Modeling Spatial Knowledge from Verbal Descriptions
نویسندگان
چکیده
Over the past few years, several alternative approaches have been suggested to represent the spatial knowledge that emerges from natural environments. This paper introduces a rule-based approach whose objective is to generate a spatial semantic network derived from several humans reporting a navigation process in a natural environment. Verbal descriptions are decomposed and characterized by a graph-based model where actions and landmarks are the main abstractions. A set of rules implemented as first order predicate calculus are identified and applied, and allow to merge the common knowledge inferred from route descriptions. A spatial semantic network is derived and provides a global and semantic view of the environment. The whole approach is illustrated by a case study and some preliminary experimental results.

Saliency Cognition of Urban Monuments Based on Verbal Descriptions of Mental-Spatial Representations (Case Study: Urban Monuments in Qazvin)
Urban monuments encompass a wide range of architectural works either intentionally or unintentionally. These works are often salient due to their inherently explicit or hidden components and qualities in the urban context. Therefore, they affect the mental-spatial representations of the environment and make the city legible. However, the ambiguity of effective components often complicates their...
متن کاملVerbal Assistance in Tactile-Map Explorations: A Case for Visual Representations and Reasoning
Tactile maps offer access to spatial-analog information for visually impaired people. In contrast to visual maps, a tactile map has a lower resolution and can only be inspected in a sequential way, complicating the extraction of spatial relations among distant map entities. Verbal assistance can help to overcome these difficulties by substituting textual labels with verbal descriptions and offe...
متن کاملKnowledge, Practice, Activities and People
The perspective of modeling knowledge in Artificial Intelligence is that these models are equal to the knowledge itself (e.g. equate the map with the territory). This encoding view treats knowledge as if it were primarily verbal and assumes that verbal concepts themselves can be replaced by descriptions of concepts--as if a body of descriptions and neural categorizations were equivalent mechani...
متن کاملA semantic and language-based representation of an environmental scene
The modeling of a landscape environment is a cognitive activity that requires appropriate spatial representations. The research presented in this paper introduces a structural and semantic categorization of a landscape view based on panoramic photographs that act as a substitute of a given natural environment. Verbal descriptions of a landscape scene provide the modeling input of our approach. ...
متن کاملThe attentive robot companion: learning spatial information from observation and verbal interaction
This doctoral thesis investigates how a robot companion can gain a certain degree of situational awareness through observation and interaction with its surroundings. The focus lies on the representation of the spatial knowledge gathered constantly over time in an indoor environment. However, from the background of research on an interactive service robot, methods for deployment in inference and...
