Abstract
Web page recommendations have attracted increasing attention in recent years. Web page recommendation has different characteristics compared to the classical recommenders. For example, the recommender cannot simply use the user-item utility prediction method as e-commerce recommendation, which would face the repeated item cold-start problem. Recent researches generally classify the web page articles before recommending. But classification often requires manual labors, and the size of each category may be too large. Some studies propose to utilize clustering method to preprocess the web page corpus and achieve good results. But there are many differences between different clustering methods. For instance, some clustering methods are of high time complexity; in addition, some clustering methods rely on initial parameters by iterative computing whose results probably aren’t stable. In order to solve the above issues, we propose a web page recommendation based on twofold clustering by considering both effectiveness and efficiency, and take the popularity and freshness factors into account. In our proposed clustering, we combined the strong points of density-based clustering and the k-means clustering. The core idea is that we used the density-based clustering in sample data to get the number of clusters and the initial center of each cluster. The experimental results show that our method performs better diversity and accuracy compared to the state-of-the-art approaches.
