Traditional venue and tour recommendation systems do not necessarily provide a diverse set of recommendations and leave little room for serendipity . In this article, we design MPG, a Mobile Personal Guide that recommends: (i) a set of diverse yet surprisingly interesting venues that are aligned to user preferences and (ii) a set of routes, constructed from the recommended venues. We also introduce EPUI, an Experimental Platform for Urban Informatics. Our comparison with the state-of-the-art schemes indicates that MPG is capable of providing high-quality venues and route recommendations while incorporating seamlessly both the notion of diversity and that of serendipity.

基于偶然性的兴趣点导航

传统的场地和旅游推荐系统不一定提供各种各样的一套建议，并没有留下多少空间机缘巧合. 在本文中，我们设计了 MPG，这是一种移动个人指南，它建议：(i) 一组符合用户偏好的多样化但令人惊讶的有趣场所，以及 (ii) 一组路线，由推荐的场所构成。我们还介绍了城市信息学实验平台 EPUI。我们与最先进的方案的比较表明，MPG 能够提供高质量的场地和路线推荐，同时无缝地结合多样性和偶然性的概念。
