The conventional CF approach has limitations, namely data sparsity and cold-start. The matrix decomposition approach is demonstrated to be one of the effective approaches used in developing recommendation systems. This paper presents a new approach that uses CF and Singular Value Decomposition (SVD)[Formula: see text] for implementing a recommendation system. Therefore, this work is an attempt to extend the existing recommendation systems by (i) finding similarity between user and item from rating matrices using cosine similarity; (ii) predicting missing ratings using a matrix decomposition approach, and (iii) recommending top-N user-preferred items. The recommender system\u2019s performance is evaluated considering Root Mean Square Error (RMSE) and Mean Absolute Error (MAE). Performance evaluation is accomplished by comparing the systems developed using CF in combination with six different algorithms, namely SVD, SVD[Formula: see text], Co-Clustering, KNNBasic, KNNBaseline, and KNNWithMeans. We have experimented using MovieLens 100[Formula: see text]K, MovieLens 1[Formula: see text]M, and BookCrossing datasets. The results prove that the proposed approach gives a lesser error rate when cross-validation ([Formula: see text]) is performed. The experimental results show that the lowest error rate is achieved with MovieLens 100[Formula: see text]K dataset ([Formula: see text], [Formula: see text]). The proposed approach also alleviates the sparsity and cold-start problems and recommends the relevant items. <\/jats:p>","DOI":"10.1142\/s0219622021500310","type":"journal-article","created":{"date-parts":[[2021,4,19]],"date-time":"2021-04-19T03:26:27Z","timestamp":1618802787000},"page":"1075-1093","source":"Crossref","is-referenced-by-count":37,"title":["Rec-CFSVD++: Implementing Recommendation System Using Collaborative Filtering and Singular Value Decomposition (SVD)++"],"prefix":"10.1142","volume":"20","author":[{"given":"Taushif","family":"Anwar","sequence":"first","affiliation":[{"name":"Department of Computer Science, School of Engineering and Technology, Pondicherry University, Pondicherry 605014, India"}]},{"given":"V.","family":"Uma","sequence":"additional","affiliation":[{"name":"Department of Computer Science, School of Engineering and Technology, Pondicherry University, Pondicherry 605014, India"}]},{"given":"Gautam","family":"Srivastava","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Computer Science, Brandon University, Brandon, MB R7A 6A9, Canada"},{"name":"Research Centre for Interneural Computing, China Medical University, Taichung 40402, Taiwan, ROC"}]}],"member":"219","published-online":{"date-parts":[[2021,4,17]]},"reference":[{"key":"S0219622021500310BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.2975167"},{"key":"S0219622021500310BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/TLA.2017.7867596"},{"key":"S0219622021500310BIB003","doi-asserted-by":"publisher","DOI":"10.4018\/IJWP.2018010104"},{"key":"S0219622021500310BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/CONFLUENCE.2019.8776969"},{"key":"S0219622021500310BIB005","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-13-8676-3_17"},{"key":"S0219622021500310BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2017.09.058"},{"key":"S0219622021500310BIB007","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-41368-2_7"},{"key":"S0219622021500310BIB008","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-13-6347-4_1"},{"key":"S0219622021500310BIB009","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2019.01.036"},{"key":"S0219622021500310BIB010","doi-asserted-by":"publisher","DOI":"10.1142\/S0219622011004452"},{"issue":"1","key":"S0219622021500310BIB011","first-page":"126","volume":"9","author":"Mohammed N.
