Contextual information is proven helpful to recommender system. And context-aware recommender system(CARS) has been applied in various applications. To improve the accuracy of context-aware recommendation and make recommender application development easier, we develop a lightweight software framework named ConRec, which introduces a dynamic context oriented approach to extend traditional reduction...
With the development of cloud computing and mobile Internet, the issues related to big data have been concerned by both academe and industry. Based on the analysis of the existed work, the research progress of how to use distributed file system to meet the challenge in storing big data is expatiated, including four key techniques: storage of small files, load balancing, copy consistency, and de-duplication...
In IEEE 802.22 WRAN networks, spectrum sharing among different cells is an important problem. Aiming at efficiently solving the spectrum sharing problem, a dynamic channel auction scheme is proposed in this paper. Based on auction theory in microeconomics, the proposed algorithm models the spectrum sharing as an auction problem which includes one auctioneer base station and multiple bidder base stations...
In this paper, a random meeting algorithm is introduced into ant colony system. This algorithm can improve the quality of the antpsilas tour and can be used to make tour route planning. The improved calculating method of distance can balance the load in scenic spots and has the capability of dynamic route planning. The experimental results show that the proposed algorithm is effective and practical.
