基于新颖性和多样性的旅游推荐模型研究
Research on tourism recommendation model based on novelty and diversity
摘要
Abstract
Recommendation system is widely used in people’s travel activity, for example, recommendation of travel route and hotel. However, such kind of recommendation is mostly based on Top-N hot item recommendation, which leads to the fact that tourists end up with so-called accurate recommendation without any detailed information. This paper aims at the problem caused by over emphasis on recommendation accuracy in traditional recommendation algorithm that results in little novelty and diversity. It puts MMR into the application of tourism recommendation, and adds in user-item interac-tion parameter, thus putting forward a new recommendation system based on relationship between the user and the item. This new system undertakes tests in real data collection and compared with traditional KNN and classic MMR-based algo-rithm, effectively enhances the novelty and diversity of recommendation list. In such tourism recommendation field which requires higher novelty, this algorithm outweighs, to a certain extent, the traditional one.关键词
