Abstract

We present an interactive trip planning system called @FINDER which uses an exemplar trajectory query to find the most related top-k spatial-textual trajectories. @FINDER is implemented to support various degrees of user information needs for trip planning. For users with zero knowledge about places to travel, @FINDER provides a heatmap of popular points of interest (POIs) as well as popular activities from a trajectory database. The system helps users quickly explore the places, and helps formulate an exemplar trajectory query, which specifies preferred places to go and activities of interest. Then @FINDER provides efficient query processing of the top-k related spatial-textual trajectories using a new approach to spatial-textual trajectory indexing recently developed at RMIT University. For each of the top-k results found in the form of a set of POIs and activities, @FINDER further computes the optimal route (in term of the travel time) covering all of the POIs, and returns an album to the user. Lastly, users can further interact with @FINDER by adding or deleting POIs/activities in the original exemplar query, and the system will update the results in a timely manner.
使用活动轨迹的交互式旅行计划
我们提出了一个名为@FINDER的交互式旅行规划系统,该系统使用示例轨迹查询来查找最相关的top-k空间文本轨迹。@FINDER的实现是为了支持用户对旅行计划的不同程度的信息需求。对于对旅游地点一无所知的用户,@FINDER提供了热门兴趣点(poi)的热图,以及来自轨迹数据库的热门活动。该系统帮助用户快速探索地点,并帮助制定一个范例轨迹查询,指定首选的地方和感兴趣的活动。然后,@FINDER使用RMIT大学最近开发的一种新的空间文本轨迹索引方法,为top-k相关的空间文本轨迹提供高效的查询处理。对于以一组poi和活动的形式找到的前k个结果,@FINDER进一步计算覆盖所有poi的最佳路线(根据旅行时间),并向用户返回一个相册。最后,用户可以通过在原始示例查询中添加或删除poi /活动来进一步与@FINDER进行交互,系统将及时更新结果。
