Many recommendation methods are designed to solve this problem. The main contributions of recommendation methods proposed in this paper are as follows: (1) An improved collaborative filtering recommendation algorithm based on user clustering is proposed. Clustering is performed according to user similarity based on the user-item rating matrix. So the search space of recommendation algorithm is reduced. (2) Considering the factor that user\u2019s interests may dynamically change over time, a time decay function is introduced. (3) A method of real-time recommendation based on topic for microblogs is designed to realize real-time recommendation effectively by preserving intermediate variables of user similarity. Experiments show that the proposed algorithms have been improved in terms of running time and accuracy. <\/jats:p>","DOI":"10.1142\/s0218001420590065","type":"journal-article","created":{"date-parts":[[2019,4,26]],"date-time":"2019-04-26T01:37:11Z","timestamp":1556242631000},"page":"2059006","source":"Crossref","is-referenced-by-count":0,"title":["An Improved Real-Time Recommendation for Microblogs Based on Topic"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1796-137X","authenticated-orcid":false,"given":"Yikui","family":"Shi","sequence":"first","affiliation":[{"name":"Tai\u2019an Power Supply Company of State Grid Corporation of China, Tai\u2019an ShanDong, P.\u00a0R.\u00a0China"}]},{"given":"Jiyan","family":"Liu","sequence":"additional","affiliation":[{"name":"Tai\u2019an Power Supply Company of State Grid Corporation of China, Tai\u2019an ShanDong, P.\u00a0R.\u00a0China"}]},{"given":"Lei","family":"Shi","sequence":"additional","affiliation":[{"name":"Tai\u2019an Power Supply Company of State Grid Corporation of China, Tai\u2019an ShanDong, P.\u00a0R.\u00a0China"}]},{"given":"Jianwen","family":"Zhao","sequence":"additional","affiliation":[{"name":"Tai\u2019an Power Supply Company of State Grid Corporation of China, Tai\u2019an ShanDong, P.\u00a0R.\u00a0China"}]},{"given":"Na","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, ShanDong University of Science and Technology, Tai\u2019an ShanDong, P.\u00a0R.\u00a0China"}]}],"member":"219","published-online":{"date-parts":[[2019,6,25]]},"reference":[{"key":"S0218001420590065BIB001","first-page":"1665","volume":"25","author":"Ailin D.","year":"2004","journal-title":"Mini-Micro Syst."},{"key":"S0218001420590065BIB002","doi-asserted-by":"publisher","DOI":"10.1007\/s10115-014-0771-x"},{"key":"S0218001420590065BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2017.09.027"},{"key":"S0218001420590065BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.chb.2014.12.011"},{"issue":"12","key":"S0218001420590065BIB005","first-page":"3747","volume":"29","author":"DongFang D.","year":"2018","journal-title":"J.
