Interpreting Place Descriptions for Navigation Services

In human route communication, people describe places in natural language. These place descriptions are flexible, potentially vernacular and ambiguous descriptions of places, and in the context of route communication, of start or destination places. The main components are placenames and spatial relations. People are able to interpret human place descriptions, however current navigation services can not handle human place descriptions in general. Consequently the initial phase of communication between human wayfinders and navigation services—finding an agreement on start and destination—is broken. Without the agreement, no direction information can be provided, and the communication can not be closed successfully. We see a need for research bringing spatial intelligence into the fundamental mechanisms of parsing and interpreting place descriptions. An intelligent navigation service will have capabilities to imitate human route communication behavior (Winter and Wu, 2009), thus, at least the capabilities to make sense of place descriptions.
