顾及道路通达性和时间成本的多用户位置推荐

Multi-user Location Recommendation Considering Road Accessibility and Time-Cost

  • 摘要: 位置推荐是地理社交网络的重要应用,针对城市范围内多用户集体社交活动的规划需求,在顾及道路通达性和时间成本的情况下进行位置推荐算法的研究。针对城市路网结构特征和导航路线规划特点,在地图应用程序接口的支持下,利用各用户间导航路线上的特定点自动识别、构建区域实现位置推荐,平衡多个用户到推荐地点的可到达性和时间成本。实验结果验证了所提方法的有效性,在地理社交网络上可以为城市多用户的集体活动提供有效的位置推荐方案。

     

    Abstract: Location recommendation is an important application of location-based social network, Focused on the planning requirement for multi-user group social activities in urban area, and taking into account of urban road accessibility and user's time-cost of participation in activities, based on the characteristics of urban road network structure and navigation route planning, an algorithm for multi-user location recommendation has been suggested, in which the position is recommended in polygon region that is automatically recognized and constructed by making use of specific points in inter-user navigation route in support of map application programming interface, in order to balance the accessibility and time-cost from multi-user to recom-mended location. The validity of the suggested approach has been verified by a test system developed by the authors, this method can provide an effective location recommendation scheme for urban multi-user collective activities on location-based social networks.
