摘要

针对个性化自驾游路径规划中存在规划路径无法满足不同用户个性化需求的问题，提出了基于不同用户兴趣点的关键词覆盖最优路径规划方法。首先，建立路网信息预处理模型并通过路网信息预处理算法绘制路网信息查询图；其次，使用倒排索引算法根据用户设定的个性化需求对路网信息查询图进行剪枝，在减小大规模数据处理内存开销的同时提升了关键词覆盖最优路径规划方法的执行效率；最后，通过双向并行拓展方式的关键词覆盖最优路径拓展算法实现满足用户兴趣点的个性化旅游路径推荐。实验结果表明，关键词覆盖最优路径规划方法不仅实现了满足用户个性化需求的路径规划，而且通过剪枝和双向并行拓展的方式提高了方法的执行效率。

Abstract

Focused on the problem that the planned routes cannot meet the personalized demand of different users in route planning of personalized self-driving tour

a keyword-aware optimal route planning method based on different user interests was proposed.Firstly

the road network information preprocessing model was set up and the road network information query graph was built by the road network information preprocessing algorithm.Secondly

the inverted index algorithm was proposed to prune the road network information query graph according to the personalized requirements from users

which improved the execution efficiency of keyword-aware optimal route planning method and reduced the memory cost of large-scale data processing effectively.Finally

the keyword-aware optimal route planning algorithm was proposed to realize personalized recommendation according to user interest by bidirectional parallel extension.The experimental results show that the method not only realizes the route planning to meet the individual needs of users but also improves the execution efficiency of the method through pruning and bidirectional parallel extension.
