118","authenticated-orcid":false,"given":"Na","family":"Zhao","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,5,24]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1145\/1117454.1117456"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature06830"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10489-017-0933-0"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2017.02.003"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1158684"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1098\/rsta.2012.0378"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/0022250x.1971.9989788"},{"key":"e_1_2_8_8_2","first-page":"547","article-title":"Bulletin de la soci\u00e9t\u00e9 vaudoise des sciences naturelles","volume":"37","author":"Jaccard P.","year":"1901","journal-title":"Etude Comparative de la Distribution florale dans une Portion des Alpes et des Jura"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0378-8733(03)00009-1"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1140\/epjb\/e2009-00335-8"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.286.5439.509"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1103\/physreve.80.046122"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physa.2017.02.078"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.3390\/e21090863"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/bf02289026"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/bf01164627"},{"key":"e_1_2_8_17_2","doi-asserted-by":"publisher","DOI":"10.1109\/tkde.2007.46"},{"key":"e_1_2_8_18_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-019-09177-y"},{"key":"e_1_2_8_19_2","doi-asserted-by":"publisher","DOI":"10.1038\/nphys1746"},{"volume-title":"The Stanford GraphBase: A Platform for Combinatorial Computing","year":"1993","author":"Knuth D.
