基于LBSN的个性化旅游包推荐系统

摘要

Travel has become an important part in our daily lives , but making travel plans is not easy .Location Based Social Net-works(LBSN) provides a large amount of information about location and activity , which is useful for location search and recom-mendation.This paper proposes a LBSN-based personalized travel package recommendation system to help users make travel plans.We generate location profile and user preference model based on the collected LBSN data .Then we produce travel routes under spatio-temporal constraints and recommend the travel packages .The travel package contains travel destinations and visiting order of these destinations .%旅游是人们生活中的重要部分，但是制定旅游计划是一件繁杂的工作。基于位置的社交网络（ LBSN）的发展，提供了大量关于位置和活动的信息。为辅助用户制订旅游计划，本文提出一个基于LBSN的个性化旅游包推荐系统。该系统利用采集自LBSN的数据，建立地点和用户偏好模型，根据用户需求，在时空约束下生成旅游路线，形成旅游包推荐给用户。本文实现的原型系统能交互地获取用户旅游意向，实时生成多个旅游包供用户选择，对游客制订旅游计划具有一定的参考价值。
