A key problem in many graph-based applications is the need to know, given a directed graph G and two vertices u,v ∈ G, whether there is a path between u and v, i.e., if u reaches v. This problem is particularly challenging in the case of very large real-world graphs. A common approach is the preprocessing of the graphs, in order to produce an efficient index structure, which allows fast access to the reachability information of the vertices. However, the majority of existing methods can not handle very large graphs. We propose, in this paper, a novel indexing method called FELINE (Fast rEfined onLINE search), which is inspired by Dominance Graph Drawing. FELINE creates an index from the graph representation in a two-dimensional plane, which provides reachability information in constant time for a significant portion of queries. Experiments demonstrate the efficiency of FELINE compared to state-of-the-art approaches.
