Similarity measures are the core component used by the neighborhood based collaborative filtering recommendations to predict the user's ratings in item-based or user-based recommender algorithms. The collaborative filtering has been implemented with different similarity measures but ignores to consider the time taken by the similarity measures to make accurate predictions in different application domains. This paper intended to help recommender systems developers to identify suitable similarity measure depending upon the application domain to be used with less execution time and error rate. It also takes the effect of neighbrhood sizes (k) on the prediction accuracy and efficiency into consideration. The experimental evaluations were conducted on the four similarity measures with the same dataset using Python programming language implementation. The evaluation metrics considered during the experiments are Execution Time, Mean Absolute Error (MAE) and Root Mean Square Error (RMSE). The results of the evaluation demonstrated that, Manhattan Distance similarity measure had the best accuracy as well as the efficiency of predictions in this study.

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
