Paper Title
A Time-based Recommendation System using a Sequential Pattern Matching Method

Abstract
Recommender systems have significant applications in both industry and academia. Collaborative filtering methods are the most widely used in industrial applications. These algorithms utilize preferences of similar users to provide suggestions for a target user. Although the users’ preferences may vary over time, traditional collaborative filtering algorithms fail to consider this important issue. Sequential pattern of ratings is another important factor which disregarded by collaborative filtering. In this paper, a novel recommendation method is proposed based on a sequential pattern matching approach. The proposed method takes into account the time of ratings to calculate similarity values. Experimental results on a benchmark dataset show that the proposed method significantly outperforms other recommendation methods. Index Terms - Recommendation System, Sequential Pattern Matching, Similarity Measure, Time.
