Incremental top-k keyword queries in directed road networks

Muhammad Attique, Tae-Sun Chung
2018 2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)  
Therefore, in this paper, we present an algorithm called eSPAK that can efficiently answer the top-k spatial keyword queries in directed road networks.  ...  However, few algorithms study top-k keyword queries in undirected road networks where every road segment is undirected.  ...  Top-k spatial keywords in directed road networks are useful for location-based applications.  ...
